Abstract:

Choerospondias axillaris fruit pulp was added with 6-fold mass of water and then hydrolyzed using a mixture of pectinase and cellulase. The hydrolysis procedure was optimized to obtain maximum soluble solids, VC and total sugar contents in the hydrolysate by one-factor-at-a-time and L9(33) orthogonal array methods. The optimum extraction conditions were as follows: with an enzyme dose of 2400 mg/L, hydrolysis at 50 ℃ for 4 h. There were 13.12% of soluble solids, 0.51 mg/100 ml of VC and 8.49% of total sugar in the hyrolysate of Choerospondias axillaris fruit pulp prepared under the optimized conditions.

Key words: Choerospondias axillaris, bioactive component, bienzyme method, hydrolysis procedure
