Individual differences in oral tactile sensitivity and gustatory fatty acid sensitivity and their relationship with fungiform papillae density, mouth behaviour and texture perception of a food model varying in fat

•Individuals differ in papillae density, oral tactile and fat taste sensitivity.•Fungiform papillae density positively correlates with oral tactile sensitivity.•Higher fungiform papillae density related to higher fat taste sensitivity.•Fungiform papillae density and tactile sensitivity influence mouthfeel perception.•BMI related to oral tactile sensitivity and perception of greasy.
