Analysis performed on this extract by an independent third-party food testing laboratory, Bengaluru. Report VRB/FD/2608/01-0019, issued 12 August 2026.
Ginger oleoresin is bought and sold on one number: total gingerols. This lot assays at 20.40 g/100g, meeting the 20% gingerol grade the trade specifies — and it gets there without a chemical solvent anywhere in the process.
The bulk of it is 6-gingerol at 18.32 g/100g, the compound that carries ginger's pungency and the one most formulations are built around.
Gingerols, g/100g. Method: FSSAI Manual for Spices & Condiments.
A further 8.26 g/100g of shogaols sits alongside the gingerols, adding the sharper, warmer edge of the ginger profile.
The dried rhizome this lot came from assayed at 2.02% gingerols. The finished oleoresin assays at 20.40 — a tenfold concentration of the active fraction into a pourable, dosable extract.
A yellow, thick liquid with the full pungent-aromatic profile of the fresh rhizome. Because the aromatics are never distilled off, the top notes stay with the resin instead of being lost to the still.
Before a single kilogram entered the extractor, the harvested lot was sent to an independent third-party food testing laboratory in Bengaluru and screened against the full FSSAI and EU contaminant panel. Every result came back clean.
Screened to EC No. 396/2005. Not a single residue was quantifiable — the result EU buyers need before a shipment moves.

This oleoresin begins as Rio De ginger grown at a single farm in Jabagere, Karnataka, lifted from one harvest and kept as a single identified lot from the field to the sealed drum.
Nothing was blended in. There is no pooled market material behind this batch and no second origin to disclose, which means the chain below is the whole story: four steps, each dated, each documented.
Extraction is carried out with supercritical carbon dioxide at a dedicated scCO₂ facility in Jigani, Bengaluru. Carbon dioxide is brought above its critical point, where it behaves as a solvent, draws the aromatic and resinous fraction out of the milled rhizome, and is then simply returned to gas and recovered.
The consequence for a formulator is a short list: no hexane, no ethanol, no acetone and no chemical solvent residue to declare or test for. Working temperatures stay low, so the volatile top notes that steam distillation drives off are retained. Each run is separated into two fractions — a lighter essential oil and a heavier oleoresin — and every fraction is weighed, coded and logged against the trial it came from.
A standardised 20% gingerol extract dose-controls far more precisely than ground ginger, and disperses cleanly into flavour systems.
Known gingerol and shogaol figures plus a clean contaminant history make this straightforward to qualify for capsule and softgel formats.
Full pungent-aromatic profile at low inclusion rates, with none of the batch-to-batch drift of a ground spice.
CO₂-extracted with no chemical solvent in the process and none to declare on the finished product.
We ship evaluation samples of Rio De ginger oleoresin with the full documentation set, so your R&D and QA teams can assess the material and the paper trail at the same time. Commercial quantities are produced to order against the same origin and the same process.
