摘要：
A method for thermally treating a product in order to have the product obtain the desired product properties, comprising the following steps: (a) determining the water activity value which, for carrying out the thermal treatment, is required to have the product obtain the desired properties； (b) contacting the product with water vapor, at an increased temperature and an associated saturated vapor pressure (p*), while the temperature on the surface of the product is 80-260° C.； (c) setting a vapor pressure (p) in step (b) such that p/p* is equal to the water activity value determined in step (a)； and (d) maintaining for a time duration (t) the process conditions mentioned in steps (b) and (c) for obtaining the product with the desired product properties.
