Ice cream is complex-colloidal systems which in their frozen
state is comprised of ice crystals, air bubbles, partially-coalesced fat
globules and aggregates, all in discrete phases surrounded by an
unfrozen continuous matrix of sugars, proteins, salts, polysaccharides
and water . Ice cream contains a high concentration of fat , which is considered
a multifunctional ingredient and influences the creaminess, texture, mouthfeel , color and flavor of these products . Fat contributes to the properties of ice cream during freezing and beating, especially through the formation of a three-dimensional
network of partially-coalesced fat globules. Some of the fat globules surround air bubbles, stabilizing the air phase and increasing the levels of fat aggregation, thus improving the melting resistance and ice recrystallization.
