摘要:

以粉末活性炭对酶法生产的低聚果糖溶液进行吸附脱色,研究活性炭的用量、脱色温度及脱色时间对脱色效果的影响。在单因素试验的基础上,利用响应曲面法对低聚果糖溶液脱色进行优化。得到最佳工艺条件为活性炭的用量22g/L、脱色温度60℃、脱色时间30min,在此条件下低聚果糖溶液的脱色率达79.16%。

Abstract:

Activated carbon powder was used for the adsorptive decolorization of the enzymatically prepared fructooligosaccharide solution in our laboratory, and the effects of the dosage of activated carbon as well as decolorization temperature and time on decolorization rate and fructooligosaccharide loss rate were studied. On the basis of single factor experiments, response surface methodology was employed to optimize the above three conditions. Their optimal levels were found to be: 22 g/L activated carbon dosage used for 30 min decolorization at 60 ℃. Under these conditions, the rate of decolorization of fructooligosaccharides solution was 79.16%.

Key words: fructooligosaccharide solution, activated carbon, decolorization, response surface methodology
