The influence of sulfurous acid concentration, temperature, solid to liquid ratio and time of treatment on the reducing substances yield and concentration during high temperature hydrolysis of birch sawdust was investigated. The highest concentration of reducing substances is achieved by hydrolysis of birch sawdust with 1,77 and 2,0 % wt.
