Abstract
This study examined the impact and mechanisms of using recycled fish oil (FO) and lard (LA) regarding the gel characteristics of surimi. It examined changes in surimi gel properties, moisture distribution, and microstructure with varying additions of FO and LA. Adding FO and LA to surimi gels reduced textural properties and gel strength, while increasing water-holding capacity (WHC), and whiteness. The FO and LA groups' G' and G′' values were lower than those of the control group, with the LA group exhibiting a higher G′ value than the FO group. Microstructural analysis showed that the oil droplets of LA group were shaped irregularly and had larger particle sizes. In contrast, the FO was more uniformly distributed within the surimi gel network. Results showed that oil changes affect the structural and physicochemical properties of surimi gels. Furthermore, FO exerted a milder impact on the surimi gel network and preserved superior gel properties compared to LA. This suggests that FO could be a valuable ingredient for producing nutrient-enriched surimi-based products.
期刊介绍:
Food Structure is the premier international forum devoted to the publication of high-quality original research on food structure. The focus of this journal is on food structure in the context of its relationship with molecular composition, processing and macroscopic properties (e.g., shelf stability, sensory properties, etc.). Manuscripts that only report qualitative findings and micrographs and that lack sound hypothesis-driven, quantitative structure-function research are not accepted. Significance of the research findings for the food science community and/or industry must also be highlighted.
