基于三维荧光光谱快速识别冷榨 一级核桃油品牌和产地 Rapid identification of brand and origin of cold pressed first-grade walnut oil based on three-dimensional fluorescence spectroscopy
为寻找一种能快速识别核桃油品牌和产地的方法,以来自4个品牌3个产地的冷榨一级核桃油为研究对象,分批次收集了300个样品,用荧光检测仪进行样品扫描,分两个时间段采集三维荧光光谱,间隔为1个月。对收集的共600组光谱数据运用主成分分析(PCA)进行特征提取,同品牌或同产地的样品分别选取主成分1组成新的数据集,达到数据降维,再结合偏最小二乘判别(PLS-DA)和人工神经网络判别(BP-ANN)化学模式识别方法,对应构建核桃油的品牌识别模型和产地识别模型。结果表明:PLS-DA和BP-ANN对核桃油的品牌和产地的识别率都能达到100%。因此,三维荧光光谱与PLS-DA和BP-ANN方法结合,可用于快速...
