| 摘 要： | 利用傅里叶变换近红外光谱技术建立猪肉、牛肉和羊肉的定性识别模型。用主成分分析法将原始数据压缩为10 个主成分，在全波段9 881.46～4 119.20 cm－1范围内，利用附加散射校正技术结合Savitzky-Golay滤波法对光谱数据进行预处理，采用判别分析法建立模型。模型对训练集的识别准确率为100%，对预测集猪肉、牛肉和羊肉的识别准确率分别为99.28%、97.42%和100%。结果表明：近红外光谱结合模式识别方法能快速无损地识别猪肉、牛肉和羊肉。

| Abstract: | A qualitative identification model for pork, beef and mutton was established by Fourier transform near-infrared
spectroscopy (NIR). The raw data were compressed to 10 principal components using principal component analysis. The
spectral data were preprocessed by additional scattering correction combined with Savitzky-Golayfilter method in the range
of 9 881.46–4 119.20 cm-1. The model was established using discriminant analysis. Identification accuracy rate of the model
for training set was 100%. Identification accuracy rates of pork, beef and mutton for prediction set were 99.28%, 97.42% and
100%, respectively. These results showed that pork, beef and mutton could be rapidly and non-destructively identified by
near-infrared spectroscopy combined with pattern recognition method. |
