Description
Traditional preservation methods like pickling and curing use salt, acid, and temperature to inhibit spoilage.
Technical
Pickling relies on osmotic dehydration and acidification to lower water activity (a_w) and pH, creating an environment hostile to Clostridium botulinum and other spoilage organisms. Curing introduces salt and nitrite, which reduce a_w, form nitrosylhemochrome for color stability, and inhibit bacterial growth through both osmotic and chemical mechanisms. Both processes depend on precise temperature control to balance microbial safety with sensory quality.
