β-carotene (C40H56) is one of the carotenoids and is an orange-yellow fat-soluble compound. It is the most ubiquitous and most stable natural pigment in nature. Belong to natural chemicals. It is abundant in plants, giving fruits and vegetables a full yellow and orange color. The appearance of the pure product is red-purple to dark red crystalline powder with a slight peculiar smell. The dilute β-carotene solution is orange-yellow and easily soluble in organic solvents such as methylene chloride, chloroform, and carbon disulfide. When the concentration of the solution increases, it becomes orange, because the polarity of the solvent may be slightly red. It is unstable when exposed to oxygen, heat and light. It is more stable in weak bases.
Β-carotene is widely used in the food industry, feed industry, medicine and cosmetics industry. At present, the methods used to obtain β-carotene include natural extraction, chemical synthesis and microorganisms.
First of all, β-carotene has good coloring properties, the coloring range is yellow, orange-red, strong coloring power, stable and uniform color, and can coexist with K, Zn, Ca and other elements without discoloration, and is especially suitable for compatibility with children's food. It can also be used for the coloring of tablet sugar coating, and its color and stability are better than lemon yellow and carmine double color sugar coating method. Domestic β-carotene has been listed as a colorant in the National Standards of the People's Republic of China (Sanitary Standards for the Use of Food Additives GB-2760-96). β-carotene is used in common foods through synthesis or fermentation.
β-carotene is widely used in health foods as a raw material for nutrition fortifiers.
Like other carotenoids, β-carotene is an antioxidant. Eating foods rich in β-carotene can prevent the body from contacting a damaging molecule called free radicals, which can cause damage to cells through the oxidation process.
At the same time, β-carotene is converted into vitamin A by the body when needed. If the body consumes too much vitamin A, it can cause poisoning. When the human body needs it, β-carotene will be converted into vitamin A. This feature makes β-carotene a safe source of vitamin A.
Moreover, β-carotene is an excellent antioxidant. It has a synergistic effect with vitamin E and vitamin C. Their combination is called the "iron triangle" of antioxidants and has a strong antioxidant effect. Adding β-carotene to lipstick, rouge and other cosmetics can make the color naturally plump, nourish and protect the skin.
