Contenido y caracterización reológica de los polisacáridos estructurales de nopalitos (Opuntia spp.) en un gradiente de domesticación.
Provedor de dados: 32
Autores: López Palacios, Cristian.
Evidencias diversas indican que la domesticación del género Opuntia comenzó con la selección de variantes de O. streptacantha, seguida de O. hyptiacantha y O. megacantha y se centró en O. albicarpa y O. ficus indica. Las causas por las cuales se domesticó Opuntia fueron por sus frutos y nopalitos. Los polisacáridos más abundantes en los nopalitos son del tipo estructural. La hipótesis que se plantea es que los polisacáridos muestran un gradiente de concentración y sus propiedades reológicas han sido modificadas en función del grado de domesticación de Opuntia. Los polisacáridos estructurales fueron extraídos de cladodios jóvenes de 14 variantes pertenecientes a especies representantes del gradiente de domesticación (O. streptacantha, O. hyptiacantha, O....

Provedor de dados: 32
Autores: Calvo Arriaga, Ayne Oliva.
La diabetes mellitus afecta a más de 220 millones de personas en el mundo y es una de las causas principales de muerte. Existe evidencia de que los frutos ácidos de Opuntia joconostle y O. matudae, denominados xoconostle, disminuyen la glucemia e incrementan la concentración sérica de insulina en individuos diabéticos. El presente estudio fue propuesto para dilucidar si esos efectos y otros relacionados con el metabolismo energético, como la disminución de colesterol y triglicéridos en la sangre, se deben a los mucílagos, pectinas o hemicelulosas de xoconostle, a todos ellos o a ninguno de ellos. La hipótesis es que estos polisacáridos ocasionan disminución de las concentraciones séricas de glucosa, colesterol y triglicéridos, e incremento de la secreción...

B-type oligomeric procyanidins in apples constitute an important source of polyphenols in the human diet. Their role in health is not known, although it is suggested that they generate beneficial bioactive compounds upon metabolization by the gut microbiota. During apple processing, procyanidins interact with cell-wall polysaccharides and form stable complexes. These interactions need to be taken into consideration in order to better assess the biological effects of fruit constituents. Our objectives were to evaluate the impact of these interactions on the microbial metabolization of cell walls and procyanidins, and to investigate the potential anti-inflammatory activity of the resulting metabolome, in addition to analyzing the taxonomical changes which...

Provedor de dados: 31
Autores: Duarte,   Patricia Rayas; Romero Baranzini,   Ana Lourdes.
Dietary fiber has many health benefits, including positive impact on numerous chronic and life threatening diseases. Whole grain foods, legumes, fruits and vegetables are important sources of dietary fiber. In this article, the definitions of soluble and insoluble fiber, their mechanism of action and impact on health are discussed. Further, the characteristics and advantages of resistant starch, a high fiber product used by the food industry are outlined. There is a Dietary Reference Intake (DRI) for fiber in place for adults and children; it is recommended to cover that amount with natural food sources rather than in form of capsules. However, there are also natural high fiber supplements on the market; one of these food sources is Plantago psyllium,...

Dietary fiber is an important component, which has a direct effect on intake, digestion, and absorption of nutrients; and also alters intestinal microbiota and morphology according to solubility. One digestibility trial and one performance experiment were performed to evaluate the effects of sources of fiber in diets for 21 day weaned piglets. The experimental diets used in both trials consisted of a control diet and diets with purified cellulose, soybean hulls or citrus pulp as a main source of dietary fiber. To evaluate the digestibility of nutrients (Assay 1), the total feces and urine collection method was used. The fiber sources did not affect nutrient digestibility, except for soluble fiber, which increased with the inclusion of citrus (Citrus...

Digestive and functional properties of a partially hydrolyzed cassava solid waste with high insoluble fiber concentration
Provedor de dados: 63
Autores: Raupp,Dorivaldo da Silva; Rosa,Danielle Amorim; Marques,Silvia Helena de Paula; Banzatto,David Ariovaldo.
Starch factories generate large amounts of cassava solid waste. A small amount is utilized for animal feed but most of it is discharged with deleterious effects to the envirounment. A edible food with a high content of insoluble dietary fiber (60.9%), named "partially hidrolyzed cassava waste" (PHCW), was prepared from industrial cassava solid waste by an enzymatic process. PHCW or wheat bran (WB) were fed to model rats and both promoted digestive function effects, but PHCW produced the greatest effect. The insoluble fiber constituent from PHCW (and not the soluble fiber), promoted the greatest fecal bulking, fecal weight and defecation frequency in rats, as compared to WB. Such results indicate that the partially hydrolyzed cassava waste presents...

Effect of treatment with alkaline hydrogen peroxide associated with extrusion on color and hydration properties of oat hulls
Provedor de dados: 52
Autores: Galdeano,Melicia Cintia; Grossmann,Maria Victória Eiras.
An incomplete factorial design with three independent variables at three levels of variation was used to evaluate the effect of the treatment with alkaline hydrogen peroxide concomitant with extrusion on some properties of oat hulls. The independent variables were hydrogen peroxide level, feed moisture and extrusion temperature. The dependent variables were water retention capacity (WRC), swollen volume (SV) and color. The analysis of variance showed that temperature was the most important variable for the hydration properties. The highest values of WRC and SV were obtained when oat hulls were processed in the condition of 7% hydrogen peroxide, 32% feed moisture and 90ºC extrusion temperature. Modified hulls had a WRC 70% higher and SV 55% higher than the...
