A separation process for isolation and purification of useful nutrients from food process streams is described. The process includes the steps of contacting an aqueous solution including a nutrient and divalent ions with an ion exchange resin including monovalent ions. The eluate which is depleted of divalent ions is collected and subjected to a process capable of separating monovalent ions to obtain a permeate fraction including monovalent ions and a retentate fraction including said nutrient. The retentate is separated into fractions, wherein at least one of said fractions includes the major portion of said nutrient, which may then be further purified. The ion-exchange resin can be regenerated by contacting the ion-exchange resin with a solution including the permeate fraction until a major portion of divalent ions in the ion exchange resin have been replaced by monovalent ions.
L'invention porte sur un procédé de séparation destiné à isoler et à purifier des éléments nutritifs utiles à partir de courants de transformation des aliments. Ce procédé consiste à mettre en contact une solution aqueuse comprenant un élément nutritif et des ions divalents avec une résine échangeuse d'ions comprenant des ions monovalents. L'éluat qui est appauvri en ions divalents est récupéré et soumis à un processus permettant de séparer des ions monovalents de façon à obtenir une fraction de perméat comprenant des ions monovalents et une fraction de retentat comprenant l'aliment nutritif. Le retentat est séparé en fractions, au moins une de ces fractions comprenant la partie principale de l'élément nutritif qui peut encore être purifiée. La résine échangeuse d'ions peut être régénérée lors de sa mise en contact avec une solution comprenant la fraction de perméat jusqu'à ce que la partie principale des ions divalents soit remplacée par des ions monovalents.
