07. Manufacturing Process & Engineering Control

AIHerba’s L-Theanine is produced via Enzymatic Microbial Fermentation. This process avoids the harsh solvents and irregular isomeric ratios typical of synthetic alternatives. By implementing multi-stage ultrafiltration, we achieve 100% cold-water solubility and a clear, odorless finish—essential for functional beverages.

09. Industrial Application Compatibility

Functional Beverages

Clear, odorless isolate ideal for RTD tea and relaxation shots.

Nutraceutical Stacks

High bulk-density powder for high-speed automated capsule filling.

11. Stability & Transport Engineering

Risk: Hygroscopic Clumping

Highly purified L-Theanine can aggregate in high-humidity transit.

Solution: Induction-sealed PE drums with desiccant-integrated foil liners.

17. Technical Procurement FAQ

Q1: What is the difference between Synthetic and Fermented L-Theanine?

Synthetic L-Theanine is cheaper but often contains D-isomers which are not present in tea leaves. AIHerba’s fermented L-Theanine is bio-identical, ensuring higher biological activity and a cleaner regulatory profile for premium brands.

Q2: Is your L-Theanine suitable for clear functional beverages?

Yes. We use membrane purification to remove proteins and lipids, resulting in a colorless and transparent solution that won’t affect the aesthetics of your RTD formulation.

Q3: Do you support DDP shipping to the USA and Europe?

Yes, AIHerba provides full DDP (Delivered Duty Paid) logistics, handling all customs clearance and duties for a friction-free B2B sourcing experience.
