以碎米为原料,糖化液DE值为考察指标,优化水料比、挤压机套筒温度、螺杆转速和进料速度等因素对挤压碎米生产淀粉糖工艺的影响。结果表明,相比于非挤压碎米,挤压碎米的液化液和糖化液还原糖含量显著增加;最佳的挤压工艺条件为套筒温度60℃,水与挤压碎米粉的质量比为12∶100,螺杆转速440 r/min,进料速度840 r/min;由方差分析可知,温度为极显著影响因子(P〈0.01)。
Taking broken rice as raw material, the effects of syrup pro- ducing process by broken rice was studied from optimization ratio of water to raw material, sleeve temperature, screw speed, federate. The result showed that the sugar content of syrup solution produced by ex- truding broken rice was higher than that produced by broken rice .The optimum technological conditions were obtained as temperature 60 ℃, the ratio of water to raw material 12 : 100, the screw speed 440 r/min, federate 840 r/min, and according to variance analysis, the temperature was a remarkable influence factor, for that P value of temperature was less than 0.01.
