摘要:

采用质构分析法、扫描电镜法以及TCA- 可溶肽的测定方法研究大豆分离蛋白(SPI)、谷朊粉(GP)和花生浓缩蛋白(PPC)对竹荚鱼鱼糜凝胶特性的影响。结果表明:SPI 添加量超过1g/100g 鱼糜时,对竹荚鱼鱼糜蛋白的降解有抑制作用;GP 和PPC 添加量超过1g/100g 鱼糜时对抑制竹荚鱼鱼糜蛋白降解的影响较小,其降解抑制率均低于10%。添加GP 和SPI 能提高竹荚鱼鱼糜凝胶的破断强度、凹陷度和凝胶强度,GP 和SPI 添加量分别在10g/100g 鱼糜和5g/100g 鱼糜时,竹荚鱼鱼糜的凝胶特性达到最大值。不同添加量的PPC 均降低了竹荚鱼鱼糜凝胶的破断强度、凹陷度和凝胶强度。添加GP、SPI 和PPC 均降低了竹荚鱼鱼糜凝胶的白度。添加GP 和SPI 能提高竹荚鱼鱼糜凝胶的持水性,但添加PPC 降低了竹荚鱼鱼糜凝胶的持水性。

Abstract:

The effects of soybean protein isolation (SPI), gluten powder (GP) and peanut protein concentrate (PPC) on the gel properties of horse-mackerel surimi were investigated by texture analysis, scanning electron microscopic observation and the determination of TCA-soluble peptides. The results indicated that addition of SPI at more than 1 g/100 g surimi inhibited the hydrolysis of horse-mackerel surimi, while the separate additions of GP and PPC exhibited little inhibition effect on the hydrolysis of horse-mackerel surimi and the inhibition rate was less than 10%. The separate additions of SPI and GP resulted in an increase in the breaking force, deformation and gel strength of horse-mackerel surimi. The best gel properties of horsemackerel surimi were observed with added GP at 10 g/100 g or added SPI at 5 g/100 g. However, the addition of PPC decreased the gel properties of horse-mackerel surimi. All of the separate additions of these kinds of non-muscle proteins resulted in a lower whiteness of horse-mackerel surimi. Separately added GP and SPI could enhance the water holding capacity of horse-mackerel surimi; however, it displayed an opposite change when PPC was added instead of the other kinds of non-muscle proteins.
