Problems solved by technology

Zinc is one of the important trace elements necessary for human and animal survival. It is an important component of more than 100 enzymes in the human body. It also plays a role in regulating gene expression, regulating body immunity, cell reproduction and differentiation, body growth and metabolism. It plays a very important role, but because the human body is not easy to absorb inorganic zinc salts, the fourth-generation zinc supplement products currently on the market cannot be widely used due to the side effects of irritating the stomach, low digestion and absorption rate, or high cost and difficult to popularize. Very well meet the needs of the human body for zinc supplementation

[0016] A preparation method of Enteromorpha functional oligosaccharide zinc, its concrete steps are as follows:

[0017] 1) Extraction of Enteromorpha functional oligosaccharides: Take the Enteromorpha powder that has been dried, crushed, and passed through a 60-80 mesh sieve, and add an ethanol solution with a mass concentration of 30%-80% to infiltrate for 30 -60min, then ultrasonically extract twice at 30-60°C and 100-500W, each time for 30-90min, combine the extracts, filter with suction, and concentrate the filtrate to 5% of the original volume under reduced pressure;

[0018] 2) Deproteinization: Mix n-butanol and chloroform at a volume ratio of 1:4, add to the extract obtained in step 1), shake vigorously for 20 minutes and then centrifuge to remove the denatured protein at the junction of the water layer and the solution layer; repeat this step Operate until the denatured protein is completely removed;

[0019] 3) Removal of polysaccharides: Rotate the deproteinized e...

Abstract

The invention discloses enteromorpha functional oligosaccharide zinc and a preparation method thereof. The principle that an oligosaccharide compound can form a stable complex with metal salt is adopted, after the enteromorpha functional oligosaccharide is extracted by adopting the enteromorpha as raw materials, deproteinization and polysaccharide removal are carried out, and then the enteromorpha functional oligosaccharide is compounded with Zn<2+> to prepare novel organic zinc salt which has biological activity and is easily absorbed by a human body. The prepared enteromorpha functional oligosaccharide zinc integrates the healthcare functions of the functional oligosaccharide and trace element zinc and has the characteristics of non-toxicity, no pollution, good water solubility, good biological effectiveness and high conversion rate in a biological pH range; the equipment is simple, the cost is low, the operation is easy, a novel resource can be developed for supplementing zinc to the human body, and the economical additional value of the enteromorpha resource can be greatly increased by virtue of the high-value development and application.

Description

technical field [0001] The invention belongs to the fields of medicine and health products, and in particular relates to functional oligosaccharide zinc of Enteromorpha enteromorpha and a preparation method thereof. Background technique [0002] Enteromorpha belongs to the genus Enteromorpha of the Ulvaceae family of Chlorophyta, commonly known as "sea green vegetables" and "green laver". It is an important economic seaweed, mostly wild algae species, widely distributed in estuaries and stone marshes in the mid-tidal zone. my country's wild Enteromorpha resources are very rich, and are distributed in coastal areas such as Shandong, Jiangsu, Zhejiang, Fujian and other sea areas. "Compendium of Materia Medica" records that Enteromorpha "burns the powder and blows the nose to stop epistaxis, soaks in soup, smashes and applies swelling and pain on the back of the hand". Relevant studies have found that Enteromorpha contains a variety of essential nutrients for the human body. I...
