EFFECTS OF SPECIES AND STORAGE TIME ON MINCED FISH GEL TEXTURE

Protein functionalities were studied in comminuted fish gels from mechanically deboned fish tissues of four species after storage at −29° C up to 12 months. Differences in gel textures, which were evaluated instrumentally and by a texture profile sensory panel, were evident among fish species and time in frozen storage. Fish gel texture was not significantly related to, protein solubility of raw tissues, but was closely related to water‐holding capacity and protein solubility of cooked gels. Degradation of tropomyosin and myosin probably occurred in some of the fish gels during thermal processing. Copyright © 1979, Wiley Blackwell. All rights reserved
