The drying is an essential step to ensure the storage of this by-product at an industrial level, in order to use it as a functional ingredient or as a nutraceutical. Thus, this research focuses on the evaluation of the effect of the convective air-drying process in orange by-products at three different temperatures (40, 60 and 80 C) and air flows (0, 0.8 and 1.6 m/s) on the phenolic content (measured by HPLC-MS), the antioxidant activity (measured by DPPH, ABTS and FRAP), and the vitamin C content (measured by HPLC-UV/VIS). Moreover, the mathematical modelling of its drying kinetics was carried out to examine the orange by-product behavior. Among the tested mathematical models, the Page model reported the highest fit and the best drying conditions, which showed the lowest reductions were at 60 C with an air flow of 1.6 m/s and taking 315 min.}, organization = {Proyectos I+D+i del Programa Operativo FEDER 2020 B-AGR-506-UGR20}, publisher = {MDPI}, keywords = {HPLC-MS}, keywords = {Orange peel}, keywords = {Vitamin C}, keywords = {Air-drying}, keywords = {Polyphenols}, keywords = {Hesperidin}, title = {Mathematical Modelling of Convective Drying of Orange By-Product and Its Influence on Phenolic Compounds and Ascorbic Acid Content, and Its Antioxidant Activity}, doi = {10.3390/foods12030500}, author = {Razola Díaz, María del Carmen and Verardo, Vito and Gómez Caravaca, Ana María and García Villanova Ruiz, Belén and Guerra Hernández, Eduardo Jesús}, }
