摘要
采用正交试验对海湾扇贝复合磷酸盐保水剂进行开发与优化,以解冻损失率、蒸煮损失率和盐溶蛋白热诱导凝胶保水性(WHC)为考察指标,研究焦磷酸钠、三聚磷酸钠和六偏磷酸钠对海湾扇贝闭壳肌保水性的影响。试验结果表明:复配保水剂浸泡液各成分质量浓度最佳配比为焦磷酸钠2.2%、三聚磷酸钠0.8%、六偏磷酸钠0.6%,与对照组(蒸馏水浸泡)比较,海湾扇贝闭壳肌解冻损失率从21.89%降低到-4.15%,蒸煮损失率从61.20%降低到38.54%,盐溶蛋白热诱导凝胶的保水性为2.63%。
Compound phosphate was developed and optimized by orthogonal experiment for improving the water-holding capacity of scallop(Argopectens irradias) closed shell muscle. In order to verify the effect of the phosphate, thawing loss rate, cooking loss rate and the gel water holding capacity(WHC) were tested. According to the results of orthogonal experiment L9(34), the optimum compositions were: sodium pyrophosphate 2.2%, sodium tripolyphosphate 0.8%, sodium hexametaphosphate 0.6%, compared with the control group, the thawing loss rate and cooking loss rate were respectively reduced from 21.89% to-4.15%, 61.20% to 38.54%, WHC was 2.63%.
