Product Properties
Apoester is an oxygen-containing apocarotene compound among carotenoids. In the food industry, it is mainly used for the coloring of edible oil, margarine, jam, jelly and beverage products. In the feed industry, it is widely used in broiler poultry, especially the coloring of broiler skin, feet, fat and poultry egg yolk. It has a high precipitation rate in the target tissue and is a highly effective carotenoid additive.
The coloring principle of apo fat
• The unsaturation of conjugated double bonds in macromolecules is the chemical basis for color generation.
• The substance used for coloring absorbs a certain amount of light to produce color, and the molecular structure of the colorant determines the range of light absorption.
• Chromophoric group: The structure of the colorant substance must contain a chromogenic group, the common ones are carbon-carbon double bond, carboxyl group, ester group and ketone group.
• Auxochrome group: Some groups cannot produce color by themselves, but when connected with a conjugated system or a chromophore, the absorption wavelength can be shifted to the long-wave direction.
• Coloring of poultry products is the result of the interaction of chromophores and auxochromes.
