Abstract

Objective: To optimize depigmenting technology of polysaccharides from Portulace oleracea with activated carbon. Method: On the basis of single-factor tests

according to Box-Behnken center-united experimental design principles

response surface analysis of three factors and three levels was adopted with activated carbon dosage

depigmenting time and temperature as factors.A second order quadratic equation for de-colorization of polysaccharides was built

after analyzed significance of three factors

optimal decolorization conditions of polysaccharides solution was concluded. Result: Optimal decolorization technology were as follows:the amount of activated carbon 30 g·L-1

decolorization time 50 minutes

decolorization temperature at 40℃.Under these conditions

decolorization rate of polysaccharides was up to 68.05%. Conclusion: This optimized decolorization technology was simple and stable with good predictability.
