  • Bee bread containing astaxanthin and hydrophilic colloid and preparation method thereof
    Patent number: 11666070
    Abstract: A bee bread containing a base material of the bee bread, the hydrophilic colloid, ethanol and water, and is prepared according to a certain preparation method. The bee bread containing the astaxanthin and the hydrophilic colloid has the advantages of long preservation time and small nutrient loss. The bee which are fed with the bee bread for a long time can effectively increase the yield of royal jelly and the number of larvae, and extend the life.
