摘　　要：探究了近红外光谱法快速测定调味料酒中酒精度含量的方法。采用基于近红外光谱技术的酒精分析仪,以料酒为研究对象,确定近红外光谱法的可行性。分别采用该方法与酒精计法对料酒的酒精度进行测定,为降低两种方法间的偏差,建立了近红外光谱法测定料酒酒精度的快速定量模型,成品样品采用修正系数0.9744进行校正,半成品样品依据仪器示值结果,无需校正。研究结果表明,模型的测定结果很好,具有较高的精密度和稳定性。近红外光谱法可用于检测料酒酒精度,为料酒酒精度的测定提供了快速检测方法。The rapid determination of alcohol content in condiment liquor by near infrared spectroscopy was studied. The feasibility of this method was determined by using alcohol analyzer based on near infrared spectroscopy and taking cooking wine as the research object. In order to reduce the deviation between the two methods, a fast quantitative model for the determination of alcohol content in cooking wine by near infrared spectroscopy was established. The correction coefficient was 0.974 4 for the finished sample, and no correction was needed for the semi-finished sample according to the results of the instrument. The results show that the model has good accuracy and stability. Near infrared spectroscopy (NIRS) can be used to detect the alcohol content of cooking wine, which provides a rapid method for the determination of alcohol content of cooking wine.
