Combined holoside as well as preparation method and application

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...
