Are frozen food safe to eat ?
In food industry there are two process mechanical and cryogenic
In mechanical freezing 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 refrigerates 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 and freezing temperature ,however some frozen foods may contain stabilizer and trans-fat, which is harmful
