Scientists from the USA's Agricultural Research Service are trying to improve the taste of reconstituted orange juice in order to match the flavour of freshly squeezed orange juice that most consumers prefer.

To do this, researchers had to isolate 40 "flavour aroma compounds" that make freshly squeezed OJ taste the way it does. These elements were then introduced to a deodorised form of orange juice, and given to taste testers.

Tasters had to describe the different smells, which they said varied from paint thinner to the scent of roses. The researchers will now mix and match combinations of compounds to allow manufacturers to better mimic that freshly squeezed taste.

Companies such as Tropicana and Coca-Cola North America have shown interest in the project and have agreed to support it.
