Purification of glucomannan from salep: Part 2. Structural characterization

The aim of this study was to investigate the effects of different extraction temperatures (25, 55 and 85 °C) on the structural characteristics of glucomannan (GM) purified from salep. All extraction conditions reduced protein content and molecular weight of salep. The effectiveness of removing the impurities and the highest purity of GM25 were observed with size exclusion profile. FTIR experiments demonstrated the presence of acetyl group,...
