Abstract (en)

The invention relates to a method for the production of mid-fraction by fractional crystallization of fatty substances, in which: i) a fatty substances comprising feedstock is subjected to a topping fractional crystallization treatment providing a stearin topping fraction and an olein topping fraction; ii) the olein topping fraction is subjected to a bottoming fractional crystallization treatment providing the mid-fraction and an olein bottoming fraction; iii)the stearin topping fraction and the olein bottoming fraction are combined and subjected to interesterification, and the interesterified mixture of fatty substances is recycled to the topping fractional crystallization treatment. <IMAGE>
