Abstract: With beer yeast waster as the raw material,the important effect factors such as among ratio of material to water,time,temperature and dosage of acetic acid were confirmed by the single factor tests primarily,then according to the Box-Benhnken center combined experimental design principles,the 3 most important effect factors were analyzed with RSM.The optimum conditions were obtained as follows:ratio of material and water 1:4,temperature 43.6 ℃,dosage of acetic acid 3.5%,and time 5.5 h.Under these conditions,the content of GSH red reach over 29%.

Key words: beer yeast waste, glutathione(GSH), extraction, response surface methodlogy(RSM)
