摘要
对橡实淀粉酒精生料发酵法和传统酒精发酵法的酒精转化率、能耗和发酵醪液的组成成分进行比较研究。结果表明:生料发酵法与传统发酵法在酒精转化率方面没有显著性差异(P>0.05),但生料发酵省去了蒸煮、液化和糖化等几道工序,减少了能耗。以50 g橡实为原料加工成酒精,生料发酵法比传统发酵法节省热能消耗182.215 kJ。HPLC及GC-MS色谱显示,生料发酵法与传统发酵法相比,两者所产酒精量接近,但酒精质量更高。
The alcohol conversion rate, energy consumption and the composition of alcoholic fermentation liquid of uncooked and cooked acorn starch were investigated. The results showed that： the alcohol fermentation conversion rates of the two materials were not significantly different （ P 〉 0.05 ） , and the uncooked acorn starch fermentation eliminated the need for cooking, liquefaction and saccharification, reducing energy consumption. Processing 50 g acorns into ethanol saved 182. 215 kJ compared with the whole process of fermentation process. HPLC and GC-MS chromatogram showed that the uncooked fermentation method, compared with the traditional fermentation method, produced a similar amount of alcohol, but its quality was higher.
