| Popis: | Ozonization of theobroma oil at different applied ozone dosages was carried out with measurement of peroxide index values, oxygen percentage content and fatty acids composition. The comparison of peroxide values with percentage content of oxygen at different applied ozone dosages showed good correlation (r=0.9923). Unsaturated fatty acids and triacylglycerols decrease with ozone applied dosage due to ozone reaction with double bonds. Small amounts of oleic acid were consumed with applied ozone dosage at 35 mg/g, which demonstrated that peroxide values and oxygen content were not principally increased by the ozone attack on the double bonds, but other mechanisms could be involved in the reaction system. |
