The method of freezing food is a method that helps to preserve freshness and to preserve it longer. Freezing is one of the most relevant and important technical measures in the food processing industry.
1.Are nutrients in frozen foods preserved?
Freezing food means quickly cooling food down to -40 degrees C, then freezing it at -18 degrees C. The faster the cooling time, the better, this will help retain more nutrients. more in food.
Fresh food placed in the freezer compartment is called normal or slow freezing. Food takes longer to freeze, sometimes all day long.
The faster the frozen food has to be cooled, the tiny ice crystals in the food will not grow, so when thawed, the loss of nutrients will be less, the quality will be kept like fresh food. than.
If food is refrigerated normally, ice crystals have the conditions to grow. These crystals will have sharp edges that will disrupt cell membranes. Therefore, when thawed, food will lose a lot of nutrients and after processing it will be easy to chew and bland.
2.Fast-frozen foods that contain preservatives:
Quick freezing is to freeze fresh food to extend its shelf life without adding any preservatives.
Rapid cooling can inhibit microbial growth, keep biological enzymes active at low temperatures, effectively inhibit the ability to break down proteins and fats and prevent food spoilage.
3.Convenience during transportation:
During the transport and storage of raw food, harmful bacteria can grow and contaminate the food.
This is not the case with frozen foods, because bacteria cannot thrive at freezing temperatures. Helps keep food fresh and delicious for longer.
