The aims of the work were: to investigate the effect of chicken strain on chemical composition and colour parameters of fresh breast muscle; to evaluate the results obtained using different illuminants (A, C and F); to verify the possibility of predicting some meat features by near infrared reflectance spectroscopy (NIRS) of freeze-dried breast muscle. The trial was carried out on 39 chicken broilers from three strains, differing in body size, slaughtered at 30 days of age. Fresh breast samples were different only in ash content (P<0.01). Illuminant effect was highly significant for all colour variables, depending on the major wavelength characteristics of each illuminant. Significant differences among strains were detected in redness values. The NIRS technique was very accurate to predict fat content of muscle (R(2)c=0.98, SEC=0.20). These findings may have practical importance to improve instrumental procedures for on-line evaluation of poultry meat quality.
研究鸡的品种对新鲜胸肌化学成分和颜色参数的影响；评估使用不同光源（A、C和F）所获得的结果；通过对冻干胸肌进行近红外反射光谱（NIRS）分析来验证预测某些肉质特征的可能性。试验选用了39只30日龄屠宰的来自三个品种、体型不同的肉鸡。新鲜胸肌样本仅在灰分含量上存在差异（P<0.01）。光源对所有颜色变量的影响非常显著，这取决于每种光源的主要波长特性。在红色值方面检测到不同品种之间存在显著差异。NIRS技术在预测肌肉脂肪含量方面非常准确（R(2)c=0.98，SEC=0.20）。这些发现对于改进禽肉品质在线评估的仪器方法可能具有实际意义。
