What are food additives?

Food additives are substances added to food that are not normally consumed by themselves. 

200

What is the large-scale production system?

large production, may have production lines

200

What points fall under the operation category? Name at least 1

What is food spoilage?


Food spoilage is the process where a food product becomes unsuitable to ingest by the consumer. The cause of such a process is due to many outside factors as a side-effect of the type of product it is, as well as how the product is packaged and stored.

What is temp control in food preservation

prevents the growth of microorganisms by poisoning the bacteria by increasing or decreasing the temp to the point of the bacteria die
