Abstract

Procédé de micro-encapsulation. Selon l'invention on forme une émulsion d'une solution aqueuse d'une protéine hydrophile ayant des groupes amino libres dans un liquide qui est sensiblement non polaire ou qui a une polarité inférieure à celle d'un mélange 4 : 1 en poids de cyclohexane et de chloroforme comme phase continue et on ajoute une solution d'un composé capable de polymérisation avec la protéine dans la solution aqueuse de manière qu'une réaction de polymérisation interfaciale se produise. Micro-encapsulation de diverses matières protéiques.
