  • Patent number: 8680250
    Abstract: The present invention is one that, in a pollen protein extracting method, enables mass production, and while improving production efficiency, achieves a reduction in workload such as a reduction in man-hours, reductions in equipment cost and running cost, and an improvement of a work environment. Specifically, a pollen protein extracting method for extracting water-soluble protein from pollen is characterized by including: mixing the pollen and PBS; adding an aggregating agent including a natural inorganic component to a resultant mixed solution and performing stirring; and after formation of a pollen aggregate, performing filter filtration to perform solid-liquid separation.
