BIOCATALYST FOR PREPARING INVERT SUGAR AND METHOD FOR PREPARING INVERT SUGAR Russian patent published in 2004 - IPC

FIELD: food industry, biochemistry, enzymes. SUBSTANCE: invention relates to biocatalysts and can be used for producing invert sugar. Biocatalyst for preparing invert sugar by sucrose inversion comprises invertase and carbon-containing solid carrier on surface of that a layer of catalytic fibrous carbon is synthesized wherein carbon content is 0.1 wt.-%, not less. Biocatalyst is prepared by invertase adsorption on surface of carbon-containing solid carrier. Process of sucrose inversion is carried out at 20-50 C in flow-type regimen using biocatalyst immobile layer wherein 25% sugar syrup is pumped over through biocatalyst layer. Invention provides preparing biocatalyst with invertase activity and high stability being method for it preparing and the process of sucrose inversion is simple and economical. EFFECT: improved preparing method. 11 cl, 1 dwg, 7 ex
