Secret: plant "gold" extraction technology!
Just saw this title, I believe you will be surprised, how can there be "gold" in the plant? In fact, the "gold" mentioned by the editor here is not the kind of gold we often see, but the cannabinoids in plants, and its price is almost comparable to gold!
First of all, I would like to introduce industrial hemp to you. Industrial hemp refers to hemp with a tetrahydrocannabinol content of less than 0.3%. In China, industrial hemp is called hemp, which is an annual herb of the genus Cannabis in the family Cannabinaceae. Plants are divided into industrial hemp and drug marijuana, and the hemp widely used at home and abroad is industrial hemp. The powder made from the stalk core of industrial hemp, that is, the hemp stalk core ultrafine powder modified coating technology is applied to military uniforms, which can exert the high strength and high performance characteristics of the product.
The industrial hemp that has been approved to be grown legally is a variety with low toxic content, and the THC value is lower than 0.3%. These industrial hemp (THC<0.3%) are considered to have no drug use value, but they are still a treasure, and their applications include at least textiles, paper, food, medicine, hygiene, daily chemicals, leather, automobiles, construction, decoration, packaging, etc. field. Is a classic production material.
As industrial hemp has gradually become an outlet in the capital market, business giants are scrambling to enter the market, and the value of industrial hemp extracts—cannabinoids—is rapidly being tapped. There are many kinds of cannabinoids and complex molecular structures. Extraction technology has become a technical barrier in the industrial hemp industry, and it is also the core weight of corporate strength and competitiveness.
Cannabinoid refers to the active ingredient found in Cannabis cannabis, and its receptor system (endocannabinoid system) exists in both the nervous and immune systems of mammals. At present, there are more than 130 known cannabinoids, which are mainly divided into cannabidiol CBD, tetrahydrocannabinol THC, cannabinoid CBC, cannabinol CBN, cannabigerol CBG, etc.
Taking CBD and THC as an example, the physical and chemical properties of the two are very close, and the extraction process is very difficult; in the CBD oil products that people often use, only 5%-19% of the active ingredients can be absorbed. In order to better realize the product use, the extraction method of cannabinoids is very important.
01How to extract cannabinoids?
CO2 extraction is divided into supercritical, subcritical, and "medium critical" categories and does not involve the use of chemical solvents for the purpose of preserving CBD and other beneficial compounds.
Carbon Dioxide Extraction
Solvent Extraction Solvent extraction
usually uses ethanol and butane as solvents to extract from cannabis plant excipients. The combination of the two works well, is simple and easy to operate, and can be operated at home. In the case of ensuring the extraction rate and purity, the method uses solvent extraction throughout the process, avoiding the use and residue of toxic organic solvents such as petroleum ether, and ensuring product safety.
Olive Oil Extraction
Heat the plant at a specific temperature for a period of time to activate the plant's chemicals, add olive oil, and heat for a period of time to finally obtain the cannabinoids.
Olive Oil Extraction
Dry Ice Extraction
The marijuana plant is cut into chunks and placed in a bucket, covered with ice, inverted, and the mixture is filtered through a mesh bag several times to finally dry the extract until it becomes a powder. This method takes time and effort, but it can also be done at home.
In addition to the dry ice extraction method
, there are many methods of obtaining cannabinoids such as cultivating genetically modified cannabis, biosynthesis and chemical synthesis. The above four methods are routinely used extraction methods.
The goal of cannabinoid extraction technology is to improve the extraction rate and purity of cannabinoids, remove THC residues as much as possible, avoid the use of toxic organic solvents as much as possible, ensure product safety and environmental protection, and reduce costs as much as possible. Among the current methods of obtaining cannabinoids, skilled extraction methods still occupy the mainstream position, and biosynthesis and chemical synthesis are the main directions for obtaining cannabinoids in the future.
02Are there any good or bad extraction techniques?
The extraction of cannabinoids goes through three steps: rough processing, fine processing and purification.
Rough processing refers to the extraction of all cannabinoids (including THC) from industrial hemp, commonly known as "crude extract", which cannot be used directly; filter the crude extract to filter out THC and other cannabinoids, and obtain precise cannabinoids according to demand , Refined cannabinoid products can basically meet the market demand; if you want to obtain a single product of cannabinoids with higher purity, you can perform purification operations, through the process of crystallization-purification-recrystallization-repurification, and finally obtain extremely high-purity cannabinoids single product.
The ancients said: If a worker wants to do a good job, he must first sharpen his tools. The rapid development of an industry is inseparable from the support of technology, especially efficient, green and sustainable technology. For example, in the industrial hemp extraction industry, excellent extraction technology is required. Innovative Tongheng's HPLC technology provides a good solution for the rapid extraction of industrial hemp.
