This study was designed to compare the acute response of mixed muscle protein synthesis (MPS) to rapidly (i.e., whey hydrolysate and soy) and slowly (i.e., micellar casein) digested proteins both at rest and after resistance exercise. Three groups of healthy young men (n = 6 per group) performed a bout of unilateral leg resistance exercise followed by the consumption of a drink containing an eq...

A bovine alpha s1-casein tryptic hydrolysate was previously demonstrated to display an anxiolytic-like activity in the conditioned defensive burying and in the elevated plus-maze models when i.p. injected. The present study assessed the anxiolytic-like effects of this tryptic hydrolysate after an oral administration in rats faced to the same behavioural situations using diazepam as a reference....

Peptides with bioactive properties can be released from the precursor proteins during food processing or digestion, and act as antioxidative compounds. Although, it has been proven that hydrolysate exerts higher antioxidant activity than purified peptides. The process of enzyme immobilization proved to be more practical and advantageous for catalysis than using free enzyme. The aim of this stud...

The peptidases of thermophilic lactic acid bacteria have a key role in the proteolysis of Swiss cheeses during warm room ripening. To compare their peptidase activities toward a dairy substrate, a tryptic/chymotryptic hydrolysate of purified beta-casein was used. Thirty-four peptides from 3 to 35 amino acids, including three phosphorylated peptides, constitute the beta-casein hydrolysate, as sh...

Previous reports from this laboratory (2, 3) have described the rapid induction of threonine dehydrase and ornithine transaminase in rat liver by the force feeding of casein hydrolysate. Preliminary evidence that this induction was repressed by dietary glucose, but not by dietary fat, was also presented (2). The present paper includes a comparison of the induction patterns obtained by casein hy...

Microbiol. 13:426-431. 1965.-The growth of Pasteurella haemolytica strain H44L was studied under aerobic conditions in a medium of acid-hydrolyzed casein, supplementary cysteine, inorganic salts, vitamins, and a carbon source. The concentration of casein ...

The growth yield of Thiobacillus intermedius is greater in glucose-yeast extract or glucose-casein hydrolysate broth than in comparable media without glucose. The quantity of glucose utilized in the glucose-supplemented media is much greater than the increase in cell yield observed relative to the unsupplemented media. Addition of glucose to cell-free extracts of glucose-yeast extract or glucos...

OBJECTIVE To examine the effects of alpha (s1)-casein hydrolysate on females with stress-related symptoms. DESIGN Double-blind, randomized, crossover, placebo-controlled trial. SETTING The alpha (s1)-casein hydrolysate was manufactured by INGREDIA (Arras, France) and the placebo was manufactured by DIETAROMA (Bourg, France). Study was designed and performed at PROCLAIM (Rennes, France), and...

A major problem in total parenteral nutrition is sepsis, particularly that caused by Candida. Studies of four solutions, a casein hydrolysate, a fibrin hydrolysate, and two crystalline amino acid solutions, show that the protein hydrolysate solutions appear to be highly selective for Candida over bacteria, whereas the crystalline amino acid solutions are not. These findings suggest that the cry...
