This study optimized the formulation of protein-enriched vegetable purees designed for people with swallowing difficulties and investigated effect different storage conditions (freezing refrigeration) on their nutritional, rheological textural properties. Two proteins (casein pea protein) four hydrocolloids (guar gum, tara xanthan gum carboxymehtylcellulose) were combined behavior analyzed. The...

The digestion rate of dietary protein is a regulating factor for postprandial metabolism both in humans and animal models. However, few data exist about the habitual consumption of proteins with different digestion rates with regard to the development of body mass and diet-induced obesity. Here, we used a factorial ANOVA design to investigate the effects of protein form (intact vs. hydrolyzed c...

BACKGROUND Starch is a main source of glucose and energy in the human diet. The extent to which it is digested in the gastrointestinal tract plays a major role in variations in postprandial blood glucose levels. Interactions with other biopolymers, such as dairy proteins, during processing can influence both the duration and extent of this postprandial surge. OBJECTIVE To evaluate the effect ...

Adsorption of proteins onto a solid surface is believed to be the initial and controlling step in biofouling. A better knowledge of the fouling process can be obtained by controlling the formation of the first protein layer at a solid surface. A number of methods have been investigated to inhibit adsorption of proteins. In this study, the adsorption kinetics of -casein onto bimodal PEG brushes ...

Dietary cooked casein promotes colon cancer in rats. We speculated and tested the hypothesis that cooking reduces the digestibility of casein, and increases the yield of bacterial metabolites, which are potential promoters of cancer. We investigated dietary means to manipulate nitrogen transfer and fermentation in the caecum. The caecal digestion of casein (cooked or not), keratin (hydrolysed o...

We have utilized primary cultures of rat mammary epithelial cells to study mechanisms by which laminin regulates the prolactin-dependent accumulation of alpha-casein mRNA. Mammary cells accumulate approximately fivefold more alpha-casein mRNA when cultured on laminin than when cultured on tissue plastic and the accumulation of alpha-casein mRNA is prolactin dependent. On the basis of transcript...

Casein kinase I activity is present in cells as a cytosolic and a membrane-bound enzyme. Previously, the erythroid membrane-bound casein kinase I was shown to associate with purified integral membrane proteins; this association and protein kinase activity was regulated by phosphatidylinositol 4,5-bisphosphate (PIP2) (Bazenet, C.E., Brockman, J.L., Lewis, D., Chan, C., and Anderson, R.A. (1990) ...

Dietary restriction extends adult Drosophila melanogaster life span when the concentration of dietary yeast is diluted in a media with abundant carbohydrates. Here we vary the concentration of casein as a source of amino acids in adult diet to uncover a quality of nutrient yeast responsible for longevity control. Longevity is maximized upon diet with intermediary levels of casein. Differences i...
