“…In general, the foamability of SPI increases with increasing temperature (He et al, 2015), the denaturation temperature of 7S globulin is reported to be 70 °C, and the denaturation temperature of 11S globulin is 90 °C (Zhang et al, 2004). Rickert et al (2004) showed that the surface tension and foaming performance of unheated 7S and 11S were lower, but after heat treatment, the foaming performance of 7S and 11S was significantly improved, owing to the surface of the air-water interface, the tension decreased with increasing temperature, which is more conducive to the formation of foam (Critello et al, 2020). Berli et al (1999) showed that when the heating temperature exceeds 70 °C, globulin aggregates to form large-particle micelles, and the foamability decreases with the decrease of surface hydrophobicity.…”

“…At this time, the foam volume reaches the maximum. During the formation of the foam, the number of bubbles gradually increases from large to small, and finally loss of liquidity (Critello et al ., 2020). Because of its amphiphilic group, SPI is used as a surfactant (Raikos et al ., 2007).…”

Soy protein isolate (SPI) is widely used as a foaming agent due to its rich nutritional value and low price. Foaming is one of the key processing characteristics in food processing and is generally used in foam-type foods. It plays an essential role in the flavour quality and appearance characteristics of food. Generally speaking, the foaming activity and foaming stability of regular SPI are not sufficient enough to meet the needs of practical applications. There is an urgent need to solve this drawback and improve the status quo of the food processing industry. The current research on the foaming properties of SPI across the globe focuses on improving foaming characteristics through optimising influencing factors and the use of different modification methods. Hence, this review aims to sort out the scientific research on the foaming mechanism of SPI and summarises evaluation methods, influencing factors and modification methods to improve the foamability of SPI to explore more applications of SPI. It will provide a theoretical basis for the production of SPI natural green active agents with good performance.

“…From a pharmacological point of view, it is important that they offer pharmacotherapeutic action, even at low concentrations [ 7 ]. The delivery method has to guarantee high levels of sterility (introducing the molecule of interest into the body in a controlled manner) and safety (procedure performed under controlled conditions) [ 8 , 9 , 10 ].…”

FT-IR Analysis of Structural Changes in Ketoprofen Lysine Salt and KiOil Caused by a Pulsed Magnetic Field

High-intensity, low-frequency magnetic fields (MFs) have been widely used in the treatment of diseases and in drug delivery, even though they could induce structural changes in pharmacological molecules. Morphological changes in ketoprofen and KiOil were investigated through Fourier-transform infrared spectroscopy (FT-IR). Unsupervised principal component analysis was carried out for data clustering. Clinical validation on 22 patients with lower back pain was managed using diamagnetic therapy plus topical ketoprofen or KiOil. The Numerical Rating Scale (NRS) and Short-Form Health Survey 36 (SF-36) were used to evaluate clinical and functional response. Ketoprofen showed clear clustering among samples exposed to MF (4000–650 cm−1), and in the narrow frequency band (1675–1475 cm−1), results evidenced structural changes which involved other excipients than ketoprofen. KiOil has evidenced structural modifications in the subcomponents of the formulation. Clinical treatment with ketoprofen showed an average NRS of 7.77 ± 2.25 before and an average NRS of 2.45 ± 2.38 after MF treatment. There was a statistically significant reduction in NRS (p = 0.003) and in SF-36 (p < 0.005). Patients treated with KiOil showed an average NRS of 7.59 ± 2.49 before treatment and an average NRS of 1.90 ± 2.26 after treatment (p < 0.005). SF-36 showed statistical significance for all items except limitations due to emotional problems. A high-intensity pulsed magnetic field is an adjunct to topical treatment in patients with localized pain, and the effect of MF does not evidence significant effects on the molecules.

“…Critello et al found that foams can be produced using 4% polidocanol solutions and different power levels in the case of ultrasound technique, and the foams produced were similar to those produced by the commercially available Easyfoam ® kit. Moreover, ultrasound generated bubbles were more stable and less prone to ageing [ 27 ].…”

The use of high-frequency strain waves to perform examinations and note measurements is referred to as ultrasonic testing (UT). UT is commonly used for the detection or evaluation of flaws and characterization of materials, among other applications. A standard ultrasonic inspection system comprises a pulser/receiver, transducer, and display devices. The pulser/receiver produces electrical pulses of high voltage. The transducer generates high-frequency ultrasonic energy after being driven by the pulser. The reflected wave is then converted into an electrical signal by the transducer and is displayed on a screen. The reflected signal strength versus the time plot helps to glean information regarding the features of a defect. In this paper, we discuss the experiments performed in a laboratory setting to determine ultrasound-based biofilm sensor sensitivity in relation to changes in the surrounding environment of temperature, concentration, turbidity, and conductivity of the liquid passing through the system. The effect of the change in frequency of the sensors was also studied. The sensors being developed are small and compact, portable, can be placed on the outer walls of the desired surface, use digital signal processing techniques, and the biofilm presence on the inner walls of the surface can be monitored.
