大米糖粕酸法水解制糖的研究

The Syrup Processing by Hydrolyzing Rice Syrup Dregs with Acid

用盐酸水解大米糖粕，正交试验表明，当ＨＣｌ 浓度为０１４ ｍｏｌ／Ｌ，糖粕质量浓度１４ ｇ／ｄＬ、温度１３０ ℃、时间５０ ｍｉｎ 时，大米糖粕出糖率最高，达５２１２ ％ 。检测此条件下滤出糖液的色相、总氨基酸态氮含量等指标，表明糖液可用工厂精制系统精制，同时滤渣干基粗蛋白质含量提高到０７０７ ０ ｋｇ／ｋｇ 。

HCl was used to hydrolyze syrup dregs. The results of orthogonal experiment showed that syrup yield of rice syrup dregs was the highest, reaching 52.16%, and rough protein content of filter dregs reached 0.707 0 kg/kg,when the concentration of HCl was 0.14 mol/L,mass concentration of rice syrup dregs was 14 g/dL, temperature was 130 ℃, time was 50 min. By examing the RBU value and the content of total amino N of filter syrup under this condition,it was proved that filter syrup could be refined by the factory's refining system.
