Nutritional value of bean sprouts

Bean sprouts are rich in food fiber. Eating more bean sprouts helps to moisturize the intestines and eliminate stools.

Cause analysis and control of rotten bean sprouts

Rotten bean sprouts are mainly caused by bacterial infection, and the reasons are analyzed as follows:

1. The bean seed itself carries the pathogen.

2. The containers and utensils containing bean sprouts are not strictly sterilized.

3. The temperature is too high or too low

4. Untimely watering and unclean water quality

5. Air pollution.

Prevention and control of rotten bean sprouts:

1. Selected bean seeds: select full-grained bean seeds, and carefully remove diseased grains, shrunken grains, tender grains and broken grains before soaking seeds. Then wash the seeds with 0% bleach solution and 5% lime water. Hot water can also be used to blanch seeds, which is helpful to the disinfection and sterilization of bean seed surface. At the same time, it can promote the enzyme activity of bean seeds, increase the germination rate and reduce the incidence of disease.

2. Bean utensils are strictly disinfected: except for keeping them clean, containers and utensils producing bean sprouts should be strictly disinfected before use. Generally, they can be washed and disinfected with 0% bleach powder or 5% alum solution, or they can be burned with torches several times to kill attached pathogens. If conditions permit, a 40-watt ultraviolet germicidal lamp should be installed in the plant.

3. Control the temperature: the suitable temperature for the growth of bean sprouts is 20 ℃. In the process of production, the room temperature must be adjusted to this temperature to make the bean sprouts grow rapidly in the suitable temperature and reduce the occurrence of rotten buds.

4. Clean water quality: it is recommended to use well water or stream water, and it is forbidden to use unclean pond water and big river water. Because there is no pollution in well water and stream water, and it is warm in winter and cool in summer, it plays a good role in promoting the growth of bean sprouts and preventing bean sprouts from overheating. Water should be drenched regularly and quantitatively, usually every 6 hours, so that the waste after metabolism of bean sprouts can be washed away with the current.

5. Drug prevention and treatment: in the early stage of bean sprout disease, a small packet of "8503" is sprayed with 2kg of water, once every 4 hours, which can inhibit the spread of bacteria. Or spray with EJ- 2 disinfectant diluted 200times.
