This study investigates the formulation of <em>four</em> 20 wt% oil-in-water (O/W) emulsions: PPI emulsion (4 wt% PPI), PG emulsion (4 wt% PG), PPI-PG emulsion (2 wt% each in aqueous phase), and a 1:1 mixture of individually prepared PPI and PG emulsions (PPI/PG). The emulsions underwent thermal processing to induce particle aggregation and heteroaggregation, followed by <em>in vitro</em> digestion and <em>ex vivo</em> absorption using a rat small intestine model. The mixed emulsions exhibited significantly higher viscosities and moduli than single emulsions, along with larger and denser microstructures. Consequently, free fatty acids (FFAs) released at the end of digestion were lowest for PPI-PG (33.7 %), followed by PPI (44.92 %), PG (39.93 %), and PPI/PG (36.32 %). Correspondingly, <em>ex vivo</em> FFA absorption was slower for PPI-PG (9.83 %) and PPI/PG (10.81 %) than for PG (14.95 %) and PPI (16.33 %), reflecting reduced enzyme accessibility due to stronger interfacial structures.

In this study, nanoparticles were prepared from pectin and sodium caseinate to deliver resveratrol and curcumin using a solvent evaporation method combined with electrostatic deposition, and their physicochemical and structural properties were characterized. The nanoparticles (PE-SC-C-RNP) had a narrow size distribution (247.57 nm), low polydispersity index (0.32), and high encapsulation efficiency (95.24 ± 0.76 %). Structural analyses indicated that electrostatic interactions between pectin and sodium caseinate formed the nanoparticle outer layer, with resveratrol and curcumin in an amorphous state. <em>In vitro</em> digestion experiments showed that curcumin enhanced the binding of resveratrol to carriers without affecting the release rate of resveratrol or free amino acids, leading to a significant increase in antioxidant activity. Animal model experiments showed that the resveratrol concentrations were greater in the plasma of mice administered PE-SC-C-RNP than those administered nanoparticles encapsulating only resveratrol orally, with a 0.83–1.27-fold increase in the maximal tissue concentration, and better pharmacokinetics. The maximum tissue concentration of resveratrol increased 0.83–1.27-fold in the liver, kidney, and other tissues within 6.0 h of administration.

In this study, the effect of dasher design and processing parameters on the residence time distribution (RTD) of ice cream made in a continuous SSF was investigated. Processing parameters investigated included dasher speed, overrun, and throughput rate, while five dasher designs of varying geometries and volume displacements within the freezing cylinder were employed. Dye pulse injection studies were used to determine RTD properties while monitoring processing conditions including draw temperature, overrun, and amperage drawn on the dasher motor. Mean residence time was primarily driven by throughput rate, followed by dasher assembly, and then overrun. Reduced mean residence time was associated with higher throughput rates, higher dasher displacements, and lower overrun. Dasher rotational speed did not have a significant effect on mean residence time. There were two-way interaction effects between dasher design and dasher rotational speed, overrun, as well as throughput rate on residence time parameters (mean and/or variance).

As the concentration of CNFs increased, the stability and viscoelasticity of the emulsions gradually improved, while the droplet size decreased. The addition of more CNFs led to the formation of a denser interfacial film on the surface of the emulsion droplets and created a more extensive three-dimensional network structure in the continuous phase of the emulsion, enhancing the structural stability of the emulsion and reducing droplet aggregation and sedimentation. Furthermore, the environmental stability of the Pickering emulsions was tested by altering the pH and environmental temperature. The emulsions exhibited good environmental stability in acidic conditions (pH 2 to 6), and were able to adapt to a wide temperature range (−25 to 100 °C).
