DEVELOPMENT OF ZEIN-CASEIN MICROCAPSULES FOR ENCAPSULATION OF MINT ESSENTIAL OIL

In this study, the efficiency and release properties of microcapsules obtained by coating zein-casein complex at different ratios of mint essential oil have been investigated. Efficiency and release levels of mint essential oil coated with zein and essential oils coated with zein-casein complex were compared. It is planned to increase their activity by encapsulating the mint essential oil in the apolar structure in capsule form by the hydrophilic / hydrophobic properties which arise from the zein and its amino acids. In this study, casein additions of 1%, 3%, 5%, 7%, 9%, 11%, 13% and 15% were applied to the zein coating material for mint essential oil microcapsulation. The efficiency of microencapsulation with only zein as the coating material was determined to be 46%, while the activity value of microencapsulated with 13% with casein-zein formulation was determined at 54.66 %. In addition, in the release rate test, the release of mint essential oil from the microcapsules was completed by providing 42.75% release over 9 days
