Abstract

Butter fat was interesterified in a medium of low water content in the absence of a solvent with P. fluorescens lipase as catalyst at various temperatures. In the reaction products of interesterifications at 50 o C and 60 o C, the TAG compositions determined by GLC, and the FA compositions at the sn-2 position determined by enzymatic deacylation, were close to random, indicating the positional non-specificity of P. fluorescens lipase under the reaction conditions used
荧光假单胞菌脂肪酶在无溶剂条件下催化牛油脂肪的酯化反应
以荧光杆菌脂肪酶为催化剂,在不同温度下,在无溶剂的低含水量培养基中对牛油进行了酯化反应。在50℃和60℃的反应产物中,GLC测定的TAG组成和酶解去酰化测定的sn-2位置FA组成接近随机,表明P. fluorescens脂肪酶在所使用的反应条件下具有位置非特异性
