Abstract:

The soluble dietary fiber is a very important functional food base material recognized as an international consensus. In order to discuss the effect of adding enzyme amount, solid\|liquid ratio, enzymolysis temperature and time, this study took jujube fruit residues as material and extracted soluble dietary fiber by cellulase. The single factor and orthogonal array design experiments were carried out. The results indicated that the optimal procedure for producing soluble dietary fiber was cellulase dose of 4%, 1∶15 solid\|liquid ratio, enzymolgysis at 50℃, for 1.5 hour. Under this conditions, the yield of dietary fiber could reach 6.20%. This study would provide reference data for comprehensive utilization of jujube fruit residues, and enrich the material source of edable fiber.
