Ice cream

Ice cream requires opposite functionalities from an emulsifier. That is why a combination of different emulsifiers will give the best result.

Stable

In the liquid mix, an emulsifier with a high HLB value (like sucrose esters) is best. Sucrose esters will quickly replace the proteins from the fat globule (aging can be shorter). The mix is stable; no fat separation and no churning.

In-stable 

When the product is aerated, the emulsion should be destabilized slightly, in order to form a fat-network around the air cells. Emulsifiers with a low HLB value are more suitable for this part.

The best results are reached by combining sucrose esters with low HLB emulsifiers like MDG or α-tending emulsifiers (e.g. lactic acid esters).

Flavour

Besides technical benefits, sucrose esters will give ice cream a fresh, and less greasy mouthfeel. Flavours will be much more pronounced. 

Benefits

  • Shorter aging time
  • Stable liquid mix
  • Easy aeration
  • Improved flavour release
