There Are Several Common Disinfection Methods

1. Pasteurization
At temperatures ranging from 60 to 66 ℃, most nutritional bacteria can be killed, such as the post fermentation process of Agaricus bisporus culture material, which can kill harmful miscellaneous bacteria and pests.
2. Boiling water disinfection
Mainly used for disinfection of metal tools, needle cartridges, etc. Boiling in boiling water for 20-30 minutes can kill the Trophosome of microorganisms, while cell spores can be killed in 1-2 hours. If a small amount of 2% to 5% carbonate solution is added to water, the disinfection time can be greatly shortened; Adding 1% sodium bicarbonate can increase the boiling point of water, accelerate spore death, and prevent metal instruments from rusting due to cooking.
3. Drying and disinfection
Using substances to dry microorganisms to achieve sterilization or antibacterial purposes. Microbial cells contain 70% to 90% water, and after losing water, microorganisms tend to die. People often use this characteristic to preserve food (such as dried shiitake mushrooms, agaric), pharmaceuticals, etc. for a longer period of time.
4. Osmotic pressure disinfection
The method of sterilization or bacteriostasis with high or low Osmotic pressure is called Osmotic pressure disinfection. The usual concentration of salt solution is around 20%, and the concentration of sugar solution is between 50% and 70%.
