Food processing is the transformation of raw ingredients, by physical or chemical means into food, or of food into other forms. Food processing combines raw food ingredients to produce marketable food products that can be easily prepared and served by the consumer.
Food processing typically involves activities such as mincing and macerating, liquefaction, emulsification, and cooking (such as boiling, broiling, frying, or grilling); pickling, pasteurization, and many other kinds of preservation; and canning or other packaging.
(Primary-processing such as dicing or slicing, freezing or drying when leading to secondary products are also included.
The Food Industry is a complex, global collective of diverse businesses that supply most of the food consumed by the world population.
Only subsistence farmers, those who survive on what they grow, and hunter-gatherers can be considered outside of the scope of the modern food industry.
The machine industry or machinery industry is a subsector of the industry, that produces and maintains machines for consumers, the industry, and most other companies in the economy.
This machine industry traditionally belongs to the heavy industry. Nowadays, many smaller companies in this branch are considered part of the light industry. Most manufacturers in the machinery industry are called machine factories.
