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 carotenoid feed additive, which is a naturally occurring pigment found in certain plants and microorganisms.
Citranaxanthin's primary mode of action is through deposition into the tissues of animals, particularly in the egg yolks of poultry, where it enhances color.
This enhancement occurs as citranaxanthin integrates into the lipid structures, contributing to a deeper yellow or orange hue due to its strong pigmenting properties.
The primary application of citranaxanthin is in the poultry industry, where it serves as an additive in feed formulations.
Citranaxanthin's use is crucial for producers seeking to optimize the visual appeal of egg yolks, which is a key quality parameter for consumer satisfaction and marketability.
Citranaxanthin's role is not limited to aesthetic improvements; it also reflects the dietary quality and welfare standards of the feed provided to poultry.
Additionally, its use must comply with regulations governing feed additives, ensuring no adverse effects on animal health or human consumers.
Citranaxanthin, with the CAS number 3604-90-8, is a carotenoid pigment primarily found in certain algae and plants.
Citranaxanthin is characterized by its vibrant yellow to orange color, which is a result of its conjugated double bond system that allows for light absorption in the visible spectrum.
Citranaxanthin is known for its antioxidant properties, which can help protect cells from oxidative stress.
Citranaxanthin is also of interest in the food and cosmetic industries due to its potential as a natural colorant.
In terms of solubility, Citranaxanthin is generally soluble in organic solvents but less so in water, which is typical for many carotenoids.
Citranaxanthin's stability can be affected by factors such as light, heat, and oxygen, necessitating careful handling and storage to maintain its integrity.
Additionally, citranaxanthin may play a role in photosynthesis and has been studied for its potential health benefits, including anti-inflammatory and immune-boosting effects.
