Which of the following methods works primarily by inhibiting microbial growth through low moisture?
Dehydration
Microorganisms such as bacteria, yeasts and moulds need water to grow and multiply. Dehydration (drying) removes most of the moisture from food, so microbes cannot grow and the food keeps for longer.
Refrigeration slows microbial growth mainly by low temperature; canning works by heat sterilisation and sealing in airtight containers; pasteurization uses controlled heating to kill most pathogens.
Hence, the answer is Dehydration.
