  • Patent number: 8192845
    Abstract: The present disclosure relates to compositions consisting essentially of starch and lecithin. The disclosure also relates to processes for preparing the compositions consisting essentially of a starch and lecithin. Further, the disclosure relates to uses of compositions consisting essentially of starch and lecithin, or compositions comprising starch and lecithin, in the preparation of paper products that have oil and grease resistant properties, and/or release properties. Further, the disclosure relates to paper products that include lecithin-containing compositions and to paper products resulting from the processes herein.

  • Patent number: 7413881
    Abstract: A highly deacetylated chitosan obtained from microbial biomass, a method of obtaining chitosan from microbial biomass, and biomass for making chitosan are disclosed. The method includes providing chitin-containing biomass; reacting the chitin-containing biomass in a caustic solution of greater than 25 percent alkali at a reaction temperature greater than 95° C. for a reaction period of at least 10 hours to convert the chitin in the biomass to chitosan; and separating the chitosan from the caustic solution.
    Type: Grant

  • Patent number: 7049433
    Abstract: Glucosamine suitable for human or animal consumption is disclosed. The glucosamine is derived from microbial biomass containing chitin. Suitable starting materials include substantially uniform microbial fungal sources, such as fungal sources derived from Aspergillus sp., Penicillium sp., Mucor sp. and combinations thereof. Methods of producing glucosamine by acid hydrolysis of fermented fungal biomass are also disclosed.
    Type: Grant

  • Patent number: 6693188
    Abstract: The present invention is directed to N-acetyl-D-glucosamine obtained from microbial biomass, and to methods of obtaining N-acetyl-D-glucosamine from microbial biomass. In particular, the present invention is directed to the use of fungal biomass to create N-acetyl-D-glucosamine. The N-acetyl-D-glucosamine is efficiently obtained at high purity by degrading chitin in the fungal biomass to create N-acetyl-D-glucosamine.
