The cold chain is essential to ensure food preservation. If the cold chain is not followed correctly, it would not be possible to transport fresh and frozen food over long distances.
A cold chain thermometer is indispensable to keep the cold chain unbroken from the moment food is obtained to the moment it is delivered to the end consumer. Only with proper temperature control can we ensure its compliance.
Therefore, the cold chain is the guarantee of good food preservation, be it a piece of meat or fresh vegetables. You need to know how it works and the regulations that apply in Spain so that you can understand it in depth.
Types of Cold chain
Fresh food, not frozen, requires temperatures that do not exceed 7 °C. This way, microorganisms go into a dormant stage and the enzymes that break down the food slow down their activity.
In this case, a specific vehicle is also required to maintain a stable temperature and airflow that ensures even distribution.
The most significant risk in these cases is the change in temperature depending on the loading area. It would be useless if one part of the compartment was at 7 °C and the rest of it was at 10 °C. Since they are physically stuck to the products, temperature labels can easily alert of the risk and prevent the deterioration of the goods.
This procedure is the one that guarantees a more extended preservation period. However, in some cases, the product may lose its properties. In the process of freezing food, temperatures range from below 0 °C and to −18 °C. This ensures that the enzymes that break down the food slow down or halt their activity, killing the vast majority of the microorganisms.However, this preservation method requires transport and storage facilities that are equipped to provide suitable temperature conditions. Having a reliable solution for temperature control is also important to guarantee that the food cold chain has not been broken at any time and ensure the food’s preservation.
