The present invention relates to a method for producing beads comprising a material capable of gelation, said method comprising the steps of: (i) combining (a) a liquid composition comprising a material capable of gelation; and (b) a first hydrophobic phase; (ii) subjecting the liquid composition and the first hydrophobic phase, to means for emulsification in a first reactor by addition of external mechanical energy creating an emulsion comprising individual droplets comprising the material capable of gelation in the first hydrophobic phase (wherein the material capable of gelation provides a discontinuous phase and the first hydrophobic phase provides a continuous phase); (iii) stabilising the droplets by transferring the emulsion from the first reactor to a stabilisation reactor wherein the emulsion obtained in step (ii) is subjected to means for gelation in order to obtain gelation within 5 minutes or less, and the beads are formed.

La présente invention concerne un procédé de production de billes qui contiennent un matériau apte à gélifier, ledit procédé comprenant les étapes qui consistent à : (i) combiner (a) une composition liquide qui contient un matériau apte à gélifier et (b) une première phase hydrophobe, (ii) exposer la composition liquide et la première phase hydrophobe à des moyens d'émulsification dans un premier réacteur, par apport d'énergie mécanique extérieure, pour former une émulsion qui comprend des gouttelettes individuelles qui contiennent le matériau apte à gélifier dans la première phase hydrophobe (le matériau apte à gélifier formant une phase discontinue et la première phase hydrophobe formant une phase continue) et (iii) stabiliser les gouttelettes en transférant l'émulsion du premier réacteur à un réacteur de stabilisation dans lequel l'émulsion obtenue à l'étape (ii) est exposée à des moyens de gélification pour obtenir une gélification en 5 minutes ou moins, ce qui forme les billes.
