Stabilita termica dell'acido ascorbico e dell'eritorbato di sodio

In some processing industries thermal treatments of thermal unstable substances are performed, with important implications for the quality of products. In these processes the design of plants must include constraints to operating variables to account for these phenomena on the basis of the theory of thermal stability. For example, in the processing of sodium erythorbate and ascorbic acid these facts are particularly important due to easy decomposition of the high value added product and strict quality requirements of food applications. Studies of decomposition of the products by DSC can be useful to identify reaction and kinetics parameters and relate them to the main parameters influencing thermal processes.
