Frozen food is a low-temperature product made from fresh raw materials, properly processed and rapidly frozen, and delivered to the consumer location under continuous low temperature conditions ranging from -18 ℃ to -20 ℃. The biggest advantage of frozen food is that it preserves its original quality at low temperatures without the use of any preservatives or additives, but its nutritional value cannot be compared to fresh fish, meat, etc.
