摘要
将三维荧光光谱技术、小波压缩和交替惩罚三线性分解算法(APTLD)结合,提出了一种鉴别掺伪芝麻油的新方法。利用荧光光谱仪测量纯芝麻油及掺伪芝麻油样本的三维荧光光谱,通过激发校正和发射校正消除仪器带来的误差,得到样本的真实三维荧光光谱数据;利用小波压缩对处理后的真实数据进行压缩,以减少冗余信息,其中压缩分数和数据恢复分数分别大于94.00%和98.00%;利用APTLD算法对压缩后的数据进行定性及定量分析,得到的回收率为97.0%~99.8%,预测方均根误差不大于0.120。研究结果表明,所提方法能够准确鉴别纯芝麻油及掺伪芝麻油样本,并对其组分含量进行预测。
Abstract
A new method for identification of adulterated sesame oil is proposed, and the method combines three-dimensional fluorescence spectroscopy with wavelet compression and alternating penalty trilinear decomposition (APTLD) algorithms. The three-dimensional fluorescence spectra of pure sesame oil and adulterated sesame oil samples are measured with fluorescence spectrometer, and the error caused by the instrument is eliminated via excitation correction and emission correction, then the true three-dimensional fluorescence spectrum data of the samples are obtained. Wavelet compression is used to compress the processed real data to reduce redundant information. The compression fraction and data recovery fraction are greater than 94.00% and 98.00%, respectively. The APTLD algorithm is used to qualitatively and quantitatively analyze the compressed three-dimensional fluorescence spectral data. The obtained recovery rate is 97.0%-99.8%, and the root mean square error of prediction (RMSEP) is not larger than 0.120. The research results show that the proposed method can accurately identify the pure sesame oil and the adulterated sesame oil samples, and predict the component of the samples.
