摘要:

为解决传统鱼糕储藏难的问题,研究应用复合防腐剂有效延长鱼糕保质期的方法。通过单因素试验,从6 种防腐剂中选取了Nisin(乳酸链球菌素)、ε- 聚赖氨酸和山梨酸钾3 种对鱼糕腐败菌抑制作用较强的防腐剂;运用响应面法,复配出最优组合复合防腐剂,其配比量为Nisin 质量分数0.023%~0.034%、ε- 聚赖氨酸质量分数0.022%~0.028%、山梨酸钾质量分数0.04%~0.06%。验证实验结果表明,复合防腐剂能有效抑制鱼糕微生物的生长,在0~4℃条件下储藏,鱼糕的保质期可达10 周左右。

Abstract:

To solve the problem of short shelf life of Chinese conventional fish cake, 3 preservatives including Nisin, ε - polylysine and potassium sorbate, which exhibited better respective preserving effect than other 3 preservatives including pimaricin, ethylparaben and sodium benzoate, were simultaneously added to the fish cake formula. To minimize total number of bacteria in fish cake, the optimal amounts of added Nisin, ε-polylysine and potassium sorbate were investigated using response surface analysis based on quadratic general rotation design. Results showed that the fish cake with 0.023%-0.034% of Nisin, 0.04%-0.06% of potassium sorbate and 0.022%-0.028% ofε-polylysine exhibited a minimum total number of bacteria and its shelf life at 0 - 4 ℃ was up to around 10 weeks.
