采用石灰充碳法对菊芋提取液进行除杂,通过考虑加石灰量、充CO2量及操作温度对蛋白质去除率的影响,并对提取液中的Ca2+浓度进行控制,得出最优化条件:加石灰至pH13.4、充CO2至pH6.8、操作温度80℃.结果表明:最终蛋白质去除率为81.6%,菊粉损失为3.4%(90%以上是果糖),显示了该法在较小菊粉损失的前提下,对去除菊芋提取液中还原糖成分有显著的效果.

The study was conducted to remove impurities from inulin extract, which was extracted of Jerusalem artichoke Tubers using hot water, by the carbonation reaction between lime and carbon dioxide. The effects of amount of added lime, amount of introduced CO2 and temperature on protein reduction efficiency and Ca2+ concentraction in the inulin extract solution were investigated by single-factor method. Based on canonical analysis, the optimal conditions for maximizing protein reduction efficiency were determined as follows: adding time to pH 13.4, introducing CO2 to pH 6.8, and reaction temperature 80 ℃. The optimized process resulted in over 81.6% protein reduction and only 3.4% inulin loss (especially, over 90% fructose was contained), indicating notable efficiency to remove reduced sugars with lower loss of inulin.
