摘要: 以盐溶性蛋白含量、pH值、持水性、挥发性盐基氮(TVB-N)为指标,考察超高压处理的草鱼糜在-18℃冻藏期间理化性质的经时变化。结果表明:冻藏期间,盐溶蛋白含量和持水性随着压力的升高均先上升后下降,在400MPa时达到最大,分别为155.6mg/g和93.9%;盐溶蛋白含量、pH值、持水性呈下降趋势;TVB-N值呈现上升趋势。

Abstract: Physico-chemical changes of grass carp surimi treated by ultra-high pressure (UHP) during frozen storage at -18 ℃ were studied by examining salt-soluble protein, pH, water-holding capacity, and total volatile basic nitrogen (TVB-N). The results showed that salt-soluble protein content and water-holding capacity initially increased and then decreased due to increased pressure, and reached the highest level of 155.6 mg/g and 93.9%, respectively at 400 MPa. During frozen storage, salt-soluble protein content, pH and water-holding capacity revealed a decreasing trend; in contrast, TVB-N exhibited an increasing trend.
