Optimizing Protein Bars With Whey Protein Isolate, Pea Protein Isolate, and Blue Whiting () Fish Protein Hydrolysate: A Simplex-Centroid Mixture Design Study.

The aim of this study was to use blue whiting fish protein hydrolysate (BWFPH) as a novel dietary amino acid supplement in whey protein isolate (WPI) and pea protein isolate (PPI)-based protein bars. The findings indicate that incorporating BWFPH significantly influenced the nutritional profile of the protein bars, leading to a ~93% reduction in hardness compared to bars without the hydrolysate. Additionally, BWFPH effectively delayed the hardening process during storage.

Emaciated enigma: Decline in body conditions of common dolphins in the Celtic Seas ecoregion.

Monitoring the nutritional health of cetaceans has become increasingly important in a changing environment, where multiple stressors impact animals. Particularly for those species that require consumption of energy-dense prey, such as the common dolphin. Thus far, no uniform measure for monitoring body condition has been recommended across cetaceans, and species-specific measures may need to be developed if employed as a population condition indicator under Descriptor 1 of the Marine Strategy Framework Directive.
