Natural flavour comes from a natural product that is processed to concentrate it. Various techniques can be used to extract the aromatic compounds found in nature. Some of them are really simple, like infusion, which we have all experienced. Another way to extract the aroma from the original fruit is by dehydration, removing the water from the plant or fruit, or by distillation. Extraction with a water- or alcohol-based solvent is also a very common process. All of these physical processes result in a highly concentrated liquid product that is perfectly suited to food preparation.
