Biomolecular Physical Chemistry


The physical properties of food lipids such as polymorphism, crystal structure, structure of self assembly systems, structural variations during kinetic process, melting point, enthalpy of fusion, etc., have been studied because these affect the texture of foods such as chocolate, margarine, cream and so on.

1) Elucidation of the kinetic process of phase transition and polymorphic transformation of lipids(Ueno, S.)
