食用肉色调的数字化检测

The Examination for the Digital of Meat Color

食肉色调检测的直接法和间接法的基本原理,同时依据CTELAB表色系的色调三维空间理论,通过牛肉检测实例说明食肉色素蛋白质(血红素蛋白质)的诱导体形态变化与生肉反射光谱的关系,生肉的反射光谱与明度、色度(a*、b*)的关系,结果显示a*、b*值与食肉新鲜度成正比关系。

The paper introduced the basic principle of direct method and the indirect method at the meat color examination.Simultaneity introduced the theory of CTELAB color three-dimensional space.Through the example that examine the beef explain that relation of meat＇s pigment（hemoprotein） inducer with the reflectivity spectra of raw,the relation of reflectivity spectra of raw with lightness,chroma（a＊ and b＊）.The resulting display freshness of raw are direct ratio relations with a＊ and b＊ value.
