This Malaysian Standard specifies requirements for different products of palm stearin, i.e. the high-melting fraction obtained from fractionation process of Malaysian palm oil through any of the following three processes:-
a) Dry fractionation through crystallisation of the oil by controlled cooling and subsequent filtration.
b) Detergent fractionation through crystallisation of the oil by controlled cooling and separation of the fractions after addition of a surface active agent; after fractionation, the surface active agent is removed by washing.
c) Solvent fractionation through controlled crystallisation of the oil in a solvent followed by separation of the fractions; after separation, the solvent is removed from each fraction.
