    • A display comprising at least two cavity structures 40 substantially juxtaposed, the interiors of the cavity structures 40 being respectively coloured, at least in part, with a test colour and a reference colour, wherein the test colour is related to the reference colour in that it has a substantially similar or the same hue characteristic, but a different lightness characteristic. The cavity structures 40 may be boxes, paint cans, miniature rooms or full-sized rooms. The interior of the cavity structures 40 may be viewed through apertures 46 and may be illuminated by lamps 27. The two cavity structures 40 preferably have the same size and configuration and may have objects inside of them arranged in the same manner. The interiors of the cavity structures 40 may be painted or be fitted with coloured inserts to display the test and reference colours. The test and reference colours may have the same or similar chroma characteristics and the reference colour may be selected from a colour-difference algorithm, possibly a CIE algorithm in dependence on the characteristics of the test colour, using higher weighting values for hue and chroma values. A second invention defines a test determining viewer perception of cavity size using the display, with the lighter test colour supposedly making the cavity look bigger.

    • The present invention relates to an artificial throat for simulating aroma release comprising - a tube (1) having an inlet (2) and an outlet (3) and having an upper portion (4), a middle portion (5) and a lower portion (6); - a sample supply system (12) debouching at the upper portion of the tube; - an inlet closure (9) for closing and opening the inlet; - an outlet closure (10) for closing and opening the outlet; - a gas ventilation system (13) debouching at the lower portion of the tube for providing a gas flow, such as an air flow, through the tube. The invention also relates to an assembly for simulating and analyzing aroma release comprising an artificial throat and an analyzing apparatus, such as a mass-spectrometer. Furthermore the invention relates to a method for simulating and analyzing aroma release by means of an artificial throat. Aroma release according to the invention means the release of volatile compounds from substances such as food and drinks, which compounds are transported by means o a gas flow.
