“…UV spectroscopy has been widely applied to characterize the interaction between polyphenols and macromolecules ( Lei et al, 2022 ). In Li's study, the soluble dietary fiber in lotus root successfully adsorbed gallic acid (GA) and catechin (CC), respectively, which was determined via UV and FT-IR spectra (S.

“…One of the most notable findings on both scales is the absence of calcium phosphate (CaP) deposits that are thought to be the predominant fouling species at UHT temperatures. 33−35 If calcium phosphate deposits are present in these fouling layers at concentrations similar to proteins, the Raman peak intensities should be much greater than those seen for proteins due to the prominent vibrational modes of PO 4 3− in crystalline CaP species, which have very sharp, identifiable peaks, especially that of ν 1 PO 4 that occurs around ∼960 cm −1 . 36,37 There are several explanations for the absence of CaP deposits in these foulants.…”

“…Rigid or Sauerbrey films are characterized by negligible dissipation, while soft deposits (i.e., laterally homogeneous) or discrete particles (i.e., laterally heterogeneous) are characterized by nonnegligible dissipation and/or overtone-dependent responses. 1 As a precise technique for studying surface interactions, QCM-D is a versatile technology as demonstrated by a wide range of recent applications, including pigment stabilization, 2 saliva interactions with hydrophobic surfaces, 3 protein complexation with polysaccharides and polyphenols, 4 and the detection of residual pesticides 5 and antibiotics in foods. 6 With specific focus on fouling, recent applications of QCM-D include fouling of reactor walls during emulsion polymerization, 7,8 membrane fouling by thermomechanical pulping process water, 9,10 and monitoring of cleaning after fouling using an in-line QCM sensor.…”

The thermal processing of milk is negatively impacted by fouling, which decreases the rate of heat transfer and increases the frequency of cleaning. Small-scale tools that can predict fouling on larger scales are crucial to understanding and mitigating fouling. In this work, milk fouling is compared between the submicron scale, using a high-pressure high-temperature quartz crystal microbalance with dissipation (HPHT QCM-D), and the pilot scale. Fouling rates are monitored in situ and foulants are characterized ex situ using Raman spectroscopy and atomic force microscopy (AFM). The results reveal that a proteinaceous foulant is formed on both scales. Also, a gradient in the magnitude of fouling is observed at both scales as a function of the local residence time and temperature with the greatest amount of fouling observed for the smallest local residence time and at the highest temperature (132 °C). The results suggest a scale-up factor of approximately 70−120 times when converting between QCM-D and pilot-scale fouling thicknesses. Similarities in the foulant properties and fouling rates support QCM-D as a viable technology for scale-up studies of milk fouling.

“…Tea contains a great variety of bioactive compounds, such as polyphenols, polysaccharides, alkaloids, free amino acids, aromas, and saponins. Recent studies have shown that water-soluble tea polysaccharides possess many bioactive effects, such as antioxidant [ 1 , 2 ], anti-inflammatory [ 3 ], anti-cancer [ 4 , 5 ], and anti-sepsis effects [ 6 ]. They can also lower blood glucose [ 7 , 8 , 9 ] and they have immune-regulatory [ 10 ] functions.…”

Pulsed electric fields (PEF) and ultrasonic-assisted extraction (UE) were applied to improve the extraction performance of selenium-enriched tea polysaccharides (Se−TPSs) in mild conditions. Two combined extraction processes were investigated: (1) PEF strength at 10 kV/cm followed by conventional extraction (CE) at 50 °C for 60 min and (2) PEF+UE (PEF strength at 10 kV/cm followed by UE at 400 W for 60 min). The optimal extraction yields, and energy consumption rates were obtained at 36.86% and 41.53% and 78.78 kJ/mg and 133.91 kJ/mg, respectively. The Se−TPSs were analyzed and characterized by GPC, UV, and FT-IR, which evidenced the structural stability of the Se−TPSs during the extraction processes. It was found that PEF and UE could reduce the particle size diameter of the Se−TPS extract, as well as the proportion of uronic acid. Moreover, PEF could increase the selenium content in the Se−TPS extract by 160.14% due to a lower extraction temperature compared to conventional extraction. The antioxidant activities of the Se−TPSs in vitro were investigated using OH, O2−, and ABTS+ scavenging experiments, as well as a total antioxidant ability evaluation. It was found that the antioxidant activity of the Se−TPSs obtained using PEF2+CE2 was relatively high due to the potential synergistic effect between the selenium and polysaccharides. Based on these results, we speculate that PEF2+CE2 was the best extraction process for the Se−TPSs. Furthermore, this research indicates the application of selenium-enriched tea for functional food production.
