Chemical properties: It is a strong antioxidant, but relatively unstable when exposed to high temperatures, ultraviolet radiation, and oxygen.3. Nutritional properties: β-Carotene is an important nutrient for the human body and can be converted into vitamin A, helping to maintain vision, promote growth, and support immune system function.Methods of preparation:1. Natural extraction: Extracting and purifying β-Carotene from natural sources such as carrots.2. Synthesis: Preparing β-Carotene from suitable raw materials through chemical synthesis.Safety information:High doses of β-Carotene intake may cause yellowing of the skin (carotenemia), but it does not have serious effects on human health.
