E160ai - Bêta-carotène

Origin

Beta-carotene (E160ai) is a naturally occurring carotenoid pigment found in many plants, fruits, and vegetables, giving them their characteristic orange or yellow color. It can be extracted from these natural sources or produced synthetically through chemical synthesis or microbial fermentation. Natural sources include carrots, sweet potatoes, spinach, and kale. The synthetic form is chemically identical to the natural form.

Usage

Beta-carotene is widely used as a food coloring agent to impart a yellow-to-orange hue to various food products. Beyond its coloring properties, beta-carotene is a provitamin A carotenoid, meaning the body can convert it into vitamin A (retinol), an essential nutrient for vision, immune function, and cell growth. It is added to foods such as margarine, cheese, beverages, baked goods, and processed foods. It is also available as a dietary supplement.

Side Effects

Beta-carotene is generally considered safe for consumption at levels typically used in food. The Scientific Committee on Food established an acceptable daily intake (ADI) of 0-5 mg/kg body weight for beta-carotene from all sources. Excessive consumption of beta-carotene can lead to carotenemia, a harmless condition where the skin turns yellow-orange due to the accumulation of beta-carotene in the subcutaneous fat. This condition is reversible upon reducing beta-carotene intake. There are no known serious adverse health effects associated with high beta-carotene intake from food sources. However, some studies have suggested that high doses of beta-carotene supplements may increase the risk of lung cancer in smokers; therefore, smokers should exercise caution when taking beta-carotene supplements.

Regulatory Status

Beta-carotene (E160ai) is approved for use as a food additive in many countries, including the United States, the European Union, and Canada. In the EU, it is listed under the E number E160ai. The FDA considers beta-carotene as Generally Recognized As Safe (GRAS) when used in accordance with good manufacturing practices. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has also evaluated beta-carotene and established an ADI.
