β-carotene (C40H56), one of the carotenoids, is an orange-yellow fat-soluble compound, which is the most ubiquitous and stable natural pigment in nature. Belongs to a family of natural chemicals such as carotene or carotenoids. It is found in abundance in plants, giving fruits and vegetables their rich yellow and orange hues. The appearance of the pure product is reddish purple to dark red crystalline powder, with a slightly specific odor. The dilute solution of β-carotene is orange-yellow, and is easily soluble in organic solvents such as dichloromethane, chloroform, and carbon disulfide. When the concentration of the solution increases, it turns orange, and it can be slightly reddish due to the polarity of the solvent. Instability to oxygen, heat and light. It is more stable in weak base. β-carotene is widely used in food industry, feed industry, medicine and cosmetics industry. Methods for obtaining β-carotene include natural extraction, chemical synthesis, and microbial fermentation.
