Embodiment 1

[0036] A preparation method of licorice polysaccharide iron chelate, said method comprises the following extraction of licorice polysaccharide and chelation of licorice polysaccharide and iron ions.

[0037] The extraction of the licorice polysaccharide comprises the following steps:

[0038] Step A1. Ultrasonic extraction of licorice polysaccharides: take annual licorice tablets with a moisture content of less than 6%, crush them, and pass through a 100-mesh sieve to obtain licorice powder. Accurately weigh 10 parts of licorice powder, add 200 parts of deionized water, and dissolve at 30 Sonicate for 40 min at ℃, then filter, collect the filtrate for later use, and transfer the filter residue to the reactor.

[0039] Step A2. Hot water extraction of licorice polysaccharide: add 200 ℃ of deionized water to the filter residue in step A1, reflux in a boiling water bath for 1 hour, then filter, collect the filtrate, combine the filtrate with the filtrate obtained in step A1, and ...

Abstract

The invention discloses a preparation method of a glycyrrhiza polysaccharide-iron chelate. The method comprises extraction of glycyrrhiza polysaccharide and chelation of glycyrrhiza polysaccharide andiron ions. The extraction of glycyrrhiza polysaccharide comprises ultrasonic extraction of glycyrrhiza polysaccharide, hot water extraction of glycyrrhiza polysaccharide and alcohol precipitation. The chelation of glycyrrhiza polysaccharide and iron ions comprises a chelation step and a separation and purification step. According to the preparation method of a glycyrrhiza polysaccharide-iron chelate, the obtained glycyrrhiza polysaccharide-iron chelate is high in iron content and stable in structure, free iron ions do not exist in an aqueous solution of the glycyrrhiza polysaccharide-iron chelate, irritation to intestines and stomachs is small, in addition, the glycyrrhiza polysaccharide-iron chelate further has the special smell of glycyrrhiza, the effects of immunity improving and physique strengthening can be achieved while iron is supplemented, and the glycyrrhiza polysaccharide-iron chelate can serve as a high-quality material of iron supplementing products.

Description

technical field [0001] The invention relates to the technical field of chelated iron, in particular to a preparation method of polysaccharide chelated iron. Background technique [0002] Iron is one of the essential trace elements needed for human survival. If the human body does not absorb enough iron, it is easy to cause iron deficiency anemia. At present, people can increase the iron content in the body by eating iron-containing foods or supplementing mineral iron. However, eating a large amount of iron-containing substances does not mean that iron is absorbed. In the process of digesting and absorbing iron, the human body usually needs to pass through Amino acids or other organic substances form chelates with iron and can only be absorbed when they are in a state that can be absorbed. A large number of studies have shown that the human body absorbs much more "chelated" iron than free iron, but the process of the human body's own chelation is not easy. Therefore, the iro...
