摘　　要：[目的]研究优化橡子粉发酵乙醇的试验条件。[方法]以采于牡丹江林口的橡子为原料,以乙醇浓度为指标,通过单因素和正交试验考察发酵时间、接种量、转速及发酵温度4个因素对橡子粉发酵后乙醇浓度的影响。[结果]试验确定了各因素对原料发酵的影响程度大小依次为:发酵时间、发酵温度、转速、接种量;橡子粉发酵生产乙醇的最佳条件:发酵液接种量3%,摇床转速120 r/min,发酵温度32℃,发酵时间为接种培养开始至96 h结束,此条件下橡子粉的酒精转化率约为16.37%。[结论]研究可为橡子原料量化生产燃料乙醇奠定基础。[Objective] To optimize experimental conditions of ethanol fermentation by acorn powder. [Method] With acorn collected from Linkou,Mudanjiang as raw material,ethanol concentration as indicator,through single factor and orthogonal test,the effects of fermentation time,inoculation amount,rotation speed and fermentation temperature on ethanol concentration were investigated. [Result] The order of influence factors is： fermentation time,fermentation temperature,rotation speed,inoculation amount; the optimal conditions ethanol fermentation by acorn powder are： fermentation broth 3%,shaking speed 120 r / min,fermentation temperature 32 ℃,fermentation time 96 h,under the above conditions,alcohol conversion rate of acorn powder is about 16. 37%. [Conclusion]The research can lay the foundation for the production of fuel ethanol with acorn.
