Anticancer Potential of Soy Peptides
… Soy protein hydrolysates produced by simulated gastrointestinal digestion induced L1210 cytotoxicity through apoptosis independent pathway, possibly through inducing p21 overexpression and G2/M cell cycle arrest and inhibiting topoisomerase II activities. Matrix proteins were important to the …

Determination of honey varietal’s impact on Bifidobacterium animalis ssp lactis survivability in commercial yogurt through simulated in vitro digestion
… in 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 …

Exploitation of agricultural and forestry waste: from the recovery of bioactive compounds for nutraceutical applications to the production of innovative materials
… shells was estimated through in vitro simulated gastrointestinal digestion followed by untargeted LC-ESI-LTQ-Orbitrap-MS metabolomic analyses of the resulting oral, gastric and intestinal digests. The changes in the extracts’ phytochemical composition, antioxidant/antiradical activity (FRAP, …

VALORIZATION OF CHESTNUT BY-PRODUCT FOR GASTROINTESTINAL HEALTH
… extracts was assessed by following gastric and gastrointestinal digestion. The chemical characterization confirmed the presence of bioactive polyphenols in the extracts, including ellagitannins. In CaCo-2 cells stimulated by an IL-1β-IFN-γ cocktail, nearly all chestnut by-products (50 μg/mL) …

NUTRITIONAL AND BIOACTIVE COMPOUNDS FROM AGRI-FOOD PRODUCTS AND BY-PRODUCTS: IN VITRO ASSESSMENT OF THEIR POTENTIAL HEALTH EFFECTS
… of tailored green technologies. In vitro gastrointestinal digestion models indicated good stability and bioaccessibility of several bioactive fractions, while cell-based assays using Caco-2 human intestinal epithelial cells revealed low cytotoxicity and, in selected cases, modulatory …

Invasive SIlver Carp (Hypophthalmichthys molitrix) Protein Hydrolysates- A Potential Source of Natural Antioxidant
… 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 antioxidant …

In vitro and in vivo effects of sorghum condensed tannins encapsulated in kafirin microparticles on digestive amylases
… The inhibition of SCT-KEMS after simulated gastrointestinal digestion was assessed. Electron microscopy was used to characterise microparticle morphology. A confirmatory in vivo test was performed using an oral starch tolerance test (OSTT) on healthy rats. SCT were about 20 000 times more …

Determining the mechanism of pulsed electric field for improving meat quality : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… which suggests that it may influence the digestion of meat proteins. To evaluate the impact of PEF on the protein digestion kinetics, PEF-treated beef Semimembranosus and Biceps femoris [T1 (5 kV, 90 Hz, 20 µs) and T2 (10 kV, 20 Hz, 20 µs)] and venison Longissimus dorsi [T1 (2.5 kV, 50 Hz, …

Characterization of antioxidant activities of soybeans and assessment of their bioaccessibility after in vitro digestion
… contents in an in vitro digestive system. After gastrointestinal digestion, soybean extracts contained higher TPC and ORAC values than cooked soybean (before digestion) but they were relatively low in DPPH™ radical scavenging capacity. The glucosides, daidzin, genistin, and malonylgenistin showed …

Development of in vitro infant intestinal models to assess responses to infant formulae
… GDC model was then employed to compare gastrointestinal digestion and epithelial responses to human milk, dairy-, soya-, and amino acid-based IFs. Using infant-specific digestion conditions, peptide and amino acid transport were quantified in both infant- and adult-like Caco-2/HT29-MTX …

Influence of infant milk formula processing on protein digestion and gut barrier health in vitro and in vivo
… The degree of glycation will also alter digestion. Employing lower temperatures or non-thermal processing methods, or both, should produce IMF with a higher native protein content and less advanced glycation end products. Previously, in our laboratory, a split-stream process using …

Assessment of blue whiting protein hydrolysate bioactivities using cell culture models
… the six industrial-scale BWSPHs before simulated gastrointestinal digestion (SGID) (BW-SPH-A to BW-SPH-F) and after SGID (BW-SPH-A-GI to BW-SPH-F-GI) were assessed in stimulated murine RAW264.7 macrophage. Hydrolysate BW-SPH-A (0.5%, w/v dw), both pre- and post-SGID, increased the endogenous …

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 …
