Frozen Alaska pollock surimi (FA, A, and RA grades) was used to clarify how the heating method (ohmic heating and water bath heating) and heating rate affect the physical properties of heat-induced gels. Textural properties were significantly influenced by the heating method and heating rate. In 1-step heating, slow heating enhanced the gel strength of high-grade surimi more effectively than that of low-grade surimi. The quality of gels prepared by water bath and ohmic heating differed even if the heating time to the final temperature was the same, probably due to differences in the linear and non-linear temperature patterns of the two heating methods. The results of gels formed by 2-step heating and those with suppressed setting by EDTA confirmed that a slow heating rate enhanced gel strength by altering the setting phenomenon, but was also influenced by the modori effect, and the degree of enhancement differed depending on the surimi grade.
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.
