Problems solved by technology

But EDTA, CaNa 2 The application of EDTA drugs is limited because they will cause the loss of calcium ions in the body and interfere with the metabolism of other metal elements, and cause the redistribution of lead in the brain, and at the same time require intravenous injection; BAL, DMSA, etc. Dimercapto drugs have poor stability, are easily oxidized, and are inconvenient to use and have high treatment costs; most other lead-expelling preparations have certain side effects and poor selectivity. Iron etc. are also obviously excreted
Some lead-expelling preparations such as traditional Chinese medicines and nutrients have less toxic and side effects, but the lead-expelling effect is not good

Embodiment 1

[0010] Weigh 5.0g of low-molecular-weight carboxymethyl chitosan, 2.0g of oligogalacturonic acid and 3.0g of oligomeric gulururonic acid, add them to 1000mL water, stir and dissolve at room temperature, and use a 300-mesh sieve Filtrate to remove insoluble impurities, then precipitate with 95% ethanol, dehydrate, vacuum-dry at 40°C, and grind to 80 meshes to obtain the combined oligosaccharide of the present invention.

Embodiment 2

[0012] Weigh 3.5g of low-molecular-weight carboxymethyl chitosan and 6.5g of oligomeric guluronic acid and add them into 1000mL of water to obtain it according to the operation in Example 1.

Embodiment 3

[0014] Weigh 7.0 g of oligogalacturonic acid and 3.0 g of oligoglucuronic acid respectively, add them into 1000 mL of water and operate as in Example 1.

Abstract

A composite oligose used as the food additive or health-care food for removing the ions of heavy metals selectively is prepared from carboxymethyl chitosan and / or oligogalacturonic acid and / or oligoguluronic acid through proportionally dissolving, filtering depositing in alcohol, baking, mixing and pulverizing. Its advantages are high effect and no-toxic by-effect.

Description

technical field [0001] The invention relates to a health food, in particular to a combined oligosaccharide capable of selectively removing heavy metal ions, its preparation method and its application in food. Background technique [0002] With the continuous acceleration of industrialization and urbanization, the pollution of heavy metal ions has become one of the risk factors that seriously endanger human life and health in modern civilized society, among which lead pollution is the most serious threat to human life and health. Bad habits such as industrial waste gas, vehicle exhaust, lead-containing products, food and dust, and long-term smoking are all important sources of lead pollution. After lead is absorbed into the human body, because it can accumulate in various tissues and organs of the human body, it is easy to accumulate in bones (accounting for about 85-90% of lead accumulated in the body), thereby causing damage to the bone marrow, hematopoietic system and nerv...
