“…The fitted n <1 and DR is high (Table S2), exhibiting the excellent shear thinning performance, especially GBP5 possessing the lowest n and the highest DR , among GBP1‐GBP5. The appropriate sorbitol in GBP5 could effectively stabilise the system matrix and enhance the relative movement between molecular chains (Lobovský et al ., 2021). Under different temperatures, the viscosity of samples at 10 s −1 is illustrated in Fig.…”

SummaryThe stability of gardenia blue is challenged under light and heat. Gardenia blue was designed to be microencapsulated using gelatin, magnesium stearate and sorbitol, and the stabilization effects and food application were investigated. Effect of sorbitol was studied by CIELab colorimeter, particle size meter, SEM, absorbance, FTIR, XRD, Raman spectrum, and rheometer. Appropriate‐content sorbitol could effectively enhance color, help maintain a low nano size structure, and promote the UV irradiation stability of gardenia blue encapsulated complex systems, which is mainly owing to the hydrogen bonding, electrostatic interactions and hydrophobic interactions among components. These interactions induced by sorbitol also facilitated the shear‐thinning properties and excellent thermal stability of the complex systems. When writing & drawing on food, and 2D/3D printing food, the complex sample demonstrated the clear color and outstanding effects. The gardenia blue microencapsulated complex systems provide some reference for stabilizing natural functional materials and illustrates potential application value in food decoration and food functionalization.

“…The LBM in a numerical method which mimics the Navier-Stokes equation based on a kinetic approach [27]. Although the LBM is a more recent development compared to alternative simulation approaches in computational fluid dynamics, such as the finitevolume and finite-element methods, it is now well established and considered as an alternative to the conventional approaches, and it includes blood flow [28][29][30][31][32][33][34] and non-Newtonian [35][36][37][38][39][40][41][42] simulations. It is considered to have a number of advantages over conventional methods [43]: incorporation of microscopic interactions, particularly for simulating complex fluids such as colloidal suspensions, bubbles, solid particle suspension and polymer-solvent systems [44]; suitability for parallel computing; and, of particular reliance to this study, dealing with complex boundaries [43] and implementing non-Newtonian fluid models in an efficient manner, as will be seen in Section 2.1.…”

Blood is a shear-thinning non-Newtonian fluid in which the viscosity reduces with the shear rate. When simulating arterial flow, it is well established that the non-Newtonian nature is important in the smallest vessels; however, there is no consistent view as to whether it is required in larger arteries, such as the carotid. Here, we investigate the importance of incorporating a non-Newtonian model when applying a plaque deposition model which is based on near-wall local haemodynamic markers: the time-averaged near wall velocity and the ratio of the oscillatory shear index to the wall shear stress. In both cases the plaque deposition was similar between the Newtonian and non-Newtonian simulations, with the observed differences being no more significant than the differences between the selected markers. More significant differences were observed in the haemodynamic properties in the stenosed region, the most significant being that lower levels of near-wall reverse flow were observed for a non-Newtonian fluid.
