A method for extracting Artemisia polysaccharide from Artemisia annua seeds

Abstract

The invention discloses a method for extracting sa-son seed gum from artemisia sphaerocephala krasch seed. According to the method, artemisia sphaerocephala krasch seed is adopted as a raw material, a mechanized separation method is used, and selection, stirring and glue immersing, centrifugal separation, alcohol precipitation, filtering and separating, and drying crushing are performed to obtain the sa-son seed gum powder. Compared to the traditional extraction method, the method of the present invention has the simple production process, can achieve the mechanized batch pipeline operation, has characteristics of low cost, high extraction rate and high finished product purity, only uses the edible-grade alcohol in the alcohol precipitation, and does not use other chemical reagents, wherein the alcohol can be recovered and reused. The method of the present invention creates the feasible technical conditions for the large-scale processing and development of the sa-son seed gum health food.

Description

technical field [0001] The invention relates to a method for extracting Artemisia polysaccharides, in particular to a method for mechanically extracting Artemisia polysaccharides from Artemisia artemisiae seeds. Background technique [0002] The Artemisia annua seeds mentioned here are the seeds of Artemisia alba. Baisha punt is a perennial wild super-xerophytic psammophyte of the genus Artemisia in the family Asteraceae. It is a unique sand-fixing plant that is resistant to wind and sand, drought, cold, and barrenness in the arid areas of deserts in Northwest my country and North China. Artemisia annua seeds are edible and medicinal. Farmers and herdsmen in Northwest my country have had the habit of eating Artemisia annua seeds since ancient times. One is as a gluten enhancer for miscellaneous grains and cereal flour; the other is as an important oil plant. edible oil; the third is medicinal, according to "Chinese Materia Medica", Artemisia annua seeds can reduce inflammati...

Problems solved by technology

[0007] To sum up, the production equipment of dry glue production is simple, the process is short, the operation is easy, it is easy to mechanize batch operation, and the cost is low. It can be eaten directly and has no toxic side effects. The biggest disadvantage is that the yield is not high, the purity is very low, the appearance is poor, it is easy to mold and brown, and the quality of the product is poor. It is not suitable for making food or health care products.

The advantage of wet extraction of artemisia gum is that the purity is high, but the disadvantage is that the glue and seeds are separated by centrifugal filtration separation or vacuum filtration separation. Since the pore size of the filter is larger than the diameter of the seeds, the separation is very difficult, and the colloid contains a large amount of The grain needs to be filtered many times, and the slag contains a lot of colloid, which needs to be washed and filtered many times, and the yield of finished glue is low; the water consumption is large, and the direct heating and drying of the glue consumes a lot of energy, and the alcohol consumption of alcohol precipitation It is very large and the cost is extremely high; the process is complicated, and it is basically impossible to realize mechanized continuous operation, which is not conducive to stable mass production

Using organic swelling and chemical method to extract artemisia gum, the advantage is that the purity and quality of the product are significantly improved, and the disadvantage is that chemical substances such as strong acid, alkali and oxide hydrogen peroxide are used, which is not conducive to making food or health products; due to the modification reaction, The natural properties and physical and chemical properties of artemisia gum have changed; due to the use of a large amount of organic solvents ethanol and acetone, and a large amount of metal ions, acid radical ions and oxides in the crude product, the product cannot be used directly and must be washed , these undoubtedly increase the cost

In addition, the process is complicated and the operation is unstable, and it is also impossible to realize mechanized operations, which is not conducive to stable mass production

Artemisia polysaccharides have the obvious effects of maintaining intestinal health, controlling body weight, controlling blood sugar, and lowering blood lipids. The use of Artemisia polysaccharides to develop functional foods or health foods that clean up the intestinal tract, reduce fat, lower blood sugar, and prevent cardiovascular diseases It is very broad, but so far, the existing dry, wet and chemical extraction technologies are still in the small test stage, and there is no mature green industrialized batch extraction technology for Artemisia annua seed polysaccharides, and industrialized large-scale extraction can be carried out There is still a long way to go in the technical research of artemisia muscaria gum polysaccharide
