Tracing Change: The Indian Food Processing Industry 

Food processing helps extend the shelf life of food and makes raw food easier to consume over time. Food processing units were born from the need to ensure that seasonal and easily perishable food did not get wasted and that food was available for consumption for extended periods of time. Historically, food has been preserved by fermentation, drying in the sun, brining and so on. Modern food processing industries use advanced technologies and practices.
