摘要：

The objective of this paper is to present an integration of three chromatographic methods for the monitoring of saccharides and degradation products in partially hydrolyzed starch. In our method, a single sample preparation is analyzed by two aqueous high-performance liquid chromatography columns and one aqueous size-exclusion chromatography column. In less than 1 h, the quantification of mono- and oligosaccharides as well as the determination of the polysaccharides profile of these hydrolysates is obtained. Simultaneously, the degradation products, mainly levoglucosan and (hydroxymethyl)furfural, are also quantified. This methodology may therefore be applicable for the control of acid or enzymatic processes.
