Small-scale mud carp (SC, Cirrhina microlepis) and common carp (CC, Cyprinus carpio) are underutilized freshwater fish. The objective of this study was to elucidate the gel-forming ability of mince and washed mince from these species in relation to washing cycles and CaCl 2 addition. Protein loss of up to 67% was observed after three-washing cycles of both species, rendering relatively low yield. About 85-90% of total fat was removed from SC flesh after three-washing cycles, but only two-washing cycles were sufficient for fat removal in CC mince. Mince and washed mince of both species did not exhibit severe proteolysis with low autolytic activity at 65 • C. SC exhibited superior gel-forming ability to CC. Two-and three-washing cycles in conjunction with a 40 • C-preincubation resulted in the highest textural properties of SC and CC, respectively. CaCl 2 increased the breaking force of CC and SC mince gels up to 65 and 95% at 0.3 and 0.5% CaCl 2 , respectively, as compared to without CaCl 2 . However, it showed negative effects on surimi gels of both species. Both SC and CC are potential freshwater fish resources for mince and washed mince production with reasonable good gel-forming ability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
