A method for producing porous cellulose particles having a uniform particle size, high strength, and a pore size of 1 μm or less is provided. The method for producing cellulose particles includes a step of granulating a cellulose hydrolyzate and / or a cellulose alkaline lysate, a step of freezing the obtained cellulose particles, and a drying for naturally drying the frozen cellulose particles. Or a step of granulating the cellulose hydrolyzate and / or cellulose alkali lysate, and a drying step of naturally drying the obtained cellulose particles without freezing. [Selection] Figure 2 |
