Using this technique has spawned an industry of foods and frozen entrees. Techniques Foods naturally contain a large amount of water (80 to 90%). The freezing technique lowers the temperature slowly (up to 24 hours) thus transforming this cold water into ice crystals. These crystals eventually perforate the cell wall of food, thus altering their texture but the flavor (evaporation of water and aroma volatile production by micro-organisms to toxic substances, changes related to enzymatic and non enzymatic ...). Freezing is an industrial technique that is suddenly cool (a few minutes to an hour) of foods by exposing them intensely at temperatures ranging from -35 ° C to 196 ° C. Through this process, water contained in cells crystallizes finely limiting tissue destruction. The products thus treated retain their texture, flavor and can be kept longer . There are several methods of freezing, include mainly: * The technical contact, only for foods low thickness is achieved by introducing a food between two plates in which circulates a fluid at -35 ° C; Once frozen, the products must be stored at or below -18 ° C. |
