摘　　要：根据老白干香型发酵酒醅中水分、酸度、淀粉、还原糖和酒精度指标的数值范围,按照工艺类型和发酵阶段进行分类,建立近红外光谱定量检测模型。通过验证发现模型的准确度和精密度良好,均满足模型建立要求。According to the numerical ranges of moisture, acidity, starch, reducing sugar and alcohol content in the fermented grains of Laobaigan Baijiu, the fermented grains were classified by technology type and fermentation stage, and the quantitative detection models by near-infrared spectroscopy were established. Through verification, it was found that the accuracy and precision of the models were good, and met the requirements for model construction.
