Patent

CA 2691585

The invention relates to a process for roasting and surface pasteurization of particulate food products. The roasting and surface pasteurization can be combined and united to form one process, if, according to the invention, it is provided that a treatment is carried out in a moist atmosphere at temperatures > 100°C, that the pasteurization treatment is carried out in a roasting system during the roasting operation, that during the pasteurization phase the temperature of the product surface is held a few degrees below the dew point temperature of the atmosphere which is established, that the pasteurization is performed for 1 - 30 min, and that with advancing or continued roasting the water of condensation on the surface of the food products is removed and the water uptake of the same is minimized.

L'invention concerne un procédé de grillage et de pasteurisation en surface de produits alimentaires en particules. Le grillage et la pasteurisation en surface peuvent être combinés et réunis en un seul procédé si, selon l'invention, on prévoit de réaliser un traitement dans une atmosphère humide à une température > 100°C, en réalisant le traitement de pasteurisation dans un système de grillage pendant l'opération de grillage, en maintenant pendant la phase de pasteurisation la température de la surface du produit à quelques degrés en dessous de la température du point de rosée de l'atmosphère que l'on a établie, en réalisant la pasteurisation pendant 1 à 30 min et en retirant l'eau de condensation présente à la surface des produits alimentaires pendant la poursuite ou le prolongement du grillage pour ainsi minimiser l'absorption d'eau par ces produits.
