Abstract： Sufu is mixed fermented with the ratio of Geotrichum candidum to Mucor nidicola of 2：1 In view of the post fermentation period of sufu，the changes of physicochemical properties and flavor substances are investigated. The results show that the total acid content increases rapidly during 4～ 6 weeks of post fermentation，reaching 1.148g/100g at the 9th week of post fermentation. At the 3rd week of post fermentation，the protein content increases rapidly. At the 9th week of post fermentation，the content of water-soluble protein reaches 21.05g/100g ，and the content of amino acid nitrogen reaches （20 1.293g/100g ，The total free amino acid content of sufu at the beginning of post fermentation is 1.388mg/g and it increases rapidly at the 9th week of post fermentation，reaching 22.272mg/g ，among which，the content of aspartic acid and glutamic acid presenting umami increases obviously， giving umami and sweetness to sufu. The content of alcohols increases significantly，accounting for 56.18% ，and the content of esters also increases，accounting for 10.73% ，which gives a unique aroma to sufu， thus improving the quality of sufu.
