The objectives of this study were to optimization of the aqueous two-phase extraction (ATPE) process of anthocyanin from RPF and microencapsulation of anthocyanin-rich RPF extract. The optimal ATPE conditions were as follows: 0% HCl, 30% ethanol, 19% ammonium sulfate, and liquid to solid ratio 51.71, 97.71 min, and 30 degrees C extraction temperature. Predicted anthocyanin yield at the optimum conditions was 1578.90 mg cyanidin 3-glucoside equivalent/100 g dry fruit. ATPE resulting in 1.80-fold increase in the purity of anthocyanins when compared to conventional solvent extraction (CSE). The composition of the anthocyanins were determined with HPLC-QTOF-MS. Freeze-drying and spray-drying methods were employed for the production of microencapsulated anthocyanin pigments. The half times of microencapsulated anthocyanins at 4, 25 and 37 degrees C were determined as 12.16, 6.60 and 3.12months for freeze-dried microcapsules, and 16.50, 9.24 and 4.29 months for spray-driedmicrocapsules, respectively.WALTER DE GRUYTER GMBH2020-09Articlehttps://rdlopen.rawdatalibrary.net/r/gumushane/15848https://doi.org/10.1515/ijfe-2020-00572194-5764enINTERNATIONAL JOURNAL OF FOOD ENGINEERINGinfo:eu-repo/semantics/closedAccessinfo:eu-repo/semantics/articlehttps://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/15848
