Problems solved by technology

[0003] Dendrobium is still a living body after picking. It not only contains alkaloids, vegetable proteins, glycoside volatile oils, but also starch, sugars, amino acids, organic acids, cellulose, and inorganic elements. Mildew, taste change, water loss, etc. occur during processing and storage, and the active ingredients are seriously lost, making it impossible to achieve long-term storage

Embodiment 1

[0040] The same batch of Dendrobium candidum with good appearance, no mechanical damage and mildew was selected for weighing, and the medicinal components such as polysaccharides and extracts were tested to facilitate comparative analysis with Dendrobium at the later stage of storage. Divide Dendrobium into two groups: one group is put into the 3 / (m 2 ·24h·0.1MPa) high-barrier membrane air-modified bag, and the humidity in the bag is controlled at 65%; the other group is put into an ordinary linen bag. Then fill the airtight bag with nitrogen and carbon dioxide, wait until the oxygen content in the bag drops to less than 3%, and the carbon dioxide content is filled to about 5%, and the bag is placed in an environment at 2°C for storage.

[0041] During storage, check the gas content in the bag at least every 1 to 2 weeks, and record the data. When the oxygen and carbon dioxide content exceeds the upper limit allowed by the test, re-breathe the gas in the bag. The controlled...

Embodiment 2

[0044] Select Dendrobium officinale of the same batch with good appearance, no mechanical damage and mildew, weigh them, and divide them into three groups: In the first group, put several Dendrobium directly into the 3 / (m 2 ·24h·0.1MPa) in the high-barrier membrane air-modified bag; the second group puts 5-8 stems of dendrobium into a plastic tray with air holes, and then puts it into the air-modified bag; The three groups put the dendrobium into the linen bag and controlled the humidity at about 65%. Then fill nitrogen and carbon dioxide into the modified atmosphere bag, and when the oxygen content in the bag drops to less than 3%, and the carbon dioxide concentration is 8%-10%, the bags are all placed in an environment of 2°C for storage.

[0045] During storage, check the gas content in the bag at least every 1 to 2 weeks, and record the data. When the oxygen content exceeds the upper limit allowed by the test, re-ventilate the gas in the bag. The controlled atmosphere s...

Embodiment 3

[0048] Select Dendrobium officinale of the same batch with good appearance and appearance, no mechanical damage and mildew to weigh, and divide the weighed Dendrobium officinale into three groups: one group puts a single dendrobium in a plastic tray, and puts the dendrobium into three groups. Put a single dendrobium in a modified atmosphere bag; put several dendrobiums in a plastic box for one group; put the last group of dendrobiums in a foam box, and control the humidity of the three groups at 65% RH. Gas replacement was performed on the three groups of bags so that the oxygen content in the bags was reduced to 3%, and the carbon dioxide was increased to 8%-10%, and then all were stored in an environment at 2°C.

[0049] During storage, check the gas content in the bag at least every 1 to 2 weeks, and record the data. When the oxygen content and carbon dioxide content exceed the limit allowed by the test, re-ventilate the gas in the bag. The controlled atmosphere storage cyc...

Abstract

The invention relates to a modified atmosphere fresh-keeping method of dendrobium. The modified atmosphere fresh-keeping method comprises the following steps: putting dendrobium into a modified atmosphere package; keeping the relative humidity in modified atmosphere packaging within 60%-80% RH; reducing the oxygen content in the modified atmosphere packaging to a first threshold range; and storingthe modified atmosphere packaging at a low temperature, wherein the storage time is at least half a month. The modified atmosphere fresh-keeping method for dendrobium nobile is convenient to operate,reduces resource waste, effectively reduces mildewing, water loss, color change, taste change, mechanical injury and loss of effective components of dendrobium nobile in production places, transportation and storage environments, and prolongs the fresh-keeping period of dendrobium nobile.

Description

technical field [0001] The invention relates to the field of modified atmosphere conservation, in particular to a modified atmosphere fresh-keeping method for dendrobium. Background technique [0002] Dendrobium is a perennial epiphytic herb of the Orchidaceae Dendrobium genus. It has the effects of nourishing the stomach and promoting body fluid, nourishing yin and clearing heat, moistening the lungs and relieving cough. At the same time, Dendrobium candidum also has the functions of enhancing human immunity and anti-tumor. Because of its unique medicinal and health value, it has been excavated by predators for a long time, resulting in the serious depletion of wild resources. Dendrobium mostly grows in high-temperature and humid areas. Its own reproductive capacity is low, growth is slow, and affected by the environment, it is prone to root rot and even the death of the whole plant. [0003] Dendrobium is still a living body after picking. It not only contains alkaloids, ...
