  • Patent number: 9826766
    Abstract: The use of a polysaccharide in a method for improving the flora of the colon of nursing infants and/or infants, thus treating or preventing colic and enterocolitis and therefore improving and/or generally stimulating the intestinal well-being of nursing infants and/or infants. A food composition for feeding nursing infants and/or infants, including at least one polysaccharide for treating or preventing colic and enterocolitis and improving and/or stimulating the intestinal well-being of nursing infants and/or infants. The polysaccharide used is a branched maltodextrin, preferably with a molecular mass of between 400 and 4500.
    Type: Grant

  • Patent number: 9783619
    Abstract: Hyper-branched maltodextrins having a dextrose equivalent (DE) between at least 8 and at most 15 and a molecular weight or Mw between at least 1,700 and at most 3,000 daltons, characterized in that same have: a 1,6 glucoside bond content between at least 30 and at most 45%; a soluble indigestible fiber content, which is determined according to the AOAC No. 2001-03 method, between at least 75 and at most 100%; and a hypoglycemic capacity expressed according to a test A, which:—in vitro, results in an 80 to 90% reduction of the ?-amylase hydrolysis of standard maltodextrins, and—in situ, by a 30 to 45% reduction in the intestinal digestive activity of standard maltodextrins.

  • Publication number: 20160250127
    Abstract: A composition including at least a polyol for the prevention of oral and dental infections or diseases and/or maintaining good oral and dental hygiene, thus allowing the maintenance of good oral and dental health. More specifically, treating demineralisation of dental enamel, and especially for stimulating remineralisation thereof, using the composition including at least one polyol selected from maltitol and xylitol.

  • 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.
