Are Frozen foods Safe to eat?

In the 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, the 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 the 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 can either increase the risk. Or worsen certain preexisting health conditions.
