摘要
采用酶学分析方法,研究了不同pH值对卡拉白鱼肝胰脏、前肠、中肠、后肠内蛋白酶、淀粉酶、脂肪酶活性的影响。结果表明,在pH值设定范围内,蛋白酶、淀粉酶和脂肪酶最适pH值范围分别为7.0～7.8、7.2～7.6、6.6～7.6。前肠是唇进行蛋白质消化的主要场所,中肠的淀粉酶活力最高,肝胰脏的脂肪酶活力最强。
The effects of different pH values on digestive enzymes in hepatopancreas, foregut, midgut and hindgut of Hemibarbus labeo Bleeker were studied by enzyme analysis method. The results show that in the setting concentration ranges, the optimum pH values range for protease, amylase and lipase were 7.0-7.8, 7.2-7.6, 6.6-7.6, respectively. The strongest protease activity is in foregut, the strongest amylase activity is in midgut, while the strongest lipase activity is in hepatopancreas.
