In this study, high efficiency vitamin E microencapsulation was aimed with the complex coacervation method. Response surface methodology (RSM) was used to optimize the microencapsulation efficiency of vitamin E. The microencapsulation efficiency of microencapsulated vitamin E was investigated in terms of two variables, including the amount of core material and surfactant concentration (SDS). According to the RSM results, the experimental condition with the highest efficiency (93.42%) was found in 4.00 g of core material and 0.50% surfactant in the experiment set. Morphological and chemical analyzes of microcapsules were characterized by optical microscopy and scanning electron microscopy (SEM) and Fourier transformation infrared spectroscopy (FT-IR).

Several methods are published for the coating of solid particles and liquid in recent years. The microencapsulation process is also included in these methods. Microencapsulation is a process by which droplets or particles of liquid or solid material are coated with a film of polymeric material. Microencapsulation technology is widely applied in pharmaceutical, food, agricultural pesticide, cosmetic, textile and other related fields. In this study, tocopherol (vitamin E) microcapsules were formed by complex coacervation method using gelatin and gum arabic polymer mixtures. To form the emulsion as a surfactant and the microcapsule wall to impart insolubility property as crosslinker was used. The effects of the parameters such as polymer ratio, surfactant quantity, cross-linker quantity on microencapsulation were investigated. Microcapsules morfology was characterized by scanning electron microscopy (SEM). Fourier transformation infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), high performance liquid chromotography (HPLC) analysis were carried out to explain the microcapsulation mechanism and investigate the microcapsule structure chemically.

In our study, encapsulation was performed with complex coacervation method in an experimental set created with Karabas herb oil response surface methodology (RSM). The experiment set was created by entering three independent variables (core material amount, surfactant concentration, stirring speed) in RSM. The encapsulation efficiency (EV%) was calculated from the produced samples. The experimental efficiencies found were analyzed by entering RSM as a response response. The model reached as a result of RSM analysis was significant (p <0,05), R² value was 99,15%, and lack-of-fit p value was found as 0,217 (p>0,05). The collected data indicated that three independent variables entered in RSM affect the response response EV%. Samples produced from the experimental set were characterized under optical microscope and scanning electron microscope (SEM). The vast majority of the images obtained were observed in micron (10-6) and a small amount of nano (10-9) in size. It is believed that the study will be an important step in the encapsulation of karabaş herb oil, which has a wide range of economic value, and different application areas. [ABSTRACT FROM AUTHOR]
