Abstract

The role of fats in food technology is mainly to develop the desired consistency. The simplest way to reach this goal is the blending of different fats. The aim of our work was to study the solidification and melting properties of blends of coconut oil and anhydrous milk fat. Pure fats and their 25–75%, 50–50%, and 75–25% blends were investigated. Melting profile and isotherm crystallization were measured by pNMR. Non-isotherm melting and solidification were detected by differential scanning calorimetry (DSC). Possible applications of the blends were established. Results show that AMF and coconut oil has limited miscibility, which is dependent on the temperature. Below 22 °C AMF is the softening component, above 22 °C the effect is inverse. Coconut oil accelerates solidification of AMF, however, basic crystal forms of AMF remained.
