摘　　要：目的:延长鲜切兰州百合贮藏期。方法:以兰州百合为原材料,经鲜切加工处理后,采用0(CK),1,5,10 g/L的异抗坏血酸钠(SI)溶液进行浸泡处理,分析贮藏过程中鲜切兰州百合的品质变化。结果:10 g/L的SI浸泡处理可以更好地维持鲜切兰州百合鳞片的亮度,贮藏21 d时,褐变度、可溶性糖和丙二醛含量分别比CK组低23%,8%,45%。在贮藏结束时,SI处理组的多酚氧化酶、过氧化物酶和脂氧合酶活性分别为97.22,0.09,11.89 U/g,显著低于CK组(P<0.05)。电子鼻分析表明,SI处理对贮藏期间鲜切兰州百合的风味有调节作用。结论:SI浸泡处理是一种操作简便,经济安全的采后处理技术,可以延缓鲜切兰州百合氧化褐变,从而维持其贮藏品质。Objective:This study aimed to extend the storage period of fresh-cut Lanzhou lily.Methods:Fresh-cut Lanzhou lily was used as raw materials.Following fresh-cut processing,the raw materials were soaked with 0(CK),1,5,and 10 g/L of SI solution to analyze the quality changes of fresh-cut Lanzhou lily during storage.Results:The soaking treatment with 10 g/L of SI could better maintain the brightness of freshly cut Lanzhou lily.At 21 days of storage,the concentrations of malondialdehyde,soluble sugar,and browning were,respectively,45%,8%,and 23%lower than those of the CK group.The SI-treated group had significantly decreased polyphenol oxidase,peroxidase,and lipoxygenase(97.22,0.09,and 11.89 U/g,respectively)activity at the end of storage compared to the CK group(P<0.05).In addition,electronic nose analysis showed that SI treatment modulated the flavor of fresh-cut Lanzhou lily during storage.Conclusion:SI soaking treatment is a simple,economical,and safe post-harvest treatment technique that can delay the oxidative browning of fresh-cut Lanzhou lily and thus maintain its quality during storage.
