Frequently Asked Questions
What is lutein 5%?
Lutein Extract Powder 5% is a carotenoid extract standardized to 5% lutein (xanthophyll, CAS 127-40-2, formula C40H56O2), typically derived from marigold. It serves as a natural yellow colorant and food additive and as a xanthophyll pigmenting and nutrient ingredient for feed, food, and supplement formulations.
What is the difference between 5% and 0.5% lutein powder?
Both supply the same lutein carotenoid (CAS 127-40-2); the percentage is the standardized lutein content by weight. The 5% grade is ten times more concentrated than a 0.5% grade, allowing lower inclusion rates for the same xanthophyll dose. Calculate dosing from the assay on the CoA.
What is lutein 5% powder used for?
It is used as a natural yellow food colorant, as a xanthophyll pigmenter for poultry and aquaculture feed, and as a lutein source in nutrient/supplement formulations.
What is the molecular formula and CAS number of lutein?
Lutein has the molecular formula C40H56O2 and carries CAS 127-40-2. Reference these identifiers, together with the standardized assay percentage, on the Certificate of Analysis when matching to your formulation.
Does RawSource supply lutein 5% powder in bulk?
RawSource distributes lutein extract powder in bulk for food-colorant, feed, and supplement manufacturers. A Certificate of Analysis confirming lutein assay and a Safety Data Sheet ship with each order; request both with a bulk quote for your target volume.
