Embodiment 1

[0037] Embodiment 1, a kind of fresh-keeping method of Dendrobium candidum, carries out following steps successively:

[0038] 1) Rapid cooling of 1 kg of harvested Dendrobium candidum to 0-2°C (completed within 30-60 minutes) to obtain cooled Dendrobium candidum;

[0039] 2) Clean the cooled Dendrobium officinale at a low temperature of 1-4°C, as follows:

[0040] First wash with 2L of clear water, then rinse with 2L of sodium bicarbonate solution with a mass concentration of 2%; get Dendrobium candidum after cleaning;

[0041] 3) Soak the cleaned Dendrobium candidum in a 2% sodium bicarbonate solution (about 5L) for 1 minute at a low temperature of 1-4°C; Immersed in sodium bicarbonate solution;

[0042] 4) Put the soaked Dendrobium candidum into a 5L airtight container at a low temperature of 1-4°C, and set a filter paper with 10ml of preservative on the bottom of the container. After cleaning, Dendrobium candidum and the filter paper will not direct contact.

Abstract

The invention relates to the technical field of post-harvesting preservation of a plant material, and particularly discloses a preservation method of dendrobium officinale. The preservation method of the dendrobium officinale comprises the following steps of (1) rapidly cooling the harvested dendrobium officinale to 0-2 DEG C; (2) cleaning the cooled dendrobium officinale at low temperature of 1-4 DEG C; (3) carrying out fumigation treatment on the cleaned dendrobium officinale for 12-24 hours at low temperature of 1-4 DEG C to obtain the processed dendrobium officinale, wherein the preservative is prepared from 1-methylcyclopropene, jasmonic acid methyl ester and water, wherein each 1L of preservative contains 50nL to 500muL of 1-methylcyclopropen and 0.1-10mM of jasmonic acid methyl ester; and (4) placing the processed dendrobium officinale in air for 30-60 minutes at room temperature, then tightly packaging, and storing at low temperature of 0-2 DEG C. By adopting the method, the quality guarantee period of fresh dendrobium officinale can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of post-harvest preservation of plant materials, in particular to a preservation technique for fresh edible Dendrobium officinale. Background technique [0002] Dendrobium officinale Kimura et Migo is a precious Chinese herbal medicine, containing multiple active ingredients such as Dendrobium officinale Kimura et Migo. Modern pharmacological research shows that it also has the functions of improving the body's immunity, anti-tumor and preventing cataracts, and is listed as one of the nine Chinese immortal grasses. Dendrobium candidum in China is mainly distributed in Zhejiang, Guangxi, Hunan, Yunnan, Guizhou and other places. [0003] Traditionally, for the convenience of transportation and storage, fresh products of Dendrobium candidum are often made into dry products (such as Tiepi Fengdou, Dendrobium powder capsules, granules, etc.) or other dosage forms. However, when Chinese medicine uses Dendrobium ...
