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.
To reduce the rinse water of surimi and maintain the quality of surimi,potassium chloride(KCl),sodium cit-rate and carboxymethyl chitosan(CMC)were used to rinse surimi once in this experiment.In the single factor experi-ment,when the KC1 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 character-istics 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 cit-rate+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 im-proved.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.
