Mouthfeel

For the album, see Mouthfeel (album).

A child bites into a watermelon, experiencing mouthfeel sensations such as juiciness

Mouthfeel refers to the physical sensations in the mouth caused by food or drink, making it distinct from taste. It is a fundamental sensory attribute which, along with taste and smell, determines the overall flavor of a food item. ^{[1] [2]} Mouthfeel is also sometimes referred to as texture. ^[2]

It is used in many areas related to the testing and evaluating of foodstuffs, such as wine-tasting and food rheology. ^[3] It is evaluated from initial perception on the palate to first bite, through chewing to swallowing and aftertaste. In wine-tasting, for example, mouthfeel is usually used with a modifier (big, sweet, tannic, chewy, etc.) to the general sensation of the wine in the mouth. ^[4] Research indicates texture and mouthfeel can also influence satiety with the effect of viscosity most significant. ^[5]

Mouthfeel is often related to a product's water activity—hard or crisp products having lower water activities and soft products having intermediate to high water activities. ^[6]

Qualities perceived

• Chewiness: The sensation of sustained, elastic resistance from food while it is chewed
• Cohesiveness: The degree to which the sample deforms before rupturing when biting with molars
• Crunchiness: The audible grinding of a food when it is chewed
• Density: The compactness of cross section of the sample after biting completely through with the molars
• Dryness: The degree to which the sample feels dry in the mouth ^[7]
• Exquisiteness: The perceived quality of the item in question
• Fracturability: The force with which the sample crumbles, cracks or shatters – Fracturability encompasses crumbliness, crispiness, crunchiness and brittleness.
• Graininess: The degree to which a sample contains small grainy particles
• Gumminess: The energy required to disintegrate a semi-solid food to a state ready for swallowing
• Hardness: The force required to deform the product to a given distance, i.e., force to compress between molars, bite through with incisors, compress between tongue and palate
• Heaviness: The weight of product perceived when first placed on tongue
• Juiciness
• Moisture absorption: The amount of saliva absorbed by product
• Moisture release: The amount of wetness/juiciness released from sample
• Mouthcoating: The type and degree of coating in the mouth after mastication (for example, fat/oil) ^[8]
• Roughness: The degree of abrasiveness of product's surface perceived by the tongue
• Slipperiness: The degree to which the product slides over the tongue
• Smoothness: The absence of any particles, lumps, bumps, etc., in the product
• Tenderness: The opposite of hardness; ease of chewing
• Uniformity: The degree to which the sample is even throughout or the homogeneity of the sample
• Uniformity of bite: The evenness of force throughout the bite
• Uniformity of chew: The degree to which the chewing characteristics of the product are even throughout mastication
• Viscosity: The force required to draw a liquid from a spoon over the tongue
• Wetness: The amount of moisture perceived on product's surface
