Thermogravimetric analysis of corn oil

The research objective was to define thermogravimetric characteristics of corn oil and to carry out the analysis of the obtained data. Func- tional fatty products can be created by introduction in their composition of vegetable oils rich in nonsaturated fatty acids. Corn oil which is perspec- tive raw materials for creation of functional emul- sion fatty products is chosen as the object of the research. Pilot studies were conducted on the de- vice of synchronous thermal analysis of F3 Jupiter STA 449 model in various gas atmospheres by the method of differential scanning calorimetry (DSC). DSK was based on registration of thermal effects of physical and chemical and structural transfor- mations proceeding in the product at programmed change of influencing temperature. Thermal curves were thermograms (curve heatings) which depend- ed mainly on chemical composition and structure of studied substance were the result of thermal analy- sis. As a result of the research in the range of tem- peratures from -50 to +3 °C the profile of corn oil melting, characteristic only for this product (curve DSK) on which was present some blocked endo- thermic peaks (at -33...
