Abstract

This study aimed to evaluate yields of obtaining fructose syrups from industrial cassava (Manihot esculenta C) at pilot scale since the varieties cultivated in the Colombian Caribbean have shown their benefits in the generation of different products at laboratory scale. However, to take advantage of the deficit in the domestic supply through industrial production, it is necessary to increase the size gradually, generating the least impact on its productivity. The yields of starches were obtained through mass balance. The kinetic evaluation of the processes of liquefaction and saccharification was made by quantifying the reducing sugars by the DNS technique. The production of fructose syrups was evaluated by the method of GOD/POD, using a completely randomized design with three levels of starch concentration (25, 30, 35% w/v, respectively) and five levels of industrial cassava varieties (Orense, Caiselli, Gines, Veronica, Tai). Wet extraction of the starch reported yields between 7.5 and 15.8% w/w. The highest yields in the enzymatic hydrolysis were obtained with the varieties Corpoica-Tai and Corpoica-Caiselli with Dextrose Equivalents (DE) of 94.97 and 93.41% respectively. In the isomerization stage, the best result was for the 30% w/v Corpoica-Tai variety with 104.56 kg of fructose/ton of fresh cassava, values 10% lower than those reported a laboratory level. The process is technically feasible requiring improvements, especially in the wet extraction stage of starch.
