ABSTRACT

Resumen La actividad cervecera en la Patagonia andina argentina tiene un rol muy importante en la economía de la región; una de las problemáticas que enfrenta, en términos de calidad, son las contaminaciones microbianas. La presencia de bacterias y levaduras contaminantes en la cerveza produce cambios microbiológicos, físicos y químicos, que impactan en sus atributos sensoriales. No obstante, pocas cervecerías establecen criterios y políticas que garanticen la calidad microbiológica de sus productos. El propósito de este trabajo fue estudiar por primera vez la incidencia de contaminantes microbianos en cervezas artesanales embotelladas producidas en la Patagonia andina argentina, además de identificar los principales microorganismos involucrados y determinar posibles relaciones entre los eventos de contaminación y variables fisicoquímicas de la cerveza. Para ello se analizaron 75 cervezas provenientes de 37 cervecerías de 12 localidades andinas. El 69,3% de las muestras analizadas evidenció crecimiento de microorganismos en los medios de cultivo empleados para la detección de contaminantes cerveceros. La bacteria Levilactobacillus brevis y levaduras del género Saccharomyces fueron los principales contaminantes identificados. Se comprobó que las contaminaciones microbianas impactaron sobre el perfil sensorial de la cerveza y que el cambio de pH fue un indicador de contaminación por bacterias lácticas. De cada 10 fábricas estudiadas, 8 presentaron problemas de contaminación, lo que pone en evidencia la necesidad de diseñar estrategias de prevención y control de contaminaciones en microcervecerías.


Abstract The brewing activity in Andean Patagonia plays a very important role in the region's economy, being microbial contamination one of the main problems in terms of quality. The presence of contaminant bacteria and wild yeasts in beer generate microbiological, physical and chemical changes that impact on its sensory attributes. However, few breweries establish criteria and policies to guarantee the quality of their products in a microbiological sense. The purpose of this work was to study for the first time the incidence of microbial contaminants in bottled craft beers from Andean Patagonia, identify the main microorganisms involved and establish relationships between contamination and the physicochemical variables of beer. We analyzed 75 beers from 37 breweries from 12 different Patagonian cities. Our results showed that 69.3% of the analyzed beer exhibited contaminant microorganism growth. Bacteria Levilactobacillus brevis and wild yeasts of Saccharomyces were the main microorganisms responsible for these contaminations. In addition, we found that microbial contamination had an impact on beer sensory profile and also that pH was correlated with the presence of lactic acid bacteria in beer, being an indicator of contamination for these bacteria. In conclusion, we observed that 8 out of 10 breweries studied showed contamination problems, highlighting the need to design prevention and control strategies in microbreweries.

ABSTRACT

Introduction: There is currently a great controversy about the lack of definition regarding the concept of moderate consumption of alcoholic beverages from the point of view of health, since, in turn, it should be a socially accepted consumption. Although still there is not a global agreement about the definition of "moderate consumption", it is considered as such the amount below 10-12 g alcohol/day for women and no more than 20-24g alcohol/day for men. These differences are because that women are not capable as men to metabolise alcohol. According to the scientific evidence, moderate consumption of beer seems to be accepted to maintain an adequate quality of the diet, as it provides vitamins B (vitamin B6, B12 and folates) and minerals (magnesium) among other nutrients, as well as poliphenols and complex carbohydrates. In terms of health, a moderate beer consumption may play a protective role at cardiovascular levels, associated with an enhanced lipid profile. It should be highlighted the possible beneficial effects of a moderate consumption of fermented beverages (such as beer) is associated with other factors, such as gender, age, as well as the pattern of consumption throughout life.


Introducción: Actualmente existe una gran controversia relativa a la falta de definición respecto a lo que se considera un consumo moderado de bebidas alcohólicas desde el punto de vista de la salud, ya que, a su vez, debería ser un consumo socialmente aceptado. Aunque no existe una definición universalmente consensuada de consumo moderado, se considera como tal la cantidad por debajo de 10-12 g de alcohol al día para mujeres y de no más de 20-24 g alcohol al día para hombres. Estas diferencias se deben a la menor capacidad de las mujeres para metabolizar el alcohol. De acuerdo con la evidencia científica, parece aceptarse que el consumo moderado de cerveza puede colaborar en mantener una adecuada calidad de la dieta, ya que aporta vitaminas del complejo B (vitamina B6, B12 y folatos) y minerales (magnesio), entre otros nutrientes, así como polifenoles y carbohidratos complejos. En referencia a la salud, se ha atribuido a la cerveza un papel protector a nivel cardiovascular, asociado a un mejor perfil lipídico. Todo ello podría indicar un papel protector a nivel cardiovascular. También es importante señalar que el posible efecto beneficioso de un consumo moderado de bebidas fermentadas (como la cerveza) está asociado a otros factores como el sexo, la edad y el patrón de consumo a lo largo de la vida.

ABSTRACT

Yeasts play a crucial role in brewing. During fermentation, besides ethanol and carbon dioxide, yeasts produce a considerable number of organic compounds, which are essential for beer flavor. In particular, Saccharomyces cerevisiae and Saccharomyces pastorianus are traditionally used in the production of ale and lager beers, respectively. Nowadays, the continuous growth of the craft beer market motivates the production of differential and innovative beers; leading specialists and brewers focus on non-conventional yeasts as tools for new product development. In this work, we describe the potential application of non-conventional yeast species such as those of the genera Brettanomyces, Torulaspora, Lachancea, Wickerhamomyces, Pichia and Mrakia in the craft brewing industry, as well as non-traditional brewing yeasts of the Saccharomyces genus. Furthermore, the fermentation conditions of these non-conventional yeasts are discussed, along with their abilities to assimilate and metabolize diverse wort components providing differential characteristics to the final product. In summary, we present a comprehensive review of the state-of-the-art of non-conventional yeasts, which is highly relevant for their application in the production of novel craft beers including flavored beers, non-alcoholic beers, low-calorie beers and functional beers.

ABSTRACT

INTRODUCTION: A large evidence-based reports a J-shaped association among moderate alcohol consumption and cardiovascular health. Low-moderate alcohol intake has been related to lower all-cause mortality (20%) and ischemic heart events (40%) compared to abstainers. The dose that is allegedly beneficial varies between 10-20 gr/day for women and men respectively. Moreover, the drinking pattern seems to be significant in order to get healthy effects. Moderate alcohol consumption hinders atherogenesis by several mechanisms mainly improving lipid profile and reducing thrombogenesis. Nevertheless, it is still unclear whether high-polyphenol alcoholic beverages, such as wine and beer, confer a greater cardiovascular protection than spirits, which have much less polyphenol content.


INTRODUCCIÓN: Existe mucha evidencia que sugiere una relación en J entre el consumo moderado de alcohol y la salud cardiovascular. Se ha referido una reducción de alrededor del 20% en la mortalidad y de hasta el 40% en la cardiopatía isquémica en los bebedores moderados respecto a los abstemios absolutos. Las dosis consideradas saludables oscilan entre 10 y 20 g/día para mujeres y hombres, respectivamente, y parece que el patrón de bebida es igualmente relevante para obtener ese efecto saludable. Múltiples son los mecanismos que pueden explicar el retraso en la aterogénesis inducido por el consumo saludable de alcohol, pero probablemente los efectos sobre los lípidos y las plaquetas son los más importantes. Sin embargo, se mantiene la controversia sobre si las bebidas alcohólicas fermentadas con alto contenido en polifenoles como cerveza o vino tienen un mayor efecto de protección cardiovascular que los licores que no contienen apenas polifenoles.

ABSTRACT

ABSTRACT Objective: Despite the presence of multitude of synthetic drugs against fever and inflammation, none has been proven entirely safe. In contrast, the accepted safety of plant derived natural products is inspiring the world. Based on this fact as well as in view of the diversified activities reported from the genus Gymnosporia, the present study was designed to evaluate the antipyretic and anti-inflammatory activity of Gymnosporia royleana (G royleana). Methods: The methanolic extract of the aerial parts of G royleana was screened for in-vivo antipyretic activity using the brewer's yeast-induced pyrexia mice model and for anti-inflammatory activity using the carrageenan-induced paw oedema and xylene-induced ear oedema mice model. Results: In the antipyretic assay, G royleana extract showed considerable antipyretic activity in a dose dependent fashion. Statistically significant antipyretic effects (p < 0.05) were observed at the end of the second hour of administration for all doses of extract and remained significant until the end of the experiment. The plant extract also displayed promising anti-inflammatory activity, in a dose dependent fashion, in both models of inflammation ie carrageenan- and xylene-induced oedema models, when compared to the controls. In the carrageenan-induced oedema model, significant effects (p < 0.01) were observed for 300 and 600 mg/kg doses after 60 minutes of xylene administration (ie 55.51% and 65.88% inhibition of oedema, respectively). Conclusion: The study provided evidence supporting the antipyretic and anti-inflammatory activity of the G royleana methanolic extract.


RESUMEN Objetivo: A pesar de la presencia de multitud de fármacos sintéticos en el arsenal contra la fiebre y la inflamación, ninguno ha dado pruebas de ser completamente seguro. En contraste con ello, la seguridad aceptada de los productos naturales derivados de las plantas inspira al mundo. Sobre la base de este hecho, así como en vista de las actividades diversificadas que se reportan con respecto al género Gymnosporia, el presente estudio se diseñó con el objeto de evaluar el potencial antipirético y antiinflamatorio de Gymnosporia royleana (G royleana). Métodos: El extracto de metanol de las partes aéreas de G royleana fue tamizado en busca de actividad antipirética in vivo, utilizando el modelo de pirexia inducida por levadura de cerveza en ratones, y de actividad antiinflamatoria utilizando modelos de ratones con oedema de las patas inducido mediante carragenina, y oedema de las orejas inducido mediante xileno. Resultados: En el ensayo antipirético, el extracto de G royleana mostró una actividad antipirética considerable en forma dependiente de la dosis. Se observó un efecto antipirético estadísticamente significativo (p < 0.05) en el transcurso de la segunda hora de administración para todas las dosis de extracto y se mantuvo significativo hasta el final del experimento. El extracto de la planta también mostró una actividad antiinflamatoria prometedora, de una manera dependiente de la dosis, en ambos modelos de inflamación, es decir, modelos de oedema inducido por carragenina y xileno, en comparación con el control. En el modelo de oedema inducido por carragenina, se observó un efecto significativo (p < 0.01) para dosis de 300 y 600 mg / kg después de 60 minutos de administración de xileno (es decir, 55.51% y 65.88% de inhibición del oedema, respectivamente). Conclusión: El estudio proporcionó pruebas suficientes sobre el potencial antipirético y antiinflamatorio del extracto de G royleana.

ABSTRACT

Obesity is a very prevalent disease with multiple chronic complications that decrease or disappear after a small (5-10%) but maintained weight loss. Nevertheless, maintaining weight loss after the treatment is very difficult and it involves one of the biggest challenges to control this epidemic. Although the reasons that contribute to regain the lost weight are diverse and related to the biological response to caloric restriction and the lack of adherence to treatment, up to 20% of the patients are able to keep it off. The keys to success, involve the maintenance of healthy habits, exercise and a reasonable daily calorie intake to allow a normal way of life, without sacrificing the social life. At this point, learning to distinguish food and drink options in a society where social life often revolves around the table is very important. We review the keys to keep the weight off after a diet as well as the role of fermented beverages such as beer, in this process. In conclusion, maintenance the weight loss is harder than losing it. The mild-to-moderate consumption of fermented beverages such as beer is not associated with weight increase.


La obesidad es una enfermedad muy prevalente con múltiples complicaciones crónicas que se reducen o desaparecen tras pérdidas pequeñas (5-10%) pero mantenidas de peso. Sin embargo, mantener la pérdida de peso tras el tratamiento es muy difícil, siendo uno de los mayores retos en el control de esta enfermedad. Aunque las razones que contribuyen a recuperar el peso perdido son de diversa índole, relacionadas con la respuesta biológica a la restricción calórica y con la pérdida de adherencia al tratamiento, hasta un 20% de los pacientes son capaces de mantenerlo. Las claves del éxito están relacionadas con el mantenimiento de los hábitos de vida saludable, el ejercicio físico y una ingesta calórica razonable que permita realizar una vida normal, sin pérdida de vida social. En este sentido, aprender a distinguir las opciones de comida y bebida en una sociedad donde la vida social gira en torno a la mesa en muchas ocasiones es muy importante. Revisamos en este artículo las claves para mantener el peso tras una dieta, así como el papel de las bebidas fermentadas, en especial, la cerveza, en este proceso. En conclusión, mantener el peso perdido es más difícil que perderlo. El consumo leve-moderado de bebidas fermentadas como la cerveza no se asocia con incremento del peso.

ABSTRACT

INTRODUCTION: Beer is a beverage that has been usually included in our habitual diet from immemorial time. However, beer consumption depends on food habits and lifestyle in different populations. In Mediterranean countries, fermented beverages like beer, takes up a key space in the Mediterranean diet that has been declared in 2010 as Cultural Immaterial World Heritage by UNESCO. OBJECTIVES: The positioning where the Spanish Society of Primary Care Medicine and the Beer and Health Information Centre have conjointly worked on has the following beer consumption-related aims: a) to update its knowledge based on the scientific evidence; b) to evaluate the possibility to include it within a healthy diet for healthy adults; c) to inform health professionals and the general population about its possible health benefits. METHODOLOGY: A panel of experts, represented by clinicians and researchers in the field of nutrition held a meeting with the purpose to review the scientific literature related to the effects of the moderate consumption of fermented beverages, particularly beer, and to reach a consensus on the results, conclusions and recommendations suggested and established by other experts at an international level. RESULTS: The current scientific evidence reflects that moderate consumption of beer does not affect anthropometry related variables. Although energy supply from beer is very low, its nutrients and bioactive compound contents are interesting, since its potential antioxidant effect together with the fact that anti-carcinogenic, anti-inflammatory and anti-viral effects have been demonstrated, as well as its beneficial effect on cardiovascular health, leading to a greater protection than even in the abstemious population. CONCLUSIONS: In view of the results obtained from the literature consulted by the expert panel, we can conclude that the moderate consumption of beer can be considered within a healthy diet. Nevertheless, the general recommendation is addressed only to healthy adults, never to children, adolescents or pregnant women. In the case of elderly people, any beverage containing alcohol should not be recommended for those who are treated with drugs in order to avoid possible interactions with alcohol consumption.

ABSTRACT

Este trabalho analisa as representações de masculinidades na propaganda de cervejas, investigando uma abordagem em apresentar o homem como consumidor em potencial: ratificada por uma masculinidade hegemônica; e a mulher objetificada: como figuração do prazer e/ou da representação feminina de dona de casa, marcada no ambiente doméstico; configurando em uma associação de assimetria de poder. Para tanto, são discutidos como o papel da masculinidade vem sendo construídos, significados e ressignificados na propaganda brasileira de cervejas. A análise baseia-se em observações realizadas em anúncios vinculados na TV aberta, além de peças publicitárias colhidas no ciberespaço; de cervejas nacionais e internacionais, a exemplo da "Skol", "Nova Schin", "Heineken", entre outras. Como resultado, percebe-se que os anúncios de cervejas, atualmente, associam os consumidores de cerveja ao gênero masculino e para isso realizam anúncios valorizando o homem heterossexual, colocando - o como grande protagonista desses contextos.(AU)


This work examines the representations of masculinity in advertising beer, investigating an approach in presenting the man as a potential consumer: ratified by a hegemonic masculinity, and the objectified woman: as pleasure figuration and/or female representation of housewife, marked in the household; setting in a pool of power asymmetry. To this end, we discuss how masculinity role are being built, and resignified meanings in Brazilian advertising of beers. The analysis is based on observations made in open linked ads on TV, and advertising harvested in cyberspace, national and international beers, such as the "Skol", "Nova Schin", "Heineken", among others. As a result, one realizes that the listings of beers currently associate beer drinkers to males and to realize that ads valuing heterosexual man, putting - like the great protagonist of these contexts.(AU)


En este trabajo se ha analizado las representaciones de masculinidades en el anuncio de cerveza, investigando un enfoque en la presentación del hombre como consumidor potencial: ratificado por una masculinidad hegemônica; y la mujer objetivada como figuración del placer y/o de la representación femenino de ama de casa, marcada en el hogar; resultando en la creación de una combinación de asimetría de poder. Para eso, se discutió como el papel de la masculinidad ha sido construído, significado y reformulado en los anuncios de cerveza em Brasil. El análisis esta basado en observaciones realizadas en anuncios de la televisón abierta, además piezas de publicidad logradas en el ciberespacio; de cervezas nacionales y internacionales, por ejemplo "Skol", "Nova Schin", "Heineken", entre otras. Como resultado, se ha notado que los anuncios de cervezas, hoy en dia, asocían los bebedores de cerveza a los varones y para llevar a cabo hay la valorización del hombre heterossexual como el gran protagonista de este contexto.(AU)

ABSTRACT

Different natural antimicrobials affected viability of bacterial contaminants isolated at critical steps during a beer production process. In the presence of 1 mg/ml chitosan and 0.3 mg/ml hops, the viability of Escherichia coli in an all malt barley extract wort could be reduced to 0.7 and 0.1% respectively after 2 hour- incubation at 4 °C. The addition of 0.0002 mg/ml nisin, 0.1 mg/ml chitosan or 0.3 mg/ml hops, selectively inhibited growth of Pediococcus sp. in more than 10,000 times with respect to brewing yeast in a mixed culture. In the presence of 0.1mg ml chitosan in beer, no viable cells of the thermoresistant strain Bacillus megaterium were detected. Nisin, chitosan and hops increased microbiological stability during storage of a local commercial beer inoculated with Lactobacillus plantarum or Pediococcus sp. isolated from wort. Pulsed Electric Field (PEF) (8 kV/cm, 3 pulses) application enhanced antibacterial activity of nisin and hops but not that of chitosan. The results herein obtained suggest that the use of these antimicrobial compounds in isolation or in combination with PEF would be effective to control bacterial contamination during beer production and storage.


Diferentes antimicrobianos naturales disminuyeron la viabilidad de bacterias contaminantes aisladas en etapas críticas del proceso de producción de cerveza. En un extracto de malta, el agregado de 1 mg/ml de quitosano y de 0,3 mg ml de lúpulo permitió reducir la viabilidad de Escherichia coli a 0,7 y 0,1%, respectivamente, al cabo de 2 horas de incubación a 4 °C. El agregado de 0,0002 mg/ml de nisina, 0,1 mg/ml de quitosano o de 0,3 mg/ml de lúpulo inhibió selectivamente (10.000 veces más) el crecimiento de Pediococcus sp. respecto de la levadura de cerveza en un cultivo mixto. El agregado de 0,1 mg/ml de quitosano permitió disminuir la viabilidad de una cepa bacteriana termorresistente, Bacillus megaterium, hasta niveles no detectables. Por otra parte, el agregado de nisina, quitosano y lúpulo aumentó la estabilidad microbiológica durante el almacenamiento de cervezas inoculadas con Lactobacillus plantarum y Pediococcus sp. aislados de mosto de cerveza. La aplicación de campos eléctricos pulsantes (CEP) (3 pulsos de 8kV/cm) aumentó el efecto antimicrobiano de la nisina y del lúpulo, pero no el del quitosano. Los resultados obtenidos indicarían que el uso de antimicrobianos naturales en forma individual o en combinación con CEP puede constituir un procedimiento efectivo para el control de la contaminación bacteriana durante el proceso de elaboración y almacenamiento de la cerveza.
