This study was performed to evaluate of active biodegradable packaging applied to lowsodium beef burgers stored at -18oC for 120 days. It was tested four treatments: Beef burgers with 25% (B25) and 50% (B50) of sodium reduction and biodegradable packaging and burgers packed in a biodegradable packaging with 1% oregano essential oil and 25 (BO25) and 50% (BO50) of reduction of sodium. The composition of packaging did not influence the moisture, crude protein, total fat, ash, cooking loss and water activity. The active packaging of oregano oil showed higher color protection in burgers during the storage period. The texture showed a small variation (5-10%) between packagings at day 1, stabilizing in the other periods until the storage end. The burger samples with 25% reduction in sodium and packaging with 1% oregano essential oil (B25) had better taste and aroma, getting a acceptability index above 80% for both periods (30 and 120 days). The use of 1% of oregano essential oil incorporated into packaging reduced lipid oxidation of burgers analyzed in 14% when compared packaging without adding oregano. Microbiological analyzes were maintained stable during the entire storage. Thus, active packaging with oregano essential oil can maintain the quality of beef burger without interfering with their physical and chemical characteristics and improve their sensory attributes during 120 days of storage.
