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.
