Application of crude invertase preparate in beverage industry..Peer-reviewed article

J. KOVÁČ, R. MIKONY

A crude invertase preparate was used for the enzyme conversion of saccharose. The enzyme preparate was obtained from the biomass of Saccharomyces cerevisiae (baker's yeast) in the process of induced autolysis. Further the enzyme was purified using usual procedures. The rate of inversion in a concentrated grape cider was compared with the rate of acid hydrolysis. The results showed that the invertase preparate is applicable for the saccharose inversion in concentrated ciders in a large range of the saccharose concentrations. A positive effect of the temperature on the enzyme efficiency has been observed. The content of acids affects the rate of acid hydrolysis especially at higher temperatures. For the enzyme hydrolysis their effect can be neglected.
