Moist heat sterilization

Moist heat sterilization is a method of killing microorganisms and pathogens using heated steam. The process is carried out by filling a space with steam at a set temperature and pressure. In sake production, it is used to sterilize ingredients, tools, and equipment. Because the steam is used at its working temperature, it can effectively remove active yeasts and bacteria, which helps improve the safety and quality of the product. It is regarded as an important means of maintaining a cleaner environment in sake brewing.
