Forty young crossbred bulls (10 ± 2.2 months of age; 219 ± 11.7 kg) were finished in a feedlot with one of five different treatments: CON, control (no essential oil); CLO450, clove essential oil (450 mg/kg); CLO880, clove essential oil (880 mg/kg); CIN450; cinnamon essential oil (450 mg/kg); and CIN880, cinnamon essential oil (880 mg/kg). Instrumental meat quality attributes and consumer acceptability aspects (visual and sensory) were assessed during meat ageing and display. The inclusion of clove essential oil showed (P = 0.033) a quadratic effect on lipid oxidation in meat evaluated under display conditions. Level of cinnamon essential oil affected (P < 0.05) pH, shear force, and meat colour. On the other hand, the diet had no effect (P > 0.05) on sensory or visual acceptability. Ageing (7 days) enhanced (P < 0.05) sensory acceptability attributes. Globally, the addition of essential oil in bull diets can be an alternative to reduces lipid oxidation without modifying sensory acceptability attributes.
四十头杂交公牛(10±2.2 月龄;219±11.7kg)在一个饲养场中用五种不同的处理方式进行育肥:CON,对照组(无精油);CLO450,丁香精油(450mg/kg);CLO880,丁香精油(880mg/kg);CIN450,肉桂精油(450mg/kg);和 CIN880,肉桂精油(880mg/kg)。在肉品陈化和展示过程中,评估了仪器测定的肉品质量特性和消费者可接受性方面(视觉和感官)。在展示条件下,丁香精油的添加表现出(P=0.033)对肉品脂质氧化的二次效应。肉桂精油的水平影响(P<0.05)pH 值、剪切力和肉色。另一方面,饮食对感官或视觉可接受性没有影响(P>0.05)。陈化(7 天)增强了(P<0.05)感官可接受性属性。总体而言,在公牛日粮中添加精油可以作为一种替代方法,降低脂质氧化而不改变感官可接受性属性。
