该清馨剂由乙醇、丙二醇、三乙醇胺、三氯羟基二苯醚、联苯苄唑、香精及附加剂所组成，经相应的生产工艺而制成。

PGA and CMC-Na (FH-9) were the chosen stabilizers. Based on the orthogonal experiment,the optimum added amount of stabilizers and homogenizing and sterilization parameters wereobtained. The results indicated that the best formula of this kind of fermented soybean drink withthe greatest stability were: 0.4% of CMC-Na(FH-9),0.2% of PGA, 0.067% of MG and 0.083%ofSE, homogenizing twice under 40℃,30MPa and pasteurizing twice under 80℃ for 20min. Thesensory ,physical, chemical and microorganism target of fermented soybean drink were studiedand conformed to the Chinese Standards.
