Abstract
A composition is formed by compounding a first substance with a second substance. The first substance includes a bicarbonate, an acid or a combination thereof. The second substance includes a frothing agent, a coating agent or a combination thereof. The composition may be formed into coated particles or a mass of particles coated by a matrix, such as a matrix of the frothing agent. The particles or mass of particles may have more than one coating. The compound is used for preparing a stable froth on a beverage, such as a hot cup of cappuccino. The frothing agent may include not only compounds that enhance the stability of the foam but also compounds that enhance other characteristics of a desirable froth. The coating agent may be used to delay the reaction between a bicarbonate and an acid when the compound is added to water, such that a large volume of froth is produce, but undesirable flocculation, turbidity and increases in viscosity are avoided.
