Lesson 04: Principles and Methods of Food Preservation

Introduction

Food preservation is one of the oldest technologies used by the mankind. The perishable foods like fruits, vegetables, milk, meat and fish etc. deteriorate or decay easily, so considerable amounts of such commodities are wasted in various stages of food supply chain unless special methods are applied for their preservation. Preservation of food involves the processes in which, the perishable food materials are given a suitable physical or chemical treatment to prevent their spoilage and to retain their nutritive value for long periods.
