摘要

本研究对10种常见食用贝类成体的淀粉酶在不同pH值、不同温度条件下进行了活性测定。结果表明,其总体消化器官淀粉酶的最适温度为:青蛤(Cyclina sinensis),33℃;缢蛏（Sinonovacula constricta),32℃;文蛤(Meretrix meretrix),43℃;等边浅蛤(Gomphina veneriformis),35℃;菲律宾蛤仔(Ruditapes philippinarum),34℃;泥螺(Bullacta exarata),40℃;彩虹明樱蛤(Moerella iridescens),37℃;微黄镰玉螺(Lunatica gilva),43℃;锈凹螺(Chlorostoma rusticum),43℃;疣荔枝螺(Thais clavigera),43℃;淀粉酶的最适pH值范围为4.6-4,9,不同贝类稍有不同;同一种类中肝脏淀粉酶的活性大于肠淀粉酶的活性。

Abstract

Amylase activity of 10 species of Common edible mollusks were investigated under different PH values and temperatures. The results were as following: 1.The optimum temperature of amylase activity is 32℃ for Sinonovacula constricta,33℃ for Cyclina sinensis, 43℃ for Meretrix meretrix, 35℃ for Gomphina veneriformis, 34℃ for Ruditapes philippinarum,37℃ for Moerella iridescens, 43℃ for Lunatica gilva and Thais clavigera,40℃ for Bullacta exarata and 43℃ for Chlorostoma rusticum. 2. The optimum PH value for amylase activity varies from 4.6 to 6.9. 3. The amylase activities in two organs of one individual are different (liver>intestine).
