title: The effect of salt, extract of kinnow and pomegranate fruit by-products on colour and oxidative stability of raw chicken patties during refrigerated storage.
abstract: Use of extracts of kinnow and pomegranate by-products as source of natural antioxidant in salted chicken patties during refrigerated storage was evaluated. Five treatments viz., I. Control (meat), II.MS (meat + 2%salt), III. KRP (meat + 2% salt + 2% kinnow-rind-powder extract), IV. PRP (meat + 2% salt + 2% pomegranate-rind-powder extract), and V. PSP (meat + 2% salt + 2% pomegranate seed powder extract). Results showed that salt significantly (P < 0.05) reduced lightness and yellowness but increased chroma and TBARS values. The average increase in TBARS was significantly (P < 0.05) higher in MS (114%) and Control (108%) but lower in KRP (90%), PRP (81%) and PSP (73%). Lipid oxidation (TBARS) in salted meat during the storage was significantly reduced (P < 0.05) by KRP (39%), PRP (43%) and PSP (68%). Thus it was observed that addition of 2% salt accelerated the TBARS formation but inclusion of extracts of pomegranate and kinnow fruit by-products effectively counteracted this effect. The overall antioxidant effect was in the order of PSP>PRP>KRP. Further a significant (P < 0.05) negative correlation between total phenolics contents and TBARS values was also observed. Therefore, it was concluded that extracts of these fruit by-products have potential to be used as natural antioxidants to minimize the oxidative problems in poultry meat products.
