Bibliography

ISO 7328¦IDF 116:2008 specifies the reference method for the determination of the fat content of most milk-based edible ices and ice mixes.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.
