Green coffee bean extract (Chlorogenic acid)

Thovek supplies green coffee bean extract from the unroasted seed of Coffea canephora Pierre ex A. Froehner (robusta) and Coffea arabica L., family Rubiaceae, standardised on total chlorogenic acids. The reference marker is chlorogenic acid, 5-O-caffeoylquinic acid, C16H18O9, molecular weight 354.31, CAS 327-97-9, but the label figure is a family total rather than a single compound: green beans carry a set of caffeoylquinic, dicaffeoylquinic and feruloylquinic acid isomers, of which 5-CQA is the largest single contributor. Roasting destroys much of that fraction, which is why the extract is made from green, unroasted beans by hot water or water-ethanol extraction, vacuum concentration and spray drying, with no roasting step anywhere in the process. The headline commercial grades are 45% and 50% total chlorogenic acids, with 10-20% grades used where cost or beverage taste dominates and 60% available for tablet and capsule work where dose per unit matters. Specify the analytical method explicitly on your purchase specification: a UV reading taken against a single 5-CQA standard returns a higher number than an isomer-resolved HPLC assay, so "CGA 50%" means two different things depending on which was run, and a label claim built on the UV figure may not survive a third-party retest. Caffeine is the other variable - it travels with the chlorogenic acids, and reported caffeine across commercial green coffee extracts spans a very wide range, so a declared per-batch HPLC caffeine figure belongs on the CoA of any finished product carrying a caffeine statement or a caffeine-free claim. Sourcing and compliance. Green coffee is an ochratoxin A risk commodity, so incoming beans and the finished extract are tested to the buyer's destination limit alongside heavy metals, pesticide residues and microbiology. The extract is plant-derived, vegan and vegetarian, and contains no milk, egg, soy, fish, crustacean, peanut, tree nut, sesame or gluten-bearing input and no bovine, porcine or marine material; where a carrier is required it is maize-derived maltodextrin, declared on the specification. India's own predominantly robusta crop from Karnataka, Kerala and Tamil Nadu supports short and traceable supply chains, and every consignment ships with a CoA, MSDS, allergen and non-GMO declarations, and halal and kosher certificates where required.
