Subject of research physicochemical parameters of vegetable fats, parameters of phase transformations and mass fractions of solid triacylglycerols by the method of differential scanning calorimetry; fatty acid and triacylglycerol composition of vegetable fats. The aim of the work is to study the parameters of phase transitions of some vegetable fats by the method of differential scanning calorimetry in correlation with fatty acid and triacylglycerol composition. Research methods physico-chemical parameters of experimental vegetable fats, which characterize the processes of melting and crystallization, determined by standard methods; phase transition parameters and mass fractions of solid triacylglycerols were investigated by the method of differential scanning calorimetry; fatty acid and triacylglycerol composition of vegetable fats was determined using chromatographic analysis; processing of research results was performed using software packages Microsoft Excel, MathCad and Statistica. Theoretical and practical results: various parameters of processing of vegetable fats by a method of differential scanning calorimetry are investigated; rational conditions of research of various samples of vegetable fats are established; the correlation between fatty acid and triacylglycerol composition of experimental samples of vegetable fats and characteristics of phase transitions by the method of differential scanning calorimetry was established; the influence of vegetable fat composition on mass fractions of solid triacylglycerols at different temperatures by the method of differential scanning calorimetry was investigated. Efficacy of application: recommendations for the application of the DSC method in the oil and fat industry have been developed. Scope - oil industry.   Product Description popup.authors Demidova Anastasia O Mazaieva Viktoriia S Petik Igor P Sytnik Natalia S Fedyakina Zoya P popup.nrat_date 2021-01-02 Close
