Abstract: Geotrichum candidum Link as the malting additives was studied in the traditional malting process. The diastatic power, α-amino nitrogen ( α-AN ) and extracts were used as objects of the study. The optimistic parameters of malting technology were studied by contrast analysis of single factors and response surface methodology.The results indicated that Geotrichum candidum Link inoculation value of 104 spores per gram, soaking temperature of 15℃ and soaking pH of 4.0 were the optimistic parameters of malting technology. Under these conditions, the anticipant and real synthetical target of malt quality were 205.33 and 206.15 respectively, and the diastatic power, α-AN and extracts of malt was 308.5WK, 186mg /100g and 87.1%.Meanwhile, all the standards were above the standards of light industry, and the mycotoxins were not detected in products.
