摘要
为了探讨膨化玉米制作玉米汁的最优糖化条件,文中利用膨化技术对玉米进行预处理,利用响应面分析法优化了糖化反应温度、pH值、液固比。结果表明:利用膨化处理缩短了玉米汁生产周期,降低了能源消耗,提高了生产效率。并且最适的糖化条件为:温度60℃、pH值4.6、液固比6∶1(mL∶g)。在此条件下,膨化玉米的最终还原糖产量达到0.58 g/g。
To explore the optimal conditions of corn beverage from extruded corn, the pretreatment technology, and optimization of the saccharification reaction temperature, pH, and the ratio of material to water were determined by response surface methodology. The results showed that the extruding treatment shortened the corn beverage process- ing, lower the energy consumption and increased the production efficiency. The optimal conditions were： reaction temperature 60℃ , pH value 4.6, the ratio of material to water 6 mL/g. Under the above condition, the ultimate re- duced sugar content of extruded corn reached to 0.58 g/g.
