Embodiment 1

[0028] A method of utilizing low temperature stress to improve polysaccharides of Dendrobium officinale, such as figure 1 As shown, the method carries out low temperature stress treatment to the fresh strips of Dendrobium candidum after harvesting, to improve the polysaccharide content of the fresh strips of Dendrobium candidum, and improves the ratio of mannose to glucose; the fresh strips of Dendrobium candidum after low temperature stress treatment Among them, the type and content of polysaccharides are higher than 37%, and the ratio of mannose to glucose is higher than 4:1.

[0029] The low temperature stress treatment comprises the following steps:

[0030] (1) Drying step: air-dry the harvested fresh Dendrobium candidum strips at 35° C. until there is no water trace on the surface of the fresh Dendrobium candidum strips.

[0031] (2) Low temperature treatment step: the treatment temperature is 4° C., and the low temperature treatment time is 2 days.

[0032] (3) Restor...

Embodiment 2

[0035] A method of utilizing low temperature stress to improve polysaccharides of Dendrobium officinale, said method carries out low temperature stress treatment to fresh strips of Dendrobium officinale after harvesting, and the specific methods are as follows:

Abstract

The invention mainly belongs to the technical field of dendrobium officinale processing, and in particular relates to a method for improving dendrobium officinale polyose by using a low-temperature stress effect. According to the method, low-temperature stress treatment is carried out on the harvested fresh dendrobium officinale strips to improve the polyose content of the fresh dendrobium officinale strips and improve the composition proportion of monosaccharose; and the low-temperature stress treatment comprises the following steps: airing, low-temperature treatment and restoration treatment of metabolism. The method provided by the invention can improve the polyose content in the fresh dendrobium officinale strips, and improve the composition proportions of mannose and glucose in the fresh dendrobium officinale strips, so the quality of the prepared fresh dendrobium officinale strips is better.

Description

technical field [0001] The invention mainly belongs to the technical field of dendrobium candidum processing, and specifically relates to a method for improving polysaccharides of dendrobium candidum by using low temperature stress. Background technique [0002] Dendrobium officinale Kimura et Migo (Dendrobium officinale Kimura et Migo) is a perennial epiphytic herb belonging to Dendrobium officinale and is one of the most precious Chinese herbal medicines in my country. Efficacy and a wide range of applications are gradually known. With the integration of planting technology, the planting industry of Dendrobium officinale has achieved large-scale and intensive development, and the planting area and output have increased year by year. In April 2016, China's Health and Family Planning Commission officially issued a request for opinions on listing Dendrobium officinale as a new food raw material. This provides a good opportunity for the further market promotion of Dendrobium ...
