The subject is focused on training of food technologist on the level to be able to combine scientific knowledge of chemical, biochemical, physical and engineering sciences in the branch of fat technology. It provides a basic overview of physico-chemical properties of triacylglycerols and fatty acids in system solid-liquid state, microstructure formation and its influence on texture of fat products and fat-rich foods. The behavior of liquid-gaseous state system is described by analogy. Applied theoretical basis of chemical and biochemical processes is used for explanation of technologies.
