Embodiment Construction

[0023] 1. Take 0.05g of sodium selenite or sodium biselenite and dissolve it in water, then evenly spray it into 5g of chitosan powder or chitosan oligosaccharide powder to make it moist, and finally spray vitamin C solution while stirring until The red color of the mixture does not change, and the product is obtained by vacuum drying to remove moisture.

[0024] 2. Take 0.05g of sodium selenite or sodium hydrogen selenite and dissolve it in water, add an aqueous solution containing 5g of chitosan or chitosan oligosaccharide under stirring, then add vitamin C or its solution until the red color of the reaction solution does not change, and depressurize Distillation to remove moisture that is the product.

[0025] 3. In embodiments 1 and 2, starting materials can be used to prepare sodium selenite or sodium biselenite solution earlier, and the reaction product does not need to be separated, and is directly used to prepare chitin nano-selenium. This is to use selenium dioxide, ...

Abstract

A chitin-nano selenium compound for regulating immunity, delaying sanility and preventing cancer and cardiovascular disease is prepared from chitin (chitosan, water-soluble chitosan, or chitoligose) and Se compound through reaction.

Description

technical field [0001] The invention relates to a nutritional health food and a preparation method thereof, specifically chitin nano-selenium and a preparation method thereof. Background technique [0002] Chitin, also known as chitin, chitin, chitin, polyhexanoylglucosamine, etc., is a linear amino polysaccharide that maintains and protects the bodies of crustaceans and microorganisms. Chitin widely exists in the cells of lower plant fungi and algae, the shells of arthropod shrimp, crabs, fly maggots and insects, the shells and cartilages of shellfish and molluscs (such as squid and cuttlefish), and the cell walls of higher plants, etc. Its annual biosynthetic resources are as high as 10 billion tons, which is the second largest biological resource on the earth after plant fibers. Among them, the production of marine organisms is more than 1 billion tons, which can be said to be an inexhaustible natural resource. Resources, known as the third largest biological resources a...
