摘要: 研究添加谷氨酰胺转胺酶(TGase)和磷酸盐对鱿鱼鱼糜凝胶硬度和弹性的影响。结果表明:TGase和磷酸盐在鱼糜凝胶化过程中起重要作用,且不同添加量的TGase和磷酸盐均可提高鱿鱼鱼糜的硬度和弹性;单因素试验确定最佳添加量为(以鱼糜质量为基本):TGase(100U/g) 0.50%、焦磷酸钠0.30%、六偏磷酸钠0.30%、三聚磷酸钠0.30%;采取二段加热法(60℃保温1h),鱼糜的硬度、弹性达到最大。

Abstract: The effect of separate additions of transglutaminase (TGase) and phosphates on gel hardness and springiness of squid surimi was studied. The results indicated that both materials had a vital role in squid surimi gelation. The hardness and springiness of squid surimi gels could be enhanced by adding different concentrations of TGase or phosphates. Through one-factor-at-a-time experiments, the optimal amounts (based on the weight of squid surimi) of TGase (100 U/g), sodium pyrophosphate, sodium polyphosphates, and sodium tripolyphosphate added to squid surimi were determined to be 0.50%, 0.30%, 0.30%, and 0.30%, respectively. Maximum hardness and springiness were obtained by using two-stage heating (kept at 60 ℃ for 1 h).

Key words: squid surimi, TGase, phosphates, hardness, springiness.
