Answer 2

Short Answer: Nitrogen is used in the food packaging industry because it preserves freshness, protects the nutrients, and prevents aerobic microbial growth.

Answer:

Using nitrogen gas to purge food packaging of oxygen is a safe practice widely used throughout the food industry. Another reason that nitrogen gas is often used for food packaging is to provide a pressurized atmosphere that prevents package collapse.Because it is a safe, inert gas, nitrogen is an excellent replacement for oxygen or supplemental gas in food packaging and manufacturing. Increased nitrogen preserves freshness, protects the nutrients, and prevents aerobic microbial growth.

Explanation:

Nitrogen packing requires the use of high concentrations of gaseous nitrogen within food packaging. Nitrogen at 99.0% concentration is usually recommended for food preservation. Other chemical conditions that contribute to effective nitrogen packaging are:

• Oxygen concentration should be maintained under 1%

• Carbon monoxide and carbon dioxide concentrations in the air mixture below 10ppm and 300ppm respectively.

• Moisture concentrations should remain below 55.8ppm

Why Nitrogen Is Used in Food Packaging

Gaseous nitrogen has unique chemical and physical properties that make it suitable for use in food processing. Nitrogen is inert which means it will not react with prepared food materials, which can alter their aromas or flavors. Also, gaseous nitrogen will effectively displace oxygen minimizing oxidation and the growth of microorganisms that cause foods to lose their freshness and deteriorate faster.
