FIELD: food industry.
SUBSTANCE: method for obtaining highly-concentrated glucose solutions from cellulose-containing raw materials includes pre-treatment of the raw materials and the subsequent enzymatic hydrolysis. The pre-treatment of the raw materials is carried out by the treatment with a diluted solution of sodium hydroxide with the concentration of 0.5-6.0%, then heating is performed and holding for 1-6 hours is carried out. Enzymatic hydrolysis is carried out at initial substrate concentrations of 250-300 g/l with the introduction of a fresh portion of the substrate every 2-8 hours and the removal of glucose by means of membrane filtration. Miscanthus, or fruit shells, or straw of grain crops are preferably used as a cellulose-containing raw material.
EFFECT: invention allows to utilise cellulose-containing waste and to obtain highly-concentrated glucose hydrolysates.
