As far as frozen food is concerned, cold chain must guarantee that products are always kept on a temperature below -18°C, from the production plant to the consumer. In cold storage the temperature is always below -30°C: the lower the temperature, the better the preservation of products.
The most difficult part of the cold chain is the distribution to the sales points: during loading and unloading, products are inevitably at room temperature, but the mass is so cold that it contrasts the increase in temperature. Do you know which is the cold chain’s weakest link? The last step: when frozen products are brought home.
Nowadays consumers pay more attention than in the past, but it is still unusual to carry home frozen foods using thermal bags. This is something never to forget.
