采用近红外光谱分析技术对不同地区、不同品种的101份花生样品进行图谱分析,研究了花生水分、脂肪和蛋白含量的快速测定方法。结果表明:花生水分湿基含量分布为4.01%~10.93%,脂肪湿基含量为40.84%~62.81%,蛋白质湿基含量为22.47%~29.67%,分布梯度广,具有很好的代表性。建立了定标模型,为花生整粒的快速评价建立便捷的方法。 Near infrared spectroscopy was used to analyze 101 peanut samples from different regions and different varieties. The rapid determination of moisture, fat and protein content in peanut was studied. The results showed that the wet basis content of peanut was 4.01% -10.93%, the wet basis content of peanut was 40.84% ​​-62.81%, the content of wet basis of protein was 22.47% -29.67%, the distribution gradient was wide, and had good representativeness. A calibration model was established to establish a convenient method for the rapid evaluation of peanut wholegrain.
