Detailed Description:
Cas No. :3351-86-8 he raw materials used in the extraction of fucoxanthin products by "jie jing" are kelp, crabgrass and hijiki. In the production process, ethanol is used as the extraction agent instead of methanol and acetone.
"Jie jing" products have oil, powder agent two forms, according to the different purity of the product, the appearance of orange yellow, reddish brown.
Fucus Huang Suyi soluble in organic solvents such as ethanol, insoluble in water, easy oxidation by air, light, heat sensitive and unstable, the product must be vacuum packaging or filling nitrogen, avoid light, avoid high temperature, low temperature (below 5 ℃) to store, to use up as soon as possible after opening the package.
If you do not use up to continue to save, need to exhaust the air packaging and full of nitrogen preservation.
