Problems solved by technology

Based on this discovery, the inventors creatively proposed to use sand and Chinese fir chips in combination, that is, put the rhizomes of Polygonum vermicelli on the sand, and lay Chinese fir chips on the upper surface of the rhizomes of Polygonum vermicelli, which can overcome the damage caused by the embedding of Polygonum vermicelli. The problem that the upper surface of the rhizome becomes dry can also overcome the problem that the lower layer of Polygonum viburnum rhizome is prone to mildew caused by the embedding of fir sawdust

Embodiment 1

[0030] Embodiment 1 finds the problem

[0031] The rhizome of Polygonum villosa newly excavated from Nyingchi, Tibet, without mold and brown stain, was selected as the experimental object. Chinese fir sawdust was purchased from Lingshou County Huiheng Mineral Products Processing Plant, pH5.0-5.5.

[0032] 1.1 Method

[0033](1) spread dry sand (moisture content 2.5%, particle diameter 0.3-0.5mm) or water content to be 70% Chinese fir chips on the bottom layer, then weigh about 200 grams / box of Polygonum viburnum rhizomes and put them into wooden boxes, Cover dry sand (water content 2.5%, particle diameter 0.3-0.5mm) or the Chinese fir chips that water content is 70% respectively at last; The control group is directly placed in the wooden box;

[0034] (2) Experimental group:

[0035] Treatment group:

[0036] a. Chinese fir chips: 75 grams of the bottom layer (about 2 cm in thickness), about 200 grams of rhizomes, and 125 grams of the upper layer (about 4 cm in thickness);...

Embodiment 2

[0054] The rhizome of Polygonum villosa newly excavated from Nyingchi, Tibet was selected as the experimental object.

[0055] 2.1 Method:

[0056] (1) Lay one deck dry sand (water content 2.5%, particle diameter 0.3-0.5mm) or water content be 65% Chinese fir chips on the bottom layer, then weigh about 500 grams / box of Polygonum viburnum rhizomes and put them into wooden boxes, Cover dry sand (water content 2.5%, particle diameter 0.3-0.5mm) or water content respectively at last and be the Chinese fir chips of 65%; The control group is directly placed in the wooden box;

[0057] (2) Experimental group

[0058] Treatment group:

[0059] a. Chinese fir sawdust: spread a layer of Chinese fir sawdust with a thickness of about 2cm on the bottom layer, put about 500 grams of rhizomes, and cover the upper layer with a thickness of about 3cm Chinese fir sawdust;

[0060] b. Dry sand: spread a layer of sand with a thickness of about 2cm on the bottom layer, put about 500 grams of rh...

Embodiment 3

[0079] The rhizome of Polygonum villosa newly excavated from Nyingchi, Tibet was selected as the experimental object.

[0080] 3.1 Method:

[0081] (1) The Polygonum viburnum rhizomes that take about 4kg are put into 1.5g / L 97% trichloroisocyanuric acid solution (weighing 1.5g purity is that 97% trichloroisocyanuric acid is dissolved in 1L water to obtain), soak for about 15 minutes, drain the water, and air-dry naturally until there are no water drops on the surface of Polygonum viburnum;

[0082] (2) Lay a layer of dry sand (water content 2.5%, particle size 0.3-0.5mm) or Chinese fir chips with a water content of 68% at the bottom of the box, and put the rhizome of Polygonum viburnum soaked in 97% trichloroisocyanuric acid Put it into a wooden box and cover it with dry sand (water content 2.5%, particle size 0.3-0.5mm) or Chinese fir chips with a water content of 68%, see the following treatment groups for details; ) Soaked Polygonum victoriae rhizomes are directly placed ...

Abstract

The invention provides a method for preserving the freshness of Polygonum viburnum. The method comprises: setting the Polygonum vermicelli fresh medicine above a lower fresh-keeping layer, the lower fresh-keeping layer being made of dry sand; and setting an upper fresh-keeping layer above the Polygonum vermicelli fresh medicine, and the upper fresh-keeping layer being made of sawdust. This method proposes for the first time the combination of sand and fir sawdust for long-term storage of the fresh medicine of Polygonum viburnum. The content of total sugar, crude protein, starch, fat and amino acid (hydrolyzed and free) in Polygonum decreased slowly, which reduced the color browning of fresh medicine, significantly improved the quality of Polygonum viburnum during storage, and prolonged the preservation time of fresh medicine in Polygonum viburnum.

Description

technical field [0001] The invention relates to the field of medicine, in particular, the invention relates to a fresh-keeping method of Polygonum villosa herb. Background technique [0002] Polygonum viviparum L. is a perennial herbaceous plant of the Polygonaceae genus, which mainly grows in hillside forests, alpine or subalpine meadows. The rhizome is used as medicine, commonly known as "Plateau Fist Ginseng", which is bitter and cool in nature and taste, and has the functions of reducing fever, stopping diarrhea, regulating menstruation, astringent, and hemostasis. Modern chemical research shows that Polygonum viburnum contains various components such as volatile oil, phenols (organic acids and flavonoids), sterols, polysaccharides, etc. Among them, phenols are important active components, which have antioxidant and antibacterial activities. [0003] Fresh medicine, that is, fresh traditional Chinese medicinal materials, generally refers to taking from nature and still ...
