  • Patent number: 5882716
    Abstract: A soluble coffee beverage powder which, upon the addition of water, is capable of forming a coffee beverage having a foamed upper surface. The soluble beverage powder is made up of a soluble whitener powder containing gas and a soluble coffee powder of delayed water solubility. Upon addition of water, the soluble whitener powder dissolves first and hence it is possible to obtain whiter, stable foams.
