Abstract: A production method of low molecular weight ?-glucan includes: inoculating an activated Leuconostoc mesenteroides in a 5 L fermentor at a 10% inoculum. Fermentation broth is placed in the fermentor at an initial pH of 6.8-7.0, temperature of 25° C. to 28° C., stirring speed at 120 r/min, and fermented for 20-40 hours. Dextranase is added after 5-30 hours of fermentation at a dosage of 1/10,000 to 5/10,000 by volume. The molecular weight of ?-glucan is controlled within 10000D by the amount of enzyme added, and the total fermentation process is about 20-40 hours. After the reaction is terminated, the fermentation liquid is concentrated and dried to prepare dietary fiber products with a molecular weight of 500-5000D. The viscosity of the fermentation liquid and concentration of ?-glucan in the fermentation liquid may be reduced to promote the forward reaction, accelerate the sucrose conversion rate and increase the product yield.
