Food Processing & Preservation Definition is the process of treating and handling food to stop or slow down spoilage thus allowing longer storage, it is also a way of converting perishable produce into a stable form so that it can be stored and brought to the market all year round.
Why is it necessary to process and preserve? Extends the availability of agricultural produce Provides better storability and transportability Retains the products nutritive value & palatability
Transforms the produce into a new or more usable forms which offer more convenience to consumers Increases profitability of the products specially when raw agricultural produce may not fetch the right market price
Methods of Processing & Preservation Drying One of the most ancient food preservation techniques which reduces water or moisture content of the food to prevent or delay growth of microorganism.
Refrigeration and Freezing Preserves food by slowing down the growth and reproduction of microorganisms and the action of enzymes which cause food to rot, in this process temperature is controlled to preserve the foods.
Fermentation A process which preserves food through conversion of carbohydrates to alcohols and carbon dioxide using bacteria, yeast or combination of both. It usually implies that the action of the microorganism is desirable.
Pickling One of the fermentation process which is relatively low cost method of preservation.
