Fresh ginseng was buried in three types of sand with different moisture contents and three types of soil and then stored at 2 °C to determine the effects of these storage substrates on fresh ginseng.
At a storage time of 200 days, ginseng stored in underforest soil softened the most slowly and had a significantly greater firmness compared to the other samples (P < 0.05). The amount of most ginsenosides changed after storage for most of the substrates. Samples stored in ginseng soil and biological fertilizer had the highest concentration of total saponin and ginseng polysaccharides, respectively. Fresh ginseng stored in medium-water content sand had a significantly lower polyphenol oxidase activity (P < 0.05). A significant difference was observed in the total concentration of nucleosides and nucleobases between the ginseng samples stored with and without substrates (P < 0.05).
The data obtained in the present study suggest that the use of storage substrates is an optimal method for extending the shelf life of fresh ginseng without detrimental effects on its components. © 2019 Society of Chemical Industry.
将鲜人参分别埋入三种不同含水量的沙土和三种土壤中，在 2℃下贮藏，以确定这些贮藏基质对鲜人参的影响。
在贮藏 200 天的时间内，林下土中贮藏的人参软化最慢，与其他样品相比硬度显著更大（P<0.05）。大多数基质贮藏后大部分人参皂苷的含量发生了变化。在人参土和生物肥料中贮藏的样品分别具有最高浓度的总皂苷和人参多糖。中含水量沙土中贮藏的鲜人参的多酚氧化酶活性显著较低（P<0.05）。有和没有基质贮藏的人参样品之间的核苷和碱基的总浓度存在显著差异（P<0.05）。
本研究的数据表明，使用贮藏基质是一种延长鲜人参保质期的最佳方法，且对其成分没有不利影响。 © 2019 化学工业协会。
