The microcrystalline cellulose (MCC) was prepared from oil palm biomass, empty fruit bunch (EFB) for increasing the usability of EFB. The morphological, physical and chemical properties of MCC made from EFB were evaluated by comparing with those of the commercial MCC obtained from AVICEL. The EFB-MC...

인도네시아의 팜오일 생산량은 어떠한가? | 오일팜은 팜오일의 생산을 위해 주로 인도네시아와 말레이시아 등의 열대지방에서 집중적으로 재배되고 있다. 특히 인도네시아의 경우 8.9백만 ha(한국 국토 면적 9.9백만 ha)로 넓은 재배 면적을 가지고 있는데, 팜오일 열매 수확량은 2010년 2억 2천만톤, 2013년 2억 7천만 톤으로 매년 생산량이 꾸준히 증대되고 있으며2), 인도네시아 23.5 백만톤(2011년 기준)3), 말레이시아 11.9 백만톤의 팜오일이 매년 생산되고 있다. 오일팜의 재배와 팜오일 생산을 통해 오일팜 중 빈오일팜 열매송이(EFB, Empty fruit bunch), 오일팜 씨박(PKS, Palm kernel shell), 오일팜 잎(OPF, Oil palm frond), 오일팜트렁크(OPT, Oil palm trunk) 등 다양한 폐기성 바이오매스가 대량으로 발생된다. | |
빈오일팜 열매송이의 특징은 무엇인가? | EFB는 셀룰로오스 44.2%, 헤미셀룰로오스 33.5 %, 리그닌이 20.4 %로로 구성되어 있는데10), EFB 구성성분 중 가장 큰 구성을 차지하는 셀룰로오스는 바이오매스의 주요 성분으로, 최근 고부가가치화를 위한 다양한 연구개발이 집중되고 있는데, 특히 식의약 소재 등의 주요 원료로 활용되는 MCC(Microcrystalline cellulose, 미세결정셀룰로오스)제조에 대한 관심이 증대되고 있다. | |
MCC의 특징은 무엇인가? | 글루코스의 β-D-1,4 글루코시드 결합을 이루고 있는 구조로 구성된 MCC11)는, 순도가 높고 불순물이 거의 없고, 높은 결정화도(약 55 ~ 80%)를 가지며12), 친환경적이고 인체에 무해한 이점을 활용하여 증점제, 수분보유제, 제제 제조 등의 목적으로 화장품, 식품, 제약산업 등에 1960년대 이후 널리 사용되고 있는 주요 소재로써12,13), 주로 목재를 가수분해하여 추출하거나, 면섬유를 무기산 용매로 용해하여 MCC를 제조 및 사용되어지고 있다. |
