Abstract
La présente invention concerne un concentré protéique de lactosérum (<i>whey protein concentrate</i> / WPC) à faible teneur en graisse et son procédé de production. Le procédé de l'invention fait intervenir les étapes suivantes: concentration de la partie solide du lactosérum pour produire un WPC intermédiaire; dilution du WPC intermédiaire dans de l'eau pour obtenir une force ionique inférieure ou égale à une force ionique présélectionnée; réglage du pH du WPC intermédiaire dilué pour qu'il soit compris entre 3,8 et 5,0; maintien du pH à cette valeur pour une durée permettant d'optimiser la formation de floculat; et élimination du floculat pour que ne subsiste qu'un surnageant de WPC à faible teneur en graisse. Le WPC ainsi obtenu a une teneur en graisse <= 4 % et de préférence <= 1 %. Le procédé trouve des applications en particulier pour la production de WPC à faible teneur en graisse à partir de lactosérum doux présentant des propriétés fonctionnelles similaires à celles d'un WPC classique dérivé du lactosérum acide. De plus, le procédé peut être utilisé pour la production de WPC à faible teneur en graisse à partir de lactosérum acide ou doux ayant des propriétés fonctionnelles et une composition similaires à celles d'un isolat protéique de lactosérum (<i>whey protein isolate</i> / WPI).
