摘要: 为了充分利用乌贼下脚料乌贼眼,对酶法提取金乌贼眼中透明质酸工艺进行研究。结果表明,在胃蛋白酶、中性蛋白酶、胰蛋白酶的筛选实验中,中性蛋白酶的提取率最高,为6.64%,是酶解最适酶。采用单因素试验和响应面法研究中性蛋白酶酶解金乌贼眼中透明质酸的工艺条件。结果表明,影响提取率的工艺因素顺序为加酶量>酶解时间>酶解温度;其酶解最佳工艺条件为加酶量8200U/g、酶解时间3h、酶解温度60℃,在此条件下透明质酸提取率10.70%,与模型预测值基本相符。响应面优化酶法提取金乌贼眼透明质酸条件准确可行。

Abstract: In order to make full use of golden cuttlefish eyes, the enzymatic preparation of hyaluronic acid (HA) from the waste of golden cuttlefish processing was studied. The results of a comparison of 3 proteases showed that neutral protease was more suitable to hydrolyze golden cuttlefish eyes than pepsin and trypsin, providing an HA extraction yield of 6.64%. Employing one-factor-at-a-time experiments and response surface methodology, the optimal conditions for HA extraction by neutral protease-catalyzed hydrolysis were determined as follows: 8200 U/g enzyme amount and 60 ℃ for a reaction duration of 3 h. Under these conditions, the experimental extraction yield of HA was up to 10.70%, in close agreement with the predicted value. Accordingly, the established extraction process was accurate and feasible. It was also found that enzyme amount was the most important fact the affects extraction yield of HA followed by temperature and reaction time.
