中文摘要: 为探究淮山的合理烹饪方式,提高淮山菜肴的品质,以新鲜淮山为对照,研究微波、清蒸、水煮、热炒4种烹饪方式对淮山感官品质、营养成分和功能活性的影响。结果表明,不同烹饪时间的淮山感官品质差异显著(P<0.05),水煮、清蒸、热炒和微波4种烹饪方式的最佳烹饪时间分别为11、12、9 min和6.5 min。经烹饪处理后,蛋白质、尿囊素、黄酮、多酚和多糖含量显著降低(P<0.05),淮山活性成分的损失程度由低至高依次为清蒸、水煮、微波和热炒。不同烹饪方式对淮山DPPH自由基和羟自由基清除能力的影响不同,其中清蒸烹饪处理样品的抗氧化活性最高。清蒸烹饪方式能降低淮山营养成分和活性成分的损失。
Abstract:The effect of boiling,steaming,stir-frying and microwaving on color,sensory quality,nutrients and functional ingredients of yam was investigated.The results showed that the cooking time had a significant effect on the sensory quality of yam(P<0.05).The optimal cooking time of boiling,steaming,stir-frying and microwaving were 11,12,9 min and 6.5 min,respectively.After cooking,the contents of protein,allantoin,flavonoids,polyphenols and polysaccharides were significantly decreased (P<0.05),the highest functional ingredients content was observed in steaming sample,followed by boiling,microwaving and stir-frying.Furthermore,the effects of different cooking methods on the scavenging ability of yam DPPH free radicals and hydroxyl free radicals were different,and the steaming sample had the highest antioxidant activity.
