Are frozen foods safe to eat?

Introduction:-

In food industry,there are two processes used for freezing, mechanical and cryogenic.

Mechanical freezing:-
In mechanical freezing,chilled air is passed over the food items causing them to slowly down and freeze.

Cryogenic freezing:-
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 advantage:-

1. Nutritional loss is almost negligible
2 .While transporing 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.

Negative side:-

However some frozen foods contains stabilizers and trans fat . It is believed that these additives can either increase the risk or worsen certain pre-existing health conditions
