3 Taste Compared to aroma stimuli, measuring the proximal stimulus of taste compounds seems relatively facile at first. The taste receptors are located on the tongue, which can be easily accessed for direct sampling. However, the process of mastication and dilution with saliva creates a complex mixture of whole food pieces, semi-masticated particles and an unpleasant slurry of saliva/food, which bathes the tongue. It is evident that the system is not mixed to homogeneity and there are big differences in concentrations across the tongue.

The actual experience of perceiving colour occurs when the wavelengths of light, converted to a ‘code’ of electrical signals, are interpreted by the brain. Originally, it was postulated that colour vision was a result of the stimulation of a three-receptor mechanism on the basis that any colour could be made/ matched from mixing red, blue and green light. The discovery of three types of cone cells in the retina, each particularly sensitive to wavelengths representing red, blue and green, appeared to support this so-called Trichromatic theory.
