Abstract

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 μm, which matches the diameter of soybean nanofibrillated cellulose made by other nanofibrillated methods but is significantly shorter in length.


본 연구는 대두 부산물인 대두피로부터 나노 섬유화 셀룰로오스를 추출하고, 다른 나노 섬유화 기법으로 제작된 대두피 나노 섬유화 셀룰로오스와 비교 평가를 수행하였다. 건조 대두피를 분쇄하여 마이크로미터 크기의 분말을 제조한 후, NaOH와 HCl을 이용하여 대두피로부터 마이크로 셀룰로오스를 분리하였다. 초음파 분산 및 볼 밀링을 통하여 나노미터 크기의 셀룰로오스를 추출하는데 성공하였다. 대두피 나노 섬유화 셀룰로오스는 직경 60-100 nm, 길이 0.3-1.0 μm의 크기를 가져 다른 나노 섬유화 기법으로 대두 나노 셀룰로오스와 직경은 유사한 수준이나 길이는 1/5 수준임을 확인하였다.


Keywords: 대두피(Soybean hulls), 마이크로 셀룰로오스(Microcellulose), 나노 섬유화 셀룰로오스(Nanofibrillated cellulose), 볼 밀링(Ball milling)
