Abstract: A process for surface pasteurization/sterilization of particulate food products. Water uptake and qualitative changes of food products are minimized and pasteurization or sterilization conditions are optimized when food products are used preheated, wherein product temperature is selected a few degrees below the evaporation temperature of the pasteurization/sterilization system, in that the preheating temperature of food products is selected lower than the saturated steam temperature, preferably a few degrees below the saturated steam temperature at a predetermined pressure, in that treatment is performed in a moist, air-free atmosphere, wherein pasteurization occurs at temperatures between 55 and 99° C. at a low pasteurization pressure, or sterilization occurs at temperatures between 100° C. and 140° C.

Abstract: The disclosure 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 wherein 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.

Abstract: The method for pasteurisation and/or sterilisation of a food according to the invention comprises, in a first step, provision of a device (1) for the impingement of steam, particularly water vapour, on a food. The food is then impinged upon with steam for the pasteurisation and/or sterilisation of the food by means of the steam in order to achieve a reduction in the quantity of a microorganism present on and/or in the food, particularly a pathogenic microorganism. Before the food is impinged upon with steam, the temperature of the food is brought to a preheating temperature greater than or equal to the pasteurisation and/or sterilisation temperature.

Abstract: 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.
