  • Patent number: 7838666
    Abstract: A material is provided to give food products sufficient viscosity and stability (heat resistance, stable suspension, etc.). The material is produced from an inexpensive raw material by an economical process. Further, a novel gel containing cellulose as the main component is also provided. The present invention provides a fine fibrous water-dispersible cellulose derived from plant cell walls. For the production, a raw material having specific properties is used, and size reduction is carried out stepwise thereto. The water-dispersible cellulose can also be made into a dry composition by compounding with a water-soluble polymer or the like. This dry composition forms a gel when combined with a polysaccharide such as glucomannan or the like. The gel excels in heat-resistance and shape-retention and can be used to produce to novel food products.

  • Patent number: 6495190
    Abstract: A cellulose-containing composite contains 20-99% by weight of a fine cellulose and 1-80% by weight of at least one low-viscosity water-soluble dietary fiber selected from the group consisting of 1) a hydrolyzed gallactomannan, 2) an indigestible dextrin and 3) a mixture of a polydextrose and xanthan gum and/or gellan gum, wherein the total amount of gellan gum and xanthan gum is 0.1% by weight or more but less than 3% by weight of the composite, in which composite the average particle size of the fine cellulose is 30 &mgr;m or less when the composite is dispersed in water.
