The consumption of chocolates in the world remains high and the possibility of lack of cocoa butter (CB) is real. The Brazilian law for chocolate allows the use of other fat sources, unless the minimal cocoa solids percentage is maintained. In this regard, several alternative fats are available in the market, specially the fats known as cocoa butter equivalents (CBE), products with full compatibility with the CB. Several existing CBEs in the market are formed of imported raw materials and in this sense this project aims to use Brazilian palm oil stearins, obtained from palm oil fractionation as the main raw materials for the preparation of CBEs using the enzymatic interesterification (EI) as a modification process. The EI is a high selectivity reaction, which increases the possibility of producing high levels of symmetric SUS (saturated-unsaturated-saturated) type triglycerides, the main components of cocoa butter. Fractions will be evaluate through the use of instrumental techniques such as nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC) and polarized light microscopy (MLP).
