Low temperature slows down the chemical reactions and any remaining microbial activity that can occur in dried foods, helping them maintain quality and extend shelf life. Even when moisture is minimal, heat can accelerate oxidation, off-flavors, and nutrient loss, so cooler storage slows those processes. In contrast, a moist environment invites rehydration and microbial growth, bright light can degrade vitamins and fats, and an oxygen-rich atmosphere speeds up oxidation. Keeping dehydrated products cool thus remains beneficial for preserving shelf life.
