Beta-apo-8′-carotenal sources, health risks

Tuesday, October 17, 2017 by

Beta-apo-8′-carotenal (also known as apocarotenal) is a carotenoid that can be found in cheese slices, vegetable pulp such as spinach, and citrus fruit skin, most commonly in oranges and tangerines. It is orange to red in color and is used in foods, pharmaceuticals, and cosmetic products as a coloring agent. Beta-apo-8′-carotenal is a precursor to vitamin A and has no known adverse health effects, but may cause vitamin A toxicity if taken in high quantities.

Harmful effects that may be caused by beta-apo-8′-carotenal

Beta-apo-8′-carotenal is a source of vitamin A and has no known adverse health effects except when taken in excessive doses. In a study published in InChem, groups of rats received different levels of carotenal five days per week for 34 weeks, and exhibited no adverse effects on the body weight, liver and kidney function, and general health. The short-term experiment also used male and female dogs, administered with carotenal daily for 14 weeks. The results showed no significant effect— all animals remained healthy. In a long-term experiment, rats administered with different levels of beta-apo-8′-carotenal for two years also showed no adverse effect in any generation and did not result in an increase in vitamin A.

The study concluded with 0-5 mg/kg estimate of acceptable daily intake for man.

Body systems harmed by beta-apo-8′-carotenal

While there are no known health effects, beta-apo-8′-carotenal is harmful to aquatic life with long-term effects and may cause allergic skin reaction in some instances.
