Abstract

Abstract:

Microwave-assisted extraction of polysaccharide from kiwifruit roots was investigated by examining the effects of material/liquid ratio, temperature, extraction time, microwave power on polysaccharide yield using single factor method coupled with orthogonal array design. Results showed that the optimal values of the above parameters were determined as follows: material/liquid ratio 1:20 (g/mL), 60 ℃, microwave power 600 W and extraction time 15 min. Under such conditions, the yield of polysaccharide was 11.34%.

Key words: kiwifruit root, polysaccharide, microwave-assisted extraction
