Influence of dietary polyphenols on carbohydrate intestinal digestion and absorption
… specific polyphenolics to inhibit carbohydrate digestion (amylase and glucosidase) and (2) polyphenolic inhibition of intestinal glucose transport. While the high potential of these activities is evident, little is actually known regarding the extent to which these benefits are extendable to the …

Determination of honey varietal’s impact on Bifidobacterium animalis ssp lactis survivability in commercial yogurt through simulated in vitro digestion
… low-fat commercial yogurt through in vitro gastrointestinal digestion. Phase 1 tested four honey varietals (alfalfa, buckwheat, clover, and orange) at a final concentration of 20% weight by weight (w/w) in yogurt containing B. animalis. Yogurt samples started with an average of 8.6 log CFU/g per …

Formulation and application of alginate-based and soy protein isolate-stabilized emulsion gels
… modulus and shrinkage during simulated gastric digestion and delayed the release of lycopene from emulsion gel beads during intestinal digestion. The pH of emulsions can also influence the gelation mechanism and properties of emulsion gel beads. Emulsion gel beads at pH 3.0 showed lower …

Factors Affecting Viscosity of Select Dietary Fibers, Complete Food Matrices, and Canine Ileal Digesta
… of dietary factors on viscosity of gastrointestinal tract contents. In addition, a standardized method of gastrointestinal tract viscosity measurement has not been established. In Study 1, fibers were subjected to a two-stage in vitro gastric and small intestinal simulation model. …

VALORIZATION OF CHESTNUT BY-PRODUCT FOR GASTROINTESTINAL HEALTH
… factor (HIF-1α), as a potential stabilizer of intestinal barrier integrity. Therefore, the main objective of this PhD work includes a qualitative and quantitative phytochemical characterization of several chestnut by-products (bud, spiny bur, wood, pericarp and episperm), together with the …

Invasive SIlver Carp (Hypophthalmichthys molitrix) Protein Hydrolysates- A Potential Source of Natural Antioxidant
… (3) to determine the effect of simulated gastro intestinal digestion of SPH on its cell based antioxidant activity.</p> <p>The results showed that most of the SPH samples displayed higher or comparable antioxidant capacity than commercial antioxidants (BHA, BHT and α tocopherol). Further, the …

Distribution and Relative Abundance of Nutrient Transporter mRNA in the Gastrointestinal Tract of Black Bears
… abundant or available. The end-products of intestinal digestion are absorbed by the body through the action of transporter proteins expressed on the brushborder membrane of small intestinal epithelial cells. The goal of this study was to increase the understanding of the physiological …

Use of Newly Developed Blended Feed Supplement on Rumen Parameters and Milk Fat in Dairy Cows
… in situ protein to energy synchronization, intestinal digestion, and nutrient supply using NRC and DVE/OEB systems were also studied. The BFS demonstrated the highest (P < 0.05) levels of rumen undegradable protein (RUP) and intestinally digestible bypass protein, along with the greatest …

Duodenal and ileal digestibility of dietary nutrients and endogenous protein losses in pre- and post-weaning young dairy calves
… have shown interesting results in terms of gastrointestinal health and growth in pre- and post-weaned calves. The objectives of the series of experiments included in this dissertation were to (1) evaluate our capacity to successfully place a duodenal and ileal cannula in young calves, (2) analyze …

Determination of tannin levels in multi-purpose Kenyan trees and fodder crops, their variation and effect on protein digestibility in ruminants
… of these tannins on ruminal degradation and intestinal digestion of the diet. Samples of four multipurpose fodder trees and four forage crops viz. leucaena, sesbania, gliricidia, calliandra, velvet bean, green leaf and silver leaf desmodium and cassava, were collected at Mombasa (low …

Optimisation of quality and nutritional value of reformed/restructured meat products for older adults developed using plant proteins
… and meat protein was evaluated using in vitro digestion. Micrographs after intestinal digestion illustrated fragmentation of fibres and re-aggregation of protein molecules across all samples. Most soluble peptides had a molecular weight of < 500 Da, corresponding to peptides of less than 5 …
