摘要:

研究加热条件对竹荚鱼鱼糜凝胶特性的影响,主要采用质构分析法、扫描电镜法、持水力、白度、TCA-可溶性肽含量和鱼糜凝胶溶解度的测定等方法研究凝胶化温度、凝胶化时间和加热方式对竹荚鱼鱼糜凝胶特性的影响。结果表明:凝胶化温度、凝胶化时间和加热方式影响竹荚鱼鱼糜的凝胶特性。竹荚鱼鱼糜凝胶的制备宜采用30℃凝胶化5h 或40℃凝胶化4h,然后90℃加热20min 的二段加热方式,竹荚鱼鱼糜形成了高度致密、均一的三维网络结构。50~70℃凝胶化后,竹荚鱼鱼糜形成大小不一的凝胶孔洞,凝胶网络的致密性下降,呈现出明显的凝胶劣化现象。

Abstract:

Effects of heating conditions, including setting temperature, setting time and heating method on the gel properties were investigated by texture analysis and determinations of whiteness, water-holding capacity, microstructure, TCA-soluble peptides content, protein solubility. Results showed that heating temperature, time and method all had a significant effect on the gel properties of horse mackerel surimi. The optimum condition for processing horse-mackerel surimi was a two-step heating method with setting at 30 ℃ for 5 h (or at 40 ℃ for 4 h) and then heating at 90 ℃ for 20 min, which resulted in the formation of high compacted and uniformed three dimensional network structure observed under scanning electronic microscopy (SEM). Horsen mackerel surimi gel showed a structure with aggregates of sparse packed spherical proteins, arranged in clusters when setting at 50-70 ℃, which indicated the modori phenomena occurred.

Key words: horse-mackerel surimi, heating condition, suwari, modori, gel properties
