The present invention relates to a process for producing protein microparticles in dilute organic acid solutions and in the absence of an alcohol such as ethanol. The microparticles are formed by dissolving a cereal prolamin protein in a concentrated organic acid solution with agitation and then diluting the solution with an aqueous solution. Protein microparticles having vacuoles are thus formed. The protein microparticles may be used to form powders, films, coatings, matrices, scaffolds and the like. Complete films can be formed from the protein microparticles of the invention.
Cette invention concerne un procédé de production de protéines microparticulaires dans des solutions diluées dacide organique et dépourvues dalcool tel que léthanol. Les microparticules sont formées en dissolvant une prolamine dorigine céréalière dans une solution concentrée dacide organique sous agitation, puis en diluant la solution avec une solution aqueuse. Il se forme ainsi des protéines microparticulaires vacuolaires. Ces protéines microparticulaires peuvent être utilisées pour former, notamment, des poudres, des pellicules, des revêtements, des matrices et des échafaudages. Des pellicules complètes peuvent être formées à partir des protéines microparticulaires de linvention.
