Psyllium fiber inhibited starch digestion by acting as a physical barrier and limiting enzyme mobility. Due to the structural differences between bread and crackers, they digested differently.

The debonding was believed to influence stress-strain curves of tensile and shear tests at different strain rates.

The finite element modelling results showed agreement with experimental data under uniaxial tension and simple shear at different strain rates (5/min and 0.5/min). This was due to the viscoelastic effect of the interface model, which caused difference between traction initiation at different rates for the cohesive zone model (i.e. ∼1.1kPa and ∼0.5kPa at 5/min and 0.5/min, respectively). In addition, it was shown that critical shear stress is a very important debonding parameter, where slight changes of the shear traction values caused the model stress-strain curve to deviate from the experimental results. Simulations of starch-gluten dough deformation were then conducted at different strain rates to imitate dough processes like baking, extrusion and proving (0.003/s, 1/s and 10/s, respectively).

One of the alternative sources is chicken skin, where extracted collagen properties have been shown to be influenced by the age of the chickens. In this study, the biochemical and physical properties of chicken skin collagen preparations from two different broiler strains (slow and fast-growing) and two different weights (1.6 and 2.2 kg) were investigated.

Differential Scanning Calorimetry (DSC) measurements of the dispersions showed T<sub>onset</sub> ranging from 38.7° to 39.1°C. After salt precipitation, the T<sub>onset</sub> increased to 50.1 – 55.9 °C. Mechanical strength of the films from fast and slow growing chickens ranged from 63 to 67 KPa and 53–57 KPa, respectively.

Therefore, greater value can be unlocked by functionalising these “inert” plant proteins. Using commercial insoluble pea protein isolate (I-PPI) as an example, this study demonstrates the application of high-pressure homogenisation (HPH) as a physical method to improve the techno-functionality of I-PPI. The dispersions were HPH-treated at 60, 120, or 180 MPa for one, three, and five pressure cycles. HPH treatments resulted in decreased particle size (from 16.7 ± 1.3–9.4 ± 0.2 µm at 60 MPa) and increased zeta-potential. Microstructural observations revealed the formation of smaller aggregate clusters and flake-like structures after HPH treatments. The protein solubility of I-PPI (15.9 ± 2.0 %) under acidic conditions (pH 2) significantly increased at all HPH treatment levels, with the greatest increase at 120 MPa for 5 passes (27.2 ± 2.0 %). Remarkably, the non-gelling I-PPI was able to form self-standing gels (15 % w/w) after HPH treatments, with the greatest gel strength observed at 180 MPa. The emulsifying and foaming stability of HPH-treated I-PPI increased from 60 to 120 MPa but decreased at 180 MPa.

Plasma acetaminophen was only correlated with antrum measurements for the intragastrically stable emulsion with liquid lipid droplets (P = 0.041, r = −0.69). The US results support the role of colloidal stability in delaying GE and the images showed different gastric phase behaviours. In contrast, acetaminophen solubility confounded the results when the emulsions were susceptible to acidic flocculation. US antrum measurements (but not the acetaminophen results) were also correlated with participant subjective satiety (P < 0.0001), supporting the close mediation of satiety perception by antral distention.
