説明
Bixin [CAS: 6983-79-5] (CI Natural Orange 4; CI 75120) is found in the seed of the plant Bixa orellana, native to India. Later it was found growing in South America, where the Indians used the red dye from the seeds as a body paint. An extract of the seeds appears on the market as annatto. This extract is used in coloring butter, margarine, and cheese such as Leicester cheese. In Mexican and South American cuisine, it finds special use as a flavor and coloring matter. Annato is available as an aqueous solution, as an oleaginous dispersion, and a spray-dried powder.

使用
Bixin is a carotenoid that is the main coloring component of annatto.
it is obtained from the bixa orellana tree. bixin is soluble in fats and
oils and the produced color is found in the fat fraction of the food.
it has a yellow hue, very good oxidation stability, fair light stability,
and good heat stability, but it is poor at very high temperatures,
such as above 125°c. one part bixin is equivalent to 1.5 parts caro-
tene. it is used at 0.5–10 ppm in finished foods, such as margarine,
salad dressings, popcorn oil, and baked goods. it is also termed
annatto extract. see annatto.
定義
ChEBI: A carotenoic acid that is the 6'-monomethyl ester of 9'-cis-6,6'-diapocarotene-6,6'-dioic acid.
一般的な説明
Bixin is a methyl ester of a dibasic fatty acid. On treating with alkali, it is hydrolyzed to form water soluble norbixin. It is obtained in pure form from annatto seeds. Bixin is a carotenoid and estimated as yolk and skin pigmenter.
純化方法
Crystallise bixin from Me2CO (violet prisms) [Pattenden et al. J Chem Soc (C) 235 1970]. [Beilstein 2 III 2020, 2 IV 2455, H 30 110.]
