The freeze-dried royal jelly powder is preparedfrom the following raw materials in parts by weight: 60-70 parts of royal jelly, 6-10 parts of maltodextrin, 1-5 parts of beta-cyclodextrin, and 2-8 parts of inositol hexaphosphate. The preparation method of the freeze-dried royal jelly powder comprises the steps of preparing blended solution, carrying out filtrating, and carrying out vacuum freeze-drying. The freeze-dried royal jelly powder and the preparation thereof have the following advantages and effects: the maltodextrin and the beta-cyclodextrin are capable of effectively reducing moisture absorption of the freeze-dried royal jelly powder; the inositol hexaphosphate can cooperate with water-soluble proteins in the royal jelly so as to have the water-soluble proteins effectively protected during the freeze-drying process, so that, decomposition of the water-soluble proteins is reduced so as to achieve the effect of protecting functional components of the royal jelly during the preparation processes; and phosphated distarch phosphate is capable of slowing down decompose rate of amino acids so as to have storage life prolonged. Thus, the effects of small functional component loss, excellent nourishing and health-caring functions, high medical effectiveness and long storage life are achieved.
