Food preservation is the practice of extending the shelf life and maintaining the quality of food by inhibiting microbial growth and delaying natural enzymatic and chemical reactions. Various techniques such as heat treatment, refrigeration, and the use of preservatives like organic acids are employed to achieve this. These methods not only prevent spoilage but also ensure that nutritional content, flavor, and texture are preserved. With increasing consumer demand for minimally processed and preservative-free foods, modern food preservation focuses on innovative approaches that enhance safety and extend shelf life without compromising product quality.
