Abstract
This article reviews recent studies of crystallization behavior of polymorphic modifications of principal saturated and mono-cis-un-saturated fatty acids, and of mixed-acid triacylglycerols; stearic acid, oleic acid, erucic acid and SOS (symmetric l,3-di-stearoyl-2-oleoyl glycerol). Thermodynamic and kinetic aspects of the polymorphic crystallization are discussed in relation to molecular structures and thermal properties, which have newly been elucidated with X-ray diffractometry and vibrational spectroscopy.
