Abstract: The stability of flavouring emulsion is enhanced by addition of gelatin, a coating material.The factors of affecting the stability of flavoring emulsion included the emulsification temperature, the concentrations of emulsifier and gelatin, and etc.The results of orthogonal experiment showed that the optimum conditions of stable emulsion were as follows:the concentration of emulsifier was 0.3%~0.4%, the concentration of gelatin was 4.0%~5.0%, and the emulsification temperature was 60℃.
