Beta-apo-8-carotenal

Beta-apo-8-carotenal is an orange-red carotenoid chemically related to beta-carotene (E160a). It occurs naturally in small amounts in spinach, citrus peel, and some other plants, but food-grade material is synthetically produced for consistency and cost. It is used as an orange-to-red colourant in beverages, cheese, margarines, and other fat-containing foods where its lipophilic nature ensures good distribution.

JECFA's ADI is 5 mg per kilogram body weight per day, established in 1974. Like other carotenoids, beta-apo-8-carotenal is converted in the intestinal wall and liver to retinol (vitamin A), contributing to vitamin A nutritional status. This pro-vitamin A activity is generally considered beneficial; however, very high intakes of preformed vitamin A can be toxic, so the ADI accounts for this pathway.

Beta-apo-8-carotenal is approved in the EU, and generally permitted in most global food markets. It carries a natural-origin positioning given its structural relationship to beta-carotene and its presence in food plants. There are no specific safety concerns for healthy adults at typical dietary exposures from food additive use. Pregnant women who are already supplementing vitamin A should note that cumulative intake from all vitamin A sources — including carotenoid food colours — contributes to total vitamin A status.
