This invention relates to a process for continuously fractionating plant, animal or human proteins by selective precipitation of the proteins resulting from placing a solution of proteins in contact with a precipitating agent constituted by a fatty acid of 6 to 14 carbon atoms, such as caprylic acid

This invention relates to a process for continuously fractionating plant, animal or human proteins by selective precipitation of the proteins resulting from placing a solution of proteins in contact with a precipitating agent constituted by a fatty acid of 6 to 14 carbon atoms, such as caprylic acid, is characterized in that respective deliveries of fatty acid and of the protein solution are continuously placed in contact in a mixing chamber of small volume with respect to the deliveries, creating a strong stirring in this mixing chamber; the individual deliveries of fatty acid and of protein solution are adjusted to controlled pH and temperature so as to maintain their ratio equal to a predetermined value; the mixture is then allowed to evolve during a phase of maturation so as to form a suspension; this suspension is separated into a liquid part from which are extracted the proteins having remained soluble, and a solid part containing proteins of different nature; and the parameters intervening in the process, such as delivery, pressure, temperature, pH, resistivity, are permanently monitored. The invention also relates to an installation for carrying out said process.

A process for continuously fractionating plant, animal and human proteins by selective precipitation of the proteins resulting from placing a solution of proteins in contact with a precipitating agent consisting essentially of a fatty acid of 6 to 9 carbon atoms, said process consisting essentially of the following steps of: continuously placing respective deliveries of a fatty acid of 6 to 9 carbon atoms and of the protein solution in contact in a mixing chamber, mixing the fatty acid and protein solution within hundredths of a second to create a strong stirring in the mixing chamber; adjusting the individual rate of delivery of fatty acid and of protein solution to control pH and temperature so as to maintain their ratio equal to a predetermined value; then allowing the mixture to evolve during a phase of maturation so as to form a suspension; separating this suspension into a liquid part from which are extracted the proteins having remained soluble, and a solid part containing other proteins; and permanently monitoring at least one of the parameters intervening in the process, selected from the group consisting of delivery rate, pressure, temperature, and pH.
