Lutein

Lutein is a xanthophyll carotenoid, an oxygen-containing pigment found in green leafy vegetables and in the petals of marigold, Tagetes erecta, its usual commercial source. Nustras supplies lutein as a marigold-derived ingredient, in crystalline, oil-suspension or powder grades according to specification, used as a colouring and functional ingredient in supplements, foods and feed.

Lutein is formulated into softgels, capsules, tablets and gummies, into functional beverages and fortified foods, and into pet food and poultry feed as a yolk and skin pigmenter. Oil-suspension grades suit softgels; powder grades suit tablets and dry blends.

Lutein is an orange-yellow to red-orange crystalline powder or oil suspension, sensitive to light, heat and oxygen. The CAS number is 127-40-2, the molecular formula C40H56O2 and the molecular weight 568.9. Each lot is standardised to specification, lutein content is confirmed by HPLC or UV-visible spectrophotometry, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies lutein in bulk commercial quantities, in light-protected sealed packaging, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Lutein is an accepted supplement and colouring ingredient in major markets; buyers confirm the permitted level and labelling for their application.
