A comparison between Hydrochloric acid and Trifluoroacetic acid in hydrolysis method of exopolysaccharide from Ophiocordyceps sinensis in Monosaccharide composition analysis by GC-FID

The present study investigated comparing HCl and TFA to consider which acid performed better on hydrolyzing EPS. The results of the study might create a premise for further studies on the chemical structure of EPS.
