FIELD: chemistry; sugar production.
SUBSTANCE: invention relates to food industry. The method of preparing an invert syrup involves preparation of a sugar-containing syrup with dry substance content of 50-80%, acidification in sulphuric acid to pH 4.5, addition of a β-fructofuranosidase enzyme and hydrolysis of saccharose in a column with an immobilised preparation of a β-fructofuranosidase enzyme on a fibre weakly basic anionite FIBAN AK-22. Saccharose hydrolysis is carried out at 58-62°C and consumption of the immobilised preparation of 6-7 activity units per gram of saccharose.
EFFECT: invention enables to carry out hydrolysis in continuous mode, recycling the saccharose hydrolysis enzyme, possibility hydrolysis in a wider pH interval, reduction of the amount of enzyme preparation used with maintenance of the degree of inversion and simplification of the hydrolysis process.
