The purpose of this research work was to take advantage of rainbow trout by-products in the preparation of an enzymatic hydrolyzate and to determine the presence of peptides with antioxidant capacity, since these by-products are generally disposed of in rivers or are buried, causing potential damage to the environment. The research analyzed the effect of two types of enzymes (Protamex and Flavourzyme) to carry out the hydrolysis process and determine which of the two had the greater antioxidant capacity. For this purpose, a Box Behnken-type response surface design with 15 treatments was applied, where the independent variables: percentage of enzyme, time and PM: solvent ratio were optimized according to the response variable degree of hydrolysis (GH). The results obtained after optimization for the Flavourzyme enzyme were: degree of hydrolysis 63.35 % applying 0.5 % enzyme, 180 minutes and a MP:solvent ratio of 0.50 g trout/ml H2O; for the Protamex enzyme were 52.08 % degree of hydrolysis, 0.5 % enzyme, 120.6 minutes and a MP:solvent ratio of 0.50 g trout/ml H2O. On the other hand, the antioxidant capacity after the hydrolysis process using Protamex and Flavourzyme enzymes by DPPH methodology was 76.44 and 74.97 percent inhibition and ABTS was 16702.79 and 6545.20 TEAC respectively. It is concluded that the protein hydrolysate obtained by the Flavourzyme enzyme had a higher degree of hydrolysis than the Protamex, on the other hand, it was determined that the influence of the Protamex enzyme on the release of antioxidant peptides during the hydrolysis process was better than that found using the Flavourzyme enzyme.
