中文摘要: 在测定带鱼副产物基本营养成分的基础上,采用超声辅助盐提法制备带鱼副产物糖蛋白,考察不同因素(Na-Cl浓度、提取时间、提取温度、料液比、超声功率、超声时间)对糖蛋白得率的影响,利用响应面设计进一步对提取条件进行优化,获得带鱼副产物糖蛋白的最佳提取工艺条件。研究结果表明,带鱼副产物糖蛋白的最佳制备条件:NaCl浓度0.4 mol/L,提取时间1.5 h,提取温度78℃,料液比1:10(g/mL),超声功率525 W,超声时间21 min,在此条件下带鱼副产物糖蛋白得率为(9.20±0.20)mg/g。
Abstract:To determine the basic nutritional composition of hairtail by-products,different factors (NaCl concentration,extraction time,extraction temperature,solid-liquid ratio,ultrasonic power,and ultrasonic time)were assessed.These factors affected the rate of glycoprotein preparation.In this study,the optimal extraction conditions of glycoprotein were discovered.The results showed that the best preparation conditions for the hairtail by-product glycoprotein was as follows:NaCl concentration,0.4 mol/L;extraction time,1.5 h;extraction temperature,78 ℃;solid-liquid ratio,1:10(g/mL);ultrasonic power,525 W;and ultrasonic time,21 min.The glycoprotein yield was(9.20±0.20)mg/g.
