Abstract
A lipophilic mass is liquefied or ground to a powder and there is incorporated therein by blending a foam of fine air or gas bubbles in water, then it is allowed to cool and degas. The foam is stabilized by the addition of a foamer, for instance an amphipatic surfactant, and may contain viscosity enhancers and thickeners. The method is applied to the hydration of chocolate in order to improve its storage stability and heat resistance; the foamer can be a whipped solution of egg-white or of esters of fatty acids with polyols.
