ABSTRACT:
Indonesia is the largest palm oil producer
in the world. The content of β-carotene in palm oil, which can act as
pro-vitamin A, is relatively high, so it has great potential for overcoming
cases of vitamin A deficiency. 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 of microencapsulation used in this study, namely coacervation,
thin-layer drying, and SiO2 absorption technique, which theoretically are
suitable for encapsulating β-carotene in palm oil. The aim of this research is
to compare and find the most suitable method of microencapsulation process of
palm oil to obtain the highest β-carotene content and retention. Results show
that those three methods are significantly different in affecting water
absorption, solubility in water, yield, microencapsulation efficiency, β-carotene
content, and retention of microencapsulated palm oil. The microencapsulated
palm oil made from thin layer drying method has the highest β-carotene content
at 200.16 μg/g and β-carotene retention of 68.89%. It also has low water
absorption and high water solubility, so it can be applied as a powder premix
in food as vitamin A supplement.
