Abstract
The present invention relates to dry particulate encapsulation compositions comprising a water-insoluble matrix comprising at least 70% by weight of proteins, based on the total weight of the matrix and a moisture content of about 5 to 10% by weight, based on the total weight of the matrix and an encapsulate encapsulated in the matrix, wherein the matrix once wetted in a clear colorless aqueous solution or in mineral oil has a lightness value (L*) greater than about 40, a color vividness or Chroma (C*) lower than about 33 and a hue angle between about 70 and 90. The encapsulation compositions of the present invention are useful in encapsulating dyes, medications and vitamins. Fine particulate encapsulation compositions comprising natural dyes can be used in lieu of artificial lakes in confectionery, cosmetics and caplets color coatings.
