HOW IT WORKS Slows down microbial division (Psycrophile) Osmosis!!!!!! Removal of oxygen kills pathogens using heat 75C kills pathogens using heat 100C+ Changing composition of air alters biological processes See Vacuum packing Toxins introduced to kill microbes Osmosis!!!!!! pH is unfavourable for enzymatic action Toxins introduced to kill microbes
