  • Patent number: 10292927
    Abstract: Microfibrous cellulose (MFC) broths are provided having improved performance as compared to wet cake microfibrous cellulose (MFC) and powdered microfibrous cellulose (MFC). In embodiments, compositions having an effective amount of an MFC broth and an effective amount of a surfactant have an improved yield value as compared to a composition having a surfactant and a wet cake MFC, a powdered MFC, or a combination thereof at the same concentration as the MFC broth. Also, methods are provided for improving the yield value of surfactant compositions by adding an effective amount of a microfibrous cellulose broth to an effective amount of surfactant to provide a surfactant composition having a yield value that is higher than a composition having the surfactant and a wet cake MFC, a powdered MFC, or a combination thereof at the same concentration as the microfibrous cellulose broth.

  • Patent number: 9050357
    Abstract: Compositions are provided that are suitable for safe consumption by a patient with dysphagia. In one embodiment, the compositions include a modified xanthan gum in an amount suitable to provide a viscous, free-flowing solution having gel-like properties. The modified xanthan gum comprises a non-pyruvylated xanthan gum, a reduced-pyruvylated xanthan gum, or a combination thereof. The composition desirably has a viscosity of greater than about 2000 cP and is characterized as having a shape retention of greater than about 50%. Also provided are methods for their preparation and use.

  • Publication number: 20130059032
    Abstract: A stabilizing additive for compositions, e.g., fermented milk products, is disclosed comprising xanthan gum and iota-carrageenan wherein the weight percentage of the xanthan gum in the stabilizing additive is higher than the weight percentage of the iota-carrageenan. The xanthan gum can be reduced pyruvate or non-pyruvylated xanthan. The stabilizing additive can further comprise a galactomannan. The composition can further comprise starch. Also disclosed is a method for making a fermented milk product comprising adding the stabilizing additive to milk and fermenting the milk or adding the stabilizing additive to already fermented milk. Fermented milk products comprising the additive can include, e.g., yogurt, drinkable yogurt, kefir or Ymer.

  • Patent number: 8053216
    Abstract: A new method to produce formulations of bacterial cellulose that exhibit improved viscosity-modifying properties particularly with low energy applied to effectuate viscosity changes therewith is provided. Such a method includes the novel co-precipitation with a water soluble co-agent that permits precipitation in the presence of excess alcohol to form an insoluble fiber that can than be utilized as a thickener or suspension aid without the need to introduce high energy mixing. Such bacterial cellulose properties have been available in the past but only through highly labor and energy intensive processes. Such an inventive method as now proposed thus provides a bacterial cellulose-containing formulation that exhibits not only properties that are as effective as those for previous bacterial celluloses, but, in some ways, improvements to such previous types. Certain end-use compositions and applications including these novel bacterial cellulose-containing formulations are also encompassed within this invention.

  • Publication number: 20100016575
    Abstract: A method for the production of a bacterial cellulose-containing formulation that lacks a carboxymethyl cellulose component. The method includes providing a bacterial cellulose product, mixing the bacterial cellulose product with a polymeric thickener and/or a precipitation agent, lysing the bacterial cells from the bacterial cellulose product or the mixture of the bacterial cellulose product and the polymeric thickener or precipitation agent, and co-precipitating the resultant mixture with a water-miscible non-aqueous liquid. The resultant bacterial cellulose formulation includes at least one bacterial cellulose material and at least one polymeric thickener. The bacterial cellulose formulation, may be used in food compositions.
