Seed culture medium contains 0.5% yeast, 1% peptone, 1% soluble starch, and 1% sodium chloride, and fermentation culture medium contains 75 g wheat bran, 55 g corn flour, 25 g rice bran, 20 g soybean meal, 2 g beta -glucanase, 40 g traditional Chinese medicine powder, 35 g trehalose, 6 g yeast, 3 g corn syrup, 2 g ammonium sulfate, 2 g dipotassium hydrogen phosphate, 2 g potassium dihydrogen phosphate, 3 g sodium citrate, 0.5 g defoamers, and 1000 ml purified water. beta -glucanase containing enzyme contains 120 pts. wt. xylanase, 10 pts. wt. cellulase, 18 pts. wt. beta-glucanase, 18 pts. wt. medium temperature alpha-amylase, and 1 pt. wt. traditional Chinese medicine. Preferred Process: beta -glucanase is prepared by activating B. licheniformis strain beta -10-25 in slants, inoculating 3% to 3 L 1st stage fermentation liquid in fermentation tank, culturing at 35-45 degrees C while stirring at 200-300 r/minute with ventilation ratio (v/v) of 1:1-3 for 10-15 hours, sterilizing 1 L at 121 degrees C for 20 minutes, adding fermentation medium at 10 degrees C to fermentation tank, incubating for 15-20 hours until temperature reaches 35-45 degrees C, adding 2% inoculum fermenter to fermentation tank, incubating for 10-15 hours, sterilizing 1 L at 121 degrees C for 20 minutes, adding fermentation medium at 10 degrees C to fermentation tank, incubating for 10-15 hours until temperature reaches 35-45 degrees C, filtering fermentation liquid, concentrating, fine filtering, and drying. Fermentation culture medium is prepared by mixing purified water, corn flour, and soybean meal in mixing tank, adjusting pH to 3-7, adding medium temperature alpha -amylase for 3 U/g corn flour or high temperature alpha -amylase for 30 U/g corn flour, stirring, heating to 70 degrees C, heat preserving for 15-30 minutes, slowly heating to 90 degrees C for 15-30 minute until liquid, adding remaining raw materials, stirring, and adjusting pH to 3-7. Fermentation process is controlled by controlling dissolved oxygen of is controlled at 15-30% by adjusting stirring speed and ventilation ratio, controlling pH by adding ammonia or dilute phosphoric acid, feeding is controlled by decreasing reducing sugar content to 3-8 mg/ml while maintaining sugar content of starting feed medium at 2-5 mg/ml, and maintaining at 60-80% cell senescence autolysis.    TECHNOLOGY FOCUS - FOOD - Preferred Process: Traditional Chinese medicine is prepared by crushing 20-30 pts. wt. Astragalus root, 10-18 pts. wt. Codonopsis root, 10-15 pts. wt. Bupleurum root, and 10-15 pts. wt. Ophiopogon root to particle size of less than or equal to 2 mm, uniformly mixing with water which is 3-6 times weight of mixture, heating to 70-90 degrees C, maintaining temperature for 2-4 hours, cooling to 45-60 degrees C, adding enzyme mixture, adjusting pH to 5.5-6.8 using lactic acid, hydrolyzing for 2-4 hours, adding mixed ethanol and propanol which is 0.5-3 times weight of mixture, ultrasonicating at 110 W for 0.5-1.5 hours, filtering, vacuum concentrating, and freeze-drying.
