Fecha de publicación: 25/12/2013 Fuente: WIPO "royal jelly" The invention relates to a material including royal jelly-decomposing enzyme, a royal jelly-decomposing enzyme, a royal jelly-decomposing material and a decomposing method of royal jelly. This material containing royal jelly-decomposing enzyme is prepared by a method including the following processes from the 2-3 day old queen bee larvae of Apis mellifera: (a) a process of centrifugal treatment of the suspension of body tissues of the queen bee larvae at <=6[deg.]C so as to separate to an upper layer of white solid form, a middle layer of solution and a lower layer of precipitate; and (b) a process of recovering the middle layer as the material containing royal jelly-decomposing enzyme. The royal jerry-decomposing enzyme is characterized by being contained in the above material containing royal jerry-decomposing enzyme. The royal jelly-decomposed products are prepared by using the material containing royal jelly-decomposing enzyme or the royal jelly-decomposing enzyme. The method for decomposing the royal jelly is characterized by using the material containing royal jelly-decomposing enzyme or the royal jelly-decomposing enzyme.
