  • Patent number: 9200087
    Abstract: The invention relates to branched soluble glucose polymers made of starch having an amylose content of at least 30 wt %, preferably 35 wt % to 80 wt %, having a glycosidic linkage ?-1,6 content of 7% to 10%, preferably 8% to 9%, and a MW of 50,000 to 150,000 daltons, characterized in that the polymers are resistant to pancreatic alpha amylase, expressed according to a test “B” for a reducing sugar content of 25% to 35%, and a MW of released products of 6,000 to 12,000 daltons.
    Type: Grant
    Filed: February 1, 2011
    Date of Patent: December 1, 2015
    Assignee: ROQUETTE FRERES
    Inventors: Laetitia Guerin-Deremaux, Carole Petitjean, Daniel Wils
  • Patent number: 8445460
    Abstract: The invention relates to soluble, highly branched glucose polymers which are obtained by enzymatic treatment of starch, having a reducing sugars content of less than 3.5%, exhibiting a proportion of ?-1,6-glucosidic linkages of between 20% and 30%, a Mw, determined by light scattering, of between 20·103 and 30·103 daltons, and an osmolality of less than 25 mOsm/kg. The invention likewise relates to a method of obtaining these polymers and to their use in the pharmaceutical and food industries, more particularly in the field of enteral and parenteral nutrition, and in the field of peritoneal dialysis.
