中文摘要: 该文采用正交设计的方法研究焦磷酸钠(sodium pyrophosphate,SPP)、三聚磷酸钠(sodium tripolyphosphate,STP)、六偏磷酸钠(sodium hexametaphosphate,SHP)及柠檬酸钠(sodium citrate,SC)对牛肉盐溶蛋白凝胶保水性的影响。结果表明:SPP、STP、SHP、SC 的最佳质量配比为 2∶2∶2∶3,添加量为 0.5%时,保水率可达 94.03%。将不同条件处理的盐溶蛋白溶液进行十二烷基磺酸钠-聚丙烯酰胺凝胶电泳(sodium dodecyl sulphate-polyacrylamide gel electrophoresis,SDS-PAGE),发现盐溶蛋白凝胶保水性的差异是由于蛋白质含量的不同所致。
Abstract:The effects of sodium pyrophosphate(SPP),sodium tripolyphosphate(STP),sodium hexametaphosphate(SHP)and sodium citrate(SC)on the water-holding capacity of beef salt soluble protein gel was studied by orthogonal design.The results showed that the optimum mass ratio of SPP,STP,SHP and SC was 2∶2∶2∶3.The water-holding rate could reach 94.03%while the addition amount was 0.5%.The difference in waterholding capacity of salt soluble protein gel was in relation to the difference of protein content through SDSPAGE technology.
