The effects of three concentrations (1, 2 and 3%) of lentil coat powder (LCP) on physicochemical properties, lipid stability and sensory characteristics of beef burgers were investigated after 0, 3, 6, 9 and 12 days of cold storage at 4 ± 1ºC. Burgers containing LCP had lower levels of moisture, protein, fat and pH, but they had higher levels of ash, carbohydrates, total phenolic compounds (TPC), antioxidant activity and water holding capacity (WHC) when compared with the control and BHT/BHA samples. Also, the addition of LCP retarded lipid oxidation by decreasing of TBARS values that improved the oxidative stability of burger samples. The efficiency of LCP to retard lipid oxidation was concentration-dependent. Moreover, LCP decreased L*, a* and b* values of beef burgers. Lentil coat powder improved sensory characteristics during the cold storage, and the samples containing (1% and 2%) levels of LCP had the best quality.
