Problems solved by technology

As we all know, after the plant body is dried, its cell activity will undergo "irreversible" changes, the nutritional value will be greatly lost, and some nutrients will even be completely lost.
Also have after adopting cryopreservation, fresh stem of noble dendrobium color turns yellow, and after thawing, plant body becomes soft, exists and former fresh stem of noble dendrobium color and shape difference, the shortcoming that taste is poor and cost is higher

Embodiment 1

[0026] Sorting the fresh Dendrobium candidum, removing rotten Dendrobium candidum and impurities to obtain clean Dendrobium candidum. Soak the clean Dendrobium officinale in 4 times the weight of 35°C fresh-keeping solution for 30 minutes, then use a centrifuge to remove the water on the surface of Dendrobium officinale, and place it for 3 hours under the condition of a vacuum of -0.06MPa and a temperature of 0°C , and then carry out vacuum packaging under the vacuum condition of -0.06MPa to obtain the dendrobium finished product. Wherein, the fresh-keeping solution is made up of sodium percarbonate, chlorine dioxide and water, and the weight percent content of sodium percarbonate in the fresh-keeping solution is 1%, and the content of chlorine dioxide in the fresh-keeping solution is 80mg / L. Dendrobium finished products are stored at 0°C to ensure quality when they are not edible.

Embodiment 2

[0028] The fresh Dendrobium candidum stored at 4°C is taken out, sorted, and rotten Dendrobium candidum and impurities are removed to obtain clean Dendrobium candidum. Soak the clean Dendrobium officinale in 3 times the weight of 40°C fresh-keeping solution for 20 minutes, then use a centrifuge to remove the moisture on the surface of Dendrobium officinale, and place it under the condition of a vacuum of -0.05MPa and a temperature of 2°C for 2 hours , and then carry out vacuum packaging under the vacuum condition of -0.07MPa to obtain the dendrobium finished product. Wherein, the fresh-keeping solution is made up of sodium percarbonate, chlorine dioxide and water, and the weight percent content of sodium percarbonate in the fresh-keeping solution is 0.8%, and the content of chlorine dioxide in the fresh-keeping solution is 60mg / L. Dendrobium finished products are stored at 2°C in order to ensure quality when not edible.

Embodiment 3

[0030] The fresh Dendrobium officinale preserved at 2°C was taken out, sorted, and rotten Dendrobium officinale and impurities were removed to obtain clean Dendrobium officinalis. Soak the clean Dendrobium chrysalis in 3 times the weight of 40°C fresh-keeping solution for 20 minutes, then use a centrifuge to remove the water on the surface of Dendrobium chrysalis, and place it under the conditions of a vacuum of -0.05MPa and a temperature of 2°C 2 hours, then carry out vacuum packing under the vacuum condition of-0.07MPa, get the dendrobium finished product. Wherein, the fresh-keeping solution is made up of sodium percarbonate, chlorine dioxide and water, and the weight percent content of sodium percarbonate in the fresh-keeping solution is 1.5%, and the content of chlorine dioxide in the fresh-keeping solution is 70mg / L. Dendrobium finished products are stored at 4°C to ensure quality when not edible.

Abstract

The invention relates to a method for fresh-keeping of dendrobe, belonging to the technical field of fresh-keeping. The method takes fresh dendrobe as a raw material, and sequentially comprises the steps of preprocessing, soaking in a fresh-keeping solution, centrifugal dewatering, low-temperature vacuum processing and packaging to obtain the finished dendrobe product. The method has the beneficial effects of being capable of keeping the special characteristics and the nutrient content of dendrobe for a long time, and solving the problem that fresh dendrobe cannot be supplied in a balanced mode.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping, and in particular relates to a fresh-keeping method of Dendrobium nodrobii. Background technique [0002] Dendrobium is a perennial herb of the genus Dendrobium in the family Orchidaceae, belonging to the epiphytic orchid class. Before 1980, only 57 species of Dendrobium were found in my country. Later, 19 species of Dendrobium were discovered and named after investigation, which enriched the germplasm resources of Dendrobium in my country. Now there are 76 species, accounting for about 5% of the world's Dendrobium species. Dendrobium is an important commonly used traditional Chinese medicinal material. Historically, its medicinal development and utilization are at the forefront of the world. [0003] The 2000 edition of the "Pharmacopoeia of the People's Republic of China" contains 5 species of medicinal Dendrobium, namely Dendrobium ring grass, Dendrobium verbena, Dendrobium yellow grass...
