  • Publication number: 20140322340
    Abstract: The present invention provides protein (or peptide)-polysaccharide (or oligosaccharide) conjugates (PPC) as nanocapsular vehicles for nanoencapsulation of biologically active compounds, particularly nutraceuticals. The PPCs efficiently protect both hydrophobic (i.e., water insoluble) and hydrophilic (i.e., water soluble) nutraceuticals, to provide a composition which, when added to a beverage, disperses so as to provide a clear or transparent solution. In some embodiments, the PPCs are Maillard reaction based PPCs. Advantageously, the conjugates of the present invention protect the nutraceuticals from degradation, both during shelf life and upon gastric digestion.

  • Patent number: 8865222
    Abstract: The invention relates to a composition for the enrichment of food and/or beverage and to a method of preparing such composition. The composition comprises additive loaded beta-casein micelles which are of a diameter of about 100 nm or less. These nano-sized beta-casein assemblies are formed at pH values which are preferably one or more pH units above or below the pI of the protein (pI=5.3). More preferably the beta-casein nano-assemblies are formed at a pH range between about 6.0 and about 8, or between about 2.0 and about 4.2. The invention provides vehicles for delivery of additives via transparent beverages and other foods and drinks and/or acidic foods and drinks and/or non fat foods and drinks.

  • Patent number: 8791064
    Abstract: The present invention provides colloidally stable dispersions of nanoparticles comprising beta-lactoglobulin and a polysaccharide which are transparent when diluted in aqueous media. In particular these colloidally stable dispersions of nanoparticles are useful as delivery vehicles of hydrophobic nutraceuticals and fat-soluble vitamins, for enrichment of food products, especially of transparent beverages and other non-fat or low fat foods and drinks. The present invention further provides methods for the preparation of said colloidally stable dispersions.
