Starch Digestion and Phosphorus Excretion in Lactating Dairy Cows
The effects of starch and phosphorus (P) source on P partitioning and ruminal phytase activity were evaluated in eight lactating cows (113 DIM). Four cows were ruminaly cannulated. Cows were randomly assigned to treatments in a duplicated 4x4 Latin square with four, 18-d periods. Diets included dry …

African starchy foods, gastric emptying, and starch digestion in Malian stunted children
<p>Starch serves as the main energy source in cereal and tuber-rich diets, and its glycemic response profile has been associated with health-related conditions. Sorghum and millet are known to have relatively low starch digestibility, a potentially desirable property for controlling blood glucose …

Effects of Small Intestinal Starch Digestion and Dietary Lipid on Efficiency of Nitrogen Use in Cattle
… for gain from increased small intestinal starch digestion (SISD) and dietary lipid source and amount on the efficiency of N use in cattle. Five ruminally, duodenally, and ileally cannulated steers were placed in a 5 × 5 Latin square. Each received duodenal infusion of 1.5 ± 0.08 kg/d raw …

Application of a " Glucose Release Index " to assess physical and chemical characteristics of cereal grains that may influence starch digestion and subsequent energy supply to monogastrics
… energy values of grains need to be explored. Starch, which is hydrolysed into glucose by animals, is the most abundant energy component in cereal grains, and there is evidence suggesting that variations in digestible or metabolisable energy values may be related to the extent of starch …

The role of polyphenols on sugar release from carbohydrate rich foods, and the consequent impact on metabolic risk factors associated with type 2 diabetes
… resveratrol, and baobab fruit extract, on starch digestion and on markers of glycaemia. Throughout an in vitro digestion procedure, green tea and all of the polyphenol rich extracts were found to reduce starch digestion from white bread, and this effect was dose specific. These same doses …

Modelling of physical and chemical processes in the small intestine
… small intestine is an important step for food digestion and absorption. Having reviewed the literature, a relevant model has been developed which enabled investigation into the fluid flow, mixing mechanisms and delivery of nutrients to the wall of the model small intestine. Designing, …

Activity-guided fractionation of different wheat grain varieties
… and blue wheat was additionally screened for starch digestion inhibitory compounds. Overall, the profiles of the dominant antioxidants in the three wheat varieties were very similar, with the exception of anthocyanins, which are only present in the pigmented blue wheat. One novel compound, …

Starch Source, Fraction, and Processed Form Affect in Vitro and in Vivo Digestion and Glycemic Responses in Dogs
Starch plays an important role in the nutritive value of many foods and diets consumed by animals. Not only does starch provide an excellent source of ME, it also influences the way in which products can be manufactured due to its important rheological and other functional properties such as …

Oil distribution, microstructure and in vitro starch digestibility of bran-enriched magwinya
… context. Furthermore, its oil distribution, starch digestion and microstructure have not been documented. It is against this background that this research was carried out. Firstly, a survey of the production process, ingredient formulation, sales, characteristics and consumption of magwinya …

Interactions of Phenolic Monomers With Digestion and Metabolism
… cornstalks with rumen fluid resulted in apparent digestion of phenolics associated with cell wall material. Roughages differed in digestibility of specific compounds. Inclusion of roughage phenolic monomers in a semipurified substrate for the fermentation with rumen microorganisms depressed …

Study of the Effect of Feeding Highly Digestible Corn Based Calf Starter on the Growth Performance of Calves
… Choice (MC) that vary in energy density and starch digestibility. These MC hybrids have lower starch densities due to an altered starch structure, which allows for greater ruminal and intestinal starch digestion. The altered starch structure of these new hybrids results in reduced feed …

Evaluating the effect of dietary changes and management strategies to feedlot cattle during the adaptation and finishing phase on performance, carcass characteristics and the rumen microbiome
… utilize diets containing high concentrations of starch to maximize energy intake. An adaptation period is necessary to allow the microbial community in the rumen to adjust from forage-based diets to high starch diets. These adaptation diets have greater inclusions of forages and are usually …

Can polyphenol-rich millets affect glycaemic response, insulinaemic response and gastric emptying in prediabetes?
… 2) investigate the effect of a millet muffin on starch digestion in vitro, 3) conduct a sensory evaluation test to assess the overall acceptance of millet muffins, and 4) determine the effect of a millet muffin on endogenous markers of glycaemia in prediabetic individuals. This PhD study was able …

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 …

INHIBITION OF ACTIVITIES OF INDIVIDUAL SUBUNITS OF INTESTINAL MALTASE-GLUCOAMYLASE AND SUCRASE-ISOMALTASE BY DIETARY PHENOLIC COMPOUNDS FOR MODULATING GLUCOSE RELEASE AND GENE RESPONSE
… world. Since free glucose is released through digestion of starch in the human diet, control of the starch digesting enzymes, particularly the intestinal mucosal alpha-glucosidases [Maltase-Glucoamylase (MGAM) and Sucrase-Isomaltase (SI)], has a potentially important role in both the etiology …

Dietary carbohydrates influence the structure and function of the intestinal alpha-glucosidases
<p>As the primary products of starch digestion by pancreatic α-amylase, maltooligosaccharides (including maltose) are the main substrates for the α-glucosidases at the intestinal brush border. Here, maltose was shown to induce the formation of a higher molecular weight (HMW) sucrase-isomaltase (SI) …

Tannin – starch interplay: Investigating the impact of grape tannins on the properties of various starches : A dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Food Innovation at Lincoln University
Starch is a vital macronutrient found in different concentrations across various foods. The structure and physicochemical properties of starch can vary from one source to other, directly or indirectly influencing how it interacts with other bio-macromolecules in the food systems. Interaction of …

Closing the fibre gap in refined cereal product – quality and health
… enrichment with cellulose, pectin, and resistant starch (RS) type IV improved sensory and techno-functional properties while reducing starch digestibility. The optimised pasta is high in fibre, with a 125% increase in DF compared to the control pasta. A similar strategy was applied to cake using a …
