The Pasteurization process is the method of subjecting liquids to mild heat at a specific temperature and time, and quickly cooling them down again in order to destroy pathogens in your fermented or semi-fermented products. Thus, increasing the shelf life of the manufactured products. Untreated microorganisms may lead to diseases, spoilage, or unwanted fermentation. Most pasteurization equipment operate in a continuous method using plate heat exchangers to keep a uniform level of high efficiency sterilization.
