Abstract

It is aimed to achieve the optimized for vitamin E (dl-α-tocopherol acetate) micro-encapsulation through complex coacervation at high efficiency with this study. The response surface methodology (RSM) was used to optimize the microencapsulation state of vitamin E. The microencapsulation efficiency of microencapsulated tocopherol was investigated in terms of two variables including amount of core material (vitamin E) and concentration of surfactant (SDS). According to the RSM results, the sample with the highest response response (93,42%), 4 g core material, and 0,5% surfactant sample was found in the experiment set. Microcapsules were morphologically characterized by optical microscopy, scanning electron microscopy (SEM) and fourier transformation infrared spectroscopy (FT-IR). This analysis performed to clarify the microencapsulation and examine the microcapsule structure chemically.
