D-Glucopyranose, 1,2,3,4,6-pentakis[3,4-dihydroxy-5-[(3,4,5-trihydroxybenzoyl)oxy]benzoate] Use and Manufacturing

Methods of Manufacturing

Using gallnut as raw material, it is extracted with ethanol or ethyl acetate or ethanol-ether leaching method, purified by chromatographic method to remove pigment and resin, then concentrated and dried in vacuo to form a powder. The yield is about 50% to 70%. It is obtained by squeezing raw persimmons repeatedly with a small amount of water. It is called "Tannin of Kaki". It is a pale yellow liquid of 5.4-7.9%, containing 4.7%-6.3% tannin, about 2.4% sugar, and liquid. The pH is 3.2～3.9.

Uses

As a protein adsorbent, my country~"s regulations can be used for fruit wine and low-alcohol wine, according to the production needs to be used in an appropriate amount.
