摘要：本論文主要研究了泔水油的提取方法以及泔水轉化為乙醇的發酵條件。實驗通過對所采集的泔水成分進行了分析，對泔水油回收工藝以及糖化時間進行了研究，探討了發酵培養基原料配比、泔水去油、添加纖維素酶、接種量對發酵得到的酒精度的影響，并進行了放大實驗。結果表明：泔水加熱到100℃, 4000轉離心25分鐘提取的油脂量最大，油脂抽取率達到91.18%，最佳糖化時間為35分鐘，原料配比為：玉米粉28g,泔水25g,水47ml時酒精產量最高，酒精含量達到9.1%，去油后酒精產量增加，酒精含量達到10.37%，在纖維素酶添加量為0.05%時酒精產量最高，酒精含量達到10.77%，接種量為12%時酒精產量最高，酒精含量達到13.07%，放大實驗效果最佳，酒精產量達到12.2%。

A study on the re-use of food waste
Abstract: This paper studied the food waste oil extraction methods, as well as food waste into the initial conditions of ethanol fermentation. This project collected through food waste composition analysis of food waste oil recovery process as well as the time for the glycosylation study on the fermentation medium ratio of raw materials, to swill oil, add cellulase, inoculum for the fermentation of alcohol has been the impact of, and conducted experiments to enlarge. The results showed that: food waste heated to 100 ℃, 4000 centrifuge for 25 minutes to make the largest amount of oil, grease extraction rate of 91.18 %, the best saccharification time of 35 minutes, the ratio of raw materials as follows: corn flour 28g, swill 25g, when the water 47ml the highest yield of alcohol, alcohol content 9.1%, to increase oil output after the alcohol, the alcohol content reached 10.37 %, its adding in the 0.05% cellulose ethanol production when the highest alcohol content reached 10.77%, against 12% of alcohol production of the highest alcohol content reached 13.07 %, the best zoom in Experiment 1, alcohol production reached 12.2%.
