    Abstract: A process with excellent productivity by which noncrystalline cellulose r educed in cellulose I type crystallinity can be efficiently obtained from a cellulose-containing raw material. The process is for producing noncrystalli ne cellulose from a cellulose-containing raw material having a cellulose I c rystallinity calculated with the following formula exceeding 33%, wherein th e cellulose-containing raw material has a bulk density of 100-500 kg/m3 and the residual components obtained by removing water from the raw material hav e a cellulose content of 20 mass% or higher. The process for noncrystalline- cellulose production comprises treating the cellulose-containing raw materia l with a medium type pulverizer to reduce the cellulose I crystallinity to 3 3% or lower. Cellulose I crystallinity (%) = [(I22.6-I18.5)/I22.6] x 100 [I2 2.6 represents the diffraction intensity for the lattice plane (002) in X-ra y diffractometry, and I18.5 represents the diffraction intensity for the amo rphous part.]
