Processing food is the process of turning raw ingredients into food. The procedure uses clean crops or animal products to create long-lasting, generally marketable products. In reality, food processing has existed since prehistoric times. Up before the invention of canning, the typical methods of food preservation were massacring, stirring, and swabbing. The late nineteenth century saw the emergence of ultramodern food processing. Artificial sweeteners, preservatives, snap drying, and canning were all developed. Convenience foods gained popularity in the 20th century. Foods that resembled television feasts were readily accessible at all supermarkets.
