dc.description.abstractThermogravimetry, TG, of lipids is an appropriate analytical method, commonly used to correlate the kinetic parameters of the thermal degradation of lipids and their composition. Thus, samples of total lipids extracted from the raw fatty tissue of fallow deer were subjected to non-oxidative and oxidative TG analysis. The samples were previously stored for nine months at +4 °C and -18°C. The material stability was investigated in order to establish the most favorable conditions for the production and storage of different foods. The total lipids were extracted according to the Folch method. The identification and quantitative analysis of the methyl esters of the fatty acids of the total lipids were performed by capillary gas chromatography. Based on the non-oxidative and oxidative TG results, the activation energies of the thermal degradation and oxidation of the total lipids extracted from different samples of fatty tissue were determined. The Doyle-Gorbachev method was used for the calculations.en
dc.description.abstractTermogravimetrijska (TG) analiza lipida je pogodna analitička metoda na osnovu čijih podataka se mogu korelisati kinetički parametri procesa termičke degradacije lipida sa njihovim sastavom. S obzirom na ovu vrstu primene, izvedena je neoksidativna i oksidativna TG analiza na uzorcima ukupnih lipida ekstrahovanim iz svežeg masnog tkiva jelena lopatara. Uzorci ukupnih lipida su prethodno čuvani devet meseci na temperaturi +4°C i -18°C. Ovom metodom se utvrđuje stabilnost različitih materijala, što pomaže da se utvrde najpovoljniji uslovi proizvodnje i skladištenja raznih životnih namirnica. Prethodno određen masno-kiselinski sastav ukupnih lipida jelena lopatara (Cervus Dama dama L.) je doprineo tumačenju efekata uočenih pri TG. Ukupni lipidi su ekstrahovani metodom po Folhu (Folch). Identifikacija i kvantitativna analiza metil-estara masnih kiselina ukupnih lipida izvedena je na kapilarnom gasnom hromatografu. Na osnovu rezultata neoksidativne i oksidativne TG analize, primenom metode Dojl-Gorbačova (Doyle-Gorbachev ) određena je energija aktivacije procesa termičke razgradnje i termičke oksidacije ukupnih lipida ekstrahovanih iz različitih uzoraka masnog tkiva.sr
