Evolution of the nanotech revolution
Since nanotechnology was first used to develop the 'seed pre-crystallisation' technique in chocolate, many companies have been investing in the new technology to transform processing methods and product formulation.
Nanotechnology refers to the technique of controlling and manipulating matter at near atomic scales to create new processes, materials and devices. Given consumer scepticism, companies and regulators will have to be wary of their concerns in pursuing the technology.
Erich Windhab, a scientist at the Swiss Federal Institute of Technology's food processing laboratory, emphasises the need for caution in proceeding with introducing new products.
Windhab, is famous in Switzerland for developing a process during the late 1990s to prevent the greying of chocolate over time due to the recrystalisation of the cocoa butter.
