Which term describes removing water to extend shelf life?

Removing water from food to slow or prevent spoilage relies on lowering water activity, which many microorganisms need to grow. Dehydration achieves this by drying out moisture through methods like air drying, heat drying, or freeze-drying. With less available water, bacteria, yeasts, and molds can’t multiply as quickly, so shelf life is extended and quality is better preserved. The other terms don’t describe water removal: modified atmosphere packaging changes the gas mix around the product rather than its moisture content; cutting or chopping increases surface area and can speed spoilage if anything, but it doesn’t reduce moisture; sour refers to acidity or fermentation and is not about removing water. Therefore, the term for removing water to extend shelf life is dehydration.
