ABSTRACT

Glucose and fructose production is based in the inversion of sucrose. This work was aimed to obtain both compounds by enzymatic hydrolysis using immobilized invertase. The biocatalyst used was invertase-Chitosan:Chitin-carboxymethylcellulose which retained 50 % of the activity after 170 days of operation. The substitution of the acid inversion in the technological process to produce glucose and syrup by continuous enzymatic inversion was evaluated at the Basic Industrial Unit “Chiquitico Fabregat”, in Villa Clara, Cuba. Parameters of design and operational conditions of the bed reactor were analyzed. The preliminary feasibility evaluation of the industrial enzymatic process showed its technical and economical superiority over the acid inversion system.
