Third, the process operation
1, raw material processing selection of high quality soybeans into the tank or soak for about 2 hours, washed and drained into the steaming pot steamed.
2. Inoculated soybean clinker was reddish-brown with a slight odor of beans. After cooling, mix 4% of misoprost bacteria into the mixture.
3. The koji inoculated and homogenized bean material is distributed in bamboo rafts, 2-3 cm thick, and sent to a 30-35Â°C indoor room-made koji. After 10 hours of material temperature rise and ventilation, the material temperature was reduced to 32-36Â°C and the optimum temperature was 33Â°C. After 16-18 hours, the Aspergillus oryzae spores are germinated and the mycelium is propagated using hand-twisting (called turning). In exchange for fresh air and carbon dioxide. After another 7-8 hours turn the second song.

6. For the second fermentation, the raw material of bean curd after the first fermentation and the above-mentioned raw materials such as Chinese herbal medicines and white spirits are added to the cylinder according to the ratio of the aforementioned soybean raw materials, and then poured into salt water at 23Â° C. (the ratio of raw material and salt water is 1:1. .8). After 3 months of natural sun exposure, it is mature sauce.
7. Dip oil The mature sauce shall be placed in a filterable pot or ceramic tile pool and dip into the salt water for 2 times. Leaching soy sauce sweat sticky, red brown color, sweet taste.
