What is the difference between heat sterilization and non-heat sterilization?

Based on the standards regulated in the Food Sanitation Law, heat sterilization is done by heating at 85 degrees for 30 minutes or more, and it is a method of sterilizing by adding heat quantity equal to or more than that. On the other hand, unheated sterilization uses filtration over several layers of filters to remove the bacteria, instead of sterilizing natural water by overheating. It is important that non-heat sterilization is done in clean production conditions. The way of actual processing varies from manufacturer to manufacturer.
