BACKGROUND It has been suggested that a protein hydrolysate, as opposed to its intact protein, is more easily digested and absorbed from the gut, which results in greater plasma amino acid availability and a greater muscle protein synthetic response. OBJECTIVE We aimed to compare dietary protein digestion and absorption kinetics and the subsequent muscle protein synthetic response to the inge...

Fermented milk proteins have been reported to be used for prevention and treatment of various diseases. This study was designed to investigate the anticancer effect of goat milk fermented by Lactobacillus plantarum and Lactobacillus paracasei. In vitro anticancer activity was studied using HeLa cell lines. HeLa cells were treated with milk hydrolysates and incubated at 37C for 4 h and the cell...

Prompted by the accumulating evidence on bioactive moieties of milk-derived peptides, novel methods were applied to compare the peptide composition among commercially available hydrolysate formulations and to determine batch-to-batch variations of protein hydrolysate products. Despite the availability of general methods to measure, for example, the degree of hydrolysis and peptide mass distribu...

BACKGROUND Antioxidant and chelating activities were determined in protein hydrolysates that were produced by treating a protein isolate of a non-toxic genotype of Jatropha curcas with the protease preparation alcalase. RESULTS 50 min protein hydrolysate with a degree of hydrolysis of 31.7% showed highest antioxidant and chelating activity. These activities were also determined in six peptidi...

Purpose – Infant formula is the sole nutrition and food source for many infants. Information on the free amino acid (FAA) content of formulas, particularly those that are protein hydrolysate based, is limited, despite emerging evidence for the role of FAAs in regulating eating behaviour. The purpose of this paper is to measure levels of essential, semi-essential, and nonessential FAAs in commer...

Nu-Lure and other protein solutions were presented to Anastrepha suspensa in J-tubes and consumption was quantified spectrophotometrically. In choice comparisons, flies consumed more or equal water compared to Nu-Lure and more Nu-Lure compared to Bragg’s Liquid Aminos, corn steep liquor, NZ case, pepticase, Solulys, soy hydrolysate, Torula yeast, whey, and yeast enzymatic hydrolysate. Consumpti...
