Disclosed herein is a process for producing a lactoferrin powder. The process comprises extracting lactoferrin from a native lactoferrin-containing substance and concentrating the extracted lactoferrin to produce a liquid concentrate in which the extracted lactoferrin has an improved stability. The liquid concentrate is then pasteurised by heating to a temperature and for a time effective to do so, after which the pasteurized liquid concentrate is dried under non-denaturing conditions to produce a lactoferrin powder in which substantially all of the lactoferrin is native lactoferrin. L'invention concerne un procédé de production d'une poudre de lactoferrine. Le procédé comprend l'extraction de lactoferrine à partir d'une substance contenant de la lactoferrine native et la concentration de la lactoferrine extraite pour produire un concentré liquide dans lequel la lactoferrine extraite a une stabilité améliorée. Le concentré liquide est ensuite pasteurisé par chauffage à une température et pendant une durée efficaces pour ce faire, après quoi le concentré liquide pasteurisé est séché dans des conditions non dénaturantes pour produire une poudre de lactoferrine dans laquelle sensiblement la totalité de la lactoferrine est la lactoferrine native.
