摘要:

以稻米为原料,以耐高温α - 淀粉酶为液化酶,以真菌淀粉酶和普鲁兰酶两种糖化酶协同糖化,研究稻米高纯度麦芽糖浆制取技术。结果表明:控制液化值为14 左右,糖化时真菌淀粉酶和普鲁兰酶用量分别为0.6FAU/g 干米淀粉和0.3PUN/g 干米淀粉,糖化时间控制在18h 左右、糖化温度59℃、糖化pH5.5,可以制得麦芽糖含量85% 以上的超高麦芽糖浆。

Abstract:

Liquefaction with heat-stable α-amylase and combined saccharification with fungal amylase and pullulanase for the production of high purity maltose syrup from early Indica rice were studied. Results showed that the final product containing more than 85% of maltose was obtained through liquefaction resulting in DE value followed by combined saccharification for 18 h with fungal amylase at a dosage of 0.6 FAU/g dried rice starch and pullulanase at a dosage of 0.3 PUN/gdried rice starch at 59 ℃ and pH 5.5.

Key words: early Indica rice, liquefaction, saccharification, enzyme, maltose
