为解决鱼糜漂洗用水量较大这一问题，该实验以白鲢为原料，减少一次漂洗，以清水+清水为对照，比较壳聚糖溶液+清水，壳聚糖溶液+盐水，壳聚糖溶液+臭氧水和清水+臭氧水4种漂洗方式对鱼糜质构、风味等品质的影响。结果显示，壳聚糖溶液+清水或清水+臭氧水漂洗，鱼糜得率分别为21.78%和21.26%，均高于对照组的鱼糜得率19.21%；在4种漂洗方式中，壳聚糖溶液+臭氧水漂洗组的鱼糜白度最高，清水+臭氧水组的凝胶强度最大；电子鼻雷达图显示壳聚糖溶液+清水，壳聚糖溶液+臭氧水和壳聚糖溶液+盐水组的T70/2（芳香族化合物）响应值较低，而对照组和清水+臭氧水组的T70/2（芳香族化合物）响应值较高。综上所述，4种漂洗方式中清水+臭氧水漂洗可以有效地改善鱼糜品质和风味；同时，两次漂洗与传统的三次漂洗相比，减少了漂洗次数，可节约用水约1/3。

To reduce water consumption from rinsing surimi, the effects of four different rinsing methods on the quality (e.g., texture and flavor) of silver carp (Hypophthalmichthys molitrix) surimi were investigated. The four rinsing methods, which were all designed to reduce the number of rinses by one time, were chitosan solution + tap water, chitosan solution + salt water, chitosan solution + ozone water, and tap water + ozone water. A control group of tap water + tap water was also included. Consequently, rinsing with chitosan solution + tap water and tap water + ozone water resulted in surimi yields of 21.78% and 21.26%, respectively, which were higher than that of the control group (19.21%). Among the four proposed methods tested, rinsing with chitosan solution + ozone water gave the whitest surimi, whereas rinsing with tap water + ozone water led to the highest surimi gel strength. According to the radar plots from the electronic nose analysis, the surimi samples rinsed with chitosan solution + tap water, chitosan solution + ozone water, and chitosan solution + salt water had much lower T70/2 (aromatic compounds) response values than the samples rinsed with tap water + tap water (control group) and tap water + ozone water. In summary, among the four methods studied, rinsing with tap water + ozone water could effectively improve the quality and flavor of surimi. Additionally, only two rinses were needed, which would reduce water consumption by approximately ⅓ compared with rinsing three times (the traditional approach).
