Comparison of the energy consumption and composition between uncooked and traditional acorn starch alcoholic fermentation

The alcohol conversion rate, energy consumption and composition of alcoholic fermentation were studied between uncooked and cooked acorn starch. The results showed that the alcohol fermentation conversion rate of the two materials has no significant difference (P >0.05), but the uncooked acorn starch fermentation eliminated the process of cooking, liquefaction and saccharification, thus reducing energy consumption. Take 50g acorns as raw materials to be processed into ethanol with these two methods. The results showed that compared with traditional fermentation, the uncooked fermentation technology saved energy 182.215KJ. HPLC and GC-MS chromatogram showed that the amount of alcohol produced by the two methods is close, but alcohol produced by the uncooked one has higher quality.
