The wide variability of raw materials used in chocolates and related products promotes the appearance of "defects" known as fat bloom. This may be due to crystallization problems during tempering or incompatibility between lipid sources. Lipid microparticles may be an option to induce crystallization of cocoa butter and other fats, always trying to achieve the most stable polymorphic form. In this project will be produced, through Spray cooling technique, lipid microparticles (MP) containing 70% cocoa butter and 30% of fully hydrogenated products, containing trisaturated triacylglycerol or emulsifiers with 52% or 90% monoacylglycerol. The MPs will be applied in spreadable creams and the ability to prevent or delay the appearance of fat bloom will be evaluated. (AU)
