Zusammenfassung:The invention relates to a process for preparing refined-sugar syrup from agricultural sugar-containing raw materials, which may be used in confectionery, bakery, canning industry. According to the invention, the process consists in purifying by acidification the juice obtained from raw materials, in order to decrease the pH level, then heating up until proteins coagulate, which are removed by filtration or centrifuging, subjecting it to the electrolysis with active electrodes, said electrolysis taking place when dissolving polyvalent ions which provides the coagulation of colloids, ultrafiltering the electrolyzed solution next subjecting it to the electrodialysis with ion-exchange membranes for demineralization and finally purifying it on active carbon. Invenţia se referă la un procedeu de preparare a siropului de zahăr rafinat, din materii prime agricole care conţin zahăr, care poate fi folosit în patiserie, brutărie, industria conservelor. Procedeul conform invenţiei constă în aceea că sucul obţinut din materii prime tăiate se purifică prin acidulare, pentru micşorarea pH-ului, apoi se încălzeşte până la coagularea proteinelor, care se îndepărtează prin filtrare sau centrifugare, se supune electrolizei cu electrozi activi, electroliză care are loc când se dizolvă ioni polivalenţi, asigurându-se coagularea coloizilor, soluţia electrolizată se ultrafiltrează, apoi se supune electrodializei cu membrane schimbătoare de ioni, pentru demineralizare şi, în final, se purifică pe cărbune activ.
