Specialty fats products

The characteristics of specialty fats products are very different from the fat in general such as margarine, shortening, pastry fat, filling / cream fat, and the othes. In general, its application are divided into three groups: (i) the molded products such as chocolate bars and pralines, (ii) coated / enrobed products, ie, chocolate coatings / non-chocolate wafers, biscuits, nuts, fruits and other and (iii) filling or center in the confectionery product.
This characteristic is related to the crystal structure, in which brown fat has a structure of β (beta) with the crystal density arrangement and melting point is high, the speed of crystal growth is relatively slow, but has a very stable crystalline construction. On the other hand, other types generally have a form of β'(beta-prime) that has the opposite properties. The distinction of its structure is very difficult to distinguish from its melting point, and the parameters that can describe the typical characteristics of brown fat is solid fat content (SFC). SFC profile of specialty fats should be sharp and steep, where at temperatures less than 25 degree C they should have SFC more than 68% to ensure the hard and brittle texture, as well as at temperature of 35 degree C should have SFC less than 5% to ensure no waxy taste in the mouth when chocolate consumed.
They are sometimes called by confectionery fat, hard butter, or cocoa butter alternatives (CBA). In general, specialty fats are divided into 3 groups, namely: Cocoa Butter Equivalent (CBE), CB Replacer (CBR), CB Substitute (CBS).
