However, thickened beverages have poor compliance among patients, primarily due to a dislike of the taste and flavor. While thickeners produce a higher viscosity, which helps reduce the risk of aspiration, there is evidence that they also reduce taste sensations. Previous research suggests that rheological properties might explain the impact on taste perception; however, recent findings do not demonstrate this interaction. Therefore, this study aims to explore the impact of Nestle ThickenUp Clear on the taste intensity of sucrose (sweet), citric acid (sour), and NaCl (salty) when mixed at three concentrations compared to an unthickened control. The samples were analyzed for rheological properties (including viscosity and tan delta). A total of 56 untrained healthy participants completed the Temporal Check All That Apply (TCATA) and rated taste intensity and liking. This study presented significant findings on physical textural properties and sensory aspects; most importantly, Linear Mixed Models (LMM) revealed that saltiness (<i>β</i> = −4.16), sourness (<i>β</i> = −3.29), and sweetness (<i>β</i> = −3.43) all decreased significantly with the addition of thickener (<i>p</i> &lt; 0.001), with the magnitude and slope varying considerably for each tastant. However, viscosity did not result in a decrease in taste intensity (as indicated by a lower marginal <i>R</i><sup>2</sup> than conditional <i>R</i><sup>2</sup>). These findings emphasize that unique interactions between tastants and thickeners drive taste perception, rather than being solely determined by physical rheological measures (such as viscosity and viscoelasticity).

In addressing these issues, factors influencing firmness characterization, including peeling, probe size, penetration speed, penetration depth, and measurement parameters were analyzed for peach and nectarine. The results show that, compared to skin-off parameters, skin-on parameters exhibited absolute advantages for the nectarine cultivar. We also found the importance of probe size selection for accurate firmness detection for different cultivars, and it appears to be closely related to whether the fruits were peeled. The peach cultivar “HJ” is suitable for using a thicker probe (8 mm) after peeling, while the nectarine cultivar “ZNJH” is suitable for using a relatively thin probe (5 mm) with the skin on. The influence of speed is relatively low; however, a penetration speed of 5 mm/s is more recommended due to its better performance in capturing firmness differences. The force values at the steady phase of force-displacement curves perform best among all tested parameters.

The diffusion coefficients were determined using two approaches. First, they were experimentally measured in a model matrix using dynamic light scattering (DLS) at 60°C, 70°C, and 80°C and subsequently extrapolated to the frying temperature (180°C) using the Arrhenius equation. Second, the effective diffusion coefficients were calculated based on Fick's law of diffusion. All chips were fried to a low moisture content (~1%–2%), but fat contents ranged widely from about 32% to 43% depending on the oil used. Chips fried in the highly saturated palm olein absorbed the least oil (~32%) and had the highest hardness (peak force), whereas those fried in polyunsaturated sunflower oil had the highest oil content (~43%) and lowest hardness. Diffusion coefficient measurements in the model system also differed by oil type (e.g., sunflower oil showed the lowest molecular diffusion rate), although the calculated effective diffusion coefficients of oils into chips were of similar order (~10<sup>−6</sup> m<sup>2</sup>/s) for all oils. The correlation analyses revealed strong correlations between oil diffusion coefficients and chip moisture, fat content, and texture, highlighting the role of oil mobility in determining product quality.

It is typically induced by polyphenol-rich foods and beverages such as wine and tea. The quantitative assessment of astringency intensity has become a prominent research focus in the food science field. In this study, an in vitro oral tribological method was developed based on a soft–hard friction interface. An oral-like sensory structure was constructed using biomimetic materials to replicate tongue–palate contact. The frictional behavior carried out in this structure is similar to that of the palate-tongue friction contact in the oral cavity. Thus, the structure allows for the detection of the effect of changes in the nature of food in the oral cavity on the tongue and the palate, which can be quantified by the coefficient of friction. Porcine gastric mucin (PGM), which shares functional similarities with salivary proteins, was employed as a model sensory material. This allowed the device to capture the interaction mechanisms between astringent compounds (e.g., tannins) and salivary proteins. A calibration curve was established by fitting friction coefficient data across a range of tannin concentrations. Subsequently, commercial wine samples were tested. The tribological system detected changes at the mucin–wine soft–hard interface, and the measured friction coefficient served as a quantitative indicator of astringency intensity.

We therefore hypothesized that rats can discriminate textures based on mechanical properties-springiness and hardness-independent of taste, odor, and visual cues. To investigate texture perception, we evaluated rats' discrimination of agar gels using a conditioned texture aversion paradigm with a two-bottle preference test. Agar gels at 1%–3% concentrations were cut into 5 mm cubes or strained through a 100-mesh sieve to form paste. In the two-bottle preference test comparing 1% and 3% agar cubes, the conditioned stimulus (CS) applied to the cubes induced selective aversion to the CS cubes, but the CS applied to the paste form eliminated this aversion. Moreover, to exclude taste or odor cues, gelatin cubes with physical properties similar to those of the 3% agar cubes were prepared, and conditioning with these gelatin cubes induced aversion to the 3% agar cubes. To eliminate visual cues, resin cubes resembling agar cubes were prepared; however, conditioning with the resin cubes did not produce aversion to agar cubes. These results indicated that aversion learning to the agar cubes was acquired based on textures rather than taste, odor, or visual properties.

Initially, the number of cycles required to chew each food sample for swallowing was recorded through in vivo experiments. Subsequently, various molar chewing trajectories, occlusal forces, and artificial saliva flow rates were applied in the robotic chewing system to simulate a range of chewing behaviors. Each food type was chewed by the robot for 0%, 25%, 50%, 75%, and 100% of the total determined number of chewing cycles. Nine food texture variables were measured using texture profile analysis (TPA). Principal component analysis (PCA) and partial least squares regression (PLSR) were employed to assess the correlations between chewing behaviors and food texture changes. Results showed that for roasted peanuts, hardness, adhesive force, and cohesiveness had strong correlations with chewing cycles, while for white bread, these relationships were less pronounced. The mechanisms underlying the texture changes were analyzed and explained. For roasted peanuts, texture changes were primarily governed by chewing stages, with an average hardness reduction of 81.5% over the chewing process. Springiness and its index were mainly influenced by saliva secretion rate. Conversely, white bread initially exhibited increased hardness due to compression, followed by gradual softening. Its adhesive force was chiefly impacted by saliva secretion, while cohesiveness was more strongly affected by chewing trajectory.
