Constituent Sugar Analysis of Cellulose Nanofibers

User Benefits

- This method enables simultaneous analysis of the main constituent sugars of cellulose nanofiber (CNF). - High sensitivity and selectivity analysis of saccharides is possible by using the post-column fluorescence derivatization method.

Introduction

Cellulose nanofiber (hereinafter, CNF) is a technology which effectively utilizes biomass with high efficiency, and thus is one approach toward building a sustainable recycling society system. Plant cell walls consist of fibers called cellulose microfibrils, in which cellulose molecule chains are bound together in a regular structure. The substance obtained by physically or chemically defibrillating cellulose microfibrils is called CNF. In recent years, bacterial cellulose nanofibers (BCNF) has also been produced by using bacteria to synthesize cellulose from biomass-derived glucose. Because the saccharides that make up the complete CNF differ depending on the type of biomass used as the material of the CNF, it is necessary to determine the type and ratio of the saccharides when commercializing a CNF product. Here, various types of CNF were hydrolyzed, and the types and ratios of their constituent sugars were determined with a Nexera reducing sugar analysis system
