| Abstract: | Objective]The research aimed to study the fermentation conditions of Aspergillus-type Douchi melanoidin.Method]The effects of fermentation temperature,salt content,Fe3+ content on the fermentation of Aspergillus-type Douchi melanoidin were investigated by one-factor experiment and orthogonal test.Result]The results of one-factor experiments showed that under the conditions of 55 ℃,salt content of 10%,Fe3+ content of 0.10%,the intensity of brown stain was highest.The orthogonal test results showed that the best fermentation conditions of Aspergillus-type Douchi melanoidin was: temperature 55 ℃,content of salt 8%,additive content of Fe3+ 0.2%.Conclusion]The fermentation conditions of Aspergillus-type Douchi melanoidin were established.And this result provided scientific references for the formation of melanoidin during the process of fermentation. |
