Diet supplementation (DS) (100, 200, 300ppm vitamin E -VE; 150ppm product rich in flavonoids-PRF; 100+100ppm VE-PRF; no supplementation) effect was evaluated on lamb quality throughout 10days after sampling (preservation time: PT). pH, colour, myoglobin forms and lipid oxidation were analyzed on Longissimus muscle. Trained panellists evaluated colour intensity of chops packaged in modified atmosphere under display up to 12days. PT had a larger effect on quality than DS. DS showed a clear antioxidant effect on lipids, especially at long PT and at high doses of VE. Visual test showed statistical differences among DS from day 4 of display where 200 and 300ppm VE improved visual colour score. In general, supplementation with antioxidants showed better meat quality and diets higher than 100ppm VE showed higher antioxidant capacity than the rest. The PRF diet was similar for a short PT but lower at a long PT. More research on flavonoids is necessary.
在采样后的10天内（保存时间：PT），评估了日粮补充剂（DS）（100、200、300ppm维生素E - VE；150ppm富含类黄酮的产品 - PRF；100 + 100ppm VE - PRF；无补充剂）对羊肉品质的影响。对背最长肌进行了pH值、颜色、肌红蛋白形式和脂质氧化分析。经过培训的评审员对在改良气氛下包装展示长达12天的排骨颜色强度进行了评估。PT对品质的影响大于DS。DS对脂质具有明显的抗氧化作用，尤其是在较长的PT和高剂量VE时。视觉测试显示，从展示第4天起，不同DS之间存在统计学差异，其中200和300ppm VE改善了视觉颜色评分。总体而言，补充抗氧化剂显示出更好的肉质，高于100ppm VE的日粮比其他日粮显示出更高的抗氧化能力。PRF日粮在短PT时相似，但在长PT时较低。有必要对类黄酮进行更多研究。
