GONG Hui,LI Yong (Tongshan Quality & Technology Inspection Station,Xuzhou,Jiangsu,221116; Xuzhou Engineering Institute,Xuzhou,Jiangsu,221008)  
Many producing approaches to yeast essence are introduced.The highly active dry yeast is used as the raw material,after a whole process of expansion raise,separation,dry,autolysins,and compounding,then yeast essence is produced.The influence of temperature,time,the amount of added water and pH degree to the autolyzing technique are studied.The mixing and compounding technique of yeast essence is also discussed.The purified technique for the content of amino nitrogen and the optimal formula for yeast essence,namely the optimal autolysins conditions for the dry yeast cell are worked out as the followings: temperature is 50 ℃,time is 36h,the volume of added water is 1:9 and pH degree is 6 ~ 7.The optimal compounds are as the followings: 5g yeast essence,7g maltodextrin,1g salt,0.14g monosodium glutamate,beef extract 0.1g and 5 drops of beef essence.
