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.
