β-Carotene CAS#7235-40-7
β-carotene is a member of the carotenoid family, a naturally occurring pigment that is both widespread in nature and highly stable.It has distinct physical properties: it is an orange-yellow fat-soluble compound, typically appearing as glossy rhombohedral crystals or crystalline powder. Its natural sources are primarily from foods like green plants, as well as yellow and orange fruits.In terms of its solution characteristics, dilute β-carotene solutions range in color from orange-yellow to yellow. As the concentration increases, the color deepens to orange; depending on the polarity of the solvent used, the solution may also take on a slight reddish tint.

β-Carotene CAS#7235-40-7 Application
β-Carotene is a well-recognized antioxidant. By definition, antioxidants are substances that may shield your cells from free radicals—compounds linked to the development of health issues like heart disease and cancer.Its practical uses span multiple areas. In the food industry, it acts as a coloring agent: added to margarine, cheese, and pudding to achieve the desired hue, it also functions as an additive for creating yellow-orange shades.Beyond this, beta-carotene serves as a precursor to both carotenoids and vitamin A, delivering several health benefits. It helps protect the skin from dryness and flaking, slows down cognitive decline, and contributes positively to overall human health.
