| 摘 要： | 以225个猪肉肉糜样本为研究对象,利用可见/近红外光谱分析技术对猪肉肉糜主要品质指标的的快速检测进行了研究.光谱经小波去噪后,采用偏最小二乘法和支持向量机定量分析方法分别建立了肉糜中肌内脂肪、蛋白质和水分含量的可见/近红外光谱预测模型.其中,肌内脂肪的支持向量机定量预测模型最优,校正相关系数rcal和预测相关系数rva...

| Abstract: | The objective of the present study was to estimate minced pork meat quality using visible and near infrared(Vis-NIR) spectroscopy.Two hundred twenty five carcasses samples from longissimus dorsi muscle were scanned over the Vis-NIR spectral range from 350 to 1 015 nm and analysed for intramuscular fat(IMF),protein and moisture according to the official methods.Wavelet transform was employed to eliminate the spectra noise.Partial least square regression(PLSR) and support vector machine(SVM) were used to deve... |
