Abstract
Water-soluble or water-dispersible extrudates are provided which are formed of a matrix and vitamin A palmitate. The matrix comprises or consists of octenyl succinate starch and dextrin. Such water-soluble or water-dispersible extrudates have an excellent storage stability and may comprise further components such as other fat-soluble vitamins.
Claims22
An extrudate comprising a mixture adiabatically extruded at a substantially constant temperature of 60° C. to 95° C. of a matrix and at least one fat-soluble vitamin which comprises vitamin A palmitate embedded in the matrix, wherein the matrix consists essentially of octenyl succinate starch and dextrin.
A method of manufacturing an extrudate comprising at least one fat-soluble vitamin which comprises vitamin A palmitate, wherein the method comprises the steps of:
- (i) feeding a matrix mixture of octenyl succinate starch and dextrin into a first barrel of an extruder;
- (ii) injecting water into a second barrel of the extruder which is located downstream of the first barrel of the extruder;
- (iii) injecting the at least one fat-soluble vitamin which comprises vitamin A palmitate into a third barrel of the extruder which is located downstream of the first and second barrels of the extruder;
- (iv) operating the extruder so as to form an aqueous extrusion mixture comprised of a matrix of the octenyl succinate starch and dextrin in which the at least one fat-soluble vitamin which comprises vitamin A palmitate is embedded;
- and
- (v) extruding the aqueous extrusion mixture under adiabatic conditions at a substantially constant temperature from 60° C. to 95° C. through a die of the extruder to provide an extrudate of the extrusion mixture.
