This study was designed to investigate the effect of alpha lipoic acid (ALA) and alpha tocopherol acetate (ATA) on the antioxidant potential, lipid stability and the quality of the broiler breast meat and meat products. The treatment plan was as (T1=control feed, T2=200 mg ATA + 25 mg ALA/kg feed, T3=200 mg ATA + 75 mg ALA/kg feed, T4=200 mg ATA +150 mg ALA/kg feed, T5=Oxidized oil (4%), T6=200 mg ATA + 150 mg ALA + Oxidized oil (4%)/kg feed). After two weeks of acclimatization the birds were fed with ALA and ATA enriched diet. The results revealed that maximum deposition of ALA took place in T4 which contain maximum dose of ALA. The TBARS and DPPH values of the broiler breast meat were in T4 (0.14 ± 0.01 MDA/kg of meat, 76.69 ± 0.14%) and in T5 were (0.24 ± 0.15 MDA/Kg of meat, 44.98 ± 0.04%) accordingly. ATA concentration were also highest in T4 (206.43 ± 0.22 mg/g of meat) and lowest in T5 (79.09 ± 0.06 mg/g of meat). Sensory evaluation results showed that nuggets and patties made of T5 containing oxidized oil were least liked and T4 got highest score. In a nutshell, 150 mg/kg feed dietary supplementation of ALA with constant level of ATA can ameliorate the antioxidant potential, lipid stability and nutritional qualities of broiler breast meat and meat products.
本研究旨在探讨α-硫辛酸（ALA）和醋酸生育酚（ATA）对肉鸡胸肉和肉产品的抗氧化潜力、脂质稳定性和品质的影响。处理方案如下（T1=对照饲料，T2=200mg ATA+25mg ALA/kg 饲料，T3=200mg ATA+75mg ALA/kg 饲料，T4=200mg ATA+150mg ALA/kg 饲料，T5=氧化油（4%），T6=200mg ATA+150mg ALA+氧化油（4%）/kg 饲料）。经过两周的适应期，鸟类开始喂食富含 ALA 和 ATA 的饮食。结果表明，T4 中 ALA 的沉积量最大，其中含有最大剂量的 ALA。肉鸡胸肉的 TBARS 和 DPPH 值在 T4（0.14±0.01MDA/kg 肉，76.69±0.14%）和 T5（0.24±0.15MDA/kg 肉，44.98±0.04%）中达到最高。ATA 浓度在 T4 中也最高（206.43±0.22mg/g 肉），在 T5 中最低（79.09±0.06mg/g 肉）。感官评价结果表明，含有氧化油的 T5 制成的鸡块和肉饼最不受欢迎，而 T4 得分最高。总之，150mg/kg 饲料中添加 ALA 可以改善肉鸡胸肉和肉产品的抗氧化潜力、脂质稳定性和营养价值。
