Jams and dried meats do not require refrigeration due to high sugar/salt content inhibiting bacteria growth, low water activity levels, and traditional preservation methods.
Growth of bacteria: Jams and dried meats have high sugar or salt content, creating an environment where water is not easily available for bacterial growth. The lack of water impedes the growth of bacteria.
Low water activity: Jams and dried meats have low water activity levels due to their sugar or salt content, which inhibits microbial growth and prevents spoilage without the need for refrigeration.
Preservation methods: Traditional techniques like dehydration for dried meats and the high sugar content in jams act as preservatives, reducing the need for refrigeration.
