COLORANT | [Uses]
Annatto is a color source of yellowish to reddish-orange color
obtained from the seed coating of the tree bixa orellanna. the oil-
soluble annatto consists mainly of bixin, a carotenoid soluble in fats
and oils with the color which is produced in the fat portion of the
food. it has a yellow hue, very good oxidation stability, fair light
stability, and good heat stability, but it is unstable above 125°c. the
water-soluble annatto is norbixin (the product resulting when bixin
is saponified and the methylethyl group is split off) which is dis-
solved as a potassium salt in lye. it is readily soluble in aqueous
alkalis with the coloring occurring in the protein and starch fraction
of the food. it has a yellow to orange hue and precipitates in most
acid foods. the usage level is 0.5–10 ppm in the finished food. it is
used in sausage casings, oleomargarine, shortening, and cheese. | [EPA Substance Registry System]
