摘要:

为开发高品质扇贝肉糜制品,本文以冷冻海湾扇贝(Argopecten irradians)贝柱为原料,选取大豆分离蛋白、羟丙基木薯淀粉、卡拉胶、蛋清添加至扇贝肉糜,探讨外源添加物对扇贝肉糜凝胶特性及营养品质的影响。结果表明,5%大豆分离蛋白(B组)和羟丙基木薯淀粉(C组 )能有效改善扇贝肉糜质构特性,且后者显著提高扇贝肉糜制品的持水性,但8%蛋清(D组)或0.6%卡拉胶(E组)会降低扇贝肉糜的硬度、内聚性、弹性和持水力;复配外源添加物[F组(7%羟丙基木薯淀粉+1.0%卡拉胶)和G组(8%羟丙基木薯淀粉+1.5%卡拉胶+5%蛋清+4%大豆分离蛋白)]对扇贝肉糜质构影响较小且能够提高持水性;F组感官评价较高;C、F、G组的扇贝肉糜制品均具有较优的氨基酸、脂肪酸配比,但氨基酸组成差异明显,不饱和脂肪酸含量显著高于饱和脂肪酸,EPA+DHA含量分别占总脂肪酸的45.04%、44.74%和30.87%。由此可知,外源添加物的种类和添加比例会显著影响海湾扇贝肉糜的凝胶特性和营养品质,为后续开发不同质构和成本等级的扇贝肉糜制品提供了理论数据。

Abstract:

In order to develop high quality scallop mince products, this paper took frozen Argopecten irradians scallops as the raw material, and selects soybean isolate protein, hydroxypropyl cassava starch, carrageenan, and egg albumen to be added to the A.irradians mince, which explored the effects of exogenous additives on the gelatinization characteristics and nutritional quality of A.irradians mince.The results showed that 5% soybean isolate protein (Group B) and hydroxypropyl cassava starch (Group C) were effective in improving the textural properties when added to A.irradians mince respectively, and the latter was able to significantly improve the water-holding capacity of A.irradians mince products, but 8% egg albumen (Group D) or 0.6% carrageenan (Group E) decreased the hardness, cohesiveness, springiness, and water-holding capacity of A.irradians mince. The combination of exogenous additives (Group F: 7% hydroxypropyl tapioca starch, 1.0% carrageenan,Group G: 8% hydroxypropyl cassava starch+1.5% carrageenan+5% egg albumen+4% soybean isolate protein) had a lesser effect on the fabrication structure of the A.irradians mince and was able to improve the water-holding capacity. Group F A.irradians mince products had higher sensory ratings in terms of flavor, color and histomorphology. The A.irradians mince products from groups C, F and G all had superior amino acid and fatty acid ratios, with significant differences in amino acid composition, and significantly higher unsaturated fatty acid contents than saturated fatty acids. The content of EPA+DHA accounted for 45.04%, 44.74% and 30.87% of the total fatty acids, separately. It could be seen that the type and proportion of exogenous additives significantly affect the gelatinization behavior and nutritional quality of minced scallop meat in A.irradians, providing theoretical data for the subsequent development of scallop mince products with different textural structures and cost levels.
