    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.
