First, use new harvested, non-toxic beans to grow bean sprouts. Before cultivating, wash with clean water, dip it in water at 65°C for 1 minute (the surface of the water is 15 cm higher than the beans), immediately rinse with heat to room temperature, and soak in water after filtering.
Second, soaking, showering water quality is better. Soak and rinse the beans with tap water. Do not use any water, sewage, or saline water.
Third, pay attention to adjust the temperature and humidity. It is advisable to keep the temperature at 20~28°C. It should not be too high or low. Attention should be paid to frequent inspections. When the temperature is low, the doors and windows of the germination room should be closed, and the warm water and the film on the tank must be tightly sealed. When the temperature is high, the cover film should be opened to pour the water with a slightly lower temperature, and be careful of pouring. Pouring thoroughly. The relative humidity of the air in the cylinder is about 90%, and the adjustment mainly depends on the watering. In general, the temperature is higher in the season and water is sprayed once every 3 to 4 hours. In the lower temperature season, water is sprayed every 5 to 6 hours. In addition, bean sprouts and bean sprouts are minimized and avoided during the production of bean sprouts.
Fourth, prevent bacterial pollution on the cultivation of bean sprouts and utensils. Each time the bean sprouts are out of the tank, clean the containers and utensils with clean water and use them after sun sterilization. If there is any phenomenon of rotten buds, use lime water to disinfect the containers and tools.
Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
