Technique of ethanol production fermented with raw litch residue by uniform design
In this paper, the technologies of ethanol production fermented from litch residue were discussed using uniform design and the optimization parameters of alcoholic fermentation as the index of alcoholic productive rate were studied. The results showed that the initial concentration of saccharification liquid is 16 °Bx, the alcoholic additive is 0.5%, the fermentation temperature is 36 ℃, and the best fermentation time is 168 h, and the alcoholic productive rate could reach 10.8% under the best optimization parameters by uniform design.
