SummaryInteresterification of milk fats resulted in increased softening points, hardness and high melting glycerides (HMG). Increasing the content of trans-unsaturated acyl groups in milk fat resulted in increased softening points and hardness. While the increased solid fat content after interesterification occurred mostly at the higher measuring temperatures, the increase due to isomerization occurred mainly at the lower measuring temperatures. However, in both cases hardness was increased at all measuring temperatures. These results indicate that glyceride structure and trans-unsaturated acyl content influence the physical properties of the solidified fat.

Cooling Procedure

SummaryThe crystal habit of milk fat is determined by the cooling procedure employed and is changed markedly by interesterification (randomization) of the fat. X-ray diffraction analysis indicated that slowly cooled milk fat occurs in both beta prime and beta modifications, whereas in rapidly cooled milk fat, evidence for the beta prime modification only was obtained. The long spacing was greatly increased by interesterification, especially when the fat was slowly cooled. The presence or absence of certain high melting glyceride fractions greatly influenced solid fat content, softening point and hardness of milk fat.

The Amazon region has richness of oleaginous plants that have attracted attention due to its unique properties. Integrating local communities in an economic chain of valorization of fats/oils can enhance the social dimension of local oleaginous industry sustainability. Given the large diversity of raw materials and the possibility to mix them in different proportions, an experimental effort must be done to evaluate the physical properties of such feedstocks. In this context, the development of computational tools able to estimate physical properties based on rigorous thermodynamic models can orient the experimental efforts thorough the mixtures of fats and oils most promising. The evaluation of the melting curves of nine Amazonian oils and fats is done by using thermodynamic modeling of the solid-liquid equilibrium and optimization tools. The binary blends of different raw materials were also evaluated. An average absolute error of 4.5 °C was observed for the melting point and an absolute error of 3.8% was observed for the Solid Fat Content predictions over different temperatures and blends composition.

Cocoa butter is the most essensial component in chocolate formulation and represent the biggest characteristic of this product. Indonesia is the third cocoa producers with cocoa producing area spread out in different geographic region and may affect in cocoa butter profiles. The aim of this experiment was to evaluate the fatty acid characteristic and physical properties of cocoa butter from smallholder estate relate to geographic region and climate. This experiment was conducted using unfermented cocoa bean from smallholder estate in eight provinces of Indonesian most growing areas. Fatty acid composition evaluated through the different region and physical properties evaluated in melting profiles and solid fat content. The result explain the fatty acid characteristic of Indonesian cocoa butter consist of palmitic acid (C16:0) 26.28–29.20%, stearic acid (C18:0) 32,14–37.29% and oleic acid (C18:1) 32,14–37,29%. Growing temperature signifi- cantly affects the increase of palmitic acid composition contribute to cocoa butter hardness. Cocoa butter completely melt in temperature of 36.65–39.20OC and solid fat content ranged 7.288–16.82% in 33OC and ranged 0.02–0.29% in 38OC. This Indonesian cocoa butter comply to the classification of hard cocoa butter.
