Vitamin E is a group of fat-soluble compounds, mainly consisting of tocopherols and tocotrienols. It is primarily known for its antioxidant properties, helping to protect cells from oxidative damage caused by free radicals.
Manufacturing Process of Vitamin E
Vitamin E can be sourced naturally or synthetically:
- Natural Vitamin E: It is mainly extracted from plant oils, like wheat germ, sunflower, or safflower oil. The extraction involves separating the oil from the plant material through processes like pressing or solvent extraction. The oil is then refined, purified, and subjected to distillation to obtain Vitamin E (typically in the form of alpha-tocopherol).
- Synthetic Vitamin E: Synthetic forms are produced chemically, where petrochemicals are processed to form tocopherols. This process involves the use of isophytol and trimethylhydroquinone as raw materials. This form is labeled as “dl-alpha-tocopherol.”
Natural forms are often considered more bioavailable than synthetic ones.
