Inspired by foams in everyday products such as food, researchers in the UK have developed a way to form extremely stable temperature-sensitive air-in-oil foams.
Air-in-oil foams are widely used in industry, and feature regularly in everyday life. A typical example is aerated chocolate, formed from molten cocoa butter. Not only does the light texture provide a pleasant sensation in the mouth, but introducing air into products allows companies to manufacture foods with a lower fat content for less money. Oil foaming is also responsible for the phenomenon that cuts off the pump when refuelling vehicles. Despite this familiarity with air-in-oil foams, information on the science behind them is still lacking. Read the full article in Chemistry World»
