Reprint of "food-grade electrospinning of proteins"

Developing non-meat food products with an appealing structure is a challenge. In this study, we investigate the possibility to produce thin fibrils as building blocks for texturally interesting meat replacers. The technique applied is electrospinning - a technique which produces thin fibrils with a high aspect ratio. The spinning of proteins is...

Health issues of whey proteins: 1. Protection of lean body mass

Loss of muscle mass as a consequence of changes in protein metabolism during periods of catabolic stress is a serious complication in a variety of conditions. These conditions are weight loss programs, sarcopenia in the elderly and several clinical states. It appears from many studies that improved protein nutrition by ingestion of high-quality...

The Protein Digestibility-Corrected Amino Acid Score (PDCAAS) - A concept for describing protein quality in foods and food ingredients: A critical review

Protein Digestibility-Corrected Amino Score (PDCAAS) is discussed. PDCAAS is now widely used as a routine assay for protein quality evaluation, replacing the more traditional biological methods [e.g., measurement of the Protein Efficiency Ratio (PER) in rats]. PDCAAS is based on comparison of the essential amino acid content of a test protein...

Ideal amino acid profile and dietary lysine specification for broiler chickens of 20 to 40 days of age

1. The aim of the study was to determine the ideal ratio of the essential amino acids lysine (Lys), methionine (Met), threonine (Thr), tryptophan (Trp), arginine (Arg), valine (Val) and isoleucine (Ile) and to assess the required dietary lysine concentration for optimum performance in broiler chickens of 2 commercial strains from 20 to 40 d of...
