Royal jelly is a milky-white secretion produced by bees with plenty of nutrients, however, royal jelly is difficult to preserve at room temperature. With the help of Innova's pilot freeze dryer, the problem was solved.

After the vacuum freeze-drying of the freeze dryer, the internal moisture is sublimated from liquid to gas, and the fresh royal jelly becomes royal jelly powder. Since freeze-drying technology is a physical reaction, it can perfectly preserve the nutrients in food.
