Isoconversional analysis and accurate determination of lifetime properties for thermal and thermo-oxidative degradation processes of Aronia melanocarpa were examined. The Sestak-Berggren (SB) autocatalytic model was found as best model to describe degradation process of A. melanocarpa in inert atmosphere. It has been found that autocatalysis may occur from inevitable presence of water probably through the hydrolysis. In the case of thermo-oxidative degradation, it was found that main mechanistic scheme can be presented with two different forms of reaction mechanism function, such as nth-order reaction model (with n GT 1) and SB autocatalytic model. It was determined that neochlorogenic acid represents main compound, which has a strong hydrogen-donating activity. Based on lifetime analysis, it was found that in oxidative conditions, A. melanocarpa shows greater resistance to temperature variations, which correspond to storage conditions and where degradation mechanism greatly affects st...ability and physico-chemical characteristics of its constituents. Industrial relevance: Current research has a direct industrial application during the testing of responses of blade chokeberry-A. melanocarpa fresh samples on the various thermal stresses in the inert and oxidative reaction conditions. Knowledge of the exact mechanism of degradation (referring to precisely defined reaction pathways) of A. melanocarpa in different reaction atmospheres enables us the targeting an exactly isolated chemical compounds in A. melanocarpa fresh samples, which are responsible for antioxidant protection of human tissue and plasma. The results presented in this paper can be guidelines for the application of industrial processes for precise allocations of these compounds and their further testing for the treatment of malignant diseases. The importance of this research also comes down to the fact that 25% of total polyphenols in chokeberry fruits are anthocyanins, which represent the powerful antioxidants in vitro. Also, the current work provides a specific approach in accurate determination of lifetime properties of A. melanocarpa samples, which is very important in terms of checking the behavior of tested fruit berry system on the temperature variations during storage periods.
