1.Promote the destabilising of the mix during freezing
2. Act as nuclei for the crystallisalion of high melting fat.
3. At certain temperatures, can form various mesophases at the interface.
4. Improve whipping quality of the mix (overrun)
5. More efficient air incorporation
6 .Production of a drier ice-cream,
7. Smoother body and texture.
8. Superior scooping qualities at the freezer
9. Better control over various manufacturing processes(extruding and packaging).
10 Increased melt time.
11. Lower surface tension.
12. Reduction in whipping time.
13 Produce somewhat smaller ice crystals more evenly distributed and smaller air cells which result in a smoother ice cream.
Many factors could affect the action of an emulsifier in ice-cream such ingredients used, procedure of processing. freezing, hardening homogenisation and the level and type of emulsifier and stabilisers used
