Vitamins are widely found in nature, and some of them are synthesized from chemicals. Due to its safety problems, with the rise of green chemistry and improvements in the process using molecular distillation technology , the production of natural vitamin E has skyrocketed.
The extraction of natural vitamins has a wide range of applications, such as the extraction of high-purity carotenoids from palm oil esterification using molecular distillation equipment, and the optimization of the extraction of paprika red pigment using molecular distillation.
The steps of vitamin purification are divided into distillate from vegetable oil, raw materials,pre-treatment, feeding, distillate deodorization, methanol esterification, cooling, molecular distillation, separation and purification, vitamin concentrate, and collection.
