Compared with natural β-lactoglobulin, FBS was always positively charged, increasing to 9.69 mV when heated for 10 h, whereas WBS was always negatively charged, decreasing to −20.73 mV when heated for 20 min. Electrostatic interactions play a crucial role in the formation of both FBS and WBS. The free sulfhydryl content decreased by 10.4% at 20 min of heating compared with that at 1 min of heating. β-Lactoglobulin converted the exposed free sulfhydryl groups to disulfide bonds when heated under neutral conditions, and disulfide bonds played a key role in the formation of WBS. The surface hydrophobicity of FBS reached its maximum at 1 h of heating, while that of WBS reached its maximum at 15 min of heating.

The results demonstrated that the antioxidant activities of sesame oil extracts varied significantly among OEMs, and the ethanol extract of solvent extraction-ethanol (SEE) sesame oils possessed the highest inhibition rates of DPPH⁻ (2,2′-diphenyl-1-picrylhydrazyl radical; 67.07 ± 0.78%) and ABTS⁺ (2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt; 18.64 ± 1.34%), and the highest antioxidant ability to H₂O₂-induced HepG2 cells.

This study investigated prospective use of onion peel extract as a PS in combination with 405 nm blue light for the inactivation of <i>Salmonella</i> Typhimurium, a common foodborne pathogen on eggs. Extracts were obtained using 99% ethanol, 50% ethanol, and distilled water (DW). Their photosensitizing activities were then compared. The combination of 405 nm blue light and onion peel extract using 99% ethanol reduced bacterial populations more effectively than blue light treatment alone, while also increasing reactive oxygen species generation, cell membrane permeability, lipid peroxidation, and DNA damage levels. However, the antimicrobial effect of the 99% ethanol extract did not show a concentration dependence. Spraying DW extract on eggshell treated with 99% ethanol onion peel extract at 1 mg/mL and blue light further enhanced <i>Salmonella</i> reduction. Liquid chromatography was conducted for component separation. However, none of the separated fractions exhibited a significant antibacterial effect, suggesting that the active compounds responsible for antibacterial activity might work synergistically in the crude extract rather than individually.

The solutions were characterized, and their antioxidant activities were compared to identify the most stable and effective formulation for preserving fresh-cut bitter bamboo shoots. The results revealed that the synthesized selenium nanoparticles were spherical, with an average diameter of 86.96 nm and a <i>ζ</i>-potential of −3.81 mV.
