Food processing is the transformation of raw ingredients into food products that can be eaten by physical or chemical means. Food preservation slows or stops food spoilage
Decomposition
Decomposition is the process by which organic substances are broken down into a much simpler form of matter. The process is essential for recycling the finite matter that occupies physical space in the biome. Bodies of living organisms begin to decompose shortly after death. Animals…

What is Food processing?
Food Processing is the process of transforming food items into a form that can be used. It can cover the processing of raw materials into food via different physical and chemical processes. Various activities covered in this process are mincing, cooking, canning, liquefaction, pickling, macerating and emulsification.
Why is food processing important?
The important benefits of food processing include: Food processing reduces the number of harmful bacteria in food that can cause diseases. For eg., drying, pickling dehydrates the food product and alters the pH that prevents the growth of harmful microorganisms. It also improves the shelf-life of food products.
What are the benefits of food technology?
Food technology is a very vast domain concerning with the production and processing of food. Food processing has certain objectives, such as: 1 It boosts the shelf life of food products. 2 Prevent food-contamination. 3 Food storage and Transportation. 4 Turns raw food materials into attractive, marketable products. 5 Provide employment to a large population.
How can microorganisms be destroyed?
The majority of microorganisms and spores could be destroyed by applying sufficient heat to food items. One of the known examples includes boiling of milk.
How does preserving food work?
It is a technique of preserving food by slowing down the growth of microorganisms and action of an enzyme that is responsible for the rotting of food. Some of the food products such as meat, dairy products, and fish could be stored in a refrigerator thus increasing the shelf-life of the products.
How to decompose food?
Exposure of food particles to sunlight to dry them is one such method done naturally. This process would result in the evaporation of moisture content from food, thus preventing microorganisms from invading the food. Moisture from food could also be removed by using hot air
What are the objectives of food processing?
Food processing has certain objectives, such as: It boosts the shelf life of food products. Prevent food-contamination. Food storage and Transportation.
