Patents by Inventor Jean-Michel Roturier

Jean-Michel Roturier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10479812
    Abstract: The present invention relates to maltooligosaccharides, the content of ?-1,4-glycosidic bonds of which is between 70% and 80% of the total number of 1,4-type glycosidic bonds. The invention also relates to the method for manufacturing these maltooligosaccharides. Said maltooligosaccharides afford all the benefits of fiber-based foods, with an extremely low nutritional value. Such a compromise is particularly advantageous for use in healthy balanced diets, but also in the treatment and/or prevention of the pathology of diabetes. The invention also relates to the use of said maltooligosaccharides in the fields of human food and animal feed.

  • Patent number: 9534078
    Abstract: A method for measuring the thermal stability of succinic acid includes the following steps: 1) preparing a succinic acid crystal powder having less than 1% residual water content; 2) placing 10 g of the crystal powder in an oven at 220° C. for 2 hours; 3) pulverizing and sieving the crystal powder processed in this way, such that the particle size distribution thereof is between 0 and 10%, and preferably between 4 and 6% for particles larger than 500 ?m in size, between 20 and 40%, and preferably between 25 and 35% for particles between 200 and 500 ?m in size, between 50 and 75% and preferably between 55 and 70% for particles smaller than 200 ?m in size; and 4) measuring the color, in a spectrocolorimeter, of the pulverized and sieved powder and determining the average value of the yellow (index “b”).

  • Patent number: 7612198
    Abstract: The invention relates to soluble highly branched glucose polymers, having a reducing sugar content of less than 1%, a level of ?-1,6 glucoside bonds of between 13 and 17% and an Mw having a value of between 0.9×105 and 1.5×105 daltons, characterized in that their branched chain length distribution profile consists of 70 to 85% of DP of less than 15, of 10 to 16% of DP of between 15 and 25 and of 8 to 13% of DP greater than 25.

  • Patent number: 6428992
    Abstract: The present invention relates to a process for the purification of 1,3-propanediol from a fermentation medium of a 1,3-propanediol-producing microorganism, comprising 1,3-propanediol and fermentation coproducts consisting at least of glycerol, wherein the 1,3-propanediol-producing microorganism is separated from the other components of the fermentation medium to give a clarified aqueous solution, clarified aqueous solution is passed over a cation exchange resin to give at least one fraction comprising purified 1,3-propanediol and at least one fraction comprising the fermentation coproducts, and the 1,3-propanediol is recovered.
