ABSTRACT

The physical properties of palm, palm kernel and coconut oils are reviewed and compared and contrasted with the properties of other oils and fats. More information is available for palm oil than for the other two. The properties of mixtures of the oils also are considered, especially mixtures of palm and palm kernel oils in which a eutectic interaction occurs. Basic physical properties considered are density, specific heat, heat of fusion and viscosity. Where appropriate, data is tabulated in SI and Imperial units. Experimental methods used for determining melting points and solid fat contents are discussed and the empirical nature of the results emphasized. Wiley melting points and Slip melting points, and Solid Fat Content by NMR and Solid Fat Index by dilatometry, are compared and comparative data given. For palm oil, detailed olein and stearin information is presented. The phase behavior and polymorphism of the three oils is reviewed. Special attention is given to the post-hardening phenomenon in palm oil and the effects of diglycerides and storage time on phase behavior. More... »
