    摘要:

    提出一种应用近红外光谱技术对野生蘑菇识别的新方法。使用FieldSpec3便携式近红外光谱仪对包括野生蘑菇在内的13种蘑菇进行漫反射光谱采集,通过对光谱的分析,得出1 483,1 727,1 930,2 100,2 180,2 310 nm为样品中多糖、蛋白质、脂肪的特征吸收峰,且野生蘑菇中3种成分的相关基团近红外特征吸收峰显著地高于其它蘑菇。将以上6处波长的吸光率作为输入变量,建立支持向量机识别模型,取RBF核,优化后惩罚因子C=2 048.0,核参数γ=0.031 25,该模型对未知样本正确识别率为95.3%。结果表明,利用近红外光谱少量波长处的特征吸收差异,建立支持向量机识别模型可以很好地对野生蘑菇进行鉴别。

    Abstract:

    A new method for discrimination of wild Mushroom by means of near infrared spectroscopy (NIRS) was established. Visible and near infrared reflectance spectra of 13 different types of mushroom including 3 wild mushrooms were collected with a portable near infrared spectrometer ( ASD Fieldspec3 ). Based on the analysis of spectrum, are the characteristics absorption peaks of polysaccharides, protein, fat of the mushroom are1 483, 1 727, 1 930, 2 100, 2 180, 2 310 nm, which of wild mushroom in are significantly higher than other mushrooms. With these 6 wavelengths of absorbance as input variables to establish recognition model of support vector machine, which takes RBF kernel, the parameters of C = 2 048.0, gamma = 0.031 25, the model for unknown sample recognition correct was 95.3%. Results show that, using the mushroom sample in a few wavelengths of near infrared spectral characteristics of absorption, establish support vector machine recognition model can be identified very well.
