| Abstract: | Objective] To provide the theoretic basis for application of the extrusion puff technology to cassava fuel alcohol production.Method] The cassava after extrusion puff was used for alcoholic fermentation.The optimal technological conditions were obtained through L18(38) orthogonal experiment.Result] The result showed that the alcohol content of fermentation mash was 16.61 %(V/V)under the optimal conditions of the ratio of starch and water of 1∶2,saccharification amylase amount of 100 U/g,the saccharificafion temperature of 60 ℃,the saccharificafion time of 45 min,yeast inoculation quantity of 0.1% and the fermentation temperature of 30 ℃.Under this conditions,comparing with the traditional fermentation technology,the alcohol content of fermentation mash increased by 22.76 %.Conclusion] The combination of extrusion puff technology with the highly concentration alcohol fermentation technology may advance the large-scale development of the cassava fuel alcohol profession. |
