    Abstract:
    The effect of vacuum packaging and pomegranate peel extract on ground goat meat and cooked nuggets during refrigerated storage (4 ± 1 °C) was evaluated. Three different treatments evaluated were: I). Aerobic packaging (AP); II) Vacuum packaging (VP) and III). Vacuum packaging along with 1 % pomegranate peel extract (VP + PPE). Results of quality evaluation showed that VP and VP + PPE maintained a more stable colour than AP. In all treatments, a significant (P < 0.05) increase in hardness and gumminess of nuggets was observed during the storage. But, VP nuggets showed minimum changes in texture parameters. TBARS values were significantly (P < 0.05) lower in VP and VP + PPE than AP. In ground meat, VP reduced the TBARS by 27 % and PPE reduced the TBARS by 41 %. In nuggets, TBARS was decreased by 17 % and 40 % in VP and VP + PPE respectively. Total plate counts were significantly higher (>log 7) in AP than VP meat and nuggets. Thus VP and PPE have a synergistic antioxidant effect and VP extended the refrigerated shelf life of goat meat and nuggets.
