The growing demand for simulated fish products coupled with the declining stocks of traditional fish species for making these products, have increased efforts aimed at developing novel procedures to put non-traditional fish species like bluefish (Pomatomus saltatrix) and tilapia (Tilapia nilotica) to better economic use. Two procedures which fulfill both objectives are (i) application of high hydrostatic pressure, and (ii) utilization of protease inhibitor to control fresh fish spoilage due to microbial activity and/or autolysis by endogenous enzymes. High hydrostatic pressure has been used to formulate gels with superior functional properties, while $ alpha sb2$-macroglobulin, a broad spectrum protease inhibitor, has been added to control proteolysis in fish gels during processing and storage. / In this study, high pressure was applied at levels of 300 to 3,742 atm for 30 min to formulate gels from bluefish meat paste, and the properties of the resulting gels were compared with those of heat-induced gels formulated at 90$ sp circ$C for 20 min or 60$ sp circ$C for 60 min. / The effects of $ alpha sb2$-macroglobulin and cooking temperatures on the properties of tilapia gels were also studied.
