The present invention discloses a dried composition comprising &#x3b2;-casein micelles, assemblies and complexes thereof. The dried composition is stable in the dried state as well as upon re-suspension The dried composition retains the biological activity, drug load capacity, particle size and particle size distribution of the &#x3b2;-casein micelles, assemblies and complexes comprising the active pharmaceutical ingredient, within the dried state and upon resuspension in a buffer or an aqueous pharmaceutical carrier.

Beta-casein assemblies for mucosal delivery of therapeutic bioactive agents

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.

Beta-casein assemblies for enrichment of food and beverages and methods of preparation thereof

Nanoparticulate assemblies of isolated beta-casein, are useful for encapsulation of bioactive therapeutic substances, particularly therapeutic agents with poor bioavailability. These nano-sized beta-casein assemblies are preferably formed at pH values which are at least one or more pH units below or above the pI of the protein. Pharmaceutical compositions comprising the beta-casein micelles may be used to administer the agents to the GI tract for treatment of local or systemic conditions. These carriers are stable over a wide temperature range (optionally at least from about 1&#xb0; C. to at least about 45&#xb0; C.).
