中文摘要:

      目的 开发基于可见/近红外光谱技术的牛肉品质快速检测系统。方法 利用波长范围为400~2600 nm的光谱仪为核心检测部件, 结合控制器、光源、光纤等辅助装置构成了检测系统的硬件部分, 对32个牛肉通脊样本进行检测, 并用肉类嫩度仪进行验证。结果 27个样本为嫩肉, 5个样本为粗糙肉, 嫩度检测正确率为100%。结论 该装置能够对牛肉的嫩度品质进行较准确的检测。

英文摘要:

      Objective To develop a rapid detection system of beef quality based on near-infrared reflectance spectroscopy(NIRS). Methods The spectrometer with the wavelength from 400 nm to 2600 nm as core component, controller, light source, and fiber were main parts of the detection device, which was used for detection of 32 samples of beef longissimus. The results were verified by meat tenderness instrument. Results A total of 27 samples of beef longissimus were tender meat and other 5 samples were rough meat. The accuracy rate was 100%. Conclusion The beef quality can be detected accurately by the detection device.
