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

Abstract

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=200mg ATA+25mg ALA/kg feed, T3=200mg ATA+75mg ALA/kg feed, T4=200mg ATA+150mg ALA/kg feed, T5=Oxidized oil (4%), T6=200mg ATA+150mg 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 T 4 (0.140.01 MDA/kg of meat, 76.690.14%) and in T5 were (0.240.15 MDA/Kg of meat, 44.980.04%) accordingly. ATA concentration were also highest in T4 (206.430.22mg/g of meat) and lowest in T5 (79.090.06mg/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, 150mg/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. © 2012 Sohaib et al.; licensee BioMed Central Ltd.
