Production of small peptides and low molecular weight amino acids by subcritical water from fish meal: Effect of pressurization agent and temperature

Abstract

Fish meal is a by-product obtained in the marine food industry that is actually used in aquaculture and pet-food industry. It presents a high protein content as well as a valuable lipid fraction composition. The protein fraction from marine origin has a high nutritional value and a great amino acid profile. In order to improve the use of this by-product, more sustainable forms of exploiting it must be considered and the products obtained more useful.
