Reformulasi Mikroenkapsulasi Minyak Sawit dengan Teknik Koaservasi, Pengeringan Lapis Tipis, dan Penyerapan SiO2

Abstract

Cases of vitamin A deficiency (VAD) are often found in Indonesia. On the other hand, Indonesia is the largest palm oil producer in the world. The content of β-carotene, which is a provitamin A, in palm oil is relatively high, so that it has a great potential for overcoming cases of VAD. By microencapsulation process of palm oil, β-carotene content in palm oil will be more stable and have a longer shelf life. There are three methods used in this study, namely coacervation, thin-layer drying, and SiO2 absorption technique – teoretically they are suitable for encapsulating β-carotene in palm oil. Results of ANOVA test at 5% significance level showed that the differences in methods significantly affect water absorption, solubility in water, yield, efficiency, and the β-carotene content and retention of microencapsulate. The microencapsulate made by thin-layer drying method had the highest levels of β-carotene at 200.16 ppm with retention 68.89%. It also had low water absorption and high water solubility so that it can be applied as a premix.
