“…Similar findings were acknowledged by Bansal et al., [ 53 ] who identified a similar food powder coefficient pattern for PFSD. Similar studies [ 60–62 ] reported that, rise in electrostatic forces or cohesiveness values around 1 in different starch powder samples signifies better stability during transportation.…”

The Chenopodium album starch is isolated and further modified by using different octenyl succinic anhydride (OSA) concentrations (1%, 2%, 3%) in slightly acidic and alkaline conditions (pH = 5, 6, 8, 9). The modification of starch significantly reduces amylose content as well as functional properties viz. solubility, swelling power, water, and oil absorption capacity. The higher compressibility is found in native starch (35.32%) as compared to modified starch (17.42% at pH 9) as elucidated from Carr's index indicating very poor and fair relative flowability, respectively. The decline in the cohesive nature of native starch is also detected from the reduced caking strength (1072.03 to 367.23 g mm) and cohesion index (15.37 to 11.37 mm) after modification. Modified starch also reflects a rise in pasting temperature from 80.05 to 87.10°C. SEM images and X‐ray diffraction reveals the development of regular‐shaped and larger starch particles and an increase in peak intensity. Overall, the present findings confirm that OSA treatment significantly increases the flowability to fair flow compared to native starch's cohesive nature.

“…Ultrasound probes have demonstrated advantages over ultrasound baths, mainly because the former concentrate their energy on a localized sample zone, thus providing more efficient cavitation in the liquid (Bui et al, 2021). Therefore, if a system is subjected to high shear rates, the mechanical energy supplied can lead to a more unstable condition, promoting coalescence (Mercan et al, 2018).…”

“…The energy supplied was probably sufficient to promote fat droplet breakdown (Oliveira et al, 2017) and form new droplets with smaller diameters, making the systems less polydisperse. However, the Uturrax technique exhibited a slight increase in fat retention at 24000 rpm/min because the system was exposed to high homogenization speeds (Mercan et al, 2018), which may promote elevated shear rates responsible for not only breaking the droplets but also for favoring coalescence. The interactions among fat droplets, along with the action of proteins as surfactants and the excess Gibbs-free energy on the surface, are factors that can negatively influence the disruption of fat globules in aqueous dispersions.…”

“…UTurrax, Mprocessor, and Oshaker work at different mechanical shear values. For example, in a high-pressure homogenizer (HPH), homogenization occurs when the liquid subjected to a pressure difference flows through a small orifice (Mercan, 2018). On the other hand, cavitation, caused by ultrasonic waves, is the phenomenon responsible for promoting homogenization in Ubath and Uprobe (Calvo et al, 2018).…”

Background: The retention of human milk nutrients in gastric tubes used to feed premature infants is a challenge to be overcome. Research Aims: To evaluate (1) the performance of six homogenizers (mixing processor, piston valve, ultrasonic bath, ultraturrax, stirring mixer, and ultrasound probe) for the fat retention reduction in gastric tubes; (2) the influence of the best homogenization conditions on the fatty acid and protein profiles of human milk; and (3) the cost/benefit ratio for the inclusion of homogenization as a new step in human milk processing. Methods: The influence of different levels and times of homogenization on reducing fat retention of human milk in probes was evaluated in this comparative prospective cross-sectional study. After homogenization, human milk flowed through a gavage and infusion pump apparatus used for feeding. Fat content was quantified before and after feeding. The techniques that reduced fat globule sizes and/or promoted a lower percentage of fat holding were evaluated for efficiency, variations in the fatty acid and protein profiles, and energy density and operating costs. Results: Homogenization led to a reduction in fat retention in feeding probes. The mixer processor and the ultrasound probe reduced fat retention by 99.23% (SD = 0.07) and 99.95% (SD = 0.02), respectively, and did not negatively influence fatty acid and protein profiles. The mixer processor demonstrated low energy density and low cost for human milk processing. Conclusion: Homogenization promoted reduced fat retention in the feed probe and could help maintain fat nutrients of human milk during enteral feeding.

“…In recent years, HPH treatment has been used to improve the flow and rheological properties of liquid materials during mixing and flow through production. For example, HPH treatment reduced the cohesion and caking performance and improve the powder fluidity of skim milk powder (Emin Mercana, 2018). HPH treatment increased the apparent viscosity and dynamic modulus of beet pulp powder suspensions (Huang, Liu, Yang, & He, 2020).…”

The effects of superfine grinding on the properties of chrysanthemum powder (CP) and high pressure homogenization (HPH) on the rheological properties of CP suspensions were investigated. Superfine grinding reduced particle size to a D 50 of 28.45 μm. Instantaneous flow function and wall friction tests demonstrated that superfine ground CP had poor flowability and was more cohesive than more coarsely ground samples. Superfine grinding increased thermal stability and reduced the crystallinity of CP. After HPH treatment, the apparent viscosity and consistency coefficient (k, from 0.027 ± 0.005 to 1.847 ± 0.472) of CP suspension was significantly improved (p <.05), indicating that HPH treatment increased the consistency and reduced the fluidity of CP suspensions. As the HPH pressure increased from 40 to 120 MPa, the storage modulus (G') and loss modulus (G") of the CP suspensions increased, which fitted well with the Power Law model (R 2 >.961). The CP suspension is a non-Newtonian fluid with shear thinning behavior. Flow and rheological characteristics are measured under different consolidation pressures and HPH pressures, respectively. These findings reveal the potential application of superfine grinding and high pressure homogenization in the development of CP.
