Abstract

In this paper,Extraction conditions of pectin from Hanzhong orange peel,such as temperature,pH-value,time,feedstock ratio and Cellulase dosage were studied.The optimal conditions were obtained by a series of mono-factor experiments and L16(45)orthogonal test.Variance analysis indicated that the optimal extraction conditions were:temperature 55 ℃,pH7.0,extraction time 2.5h,liquid ratio 1 ∶20,the amount of 0.25% cellulase.Pectin yield can reach 17.31% under the optimal condition.
