The aim of this study was to assess the effectiveness of calcium alginate edible films incorporated with Terminalia arjuna on the lipid oxidative stability and storage quality of chevon sausages. Chevon sausages were aerobically packaged in the edible films containing different concentrations of T. arjuna viz. T1 (0.0%), T2 (0.50%) and T3 (1.0%) and were stored under refrigerated (4±1 °C) conditions. A significant improvement was observed in the lipid oxidative stability and microbial quality of the products. Products packaged in T2 and T3 films exhibited significantly (P < 0.05) lower values for TBARS (mg malonaldehyde/kg), microbial counts (log cfu/g) and FFA (% oleic acid). Higher (P < 0.05) sensory scores were also observed for the products packaged in T2 and T3 films. This study shows that application of a bioactive edible film incorporated with T. arjuna is an effective strategy in retarding the lipid oxidation and storage changes in meat products.

The study was conducted to explore the possibility of utilization of Terminalia arjuna as a novel natural preservative in meat products by using chevon sausages as a model system. Chevon sausages were prepared by incorporating different levels of T. arjuna viz. T1 (0.25%), T2 (0.50%) and T3 (0.75%) and were assessed for various lipid oxidative stability and storage quality parameters under refrigerated (4 ± 1 °C) conditions. T. arjuna showed a significant (p < 0.05) effect on the lipid oxidative stability as the treated products exhibited significantly (p < 0.05) lower TBARS (mg malonaldehyde/kg) values in comparison to control. A significant (p < 0.05) effect was also observed on the microbial stability as T. arjuna incorporated products showed significantly (p < 0.05) lower values for total plate count (log cfu/g), psychrophilic count (log cfu/g), yeast and mould count (log cfu/g) and FFA (% oleic acid) values. Significantly (p < 0.05) higher scores were observed for various sensory parameters of the products incorporated with T. arjuna during refrigerated storage. T. arjuna successfully improved the lipid oxidative stability and storage quality of the model meat product and may be commercially exploited as a novel preservative in muscle foods.
