Abstract
A method for preparing stable liquid emulsion forms of plant extract is provided. A plant extract having a bitter flavor is mixed with diluent oil as an oil mixture and heat is applied to the oil mixture. An emulsifying agent is dispersed in water as an emulsifying solution. The oil mixture is mixed with the emulsifying solution. The mixed oil mixture and emulsifying solution is homogenized as a liquid form of the plant extract. Gluconic acid is added to the liquid form of the plant extract. The bitter flavor of the plant extract is disguised by adding a bitter blocker to the liquid form of the plant extract.
