| description | The present invention relates to a method for preparing a cellulose rich fibre fraction, said method comprising the steps of: (i) providing straw, (ii) subjecting the straw to a dry mechanical treatment, (iii) subjecting the material obtained in (ii) to a sieving treatment and obtaining at least two fractions, the first fraction passing through the sieve mesh and the second fraction being retained by the sieve mesh, (iv) suspending the second fraction in an aqueous solution comprising one or more enzymes, adjusting pH of the mixture in the range of 4-6.5 and adjusting temperature of the mixture in the range of 30-70°C, (v) subjecting the mixture obtained in step (iv) to a continuous or intermittent mechanical defibration under agitation, (vi) separating the material obtained in step (v) into a cellulose rich fibre fraction and a liquid fraction comprising suspended and/or dissolved lignin, hemicellulose and oligosaccharides, (vii) subjecting the liquid fraction obtained in (vi) to lignin precipitation and obtaining a precipitated lignin rich fraction and a hemicellulose and oligosaccharide rich fraction, and (viii) separating the precipitated lignin rich fraction obtained in step (vii) from the hemicellulose and oligosaccharide rich fraction. |
