The Regulatory Status of Functional Foods in the Economic Integration Organizations of Latin America and the Caribbean / El Estatus Regulatorio de los Alimentos Funcionales en las Organizaciones de Integración Económica de Latinoamérica y el Caribe

Introduction. The legal declarations on functional foods of the four main economic integration organizations in Latin America and the Caribbean (LAC) ­ Pacific Alliance (PA), Caribbean Community (CARICOM), Southern Common Market (MERCOSUR) and Central American Integration System (SICA) - are based on the Codex Alimentarius system and do not regulate functional foods. The use of Codex in food marketing is an insufficient condition for its application in functional foods. Regulation based on scientific and technology results are required to be used in the economic integration organizations of LAC. Objective. The objective is to analyze the theoretical framework of the legal foundations that could govern the commercialization processes of functional foods, whose research advances have currently only been manifested in nutritional health. This article also seeks to address this gap through a systematic analysis of international regulations. Materials and methods. For this, a review of the literature emanating from two databases from 2018-2023 is carried by applying the legal-economic research method of documentary content analysis, applied to three general food marketing regulations: food safety declarations, regulations for inspections, food manufacturing and food labeling. Results. The results reveal the absence of specific legislation for functional foods in LAC economic integration organizations. Conclusions. The legal principle of marketing based on peremptory norm (also called jus cogens) can be facilitated through side letters, included in the contents of international contracts. along with the registration requirements of industrial property rights of the member countries associations(AU)

Introducción. Las declaraciones legales sobre alimentos funcionales de las cuatro principales organizaciones de integración económica de América Latina y el Caribe (ALC) ­ Alianza del Pacífico (AP), Comunidad del Caribe (CARICOM), Mercado Común del Sur (MERCOSUR) y Sistema de Integración Centroamericana (SICA) - se basan en el sistema del Codex Alimentarius y no regulan los alimentos funcionales. El uso del Codex en la comercialización de alimentos es condición insuficiente para su aplicación en alimentos funcionales. Se requiere que las regulaciones basadas en resultados científicos y tecnológicos sean utilizadas en los organismos de integración económica de ALC. Objetivo. Analizar el marco teórico de los fundamentos legales que podrían regir los procesos de comercialización de alimentos funcionales, cuyos avances en investigación actualmente solo se han manifestado en salud nutricional. Este artículo también busca abordar esta brecha a través de un análisis sistemático de las regulaciones internacionales. Materiales y métodos. Se realiza una revisión de la literatura emanada de dos bases de datos del período 2018-2023 aplicando el método de investigación jurídico- económica de análisis de contenido documental, aplicado a tres normas generales de comercialización de alimentos: declaraciones de seguridad alimentaria, normas para inspecciones, fabricación de alimentos y etiquetado de alimentos. Resultados. Los resultados revelan la ausencia de legislación específica para alimentos funcionales en las asociaciones comerciales de ALC. Conclusiones. El principio jurídico de comercialización basado en norma imperativa (también llamado jus cogens) puede facilitarse a través de cartas complementarias, incluidas en el contenido de los contratos internacionales. junto con los requisitos de registro de los derechos de propiedad industrial de las asociaciones de los países miembros(AU)

Microbiota intestinal y cólicos infantiles: ¿hay lugar para los prebióticos, probióticos y posbióticos? / Gut Microbiota and Infant Colic: is there a Place for Prebiotics, Probiotics, and Postbiotics?

El consumo de probióticos, prebióticos y posbióticos, o su combinación, puede contribuir a mantener una microbiota intestinal saludable ya que permite la regulación de su disbiosis en el caso de algunas enfermedades o trastornos, principalmente en los trastornos gastrointestinales funcionales (TGIF). El microbioma intestinal es protagonista esencial en la fisiopatología de los TGIF a través de sus funciones metabólicas y nutricionales, el mantenimiento de la integridad de la mucosa intestinal y la regulación de la respuesta inmunitaria. Las investigaciones realizadas hasta la fecha indican que los probióticos, prebióticos y posbióticos pueden tener efectos inmunomoduladores directos y clínicamente relevantes. Existen pruebas del uso de esta familia de bióticos en individuos sanos para mejorar la salud general y aliviar los síntomas en una serie de enfermedades como los cólicos infantiles. La colonización y establecimiento de la microbiota comienza en el momento del nacimiento; los primeros 2-3 años de vida son fundamentales para el desarrollo de una comunidad microbiana abundante y diversa. Diversos estudios científicos realizados mediante técnicas tradicionales dependientes de cultivo y más recientemente por técnicas moleculares han observado diferencias en las poblaciones bacterianas de bebés sanos y aquellos que sufren TGIF, estos últimos caracterizados por un aumento de especies patógenas y una menor población de bifidobacterias y lactobacilos, en comparación con los primeros. En tal contexto, se considera que la microbiota intestinal como protagonista en el desarrollo de esos trastornos, entre ellos los cólicos infantiles, a través de sus funciones metabólicas, nutricionales, de mantenimiento de la integridad de la mucosa intestinal y regulación de la respuesta inmunitaria. Esto ha abierto la puerta al estudio de la utilización de prebióticos, probióticos y posbióticos en el tratamiento y/o prevención de los TGIF infantiles. El parto vaginal y de término así como la lactancia son fundamentales en la constitución de una microbiota saludable. Como herramientas de apoyo, existen estudios de eficacia que sustentan la administración de esta familia de bióticos, principalmente en los casos en que la lactancia no sea posible o esté limitada.

The consumption of probiotics, prebiotics, and postbiotics, or a combination of them, can contribute to maintaining a healthy intestinal microbiota as it allows the regulation of its dysbiosis in the case of some diseases or disorders, mainly in functional gastrointestinal disorders (FGIDs). The gut microbiome is an essential player in the pathophysiology of FGIDs through its metabolic and nutritional functions, the maintenance of intestinal mucosal integrity, and the regulation of the immune response. Research results thus far indicate that probiotics, prebiotics, and postbiotics may have direct and clinically relevant immunomodulatory effects. There is evidence regarding the prescription of this family of biotics in healthy individuals to improve overall health and alleviate symptoms in many conditions like infantile colic. The colonization and microbiota establishment begins at birth; the first 2-3 years of life are critical for developing an abundant and diverse microbial community. Several scientific studies performed by traditional culture-dependent techniques and more recently by molecular techniques have observed differences in the bacterial populations of healthy infants and those suffering from FGIDs, the latter characterized by an increase in pathogenic species and a lower population of bifidobacteria and lactobacilli, compared to the former. In this context, the intestinal microbiota plays a leading role in the onset of these disorders, including infantile colic, through its metabolic and nutritional functions, maintenance of the integrity of the intestinal mucosa, and regulation of the immune response. That has opened the door to the study of prebiotics, probiotics, and postbiotics usage in the treatment and or prevention of infantile FGIDs. Vaginal and term delivery and breastfeeding are fundamental in the constitution of a healthy microbiota. As supportive tools, there are efficacy studies that support the administration of this family of biotics, mainly in cases where lactation is not possible or is limited.

Alegação de propriedades funcionais aumentam a aceitação de muesli de aveia por consumidores / Functional claim increases the acceptance of oat muesli by consumers

Introdução: Mueslis de aveia contêm betaglucanas, uma fibra solúvel com propriedades hipocolesterolêmicas e hipoglicêmicas. Os benefícios do muesli de aveia podem ser alegados em produtos para atrair potenciais consumidores. Objetivos: Este estudo avaliou a influência de uma alegação funcional na aceitação de um muesli de aveia. Além disso, avaliou-se o efeito da aveia do muesli sobre as percepções de saciedade e humor. Métodos: Formularam-se dois produtos: muesli de aveia e muesli de flocos de arroz (controle), para a realização do estudo. Para os testes sensoriais, o muesli de aveia foi apresentado com duas codificações: uma com alegação de alimento funcional e outra sem alegação. Aos consumidores (n=160) foram abordadas questões sobre gosto, interesse de consumo e benefício antes e depois da degustação do mueslis, utilizando escalas hedônicas. Para entender os efeitos do muesli na saciedade e humor, foi realizado um ensaio clínico com 9 mulheres adultas saudáveis (aproximadamente 22 anos). Um desenho cruzado foi usado, com um período de washout de uma semana entre as intervenções. Os indivíduos preencheram um questionário de humor e saciedade usando escalas analógicas visuais antes e após consumir o mueslis no café da manhã. Resultados: O muesli de aveia com alegação foi apontado como o produto mais benéfico entre as amostras (p<0,05), apresentando maiores escores para gosto e interesse de uso. O consumo de muesli de aveia não influenciou o humor e a saciedade dos participantes pois não foram encontradas diferenças significativas entre as intervenções (p>0,05). Conclusão: A alegação funcional influenciou a aceitação dos benefícios do muesli de aveia para a saúde dos consumidores.

Background: Oats-based mueslis contain beta-glucans, a type of soluble fiber known for its hypocholesterolemic and hypoglycemic properties. The claim of these health benefits, oat muesli products may attract potential consumers. Objectives: This study aimed to assess the impact of a functional claim on consumers' acceptance and attitudes toward oat muesli. Additionally, the study evaluated the effects of muesli containing oats on satiety and mood perceptions. Methods: Two muesli products were formulated: one with oats and another with rice flakes (control) for sensory analysis. The oat muesli was presented with two codings (n=160): one with a functional food claim and another without the claim. Consumers were asked about their liking, interest in usage, and perceived benefits before and after tasting the mueslis using hedonic scales. Furthermore, a clinical trial was conducted with 9 healthy adult women subjects (average age 22 years) in a crossover design with a one-week washout period between interventions. The subjects completed a self-perceived mood and satiety questionnaire using visual analog scales (VAS) at Results: The oat muesli with the functional claim was perceived as the most beneficial product among the samples (p<0.05), receiving high scores for liking and interest in use. However, oat muesli consumption did not significantly influence participants' average mood and satiety during the trial (p>0.05), as no significant differences between interventions were found. Conclusion: The inclusion of a functional claim positively affected the acceptance of the health benefits associated with oat muesli.

Determination of cyanide in whole seeds and brans of linseed (Linum usitatissimum Linn) by molecular spectrophotometry

Abstract The addition of linseed (Linum usitatissimum Linn) in the diet, as a functional food, has increased over the years. However, it possesses cyanogenic glycosides. This study aimed to quantify and compare cyanide concentration in whole seed and bran of brown and golden types to establish a safe limit of intake. Three commercial labels, from brown and golden whole seed types (Ab, Ag, Bb, Bg, Cb and Cg), and six commercial labels of brown and golden bran (1b, 2g, 3g, 4b, 5g, and 6b), were selected, totalizing twelve samples. Total cyanide concentration was quantified by a colorimetric method employing alkaline picrate, after acid hydrolysis. The whole seed cyanide values were between 348.4 and 473.20 µg/g and the bran cyanide values were between 459.53 and 639.35 µg/g. The analyzed bran presented increased cyanide concentrations than the whole seeds with no differences between brown and golden types. Food able to produce cyanide less than 90 µg/kg body weight, daily, is considered secure for consumption. Considering this limit and analyzed samples, it is safe to eat approximately two tablespoons of seeds or one tablespoon of bran. These results point out the importance of cyanide amount daily intake information to be in linseed packaging, to ensure secure consumption

Evaluation of the nutritional composition and antioxidant activity of Bjerkandera adusta

Abstract Bjerkandera adusta, a globally distributed fungus, is commonly used in the nutritional practices of the East Asian population. In this study, we evaluated the nutritional composition of the lyophilized mycelium of B. adusta as well as the phenolic composition and antioxidant activity of its extracts. The mycelium exhibited moisture (7.97 %), ash (3.27 %), and fiber (5.31 %) content values similar to the established values reported in the available literature. In addition, a high protein (9.32 %) and carbohydrate (63.45 %) content was shown, with a low lipid (1.36 %) content. The energy value per 100 g sample of mycelium was 1445.85 kJ. The results obtained indicated a statistically significant variation (p < 0.05) in the phenolic composition (81.84-110.96 mg gallic acid equivalents (GAE) per g of extract), free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity (IC50 29.05-340.46 µg·mL-1), phosphomolybdenum antioxidant content (34.89-55.64 %), reduction of ferricyanide ion (66.55-69.4 %), and thiobarbituric acid reactive substance (TBARS) values (44.66-133.03 %). These results are unprecedented for this species and emphasize its nutraceutical potential.

Health benefits of Kombucha: drink and its biocellulose production

Abstract Kombucha (tea and biocelluose) has been used worldwide due to its high nutritional, functional, and economic potential. This fermented tea has been used in folk medicine to treat several pathological conditions and its biocellulose in the industrial sector. In this context, this paper presents a scientific literature review on the main phytochemicals of Kombucha and respective biological activities to assess their potential uses. The tea has presented a wide range of bioactive compounds such as amino acids, anions, flavonoids, minerals, polyphenols, vitamins, and microorganisms. Moreover, its biocellulose is rich in fibers. These compounds contribute to various biological responses such as antioxidant, hepatoprotective, antitumoral, antidiabetic, and antihypercholesterolemic effects. In this sense, both the tea and its biocellulose are promising for human use. Besides, Kombucha presents itself as a drink option for vegetarians and/or those seeking healthier diets, as its biocellulose can bring metabolic benefits. Our review demonstrates that both can be used as functional foods and/or sources of bioactive compounds for food and industrial applications.

Objetivo: Determinar el efecto de Lactobacillus plantarum microencapsulado sobre parámetros intestinales e inmunológicos en pollos de engorde. Materiales y métodos: A 240 pollos Ross-308-AP de un día de nacidos se suministró alimento con o sin adición de probiótico bajo el siguiente modelo: sin probiótico-(T0), con probiótico comercial-(T1), con L. plantarum microencapsulado-(T2) y sin microencapsular-(T3). L. plantarum ATCC-8014 se microencapsuló mediante secado por aspersión, determinando su viabilidad en (%). Se evaluaron parámetros intestinales, morfo-histopatológicos e inmunológicos por Azul de Alcian, microscopia de barrido e inmunohistoquímica y la abundancia microbial por UFC/mL. Resultados: El microencapsulado confirió una viabilidad in vivo de L. plantarum del 88,1%. El tratamiento T2 mejoró los parámetros inmunológicos y confirió beneficios intestinales con una abundancia de bacterias benéficas (Lactobacillus) de (9,13x105-UFC/mL), significativamente mayor a la encontrada en los tratamientos T1 (8,91x105) y T3 (8,23x105) y el control T0 (9,18x104), (p<0,05). Conclusiones: La adición de L. plantarum microencapsulado en alimento para pollos mejora parámetros inmunológicos y confiere mayor abundancia de bacterias benéficas presentes en la microbiota intestinal.

Introduction: Usage of growth-promoting antibiotics in poultry production is limited due to the increase in bacterial resistance. An alternative to assess microencapsulated probiotics and their effect on gut health is presented in this study. Objective: To determine the effect of microencapsulated L. plantarum on intestinal and immunological parameters in broilers. Materials and methods: 240 Ross-308-AP chickens (one day old) were fed with or without the addition of a probiotic, under the following model: without probiotic (T0); with commercial probiotic (T1); with probiotic containing either microencapsulated (T2) or non-microencapsulated (T3) L. plantarum. ATCC-8014 was microencapsulated by spray drying, assessing its viability in (%). Alcian blue, scanning microscopy, and immunohistochemistry were used to evaluate intestinal, morpho-histopathological, and immunological parameters. Microbial abundance was quantified by UFC/ml. Results: Microencapsulation of L. plantarum induced an 88.1% in vivo viability. T2 treatment improved both immunological parameters and the intestinal population of beneficial bacteria (Lactobacillus) (9.13x105 UFC/ml), which was significantly higher than that found in T1 (8.91x105), T3 (8.23x105), and control T0 (9.18x104), (p<0.05). Conclusion: Adding microencapsulated L. plantarum to chicken feed improves immunological parameters and increases the population of beneficial bacteria in the intestinal microbiota.

Nutrition and Cardiovascular Diseases: Programming and Reprogramming

Abstract The Developmental Origin of Health and Disease (DOHaD) is an area of science dedicated to studying the processes by which insults during critical periods of mammals development leading to physiological changes resultig in diseases throughout life. Studies point to a complex interaction between nutritional status in early life and cardiovascular system homeostasis in which maternal malnutrition during gestation and/or lactation, as well as early weaning, are associated with development of cardiovascular diseases in adulthood. In this context, epigenetic changes, such as DNA methylation, histone acetylation, and change in microRNA expression have been considered molecular bases of cellular plasticity, which can also be gender-dependent. Experimental studies have demonstrated that interventions encompassing the consumption of functional food/bioactive compounds, as well as energetic and nutrients adjustments on the diet, may attenuate or even prevent consequences associated with plasticity of development, improving cardiovascular health. This review aimed to gather and discuss the findings within this context, published over the last ten years.

Isoflavonas como tratamento alternativo na sintomatologia climatérica: uma revisão sistemática / Isoflavones as alternative treatment in climacteric symptomatology: a systematic review

O climatério é uma fase natural da vida da mulher que ocorre entre os 40 e 65 anos de idade e é caracterizado pela transição entre a fase reprodutiva e não reprodutiva. Neste período, devido às alterações hormonais, ocorrem alterações biológicas, endócrinas e clínicas. Sintomas vasomotores são típicos do hipoestrogenismo e podem interferir negativamente na qualidade de vida das mulheres. Este estudo teve como objetivo revisar os resultados dos estudos de intervenção que utilizaram isoflavonas na sintomatologia de mulheres climatéricas não usuárias de Terapia de Reposição Hormonal (TRH). Realizou-se uma revisão sistemática de artigos publicados entre os anos de 2008 e 2019 na base de dados PubMed. Foram encontrados 169 estudos, e considerando os critérios de inclusão, 18 artigos foram selecionados, em que houve intervenção com isoflavonas por meio de cápsulas e/ou suplementos ou alimentos para tratamento da síndrome climatérica. Foram verificados resultados positivos nos sintomas globais, com destaque para sintomas vasomotores, em mais da metade dos estudos avaliados, em que doses entre 45 mg a 160 mg diárias de isoflavonas por pelo menos 12 semanas foram administradas, especificadamente nas mulheres no período da pós-menopausa. (AU)

The climacteric is a natural phase during women's life, which occurs between 40 and 65 years. It is characterized by the transition from their reproductive to non-reproductive phase. In this period, due to hormonal changes, biological, endocrine and clinical modifications also occur. Vasomotor symptoms are characteristic of hypoestrogenism and can negatively affect women's quality of life. This study aimed to review the results of intervention studies which used isoflavones to treat the symptoms of climacteric women who did not undergo Hormone Replacement Therapy (HRT). A systematic review of articles published between 2008 and 2019 in the PubMed database was carried out. 169 studies were found, and considering the inclusion criteria, 18 articles were selected, in which it was described isoflavones intervention with capsules and/ or supplements or foods for the treatment of climacteric syndrome. Positive results were observed regarding to global symptoms, with emphasis on vasomotor symptoms in more than half of the studies, in which daily doses of isoflavones, between 45 mg to 160 mg, for at least 12 weeks, were administered specifically in postmenopausal women.

Análise da adequação do termo detox nos rótulos de bebidas industrializadas à base de frutas e vegetais / Analysis of the adequacy of the term detox on the labels of industrialized drinks based on fruits and vegetables

Dietas populares, como as detox, surgem a todo o momento. Todavia, poucos dados científicos comprovam a eficácia e segurança destas dietas. Este trabalho avaliou rótulos de bebidas à base de frutas e vegetais e identificou as que se autodenominam detox. Tratou-se de estudo transversal descritivo, realizado de setembro a outubro/2016. O tamanho da porção na informação nutricional e as alegações encontradas nos rótulos foram analisados em relação às legislações vigentes. Composição nutricional, quantidade total de ingredientes e presença de aditivos alimentares e/ou outros ingredientes não usuais em preparações culinárias foram comparados entre as bebidas detox e as comuns. De 83 produtos analisados, 9,6% (n=8) se autodenominaram detox. A composição nutricional e o número médio de ingredientes não diferiram entre as bebidas detox e as comuns. Alegações nutricionais e de saúde estavam presentes em 77,1% (n=64) dos produtos e 53,0% (n=44) apresentaram alegações não previstas na RDC nº 54/2012. As informações mais frequentes foram quanto aos teores de micronutrientes, açúcares, sódio e fibras. O termo detox, apesar de não permitido, é encontrado neste tipo de produto no mercado brasileiro. Os resultados sugerem que o termo detox seja utilizado mais como estratégia de marketing do que como real alegação de propriedade nutricional. (AU)

Popular diets, such as detox, appear all the time. However, few scientific data prove the efficacy and safety of these diets. This work evaluated labels of drinks based on fruits and vegetables and identified those that call detox. This was a descriptive cross-sectional study, carried out from September to October/2016. The portion size in the nutrition information and the claims found on the labels were analyzed in relation to the current legislation. Nutritional composition, total amount of ingredients and presence of food additives and other unusual ingredients in culinary preparations were compared between detox and ordinary drinks. Of 83 products analyzed, 9.6% (n=8) called detox. The nutritional composition and the average number of ingredients did not differ between detox drinks and ordinary drinks. Nutritional and health claims were present in 77.1% (n=64) of the products and 53.0% (n=44) presented claims not provided for in RDC nº 54/2012. The most frequent information was about the levels of micronutrients, sugars, sodium and fibers. The term detox, although not allowed, is found in this type of product in the Brazilian market. The results suggest that the term detox is used more as a marketing strategy than as a real claim of nutritional property. (AU)

Survival of commercial probiotic strains and their effect on dark chocolate synbiotic snack with raspberry content during the storage and after simulated digestion

BACKGROUND: A key challenge for manufacturers of pro-health food containing active probiotic microorganisms is to develop a product with attractive sensory features along with maintenance of declared number of microorganisms during storage and transfer by alimentary tract. RESULTS: The highest concentration of polyphenols was observed in snacks without an additive of probiotics as well as those with an additive of L. rhamnosus and B. animalis bacteria and concentration of these compounds increased by 9.5% during six months of storage. None of the products distinguished itself in the sensorial assessment although each was assessed positively. The number of microorganisms was stable and comparatively high during six months of storage at a room temperature and in cooling conditions (108 cfu/g). In the digestion model, an influence of aggressive digestion conditions was examined in the alimentary tract on the number of microorganisms, which allowed to arrange strains from the most resistant (S. boulardii) to the most sensitive (B. breve). It must be noted that currently on the market there is no available snack containing probiotic yeast as well as there is no literature data on works on such formulation of food. CONCLUSIONS: In the newly developed snack made of chocolate, in which sugar has been replaced with maltitol, a raw material was added in the form of raspberry, prebiotic in the form of inulin and a strain of probiotic bacteria, including the unprecedented so far S. boulardii, which stands a high chance to occupy a good place on the market of functional food.

Health-promoting activities of edible seaweed extracts from Chilean coasts: assessment of antioxidant, anti-diabetic, anti-inflammatory and antimicrobial potential / Actividades promotoras de la salud de extractos de algas comestibles de las costas chilenas: evaluación del potencial antioxidante, antidiabético, antiinflamatorio y antimicrobiano

ABSTRACT The aim of this study was to evaluate the antioxidant, antidiabetic, anti-inflammatory and antimicrobial activities of three edible seaweed extracts from Chilean coasts: Pyropia orbicularis, Ulva spp, and Durvillaea antarctica. Seaweed extracts in methanol and 70% acetone were performed to evaluate antioxidant and antidiabetic activities, whereas 60% methanol was used to measure anti-inflammatory and antimicrobial activities. Acetone extracts from D. antarctica had the highest total phenolic content and consequently exhibited the strongest antioxidant activity, while methanol extract of this seaweed presented the highest α-glucosidase inhibition (IC50= 0.004 mg mL-1). In the tests against E. coli and Penicillium sp., the extracts obtained from Ulva spp. were the most effective and exhibited the maximum anti-inflammatory effect against phorbol 12-myristate 13-acetate irritant agent (61.8% inhibition) in mice. Results indicated that all evaluated Chilean seaweed extracts are promising candidates for application in functional foods and in the pharmaceutical industry.

RESUMEN El objetivo de este estudio fue evaluar las actividades antioxidantes, antidiabéticas, antiinflamatorias y antimicrobianas de los extractos de tres algas marinas comestibles de las costas Chilenas (Pyropia orbicularis, Ulva spp. y Durvillaea antarctica). Se realizaron extractos de algas marinas en metanol y acetona al 70% para evaluar las actividades antioxidantes y antidiabéticas, mientras que el metanol al 60% se usó para actividades antiinflamatorias y antimicrobianas. Los extractos de acetona de D. antarctica tuvieron el mayor contenido de fenoles totales (TPC) y, en consecuencia, exhibieron la mayor actividad antioxidante, mientras que el extracto metanólico de estas algas presentó la mayor inhibición de la α-glucosidasa (IC50= 0,004 mg mL-1). En las pruebas contra E. coli y Penicillium sp., los extractos obtenidos de Ulva spp., actuaron como los más efectivos y exhibieron el máximo efecto antiinflamatorio contra el agente irritante de forbol 12-miristato 13-acetato (TPA) (inhibición del 61,8%) en ratones. Por lo tanto, los resultados indican que todos los extractos de algas chilenas evaluados pueden ser candidatos prometedores para su aplicación en alimentos funcionales y en las industrias farmacéuticas.

Encapsulación de extractos antioxidantes desde sub-productos agroindustriales: una revisión / Encapsulation of antioxidant extracts from agroindustrial by-products: a review

RESUMEN Actualmente se generan grandes cantidades de sub-productos agroindustriales como residuos, aun cuando pueden ser fuente importante de variados compuestos antioxidantes. Una de las formas de aprovechar esta funcionalidad es concentrar los antioxidantes mediante la elaboración de extractos, siendo las "extracciones verdes", que usan solventes como agua o etanol, que por ser más amigables con el medio ambiente y la salud humana, han sido las más estudiadas en los últimos años. Sin embargo, uno de los principales problemas de reutilizar este tipo de compuestos bioactivos es mantener su estabilidad, debido a que luego de ser extraídos desde su matriz biológica son muy sensibles a distintas condiciones medioambientales y de almacenamiento. Una tecnología que puede reducir la inestabilidad de los compuestos antioxidantes es la encapsulación, la cual también reduce las alteraciones organolépticas que se pudieran producir cuando son incorporados en alimentos. Según nuestro conocimiento no existen revisiones de encapsulación de extractos de sub-productos agroindustriales (en donde se puede encontrar una gran variedad de compuestos antioxidantes) y la información existente se basa en compuestos antioxidantes específicos encapsulados. Por tanto, el objetivo de esta revisión fue recopilar información actualizada respecto a la encapsulación de extractos antioxidantes obtenidos a partir de sub-productos agroindustriales vegetales y su incorporación como ingredientes en alimentos.

ABSTRACT Currently large quantities of agro-industrial by-products are generated as waste even when they can be used as important sources of various antioxidant compounds. One of the ways to take advantage of this functionality is to concentrate antioxidants via the preparation of extracts. Due to their lower impact on the environment and human health "green extractions" using solvents such as water or alcohol have been the most studied in recent years. However, one of the main problems in re-using these bioactive compounds is maintaining stability after being extracted from their biological matrix. Instability relates to different environmental and storage conditions. One technology that can reduce antioxidants instability is encapsulation, which also reduces organoleptic alterations that could occur when they are incorporated into food. To our knowledge there are no reviews of encapsulation of agroindustry by-product extracts (where a wide variety of antioxidant compounds can be found) and existing information is based on specific encapsulated antioxidant compounds. Therefore, the objective of this review was to gather up-to-date information regarding the encapsulation of antioxidant extracts obtained from vegetable agro-industrial by-products and their incorporation as ingredients in food.

Oligosacáridos y polisacáridos no digeribles: una fuente de salud para los adultos mayores / Non-digestible oligosaccharides and polysaccharides: a source of health for older people

RESUMEN Los adultos mayores son especialmente vulnerables a sufrir enfermedades asociadas al tracto gastrointestinal, ya que el envejecimiento conlleva naturalmente a un desbalance en la diversidad y cantidad de los microorganismos presentes en el intestino. Por ello, la suplementación de su dieta con oligosacáridos y polisacáridos no digestibles (OPND) ha cobrado gran relevancia científica. Esto, con el propósito de prevenir y revertir, en parte, los cambios negativos en la microbiota intestinal derivados del envejecimiento. Se ha observado que la suplementación de OPND en adultos mayores genera variados beneficios, entre los que destacan una mejora en el sistema inmune, una mayor absorción de calcio, reducción en la incidencia de alergias, reducción de la constipación y una disminución en los niveles de glicemia y colesterol sanguíneos. Debido a que, los efectos del consumo de OPND en adultos mayores han sido escasamente discutidos en la literatura científica en idioma castellano, el propósito de esta revisión es abordar el tema haciendo énfasis en la realidad chilena y latinoamericana. Ello, con miras a fomentar la incorporación de OPND en alimentos y programas de alimentación dirigidos específicamente a personas de la tercera edad.

ABSTRACT Since aging naturally leads to an imbalance in the diversity and quantity of microorganisms present in the intestine, older people are particularly vulnerable to diseases associated with the gastrointestinal tract. Thus, supplementing the diet of elderly persons with non-digestible oligosaccharides and polysaccharides (OPND) has gained scientific relevance. Supplementation aims to prevent and (partially) revert the negative changes in intestinal microbiota due to aging. It has been observed that OPND supplementation in older adults provides several benefits, including an improvement in the immune system, increased calcium absorption, a reduction in the incidence of allergies, a reduction in constipation and a decrease in blood levels of cholesterol and glucose. Because the effects of OPND supplementation in older adults has been scarcely discussed in the scientific literature in the Spanish language, the purpose of this review is to address the issue with emphasis on the Chilean and Latin-American reality. The article promotes the incorporation of OPND in processed food and feeding programs specifically designed for older people in Latin America.
