Stability of Mixture Honey, Black Seed Oil and Olive Oil with Tween 80 as Emulsifier

Abstract

The purpose of this study to view stability a mixture of honey, black seed oil, and olive oil. There have many benefits and widely distributed in the market. However, this mixture has instability problem because it has different properties of polarity or phase, to solve this problem required emulsifier Tween 80, an emulsifier food grade to stabilize the mixture. This research is expected to be aimed for mixture with the addition of the emulsifier. In the addition of 1.25 grams, Tween 80 could mix up to 7.5% of the total oil in the mixture. Those are showing the process of the distribution particle, viscosity measurement, phase separation by centrifugation and storage for eight weeks in room temperature.
