ABSTRACT

@#A review conducted on the regulatory status of bioactive non-nutritional food components in foods and beverages in eight Southeast Asian countries indicates these components have been recognised for their health benefits. Indonesia and Malaysia have promulgated specific regulations allowing the addition of these bioactive components in foods and beverages, provided a list of the permitted components that may be used, and clear process for the industry to apply for new components. Both countries also have separate regulations that govern the making of function claims which refer to the beneficial physiological or health effects brought about by such bioactive components. The other six countries do not have a specific regulation governing the use of these bioactive components. However, these countries also permit the making of similar function claims, provided they are scientifically substantiated, preferably human clinical trials. Each country has slightly different requirements and process in place for reviewing applications for claims. All countries, except Myanmar, also allow the sale and marketing of foods containing probiotics, another functional food component. Indonesia, Malaysia, Philippines and Thailand have promulgated specific probiotic regulations and, except for Indonesia, have published permitted list of probiotics. All seven countries have provisions for the industry to apply for the use of new probiotics. Malaysia, Philippines, Singapore and Thailand permit the use of a pre-approved generic function claims related to probiotics. The sharing of experiences in regulatory approaches would be beneficial to the advancement of scientific and regulatory development of bioactive non-nutritional food components in the region and would benefit all stakeholders.

ABSTRACT

Resumen Las cabras habitan regiones áridas como resultado de su adaptación a condiciones extremas. La selección de la dieta es una de las estrategias conductuales que les han permitido evitar deficiencias nutricionales o intoxicaciones aun en condiciones de baja disponibilidad de alimento. Así mismo, el ramoneo, como conducta ingestiva de la especie, les permite seleccionar y obtener plantas con adecuados valores de proteína cruda que favorezcan su desarrollo y supervivencia. También, las cabras se adaptan a las características químicas de las plantas, las cuales desarrollan compuestos bioactivos para evitar ser consumidas. Estos metabolitos secundarios pueden tener efectos antinutricionales y tóxicos así como medicinales o curativos, dependiendo del consumo que tenga el animal. El objetivo de este trabajo fue revisar la selección y hábitos de las cabras en el consumo de plantas nativas, para determinar cómo favorecen la supervivencia y productividad de la especie, bajo las condiciones de adversidad ambiental que caracterizan a las regiones áridas. Dicho conocimiento permitirá establecer estrategias para el manejo adecuado del agostadero y conocer el efecto que los compuestos del metabolismo secundario de las plantas puedan tener en los procesos reproductivos, nutricionales, sanitarios, así como en los productos derivados de la leche o carne de estos animales.


Abstract Goats dwell arid regions as a result of their adaptation to extreme conditions. Diet selection is one of the behavioral strategies that has allowed them to avoid nutritional deficiencies or poisonings, even under conditions of low food availability. Likewise, browsing as an ingestive behavior of the species allows them to select and obtain plants with adequate crude protein values, which favor their development and survival. Also, goats adapt to the chemical characteristics of plants, which develop bioactive compounds to avoid being consumed. These secondary metabolites can have antinutritional and toxic effects, as well as medicinal or curative effects, depending on the consumption that the animal has. The objective of this work was to review the selection and habits of goats in the consumption of native plants, to determine how they favor the survival and productivity of the species under the conditions of environmental adversity that characterize arid regions. This knowledge will allow to establish strategies for the proper management of the rangeland and to know the effect that the compounds of the secondary metabolism of the plants may have on the reproductive, nutritional, and health processes, as well as on the products derived from the milk or meat of these animals.

ABSTRACT

This study is to clarify the composition and content differences of water-soluble nutrients in Lycium barbarum leaves(LBLs) from different areas. The total polysaccharides, free monosaccharides and oligosaccharides, nucleosides and amino acids in 35 batches of LBLs were analyzed with use of spectrophotometry, HPLC-ELSD and UPLC-MS/MS. The results showed that LBLs contained abundant polysaccharides, fructose, glucose, sucrose and maltose, with an average contents of 39.07, 12.69, 8.99, 17.44, 8.32 mg·g~(-1), respectively. Besides, eight nucleosides and twelve amino acids were detected in LBLs, and their average total contents were 54.95, 336.9 μg·g~(-1). Principal component analysis(PCA) and partial least squares discrimination analysis(PLS-DA) of carbohydrate, nucleoside and amino acid showed that the water-soluble nutrients of the samples from Qinghai Province were significantly different from those from other areas mainly in asparagine, proline, glutamine, sucrose, adenine and guanosine. In this study, the compositions and contents of water-soluble nutrients in LBLs were preliminarily clarified, which provided basis for further development and utilization of LBLs resoures.

ABSTRACT

La alimentación influye en la mejora de la sintomatología de cualquier enfermedad, incluida la esclerosis múltiple (EM),la cual, se caracteriza por un proceso inflamatorio crónico, autoinmune del sistema nervioso central generando situaciones como inflamación, alteraciones; digestivas y mentales, discapacidad, y fatiga. El propósito de la presente revisión fue identificar la evidencia científica sobre los aspectos nutricionales que mejoran la progresión de EM. La metodología consistió en la búsqueda de literatura, en bases de datos electrónicas, referente a nutrición y esclerosis múltiple, principalmente entre los años 2015-2020. Entre los resultados de los aspectos nutricionales que mostraron eficacia en mejorar la progresión de EM, se encuentran el zinc, vitamina D, fibra, probióticos, aceite de pescado y de oliva, cacao, cúrcuma, y salmón. Existen evidencias del papel inmunomodulador del Zn y de la vitamina D en la inhibición de la producción de citocinas proinflamatorias. Niveles bajos de ambos componentes se asocian con mayor riesgo de padecer EM. Otros componentes de interés nutricional son la fibra y probióticos; producen ácidos grasos de cadena corta, con propiedades antiinflamatorias. La primera se conoce por su papel en la motilidad gastrointestinal y los segundos por su acción celular y molecular en procesos inflamatorios, y modulación del microbioma, por mencionar algunos. Los aspectos nutricionales antes mencionados pueden contribuir a modular la inflamación y mejorar la fatiga. Finalmente, este documento genera un panorama importante para continuar con la investigación referente a la influencia de la alimentación en pacientes con EM(AU)


Diet influences the improvement of the symptoms of any disease, including multiple sclerosis (MS), which is characterized by a chronic, autoimmune inflammatory process of the central nervous system generating situations such as inflammation, mental and digestive alterations, disability and fatigue. The aim of this review was to identify the scientific evidence on the nutritional aspects that improve the progression of MS. The methodology consisted of searching literature, in electronic databases, referring to nutrition and multiple sclerosis, mainly between the years 2015-2020. The results of the nutritional aspects that showed effectiveness in improving the progression of MS, are zinc, vitamin D, fiber, probiotics, fish oil and olive oil, cocoa, turmeric and salmon. There is evidence of the immunomodulatory role of Zn and vitamin D in inhibiting the production of proinflammatory citokines. Low levels of both components are associated with an increased risk of MS. Other components of nutritional interest are fiber and probiotics; they produce short chain fatty acids, with anti-inflammatory properties. The first is known for its role in gastrointestinal motility and the second one for its cellular and molecular actions in inflammatory processes and the microbiome modulation, to name a few. The nutrition aspects mentioned above, can contribute to modulate inflammation and improve fatigue. Finally, this paper creates an important perspective to continue the investigation concerning the influence of diet in MS patients(AU)

ABSTRACT

Using split plot design, a pot experiment with sand culture was conducted to investigate the effects ofnitrogen and sulfur combined application on nutritional components and active component of Isatis indigotica at seedling stage under different N (5,15,25 mmol·L⁻¹)and S(0.00,1.25,2.50,5.00,7.50 mmol·L⁻¹) levels. The results showed thatthe two elements had obvious effects and the leaf and root dry weights of I. indigotica seedlings increased greatly at N₂ level. Under the same nitrogen concentration, the leaf and root dry weights increased firstly and decreased with the rising of sulfur concentrations in which S₂ was conducive to the growth and biomass accumulation. Soluble sugar, soluble protein, soluble amino acids contents were the highest in N₁, N₂ and N₃ treatments, respectively. The influence of sulfur concentrations on nutritional components was same as biomass, but the peak of different nutritional components was diversity in different nitrogen levels. The effects on secondary metabolites (total flavones, indigo, indriubin, epigotrin contents) were not obvious significantly, in which these indexes by N₁S₃,N₁S₂,N₃S₀,N₃S₁were the highest, respectively. In conclusion, the combination of nitrogen and sulfur of N₂S₂(N 15 mmol·L⁻¹ and S 2.5 mmol·L⁻¹) was beneficial to the growth and secondary metabolites accumulation of I. indigotica. These results could provide a theoretical basis for rational fertilization and cultivation of I. indigotica seedling.

ABSTRACT

Objective: To study the morphologic differences and nutritional components of the natural and broken Masson pine pollen. Methods: Pure pollen was collected from Masson pine (Pinus Massoniana Lamb) and the dry pollen was broken by high speed low temperature air flow technique. Their morphologic changes were observed under scan electronic microscopy. The nutritional components of pollen were analyzed.Results: The pollen particle consists of two air bags and one main part, like a mushroom cap. The main morphologic change of broken pollen was that the air bags were separated from pollen particles, and the main part of pollen particles became enriched. The physical characteristics of pollen were changed in container and its fluidity was lost. The broken pollen had very strong adhesiveness. So it could not fly like natural pollen. In broken pollen, the rough fiber, cellulose and semi cellulose contents decreased significantly. Total energy, total lipid, and starch contents increased remarkably. The water soluble and fat soluble components also increased greatly. The total amino acids content of broken pollen was higher than natural pollen except Cys, Arg and Met, and free amino acids were also higher except Cys, Gly and Met. In broken pollen, the amount of lipids extracted by ether increased sharply, nearly 7 times more than natural pollen.Conclusion: It is considered that some nutritional components of natural pollen can be released after broken. Because most of the lipids in pollen are easily oxidized, broken pollen can not be stored for long time.
