Embodiment 1

[0025] A fresh-keeping method of dendrobium candidum, the following steps are carried out successively:

[0026] 1) Pretreatment of the harvested wound: after harvesting the fresh strips of Dendrobium candidum, remove the leaves of the picked Dendrobium candidum and cut at 3mm above the wound with a knife, and ensure that the cut is neat;

[0027] 2) Cooling treatment: use 25°C water during the cooling treatment, put the pretreated fresh strips of Dendrobium candidum into a cold water basin and soak for 7 minutes;

[0028] 3) Incision cleaning: During soaking in cold water to cool down, use a towel to gently rub the incision of the fresh Dendrobium candidum strips (other parts of the fresh Dendrobium candidum strips are not treated), and then change the soaking cold water twice;

[0029] 4) Surface drying treatment: Spread the fresh strips of Dendrobium candidum after the cooling treatment on a stainless steel grid, lay a water-absorbing towel on the grid, press the surface of...

Embodiment 2

[0033] A fresh-keeping method of dendrobium candidum, the following steps are carried out successively:

[0034] 1) Pretreatment of harvested wounds: after harvesting the fresh strips of Dendrobium candidum, remove the leaves of the picked Dendrobium candidum and cut them at 4 mm above the wound with a knife, and ensure that the cuts are neat;

[0035] 2) Cooling treatment: use 16°C water during the cooling treatment, and put the pretreated fresh strips of Dendrobium candidum into a cold water basin to soak for 5 minutes;

[0036] 3) Incision cleaning: During soaking in cold water to cool down, use a towel to gently rub the incision of the fresh Dendrobium candidum strips (other parts of the fresh Dendrobium candidum strips are not treated), and then change the soaking cold water twice;

[0037] 4) Surface drying treatment: Spread the fresh strips of Dendrobium candidum after cooling treatment on a stainless steel grid, lay disposable absorbent paper on the grid, and gently pr...

Embodiment 3

[0041] A fresh-keeping method of dendrobium candidum, the following steps are carried out successively:

[0042] 1) Pretreatment of harvested wounds: after harvesting the fresh strips of Dendrobium candidum, remove the leaves of the picked Dendrobium candidum and cut them at 5 mm above the wound with a knife, and ensure that the cuts are neat;

[0043] 2) Cooling treatment: use 20°C water during the cooling treatment, and put the pretreated fresh strips of Dendrobium candidum into a cold water basin to soak for 7 minutes;

[0044] 3) Incision cleaning: During soaking in cold water to cool down, use a towel to gently rub the incision of the fresh Dendrobium candidum strips (other parts of the fresh Dendrobium candidum strips are not treated), and then change the soaking cold water twice;

[0045] 4) Surface drying treatment: Spread the fresh strips of Dendrobium candidum after the cooling treatment on a stainless steel grid, lay a water-absorbing towel on the grid, press the su...

Abstract

The invention discloses a preservation method of dendrobium. The method comprises the following steps of carrying out pretreatment on a harvest wound of the dendrobium, and then subjecting the dendrobium to cooling treatment, incision washing, drying treatment, hermetic packaging and refrigeration treatment in sequence. By adopting the preservation method, the preservation period of the dendrobium is as long as 93 days to 110 days; the water loss rate is between 5 percent and 10 percent; the trait of the dendrobium cannot be changed; a nutrient substance that the dendrobium contains cannot be also degraded; an operation method of the preservation method is simple; used materials are environmentally friendly and moreover materials are taken widely; the popularization range is not limited by a device and a facility.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping, in particular to a fresh-keeping method of Dendrobium nodrobii. Background technique [0002] The fresh strips of Dendrobium candidum that have just been picked are still a living body. With the progress of respiration and transpiration, their quality will gradually change during the storage process. The main manifestations are: weight loss, loss of nutrients, sensory deterioration, Microbial pollution leads to wine or sour taste, and eventually rots and disintegrates to lose commodity value, and has a certain impact on the color, texture, smell and taste of the product. At present, the fresh-keeping technology of Dendrobium officinale commonly used in China and its disadvantages mainly include: [0003] Low temperature storage: low temperature will cause chilling injury, easy to infect bacteria, and need to improve the cold chain; [0004] Controlled atmosphere storage: It will produce e...
