Chocolate can be described as a suspension consisting of non-fat particles (sugar, cocoa solids and milk powder particles) dispersed in cocoa butter and a portion of milk fat as a continuous phase. Its unique pleasant taste is produced by a complex interaction of odour-active volatile compounds, which are supplementary to the fine bitterness of cocoa and the sweetness of sugar. The characteristically pleasant mouth-feel is produced by the melting behaviour of cocoa butter, its flavour release and the rheological properties of the melting mass.

Transparent plastic packaging is increasingly replacing traditional food packaging made of glass and metal. The advantages of transparent plastic packaging are; its low weight, low cost, design flexibility and the opportunity to present products in an attractive way. However, compared to traditional packaging made of glass, metal, aluminum-laminated films or metallised films, transparent plastic packaging provides less protection against light and also in many cases, a poorer barrier against oxygen.
