Similarly to pollen, royal jelly can be used as a dietary supplement because of their nutritious value. They have published many chemical analyzes of royal jelly in recent years. After the latest technological developments, we are able to provide detailed analyzes of the composition of this unusual and complex acid substances (pH 3,6 to 4,2).
The main components of royal jelly are water, proteins, sugars, lipids and mineral salts. The composition of royal jelly is relatively stable when comparing different colonies of bee races and time. Water is about the 1/3 of fresh royal jelly.
Moreover, proteins and sugars are by far the major components. Although small amounts, all amino acids necessary for humans are in the royal jelly. Furthermore a number of important enzymes are present therein. (FAO, 1996)
