摘　　要：应用近红外光谱技术(NIRS),对木薯乙醇发酵液中乙醇、甘油及葡萄糖这3种成分进行定标模型的开发,优化其数学模型,比较NIR法与HPLC法的差异。结果表明,近红外光谱法可以对木薯发酵过程中产生的乙醇、甘油及葡萄糖进行快速,准确的在线检测。Near Infrared Reflectance Spectroscopy was applied for monitoring the process of cassava alcohol fermentation especially in the measurement of alcohol, glycerol and glucose. Qualitative models were developed and optimized, data obtained based on the new models were compared with HPLC method. It indicated that NIR technique can be used in rapid and accurate monitoring of three contents during the process of cassava fermentation.
