Determination of digestible indispensable amino acid score for salmon hydrolysate proteins

Journal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4295-4301, May 2026.
Abstract BACKGROUND Salmon products are excellent foods that contain indispensable nutrients including fatty acids and amino acids (AA), but during processing, salmon co‐products that cannot be used for the primary purpose are also generated. Examples of such co‐products include salmon protein hydrolysate concentrate (SPHC) and salmon protein ...
