| 摘 要： | 为了挤压膨化甘薯酒精发酵应用于工业生产提供理论依据。利用挤压膨化甘薯粉为原料，研究料水比、糖化酶添加量、酵母接种量等基本因素对挤压膨化甘薯酒精发酵的影响。得出最佳工艺：料水比1:2、糖化酶用量130 U/g、酵母接种量为0.1%。在此条件下，30℃发酵72 h，发酵醪酒精度为14.43%，与传统发酵工艺相比，发酵醪酒精度提高了21.7%。

Study on No Cooking No Saccharifying Producing Alcohol of Extruded Sweet Potato |
| |
| Abstract: | Substituted extrusion process for traditional cooking and liquefaction and saccharifying process of alcohol production with sweet potato was studied in this paper. The optimal technological conditions through single factor experiment were obtained ,it was showed as follows: the ratio of starch to water as 1 : 2, saccharifying enzyme 130 U / g, yeast inoculation quantity as 0.1﹪. Under the conditions, fermentation at 30℃ for 72 h, the alcohol content of fermentation mash was 14.43% (v / v). Comparing with traditional fermentation technology, the alcohol content of fermentation mash increased by 21.7 % (v / v). |
