Abstract
Microorganisms can enter the process of sugar production through different ways and can lead to economically significant sugar losses, whereas extraction area and juice purification are the most important process steps. Due to the high temperatures, especially thermophilic bacteria play a role in these production steps as they use sucrose and lead to direct losses of sugar. The acidic metabolites formed by these bacteria reduce the pH-value, resulting in hydrolytic cleavage of sucrose and indirect sugar losses as well. As part of this work, the influence of different technologies in sugar factories of AGRANA on occurring MOs should be examined in order to establish new models for optimizing operating procedures based on the results. Consequently, existing disinfection procedures should be refined on the one hand and on the other hand new methods should be evaluated in order to minimize sugar losses caused by Microorganisms.
