Sub topic 1

Meaning of processing and products

Animal products refers to things or materials produced or obtained from farm animals for the purpose of human needs. Processing of animal products is an organized series of actions that produces the desired animal product. Processing of animal products is important because all the products from the animal cannot be consumed raw. Processing of animal products improves their nutritional quality and also elongates their shelf life, thereby giving room for their transportation from points of production to any part of the world where they may be needed.

Animal products

Animal products can be grouped into two:

  1. Primary products: These are products derived from the animal and consumed directly with little or no processing e.g. eggs, meat, milk, etc.
  2. Secondary products: These are products derived from primary products which are converted to other products e.g. egg powder, milk powder, whey, burger, burger etc.
