摘要
以蔗糖为底物 ,采用来源于米曲霉中的 β -D -呋喃果糖苷酶 (EC3 2 1 2 6)合成低聚果糖 ,酶反应最佳条件为 :反应温度 35℃ ,酶反应体系的pH为 8 0～ 8 2 ,酶浓度 2 7IU/ g(蔗糖 ) ,酶反应时间为 8h。低聚果糖的最大转化率为 5 4% ,82
A novel syrup containing fructo oligosaccharides was produced from sucrose (45%) by β D fructofuranosidase. The yield of fructo oligosaccharides production was 54.27%. The optimum reactive conditions of fructo oligosaccharides productio were pH3.5, reaction temperature 35℃, reaction time 8h, and the enzymatic concentration was 2.7?IU/g sucrose
