Currently little is known about how the non-edible items associated with eating and drinking (tableware items such as the plates, bowls, cutlery, glasses, bottles, condiment containers, etc.), or even environmental factors (such as the lighting and/or background music), affect people's perception of foodstuffs. Here, we review the latest evidence demonstrating the importance of these contextual variables on the consumer's behavioural and hedonic response to, and sensory perception of, a variety of food and drink items. These effects are explained by a combination of psychological factors (high level attributes, such as perceived quality, that may be mediating the effects under consideration), perceptual factors (such as the Ebbinghaus-Titchener size-contrast illusion and colour contrast in the case of the colour of the plateware affecting taste/flavour perception), and physiological-chemical factors (such as differences in the release of volatile organic compounds from differently-shaped wine glasses). Together, these factors help to explain the growing body of evidence demonstrating that both the tableware and the environment can have a profound effect on our perception of food and drink.Keywords: Cutlery, Tableware, Contextual factors, Flavour, Liking, Multisensory, Weight, Colour, Size, Material
ReviewResearch on the topic of flavour perception has grown rapidly over the last decade or so (see Figure 1). In particular, the relative contributions of the various sensory cues (i.e., olfactory, gustatory, somatosensory, auditory, visual, and trigeminal) to multisensory flavour perception have been examined for a wide variety of different food and beverage items (see [1,2] for reviews). While a number of recent studies have also highlighted the importance of atmospheric/environmental cues in determining what, how much, and how quickly, we eat and drink, and even how much we report liking the experience ([3,4]; for reviews, see [5,6]), far less research has studied the role of the tableware on eating, drinking, and flavour perception. Below, we review the latest evidence highlighting the significant effect that the non-edible components of eating and drinking (e.g., the cutlery, plateware, glassware, condiment containers, menus, and atmosphere) can have on people's perception of, and response to, foods and beverages.
CutleryCutlery, by which we mean forks, knives, and spoons, has been in widespread use for nearly 200 years now (e.g., [7,8]). Traditionally, it was made from a wide variety of different materials, such as wood, bone, ceramic, iron, brass pewter, etc. Nowadays, though, the range of materials used for cutlery is much narrower, mainly limited to stainless steel, silver, plastic, or wood (for chopsticks and the cutlery often found in ecofriendly coffee shops). This streamlining of materials has probably resulted from a combination of factors including: the ease and cost of manufacture/production, the ease of cleaning, environmental impact, and any taste transferred from the cutlery to the food.Lau...
