Abstract: Soybean dietary fiber hydrolysate was successfully prepared by hemicellulose enzyme. The hydrolysis reaction conditions and the bacteriostatic activity of the enzymatic hydrolysate were tested. The results showed that the hydrolysate had inhibitory activity on Escherichia coli, Pseudomonassp, Staphylococcus aureus and Lactobacillus sp. When soybean dietary fiber hydrolysate was hydrolyzed by enzyme at 50℃, pH 418, Its MIC was 5.9%. The hydrolysate of soybean dietary fiber can be gotten easily, and it was valuable to develop soybean dietary fiber hydrolysate as a new natural food preservative.

Key words: Soybean dietary fiber hydrolysate, Semicellulose enzyme, Bacteriostatic activity
