Whipped toppings are ‘fat foams'; upon whipping some fat is released from the fat globules. This fat ‘glues' a network of fat globules. Air is entrapped in this network thus creating the foam.
Emulsifiers have two (opposite) functions: creating a stable emulsion before whipping and destabilizing this same emulsion upon whipping to create some free fat. Thus usually two types of emulsifiers are used for the two different functions; stabilising emulsifiers and de-stabilising emulsifiers.
Sisterna sucrose esters
Sucrose esters are stabilising emulsifiers and can be combined with e.g. lactic acid esters for destabilisation. A good balance is important to create a topping with a good liquid stability, short whipping time, high overrun and good foam stability.
- Improved stability before whipping
- High foam volume
- Fine foam texture
