Heat-stable, aqueous lactoferrin composition and its preparation and use

摘要

The invention pertains to an aqueous composition containing lactoferrin, 35-70 wt % carbohydrate and/or polyol stabilizers, based on the total weight of the aqueous composition, said composition exhibiting a pH higher than 2, lower than 5. At these 5 conditions, the aqueous composition and lactoferrin contained therein may be subjected to a heat treatment without significantly affecting the physiological activity of the lactoferrin. The invention thus particularly pertains to the above aqueous composition, being heat-treated, thus containing heat-stabilized lactoferrin.
