Embodiment 1

[0031] The fresh-keeping method of Dendrobium officinale comprises the following steps:

[0032] (1) 2kg of freshly picked Dendrobium candidum is cleaned with 3°C water, and then the cleaned Dendrobium candidum is cooled to 1°C;

[0033] (2) placing the cooled Dendrobium officinale in a weight of 5 kg, and a temperature of 2° C. in a preservative for soaking for 3 minutes;

[0034] (3) place the dendrobium candidum after soaking for 45 minutes to drain;

[0035] (4) The dried Dendrobium candidum was sealed and packaged with a sterile fresh-keeping bag with a thickness of 0.03 mm on one side of PVC, 30 g per package, and then placed in a cold storage at 1° C. for storage.

[0036] The preservative in the step (2) is composed of the following raw materials in parts by weight: 25 parts of water, 75 parts of ethanol, 0.002 part of 1-methylcyclopropene, 0.002 part of γ-aminobutyric acid, 0.8 part of quercetin, 0.8 parts of proanthocyanidins, 0.8 parts of soybean isoflavones. Add...

Embodiment 2

[0038] Substantially the same as Example 1, the difference is only that the antistaling agent in the step (2) is made up of the following raw materials in parts by weight: 25 parts of water, 75 parts of ethanol, 0.004 part of 1-methylcyclopropene, quercetin 0.8 parts, procyanidins 0.8 parts, soybean isoflavones 0.8 parts. Add ethanol, 1-methylcyclopropene, quercetin, proanthocyanidins and soybean isoflavones into water, stir and mix evenly to obtain the preservative.

Embodiment 3

[0040] Basically the same as Example 1, the only difference is that the preservative in the step (2) is made up of the following raw materials in parts by weight: 25 parts of water, 75 parts of ethanol, 0.004 part of gamma-aminobutyric acid, 0.8 part of quercetin parts, 0.8 parts of proanthocyanidins, and 0.8 parts of soybean isoflavones. Add ethanol, γ-aminobutyric acid, quercetin, proanthocyanidins and soybean isoflavones into water, stir and mix evenly to obtain the preservative.

Abstract

The invention discloses a preservation method of dendrobium officinale. The method comprises the following steps: (1), washing picked fresh dendrobium officinale with water at 1 to 4 DEG C, and then cooling the dendrobium officinale to be 0 to 2 DEG C; (2), laying the cooled dendrobium officinale into a preservative at 1 to 4 DEG C, so as to perform soaking treatment on the dendrobium officinale; (3), draining off the soaked dendrobium officinale at 30 to 60 DEG C; (4), performing sealed package on the drained dendrobium officinale, and then storing the dendrobium officinale at 0 to 20 DEG C. The method can effectively keep the original components, color and brittleness, ensures low weight loss ratio, and guarantees the commodity value of dendrobium officinale; the preservation effect is good, the preservation time is long, the method is simple to operate, and the cost is low.
