  Agaricus bisporus (A. bisporus) is highly susceptible to postharvest quality deterioration, including enzymatic browning, cap opening, water loss, and tissue softening. Carbon dioxide (CO2) modified atmosphere packaging ...

• Transcriptomics reveals the mechanism by which UV-B radiation delays postharvest browning of Agaricus bisporus by maintaining cell membrane stability 

  Bai, Shiqi; Tong, Wenying; Shang, Xueli; Mariga, Alfred Mugambi; Ma, Ning; Fang, Donglu; Yang, Wenjian; Hu, Qiuhui; Pei, Fei (Elsevier, 2026-01)

  Maintaining cell membrane homeostasis is crucial for suppressing postharvest browning in Agaricus bisporus (A.bisporus). This study utilized transcriptomics to investigate the effects of 50 kJ m⁻² ultraviolet B (UV-B) ...

• Layer-by-layer assembly sodium hyaluronate/ε-polylysine-coated Zein nanoparticles enhance the gastrointestinal delivery and anti-inflammatory activity of capsaicinoids 

  Yang, Qin; Li, Yike; Zuo, Xiao; Mariga, Alfred Mugambi; Hu, Qiuhui; Yang, Wenjian; Zhang, Fenglun; Xie, Minhao; Liu, Jianhui; Pei, Fei (Elsevier, 2026-06)

  In our previous study, capsaicinoids (CAP) were successfully isolated from the placenta of chili peppers. However, their poor water solubility limited their application. Therefore, this study aims to prepare hyaluronate ...
