Green coffee bean extract standardised for chlorogenic acid, in decaffeinated and standard grades, plus high-purity natural caffeine.
Chlorogenic-acid-rich green coffee extracts and natural caffeine — backward-integrated to the group's own Robusta estate.
Green coffee bean extract is one of CTA's most strategically integrated products. The unroasted bean of Coffea robusta is rich in chlorogenic acids (CGA), and CTA extracts and standardises this to 45–50% CGA by HPLC, with grades available at both standard and reduced caffeine levels.
CTA's green coffee programme runs end-to-end: an optimised extraction protocol, a resin-adsorption purification route for high-CGA grades, and recovery of natural caffeine at up to 98% purity as a co-product. Critically, Robusta coffee is the primary crop of the group's own Rawther Plantations estate — making green coffee a genuinely backward-integrated, traceable product line.
CTA supplies Green Coffee Bean across multiple grades. Custom specifications are developed against a documented buyer requirement.
| Botanical source | Coffea robusta — green (unroasted) bean |
| Appearance | Light-brown to brown fine powder |
| Standardisation | 45–50% chlorogenic acids (CGA) |
| Caffeine | Standard and decaffeinated (<5%) grades |
| Test method | HPLC |
| Loss on drying | Not more than 5% |
| Heavy metals | Conforms to USP / regulatory limits |
| Microbiology | TPC ≤10,000 cfu/g; yeast & mould ≤500 cfu/g; E. coli & Salmonella absent |
| Pesticide residues | Within IP / USP / EP limits |
| Solubility | Water-dispersible grades available |
All values are typical specifications and are confirmed batch-by-batch on the Certificate of Analysis. Custom specifications can be developed against a buyer's documented requirement. Values are indicative and to be confirmed by CTA's technical team before publication.
CTA operates a full green-coffee process chain, documented from optimisation through purification:
A documented process library is what separates a speciality product from a commodity — it makes grades reproducible and lets CTA develop a custom specification with confidence.

Our standard green coffee extract is standardised to 45–50% chlorogenic acids by HPLC. Higher-purity grades are produced via a resin-adsorption route, and custom CGA-to-caffeine ratios can be developed.
Yes. CTA produces a CGA-rich decaffeinated grade with caffeine reduced below 5%, suitable for caffeine-free metabolic formulations.
Robusta coffee is the primary crop of the group's own Rawther Plantations estate, making green coffee extract a traceable, backward-integrated product line.
