The method is also applicable to concentrated and dried ice mixes. The method is not applicable to some milk-based edible ices and ice mixes, in which the level of emulsifier, stabilizer or thickening agent or of egg yolk or of fruits, or of combinations of these constituents makes the Roese-Gottlieb method unsuitable.
