Composition of hydrolysates of some hardwoods occurring in the process of their hydrothermal treatment by cooking

Solar, Rastislav (author), Tišler, Vesna (author), Kačik, František (author)

Oak wood samples were hydrothermally treated at 80 and 120° C. The times of treatment varied from 2 to 32 hours according to the temperature. Obtained hydrolysates were analysed for the contents of acetic acid, 2-furaldehyde and monosaccharides prior to and after the inversion. Also the specific gravity, pH, contents of reducing substances and the weights of dry residua were determined.

Abstract

Vzorce hrastovega lesa smo hidrotermično obdelali pri 80 °C in 120 °C, časi obdelave so se glede na temperaturo spreminjali od 2-32 ur. Dobljeni hidrolizati so vsebovali ocetno kislino, 2-furaldehid in monosaharide pred in po inverzijiI. Hidrolizatom smo določili njihovo gostoto, pH, količino reducirajočih substanc in vsebnosti suhe snovi.
