Propolis is a gelatinous substance made from the resin collected by bees from plants and mixed with the secretions of bees' glands. The basic ingredient of propolis is total flavonoids, which are essential nutrients that cannot be synthesized in the human body and can only be taken from the diet.

  A key step in the purification of propolis is molecular distillation, which allows the product obtained from this step to be combined with other products such as monoglycerides for production. The molecular distillation process includes crude honey，pre-treatment, feeding, molecular distillation, heating system, separation of light and heavy components, refining, concentrated product, and collection.

  Molecular distillation of honey propolis  is a type of short-path vacuum distillation, characterized by extremely low vacuum pressure. It’s considered the safest mode of separation and purifies thermally unstable molecules and related compounds with low volatility and elevated boiling point.
