Abstract

The possibility of using ion-exchange techniques for purifying latex enzymes and extracting the excess of mineral compounds has been studied using papaya latex as an example. Mixed bed ion-exchange has been used in an apparatus with KU-2 cation exchanger in the H+-form and EDE-10P anion exchanger in the OH—form. Optimum processing parameters (component ratio, particle size, mixing rate, etc.) have been chosen. This allowed the ash content to be reduced to the necessary level. The purified latex enzyme solutions will be used in the technology of Karipazim preparation.
