It has been generally assumed that fat is detected by its flavour and by its lubrication of the oral mucosa. A recent study reported a correlation of -.99 between perceived temperature of a product and its fat content. This was significantly higher than correlations of sensory scores for fat flavour, mouthfeel, and afterfeel. This suggested a...

The intra-oral processing of semi-solids foods is dominated by effects due to tongue movement. These movements subject the food to shear forces and mix it with saliva. Both actions tend to reduce the viscosity of the products. These changes are perceived as "melting" by sensory panellists. In a previous study where subjects were trained to use a...

Sensitivity to 6-n-propylthiouracil (PROP) for a group of 180 naïve consumers was related to their perception of 16 commercially available vanilla custard desserts. Rated intensities of taste and texture attributes varied moderately and inconsistently with PROP sensitivity. In contrast, discriminative ability increased with PROP sensitivity...

Perceived fattiness and creaminess plus other texture and flavor attributes were assessed for a group of vanilla custard desserts, white sauces, and mayonnaises that differed widely in ingredients, fat content (0-72%), and consumption temperatures. In addition, the foods were measured instrumentally with regard to their lubricative properties,...

Saliva is expected to be of significance for the perception of food stimuli in the mouth. Mixing the food with saliva, including breakdown and dilution, is considered to be of large importance for semi-solids as these products are masticated without chewing. It is known that there are large variations in composition of saliva originating from...

Frictional conditions in the mouth are thought by food scientists to be critical to the perception of important food attributes such as astringency, smoothness, roughness, slipperiness, etc. This ability to detect friction probably evolved to avoid foods that could wear the teeth excessively. In modern humans, sensations related to friction and...

The relevance of initial rheological properties and mechanical and enzymatic structure breakdown in determining selected sensory texture attributes of custards was studied. The so-called structure breakdown cell was used to characterize saliva-induced breakdown, i.e., by monitoring digestion of starch by amylase from saliva. Based on rheological...
