Antioxidant properties of banana (Musa paradisiaca) and Sapodilla/Chikoo (Manilkara zapota) peel extracts in chicken patties were evaluated. Four treatments viz., I. Control (meat + 2% salt), II.BHT (meat + 2% salt + 0.1% BHT), III. BPE (meat + 2% salt + 2% banana peel extract) and IV. SPE (meat + 2% salt + 2% sapodilla/chikoo peel extract) were compared for changes in colour and lipid oxidation during 8 days refrigerated storage (4 ± °C). The average phenolic content was 550.2 and 550.8 mg gallic acid equivalent per 10 g peel in BPE and SPE respectively. Free radical scavenging activity was 66.9 and 67.8% in BPE and SPE respectively. Banana peel extract had significantly (P < 0.05) higher reducing activity (1.6) as compared to sapodilla peel extract (0.91). During refrigerated storage period, all color parameters decreased significantly in all treatments. Observation on lipid oxidation showed a significantly (P < 0.05) higher TBARS values in control than other three treatments. The increase in TBARS from initial day of storage to last day of storage was highest in control (514.3%) as compared to BHT (387.7%), BPE (370.6%) and SPE (383.7%). Both synthetic antioxidants and natural extracts significantly decreased the TBARS. The average decrease in TBARS values during 8 days of storage was 56.8%, 38.3% and 37.2% values in BHT, BPE and SPE treatments respectively. Therefore, it was concluded that water extracts obtained from banana and sapodilla peels could be explored as natural antioxidants in poultry meat and meat products.
香蕉(Musa paradisiaca)和人心果(Manilkara zapota)皮提取物的抗氧化特性在鸡肉饼中的应用进行了评估。比较了 4 种处理方法:I. 对照(肉+2%盐)、II. BHT(肉+2%盐+0.1%BHT)、III. BPE(肉+2%盐+2%香蕉皮提取物)和 IV. SPE(肉+2%盐+2%人心果皮提取物),以研究在 8 天冷藏(4±℃)期间颜色和脂质氧化的变化。BPE 和 SPE 的平均酚含量分别为 550.2 和 550.8 mg 没食子酸当量/10 g 皮。BPE 和 SPE 的自由基清除活性分别为 66.9%和 67.8%。与人心果皮提取物(0.91)相比,香蕉皮提取物的还原活性(1.6)显著(P<0.05)更高。在冷藏期间,所有处理的颜色参数均显著下降。脂质氧化观察显示,与其他三种处理相比,对照的 TBARS 值显著升高(P<0.05)。从初始储存日到最后储存日,TBARS 的增加在对照中最高(514.3%),其次是 BHT(387.7%)、BPE(370.6%)和 SPE(383.7%)。两种合成抗氧化剂和天然提取物均显著降低了 TBARS 值。在 8 天的储存期间,TBARS 值的平均降低率分别为 BHT、BPE 和 SPE 处理的 56.8%、38.3%和 37.2%。因此,结论是从香蕉和人心果皮中提取的水提取物可以作为家禽肉和肉类产品中的天然抗氧化剂。
