Résumé

For rapid chilling fresh products we propose the immersion in melting carbon dioxide hydrate crystals, produced at +8°C and 30 bar. We compare the chilling time of a specific fresh product from 30 to 4°C making use of a “shock freezer” (2 m/s air velocity, air at -10°C) and applying a slurry of CO2 hydrate crystals. Furthermore the effect of these two methods on the weight loss of the product is compared. Then the chilling of chicken products through the proposed method is experimentally verified, including microbiologic contamination of samples chilled through high-speed dry air, immersion in melting water and immersion in CO2 hydrate slurry. Finally the economic advantages and practical applicability of the proposed method are evaluated.
