在 brojler 料中用玉米取代小麦会使肉的颜色变黑,增加黄色. 基于玉米的饮食减少了体区域的颜色差异,特别是当皮肤完好无损时.
科学领域:
- 动物科学动物科学
- 禽类营养 养 禽类营养
- 食品科学 食品科学 食品科学
背景情况:
- 饮食成分显著影响肉肉的质量.
- 了解颜色分布对于肉尸体的评估至关重要.
- 谷物成分,如玉米与小麦相比,可以影响肉的颜色.
研究的目的:
- 评估用玉米取代小麦对 brojler 尸体颜色分布的影响.
- 为了确定受食玉米纳入影响的特定尸体区域.
- 为了评估玉米对肉色参数的影响 (CIEL*a*b*空间).
主要方法:
- 一千二百只ROSS 308只雄被以玉米或小麦为基础的饮食.
- 在屠宰后的24小时内,对每次处理的15个尸体进行了颜色测量.
- 一个MINOLTA CM600d色谱仪被用来测量12个尸体位置的颜色.
主要成果:
- 肉尸体的颜色分布不均,在皮肤和皮肤脱落区域之间存在显著差异.
- 与以小麦为基础的饮食相比,以玉米为基础的饮食导致肉类更深 (增加L*) 和更高的黄色 (增加a*).
- 玉米的含有减少了尸体区域的颜色变化,特别是当皮肤存在时,并减少了树颜色差异.
结论:
- 食玉米影响肉肉的颜色,导致与小麦相比,肉类更深,更黄色.
- 皮肤在同质化尸体颜色方面发挥着作用,掩盖了一些区域差异.
- Hue°可能表明由于饮食变化而引起的乳房颜色变化,这表明其作为质量指标的潜力.
