    摘要:

    为减少鱼糜漂洗用水并保持鱼糜品质,利用氯化钾(KCl)、柠檬酸钠与羧甲基壳聚糖(CMC)对鱼糜进行单次漂洗。在单因素实验中,当漂洗液中KCl质量分数为1.0%时,凝胶强度为312.28 g·cm,白度为75.28,达到最大值,显著改善其质构特性与持水性(80.98%)。当漂洗液中柠檬酸钠质量分数为0.15%时,凝胶强度为300.78 g·cm,白度为75.34,达到最大值,显著改善其质构特性与持水性(85.55%)。当漂洗液中CMC质量分数为1.2%时,凝胶强度为348.39 g·cm,白度为73.89,达到最大值,显著改善质构特性与持水性(85.48%),且持水性随CMC含量增大而递增。在此基础上进行组合漂洗1次,结果发现采用1.0%KCl+0.15%柠檬酸钠+1.2%CMC的漂洗方法改善效果最佳,漂洗后的鱼糜凝胶强度为365.62 g·cm,白度为75.31,持水性为87.12%,鱼糜得率为75.41%。与工业中的3次漂洗法相比,除了鱼糜凝胶强度下降10.55%,其它指标都显著提升。该单次漂洗方法可有效改善鱼糜品质,减少漂洗次数,且漂洗耗水量约为工业漂洗的1/3。

    Abstract:

    To reduce the rinse water of surimi and maintain the quality of surimi, potassium chloride (KCl), sodium citrate and carboxymethyl chitosan (CMC) were used to rinse surimi once in this experiment. In the single factor experiment, when the KCl quality fractions in the rinse solution is 1.0%, the gel strength is 312.28 g·cm and the whiteness is 75.28, reaching the maximum value, which significantly improves its texture characteristics and water holding capacity (80.98%). When the quality fractions of sodium citrate in the rinse solution is 0.15%, the gel strength is 300.78 g·cm and whiteness is 75.34, which reaches the maximum value, which significantly improves its texture characteristics and water holding capacity(85.55%). When the CMC quality fractions in the rinse solution was 1.2%, the gel strength was 348.39 g·cm and whiteness was 73.89, which reached the maximum value, significantly improving the texture characteristics and water holding capacity(85.48%), and the water holding capacity increased with the increase of CMC content. On this basis, combined rinsing is carried out once. It was found that the rinsing method of 1.0%KCl+0.15% sodium citrate+1.2%CMC had the best improvement effect. After rinsing, the gel strength of surimi was 365.62 g·cm, the whiteness was 75.31, the water holding capacity was 87.12%, and the surimi yield was 75.41%. Compared with the three-time rinsing method in industry, except the gel strength of surimi decreased by 10.55%, other indexes were significantly improved. This single rinsing method can effectively improve the quality of surimi, reduce the rinsing times, and the water consumption of rinsing is about 1/3 of that of industrial rinsing.
