Drying involves the exposure of farm products to sunlight or heat to reduce the moisture content of the farm produce. Artificial drying can be carried out by using electric ovens.

The aim of drying is to reduce the moisture content of the farm produce and inhibit the activities of micro-organisms.

Examples of livestock production that can be preserved by drying include meat, milk, fish, blood meal, hides and skins, eggs, bone meal, animal droppings, etc.

Examples of crop production that is preserved by drying are locust bean, cowpea, rice, maize, cassava flour, yam flour, plantain, groundnut, melon, pepper, ginger, etc.

It is an efficient and effective method of preserving farm produce in a fresh form for a longer period of time.

The major aim of refrigeration or freezing is to render microorganisms inactive by keeping farm produce in a reduce temperature.

Examples of livestock production that can be refrigerated or frozen are meat, milk, eggs, fish, etc.

Examples of crop produce refrigerated or frozen are fruits such as apple, orange, mango, avocado, watermelon and vegetables such as garden egg, okra, cabbage, pumpkin leaves, etc.

It is the process of adding a substantial quantity of table salt to farm produce to prevent deterioration. The aim of salting is to extract water from the farm produce and create an acidic medium which is harmful to microorganisms.

Examples of livestock production that can be preserved by salting are crayfish, fish, and meat. Examples of crop produce preserved by salting are ground pepper, ground melon, locust beans, etc.

4. Canning

It is the process of enclosing farm produce in tin-plated cans or metal drums with or without preservatives to prolong their shelf lives. Canning is mostly carried out in the industries but some forms of canning of farm produce can be done at home.

The aim of canning is to prevent the supply of oxygen to farm produce and prevent oxidation by microorganisms.

This is done by adding vegetable oil, tomato paste, and ethanol to farm produce in sealed metal containers.

Examples of livestock products that are preserved by canning include evaporated milk, condensed milk, powdered milk, corn beef meat, etc.

Examples of canning are green beans, tomatoes, etc.
