Marigold-derived lutein for eye-health and natural-colour applications — supplied as esters, free lutein and purified crystal.
Lutein esters, free lutein and high-purity lutein crystal from marigold flowers.
Lutein is a carotenoid extracted from the petals of the marigold flower (Tagetes erecta) and one of the most important ingredients in the eye-health category. CTA processes marigold oleoresin into a graded family of lutein products.
Our process library covers the full route: isolation of lutein esters from marigold oleoresin, an ethanol-based isolation method, saponification to free lutein, and purification to an 80% lutein grade with a defined crystal specification. This allows CTA to supply either an ester grade for stability or a free-lutein grade for bioavailability, depending on the buyer's formulation.
CTA supplies Marigold across multiple grades. Custom specifications are developed against a documented buyer requirement.

| Appearance | Orange to dark-orange powder or crystalline solid |
| Standardisation | Ester, free-lutein and 80% purified grades |
| Test method | HPLC / UV |
| Co-carotenoid | Zeaxanthin present per natural ratio |
| 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 |

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's lutein programme is built on a documented isolation and purification route:
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.
Statements describe traditional use and the role of the active in normal body function. They are structure–function statements and not claims to diagnose, treat, cure or prevent any disease.
Eye-health and macular-support supplements; softgels, capsules and tablets.
Natural yellow-orange colour and carotenoid fortification.
Lutein for vision-support fortified formats.
Carotenoid actives for antioxidant and vision blends.
Lutein from marigold is permitted under FSSAI and is widely accepted internationally as a nutrient and as a natural colour. Grade documentation and dossiers are provided on enquiry.
Note: grades, marker percentages and regulatory status are indicative and to be confirmed by CTA's technical and regulatory team before publication.
Lutein esters are the naturally occurring form in marigold and are more stable in storage. Free lutein is produced by saponification and is formulated where bioavailability is the priority. CTA supplies both.
CTA produces ester and free-lutein grades and a purified 80% lutein grade with a defined crystal specification. Custom assays are developed on request.
Yes. CTA's lutein is extracted from marigold (Tagetes erecta) flowers, supporting natural-source and clean-label positioning.
