This Malaysian Standard prescribes the requirements for different products of palm kernel stearin, i.e. the higher-melting fraction obtained from the fractionation of Malaysian palm kernel 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 separation, 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 by distillation.
