Quality control

Living with the philosophy and policy of “quality is the most important for the long-standing business”, we carry out rigorous quality checks throughout the manufacturing process at every step, from the selection of raw materials to the testing the final products.

These checks mainly include:

-Identification 
-Assay 
-Microbiologic
-Pesticide residues 
-Solvent residues
-Heavy metals
-Aflotoxins 
-PAHs

For the natural products like herbs and extracts, our quality control involves not only full-item analysis to specifications, but also botanical origin identification batch-to-batch consistency and effectiveness potency, which are important factors to our customers who take our ingredients into their products.
