Biology · Food Preservation Principles

Assertion (A): Refrigeration is one of the most widely adopted preservation techniques in households and food industries because it effectively slows down microbial growth without drastically altering the natural taste, texture, and nutritional composition of food. Reason (R): At lower temperatures, the metabolic activities of microorganisms and the catalytic efficiency of enzymes involved in spoilage reactions are significantly reduced, thereby delaying deterioration.
