The aim of the work was to assess the impact of thermal processing, enzymatic hydrolysis, and simulated digestion on the biological activity of mackerel meat and obtained hydrolysates. As a result of thermal treatment, a change in the antiradical activity of 2,2-diphenyl-2-picrylhydrazyl (DPPH), the ability to reduce iron ions, and a change of iron ions were observed in mackerel meat. The enzymatic hydrolysis process contributed to a significant increase in antioxidant activity. The simulated digestion of the obtained mackerel hydrolysates caused slight changes in the Fe2+ chelation capacity and the ferric reducing ability of plasma (FRAP) parameter, while significantly reducing the scavenging capacity of DPPH radicals. In addition, mackerel protein hydrolysates subjected to various types of heat treatment are a good source of peptides with ACE-inhibitory properties. The obtained results suggest that the heat treatment of mackerel meat carried out before the enzymatic hydrolysis process influences the biological activity of the obtained protein hydrolysates. Moreover, a suitable cooking technique when preparing raw material may be used to obtain hydrolysates with higher biological activity. Consequently, the obtained hydrolysates may be effectively used as a functional food ingredient.
