What are methods for packaging the meat?
- Simple
- Vacuum
- Modified atmosphere packaging (MAP)
What can you tell about wrapping and packaging of meat?

- Expiration date
- Price
What are the simple packaging methods used and its qualities?
Foils, bags without air drainage (does not extend shelf life)
What are the vacuum packaging methods used and it’s qualities?
Plastic foils while aspirating air (prolongs shelf life, can effect color and give sour odour due to bacteria)
What are the modified atmosphere packaging?
CO2 30%, Oxygen 5%, Nitrogen 64%.
CO2 - inhibitory effect on microbial growth and oxidation processes.
What are the two packaging material types?
Natural casings
Artificial casings
