Abstract

Vitamin C is one of common bioactive compound widely known and used by many people, especially in Indonesia. The weakness of vitamin C stablity are sensitive with extreme pH, temperature, oxygen and direct light. Because of that, the encapsulation of itamin C with W1/O/W2 emulsion can be the solution for maintaining the stability of vitamin C. This study is aimed to emulsify Vitamin C in the inner aqueous phase of water-in-oil-water (W1/O/W2) emulsions with soybean oil as the oil phase. Two type of emulsifier Tween 80 and WPC-Pectin in the outer aqueous phase used to compare their stability during storage. The result of this research showed that emulsion with WPC-Pectin had bigger droplet size 1.34 μm than emulsion with tween 80 0.91 μm. Tween 80 had a better stability with 14.41% of creming index compared to WPC-Pectin with 23.06% of creaming index. Morphology of W1/O/W2 emulsion with Tween 80 can be described as W1/O/W2 when emulsion with WPC Pectin cannot be described as W1/O/W2 Emulsion. Tween 80 is a better emulsifier than WPC-Pectin to stabilized the W1/O/W2 emulsion in the outer aqueous phase.
