What is "apocarotenal"

Apocarotenal, or trans-β-apo-8'-carotenal, is a carotenoid found in spinach and citrus fruits. Like other carotenoids, apocarotenal plays a role as a precursor of vitamin A, even though it has 50% less pro-vitamin A activity than β-carotene. The empirical chemical formula for apocarotenal is CHO.

Apocarotenal has an orange to orange-red colour and is used in foods, pharmaceuticals and cosmetic products. Depending on the product forms, apocarotenal is used in fat based food ( margarine, sauces, salad dressing), beverages, dairy products and sweets. Its E number is E160e and it is approved for usage as a food additive in the USA, EU and Australia and New Zealand.
