摘要
为探究二氧化硅纳米颗粒(SiNPs)处理对生姜(Zingiber officinale Roscoe.)采后贮藏品质的影响,以凤头姜仔姜为材料,用100 mg/L SiNPs(SiNP100)溶液进行浸泡处理,分析仔姜在(12±1)℃、相对湿度为85%~90%的贮藏条件下的品质和生理变化.结果表明,SiNP100处理可有效延缓采后仔姜贮藏品质的变化.贮藏28 d时,SiNP100处理的仔姜硬度、失重率、可溶性固形物、可溶性蛋白含量相较于对照分别提高了7.76%,57.81%,26.76%和19.74%;过氧化物酶、过氧化氢酶、超氧化物歧化酶活性相较于对照分别提高149.18%,90.01%和10.27%;苯丙氨酸解氨酶、多酚氧化酶活性与对照相比分别下降8%,62.28%;类黄酮含量比对照提高26.24%.综上,SiNPs处理可有效维持采后仔姜的贮藏品质.
To investigate the effect of silicon dioxide nanoparticles(SiNPs) treatment on the postharvest storage and preservation quality of ginger,'Fengtou' gingers were used as the material and treated with 100 mg/L SiNPs(SiNP100) solution,to analyze the preservation quality and the changes of tender ginger under storage conditions of(12±1) ℃ and relative humidity of 85%~90%.The results showed that soaking in SiNP100 solution can effectively maintain the storage quality of postharvest tender ginger.After storage for 28 days,compared with the control,the hardness,weight loss rate,soluble solids,and soluble protein content of SiNP100-treated tender ginger was increased by 7.76%,57.81%,26.76%,and 19.74%,respectively,the activities of peroxidase,catalase,superoxide dismutase was increased by 149.18%,90.01% and 10.27%,respectively,the phenylalanine ammonia lyase and polyphenol oxidase activities was decreased by 8% and 62.28%,respectively.The flavonoid content was 26.24% higher than that of control.In summary,SiNPs treatment can effectively maintain the storage quality of postharvest tender ginger.
