Enhancement of lipid stability of broiler breast meat and meat products fed on alpha lipoic acid and alpha tocopherol acetate supplemented feed

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 (T-1 = control feed, T-2 = 200 mg ATA + 25 mg ALA/kg feed, T-3 = 200 mg ATA + 75 mg ALA/kg feed, T-4 = 200 mg ATA + 150 mg ALA/kg feed, T-5 = Oxidized oil (4%), T-6 = 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 T-4 which contain maximum dose of ALA. The TBARS and DPPH values of the broiler breast meat were in T-4 (0.14 +/- 0.01 MDA/kg of meat, 76.69 +/- 0.14%) and in T-5 were (0.24 +/- 0.15 MDA/Kg of meat, 44.98 +/- 0.04%) accordingly. ATA concentration were also highest in T-4 (206.43 +/- 0.22 mg/g of meat) and lowest in T-5 (79.09 +/- 0.06 mg/g of meat). Sensory evaluation results showed that nuggets and patties made of T-5 containing oxidized oil were least liked and T-4 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.
