Are Frozen foods Safe to eat? | #aumsum

In food industry, there are two processes used for freezing, mechanical and cryogenic. In mechanical freezing, chilled air is passed over food items, causing them to slowly cool down and freeze. While, in cryogenic or flash freezing, food items are either directly sprayed or immersed in refrigerants like liquid nitrogen or carbon dioxide, thus freezing the food instantly.

Frozen foods do have certain advantages. Firstly, nutritional loss is almost negligible. Secondly, while transporting and storing fresh food items, harmful bacteria can grow and contaminate the food. However, this will not happen in case of frozen foods because bacteria don’t usually grow in low, freezing temperatures. However, some frozen foods may contain stabilizers and trans-fat. It is believed that these additives will either increase the risk or worsen certain preexisting health conditions.
