In this study, nanofibrillated cellulose was extracted from soybean hulls - a by-product of soybeans - and compared with soybean hull nanofibrillated cellulose obtained by using other nanofibrillated methods. Dry soybean hulls were ground into prepare micrometer-sized powders, from which microcellulose was isolated using NaOH and HCl. The nanometer-sized cellulose was successfully extracted through ultrasonic dispersion and ball milling. The soybean hull nanofibrillated cellulose exhibited a diameter of 60-100 nm and a length of 0.3-1.0 ㎛, which matches the diameter of soybean nanofibrillated cellulose made by other nanofibrillated methods but is significantly shorter in length.
