真空密封保鲜天麻研究

Study on vacuum sealed preservation of Gastrodia elata Blume

为探究天麻的保鲜方法,以贵州天麻为材料,设置不添加保鲜剂+蒸制、添加保鲜剂+蒸制及不添加保鲜剂+免蒸制(CK)3个处理,常温保存20、40、60、80 d后,分别取样测定天麻样品的外观形态及品质指标。结果表明,不添加保鲜剂+免蒸制处理的保鲜效果较差;不添加保鲜剂+蒸制处理能达到较好的保鲜效果且具有保证天麻原有气味、操作简单、成本较低等优点;添加保鲜剂且蒸制的保鲜效果最好,保鲜时间最长。

In order to explore the preservation method of Gastrodia elata Blume, taking G. elata in Guizhou as materials, 3 treatments including no preservative ＋steamed, preservative ＋steamed and no preservative ＋free steamed （CK） were set. After 20, 40, 60, 80 d preservation at room temperature, the appearance and quality index of G. elata samples were determined. The results showed that the effect of CK was poor; no preservative but steamed processing could achieve good preservation effect and ensure the original smell of G. elata, and the operation was simple, low cost; the effect of preservative＋steamed treatment was best, and the preservation time for G. elata was the longest.
