Popular questions
What is the e number of norbixin?
E160b(ii) (also written as E160BII).
How common is bad tast with bixin?
Off-taste from bixin is uncommon at typical use levels; annatto’s flavor is usually mild and not noticeable. Bitterness or earthy/painty notes are more likely if overdosed, oxidized/aged, or used in very neutral-flavored matrices.
How is bixin used in food?
It’s an oil-soluble annatto carotenoid used to give yellow–orange color, especially in cheeses, margarines, snacks, and other fat-containing foods. For water-based products, manufacturers typically use the saponified, water-dispersible form (norbixin).
How to solubilize bixin?
Dissolve it in warm vegetable oil or other food-grade nonpolar carriers (often 40–60°C), or formulate it as an oil-in-water emulsion with suitable emulsifiers while protecting from light and oxygen. For water systems, convert it to norbixin via mild alkaline saponification and then neutralize to maintain dispersion.
How to test for bixin in spices?
Extract with hexane/acetone (or ethanol) and screen by UV–Vis absorption around 470–480 nm or by TLC/HPTLC against a bixin standard, noting potential interference from other carotenoids. For specific identification and quantification, use RP-HPLC with diode-array detection (or LC–MS) and compare retention time and spectrum to a certified standard.
How to test for bixin on spices?
Swab the surface with a solvent-wetted swab (hexane/acetone or ethanol), extract the swab, and analyze as above by UV–Vis/TLC for a quick screen and HPLC-DAD (or LC–MS) for confirmation. Simple color spot tests can indicate annatto, but chromatography against a bixin standard is needed for definitive results.
