Introduced by Nicolas Appert and Clarence Birdseye to the world, commercially processed foods undergo different processes in the labs to increase the shelf life of the food. Here are some of the processes processsed food items undergo.
Remove them from the boiling water immediately, and place them in an ice bath to cool them. Remove the vegetables from the ice bath as soon as they cool down. These vegetables can now be used for cooking in any way you like. This type of processing improves the taste of the vegetables.
As soon as the food and jars are cooled, the jars are sealed. Mostly, preservatives are not added to the canned food. The shelf-life of food increases due to canning. Meat, poultry, seafood, pickled vegetables, and fruits are some of the foodstuffs generally available in canned forms.
Drying foodstuffs help retain vitamin A, carbohydrates, and fiber. The caloric value remains the same, but the fat content decreases. The only disadvantage processing food by the drying method is that the water-soluble vitamins like vitamin C are lost in the process of dehydration.
French scientist Louis Pasteur introduced the technique of pasteurization. Pasteurization is used for processing milk. Milk is heated at 72 degree Celsius for 15 minutes. The pasteurization process is not intended to kill all the micro-organisms; instead it preserves some useful microorganisms.
The pasteurization process is not intended to kill all the micro-organisms; instead it preserves some useful microorganisms. Grains, vegetables, fruits, and nuts are irradiated with high-energy radiations for sterilizing purposes.
