    Processing of wheat bran to sugar solution

  • Original language description

    In accordance to better exploitation of raw material for bioethanol production we try to find the method for saccharification of problematic cover part of grain, so called bran. The bran consists of three main components: residual starch, hemicellulose and cellulose. Whereas hydrolysis of starch is easy and well solved, there are questions how to optimise hydrolysis of all polysaccharides together, including hemicellulose and cellulose. The bran was treated with starch degrading enzymes (Termamyl 120 Land AMG 300 L) in order to remove the starch from the solid particles and use the starch-free residue for hydrolysis of hemicelluloses to pentoses. This starch-free residue (SFR) was treated with sulphuric acid and high temperature during exact time. Different times of pre-treatment (10-50 min), different temperatures (110-180 _C) and different concentrations of sulphuric acid (1-4% of weight of slurry) were tested, as well as presence of furfural and 5-hydroxy-methyl-2-furaldehyd (HMF),

    Zpracování pšeničných otrub na sacharidické roztoky

  • Czech description

    Článek se zabývá komplexním zpracování obilí na bioethanol, konkrétně využitím pšeničných otrub pro produkci jednoduchých cukrů. Pro hydrolýzu polysacharidů (zbytků škrobu, hemicelulosy a celulosy) obsažených ve frakci otrub je využívána jak enzymová, tak kyselá hydrolýza. Byly nalezeny vhodné reakční podmínky s ohledem na rychlost konverze a minimalizaci tvorby inhibičních rozkladných produktů jako je furfural. Z tohoto pohledu optimální bylo použití 1 % kyseliny sírové při 130 °C po dobu 40 minut.
