  • Nutritional composition which contain non-digestible polysaccharides and use thereof to reduce transport through tight junctions
    Patent number: 6730661
    Abstract: The present invention relates to the use of one or more non-digestible polysaccharides selected from the group consisting of dextrans having a molecular weight of 8 kD to 40,000 kD, hydrolysed (gluco)mannans having a molecular weight of 0.5 kD to 1,000 kD and hydrolysed (galacto) mannans having a molecular weigth of 0.5 kD to 1,000 kD for the preparation of a nutritional composition to reduce the uptake of high molecular weight substances, allergens and microorganisms through the intestinal wall, more particularly to reduce transport of high molecular weight substances, allergens and microorganisms through the tight junctions in the intestines, the rise in the viscosity of the nutritional composition caused by the polysaccharides being less than 20 mPa.s.
    Type: Grant
    Filed: July 16, 2002
    Date of Patent: May 4, 2004
    Assignee: N. V. Nutricia

  • Nutritional compositions which contain slightly negatively charged, non-digestible polysaccharides and use thereof for reducing transport through tight junctions
    Patent number: 6686341
    Abstract: A nutritional composition which contains slightly negatively charged non-digestible polysaccharides having a molecular weight of 8 kD to 40,000 kD, characterized in that the rise in the viscosity of the composition caused by the polysaccharides is less than 20 mpa·s. This nutritional composition is used to reduce the uptake of high molecular weight substances, allergens and microorganisms through the intestinal wall, more particularly to reduce transport of high molecular weight substances, allergens and microorganisms through the intestinal wall, ore particularly to reduce transport of high molecular weight substances, allergens and microorganisms through the tight junctions in the intestines.
