Plant Part Used : Root & Rhizome CAS# : [501-36-0] Specification: 20%, 50%.98%, 99% Resveratrol manufacturing details : 1, There are 5 pivotal step during the processing of Resveratrol: A) Raw Material Original cultivation area of the Giant Kotweed is very important , just few mountains growes good quality raw materials . Resveratrol content of raw material decrease down when harvested during May to October. B) Fermentation Enzyme Choosing Resveratrol transformation ratio is determined mostly by the Fermentation Enzyme . Good fermentation enzyme can bring 98% transformation , while normal enzyme can just make 80% transformation , which will directly effect the manufacturing cost . C) It’s easy way to produce 20% Resveratrol , and from 20% to 40% , but there is a key step from 20% to 50% , and it will take high lost during 50% content producing , so that’s why most manufacturer won’t supply this 50% specification and there is a big gap in this 50% resveratrol market . D) Manufacturing processing from 20% to 98% needs high-tech base . Lots of herb extract supplier in the world can’t produce this 98% Resveratrol . E) It’s very hard to control the procedure to make the 98% product into pure white color . Few 98% Resveratrol manufacturer can supply pure white color products . 2, Our obvious big superiority on this 98% Resveratrol’s processing . We are also professional Tea extract supplier . There are some same key procedures between Resveratrol and Tea products Catechins , because both Resveratrol and Catechins are very sensitive with temperature , high temperature will cause decrease of their content , color , aroma and taste. So we have obvious big superiority on this 98% Resveratrol’s processing .
