Product Details

As a typical carotenoid, β‑Carotene occurs abundantly in nature and ranks among the most stable natural pigments. This fat‑soluble substance exists in the form of orange‑yellow crystalline powder or lustrous rhombohedral crystals. It is mainly extracted from green plants as well as yellow‑orange fruits. Its diluted solution displays an orange‑yellow to yellow hue; the color will grow deeper along with rising concentration levels. Subject to the polarity difference of dissolving solvents, slight reddish color shift can be observed. Possessing antioxidant capacity and the capability to generate vitamin A, β‑Carotene finds broad deployment within food goods, cosmetic formulas and nutritional supplement products.
