鱼粉中肉骨粉的可见-近红外光谱快速定性判别方法（简报）

为了能更加快速准确的定性判别鱼粉中是否掺有肉骨粉（MBM），该文收集中国常用的鱼粉和肉骨粉，制备定标集样品201个，其中111个为掺有不同肉骨粉质量分数（1%～33%）的样品，90个为纯鱼粉，并独立制备113个验证集样品，其中74个为掺有不同肉骨粉质量分数（1%～33%）的样品，39个为纯鱼粉。在400～2 498 nm波长范围内进行光谱扫描，选择合适的光谱预处理方法和光谱范围，采用DPLS方法建立判别分析模型。建立的判别分析模型：数学预处理方法为2-8-6-1，散射校正方法为变量标准化处理（SNV），光谱范围为全谱（408～ 2 492 nm），定标模型的正确判断率为95.7%，外部验证正确判断率为95.6%，对于掺入量≥5%MBM时，正确判断率为100%。研究结果证明近红外反射光谱可以提供一种快速鉴别鱼粉中MBM的方法。

Rapidly qualitative discrimination of meat and bone meal in fishmeal by visible and near infrared reflectance spectroscopy

In order to rapidly and accurately discriminate whether fishmeal was adulterated with meat and bone meal(MBM)or not,representative fishmeal and MBM samples were collected in China.201 calibration samples were prepared,including 111 samples adulterated with MBM(1%-33%)and 90 pure fishmeal samples.113 external validation samples were prepared independently,including 74 samples adulterated with MBM(1%-33%)and 39 pure fishmeal samples.The spectra were scanned from 400 nm to 2 498 nm.The effects of spectrum pret...
