Citranaxanthin is a carotenoid pigment used as a food additive under the E number E161i as a food coloring.
There are natural sources of citranaxanthin, but it is generally prepared synthetically.
Citranaxanthin is used as an animal feed additive to impart a yellow color to chicken fat and egg yolks.
Uses:
Citranxanthin is an antioxidant β-carotene (C184250) found in plants such as tomatoes, kale and papaya, as well as in the yolks of fertile chicken eggs.
Citranaxanthin (citranaxanthin) can replace canthaxanthin over the entire dosage range at a constant factor of 1.5:1, resulting in the same pigmentation efficiency.
Definition
ChEBI: An apo carotenoid compound arising from oxidative degradation of the beta,beta-carotene skeleton at the 1'- and 6'-positions.
Purification Methods
Purify it by chromatography on a column of 1:1 MgO and HyfloSupercel (diatomaceous filter aid).
Crystallise it from pet ether.
Store it in the dark under N2 or Ar at 0o. Crocetin diethyl ester (8,8'-diapo-
Citranaxanthin is an apo carotenoid compound arising from oxidative degradation of the beta,beta-carotene skeleton at the 1'- and 6'-positions.
Citranaxanthin has a role as a food colouring.
Citranaxanthin is an apo carotenoid and an enone.
Citranaxanthin is a natural product found in Gallus gallus and Dolabella auricularia with data available.
Citranaxanthin is a powder formulation which swells slowly in cold water, more rapidly in warm water (40°C) and finally disintegrates to form a dispersion.
Citranaxanthin contains at least 10% citranaxanthin (5’, 6’-dihydro-5’-apo-18’-nor-ß-carotene-6’-one).
Citranaxanthin is a red carotenoid and it is used exclusively in poultry rations in order to impart redness to egg yolks.
Citranaxanthin, a close relative of the yellow pigment C-30 ester, is efficiently assimilated and deposited in yolks, where it contributes to the consumer appeal of eggs and egg products.
Used in conjunction with yellow pigments, citranaxanthin increases yolk colour intensity to meet market demands for golden-orange yolks.
Roles Classification
Biological Role(s): food colouring
A food additive that imparts colour to food.
In European countries, E-numbers for permitted food colours are from E 100 to E 199, divided into yellows (E 100-109), oranges (E 110-119), reds (E 120-129), blues and violets (E 130-139), greens (E 140-149), browns and blacks (E 150-159), and others (E 160-199).

Definition
Citranaxanthin is an apo carotenoid compound arising from oxidative degradation of the β,β-carotene skeleton at the 1'- and 6'-positions.
Citranaxanthin belongs to the class of organic compounds known as triterpenoids.
These are terpene molecules containing six isoprene units.
Citranaxanthin is a colouring agent used in animal feeds, to colour the fat of poultry and the egg-yolks of laying hens.
Citranaxanthin has vitamin A activity.
