Benefits of technology

This new type of green plant called Clematis zosteris has been developed by researchers at home or abroad during their last two decades due to its unique benefits such as being able to maintain good quality vegetables over time with minimal effort needed compared to traditional methods like pickling them out after they have gone through certain stages of ripening processes. Additionally, this new technique does away with harmful pesticides used on cropped plants while still providing nutritional value. Overall, these technical improvements make it easier than ever before to produce high-quality food products worldwide.

Problems solved by technology

The technical problem addressed by this patented technology relates to how healthy deoxyribonucleces (DNA) are produced on demand without losing their strength or effectiveness due to environmental factors such as moisture content and pH levels that may damage them over time.

example 1

[0009] Example 1 Remove buds, leaves, impurities and thin and rigid branches from 10kg of Dendrobium candidum fresh strips, wash and drain with clear water, spread thinly in a bamboo sieve and let stand in a cool and dry place for 10 hours, put the fresh Dendrobium candidum strips in 4 batches. Put 10 kg of tea polyphenols and 4% tea polysaccharides into 10 kg of aqueous solution at room temperature, soak each batch for 30 seconds, take it out and put it in a bamboo sieve to dry, put it into a clean cardboard box according to the packaging specifications, and then leave the warehouse.

example 2

[0010] Example 2 Remove buds, leaves, impurities and thin and rigid branches from 100kg fresh strips of Dendrobium candidum, wash and drain with clear water, spread thinly on a cool, dry clean ground and let stand for 12 hours, put fresh strips of Dendrobium candidum in 10 batches 50 kg of water solution containing 2% tea polyphenols and 3% tea polysaccharides at room temperature, each batch soaked for 30 seconds, taken out and placed on a clean countertop to dry, put into a clean cardboard box according to the packaging specifications and then shipped out.

example 3

[0011] Example 3 Remove buds, leaves, impurities and thin and rigid branches from 1000kg Dendrobium candidum fresh strips, wash and drain with clear water, spread thinly on a cool, dry clean ground and let stand for 12 hours, put the fresh Dendrobium candidium strips in 50 batches 100 kg of water solution containing 3% tea polyphenols and 5% tea polysaccharides at room temperature, each batch soaked for 30 seconds, taken out and placed on a clean countertop to dry, put into a clean cardboard box according to the packaging specifications and then shipped out.

[0012] The technological process of the present invention is simple, easy to operate, and can be widely used in the dendrobium planting enterprises in southern my country, and all the antistaling agents used are natural products of food materials. The weight loss rate of the treated Dendrobium candidum strips is less than 3% within 15 days at room temperature, and the taste has no obvious change, which fully meets the req...

Abstract

The invention discloses a preservation method of fresh dendrobium nobile branches. The method comprises the main steps as follows: picked dendrobium nobile is cleaned after bud leaves are removed andsecondary stems are rejected; the cleaned fresh dendrobium nobile branches are spread at normal temperature for 12 h; the fresh dendrobium nobile branches are soaked in a normal-temperature aqueous solution containing 2%-3% of tea phlyphenol and 3%-5% of tea polysaccharide for 30 s in batches, then, the fresh dendrobium nobile branches are taken out and placed in a bamboo sieve to be aired, and the dried fresh dendrobium nobile branches are placed in clean cartons according to packaging specifications and delivered. The clean dendrobium nobile branches are left to stand in a shade place for about 12 h, so that cuts can quickly form callus by use of the emergency regulation function of fresh branches to prevent wounds from infection, the tea polyphenol is used for quick soaking to play sterilization and bacteriostasis roles, the tea polysaccharide is used for quick soaking to form polysaccharide film layers to effectively weaken respiration intensity and moisture diffusion of the freshdendrobium nobile branches, and the weight maintenance and preservation effects are realized.
