Estimating Caffeine Content in Matcha Powder

We are conducting R&D testing to verify the caffeine content in decaffeinated matcha powder. The goal of this project is to ensure the product meets low-caffeine standards suitable for the U.S. market. We require precise analysis from a China-based laboratory to confirm the caffeine level per gram, using reliable laboratory methods. The results will support product labeling, quality assurance, and regulatory compliance.
