  • Patent number: 5759581
    Abstract: A food grade texture agent in the form of thermally stabilized swelling resistant and non crystalline particles of high amylose starch, which present a gelled soft structure, in which the amylose content of the starch is between 40 and 70%, and in which 90% of the particles have a diameter in the range of 5 to 30 microns. This agent can be prepared by suspending the high amylose starch in water, heating the slurry thus obtained to about 80.degree.-100.degree. C., preferably 90.degree.-100.degree. C., under continuous controlled stirring without shearing but sufficient to avoid particle aggregation and so as to form the desired particle gel product, and then cooling the product. It can be used in food preparations as a fat substitute and/or a whitening agent.

  • Patent number: 5198352
    Abstract: Antibacterially active compositions are prepared from a proteolytic enzymatic digestate of glycopeptides obtained from a protein isolate enriched with soya glycoprotein 7S or with bean glycoprotein II. The glycopeptide digestate is treated with endo-.beta.-N-acetylglucosaminidase H to obtain oligosaccharide compositions which then also may be treated with exo-.alpha.-mannosidase to obtain further oligosaccharide compositions.

    Inventors: Jean-Richard Neeser, Pierre Wursch
  • Patent number: 5100475
    Abstract: The invention relates to a process for the production of a starch dispersible in boiling water by heat treatment in the presence of water and an emulsifier. A mixture of starch, an emulsifier containing at least one fatty acid monoester in a quantity of from 1 to 5% by weight of fatty acid monoester, based on the dry weight of the starch, and water is prepared in such a way that the water content of the mixture amounts to between 20 and 30% by weight, and the mixture is heat-treated for 1 to 20 mins at a temperature of 90.degree. to 120.degree. C. to obtain a starch showing 95 to 100% dispersibility in boiling water.

  • Patent number: 5043160
    Abstract: Diarrhoea is treated by administering particulated carob pod to a patient having diarrhoea wherein the particulated carob pod contains at least 20% by weight, based upon dry matter, of water-insoluble tannins expressed as total polyphenols and wherein the ratio by weight of water-soluble tannins to water-insoluble tannins is below 0.37 as determined in water at 37.degree. C.
    Type: Grant
    Filed: February 25, 1991
    Date of Patent: August 27, 1991
    Assignee: Nestec S. A.
    Inventor: Pierre Wursch
  • Patent number: 4999197
    Abstract: Compositions are prepared from carob pods which are particularly useful for the treatment of diarrhoea. To prepare the compositions, ripe carob pods are treated with an aqueous medium for extracting sugars and water-soluble tannins, the residue is separated from the liquid phase containing the extracted materials and then the residue is dried under conditions which avoid thermal denaturing of the water-insoluble tannins contained in the residue. The compositions contain water-insoluble native tannins in an amount of at least 20% by weight, based upon dry matter, expressed as total polyphenols and have a ratio of water-soluble to water-insoluble tannins of below 0.37 as determined in water at 37.degree. C. The dried residue is ground to a particle size up to 200 .mu.m in diameter and may be formulated with food-acceptable additives.

  • Patent number: 4939123
    Abstract: Adherence of pathogenic bacteria having type I fimbriae to animal cells is inhibited by compositions having active constituents which are new glycopeptide and/or oligosaccharide compounds. The active constituent compounds are prepared enzymatically from vegetable flour which contains reserve glycoproteins rich in oligomannosides, preferably from a fraction enriched with soya glycoprotein 7S or with bean glycoprotein II, although glycopeptides from ovalbumin may be utilized for the preparation of the compounds. The compounds have a polymannosidic basic structure similar to that of epithelial cells which is recognized by various pathogenic bacteria and which results in neutralizing the bacteria so they do not adhere to the cells. Compositions including the active constituent compounds are effective for use in the prophylaxis, treatment and diagnosis of infectious diseases, especially those caused by coliform bacteria, and also for use in the disinfection of surfaces.

  • Patent number: 4853248
    Abstract: Instant dehydrated purees of seeds of leguminous plant with retarded intestinal resorption in the form of flakes or granules are prepared by rehydrating dry seeds of the leguminous plants, cooking the rehydrated seeds, reducing the cooked seeds to a puree and drying the puree by carrying out these steps such that the cell walls of the seeds, particularly the cell walls of the cotyledon, are damaged as little as possible. To prepare the dehydrated puree, dry seeds are rehydrated by soaking and then the rehydrated seeds are cooked, reduced to puree and dried.
