摘要:

以巴沙鱼皮为原料,研究鱼皮超声乳化法脱脂工艺。对脱脂工艺过程中的脱脂剂种类、超声时间、脱脂剂浓度、料液比等因素进行系统性的研究。脱脂剂选择结果显示表面活性剂NP-10结合超声脱脂效果较优。在此基础上,通过单因素试验和正交试验确定了较优工艺为选择体积分数1%的NP-10溶液,在超声功率密度为2.22×104W/m3条件下超声处理3h,料液比为1:5.5(g/mL)。在此条件下,鱼皮的脱脂率为82.59%,胶原蛋白损失率为5.32%。

Abstract:

Ultrasonic emulsification was used to degrease Basa fish skin. In the degreasing process, the operating parameters degreasing agent type and concentration, ultrasonic treatment time and solid-to-liquid ratio were investigated. Surfactant NP-10 was found to be the most effective agent for degreasing fish skin. The optimum conditions for degreasing fish skin were established as follows: 1% NP-10 solution as a degreasing agent at a solid-to-solvent ratio of 1:5.5 (g/mL) and ultrasonic treatment at a power density of 2.22 × 104 W/m3 for 3 h. Under these conditions, the degreasing efficiency and collagen loss rate of fish skin were 2.59% and 5.32%, respectively.

Key words: Basa fish skin, degreasing rate, collagen
