Consumers around the world prefer high quality table grapes. To achieve higher quality traits at ripening, grapevine producers apply different plant growth regulators. The synthetic cytokinin forchlorfenuron N–(2–chloro–4–pyridinyl)–N′–phenylurea (CPPU) is widely used, its effect on grape quality is poorly understood. We hypothesized that the use of CPPU in pre-flowering can lead to changes in the

Insight into the protein oxidation impact on the surface properties of myofibrillar proteins from bighead carp Food Chem. (IF 9.231) Pub Date : 2023-01-19 Yueyue Liu, Elliot Mubango, Peipei Dou, Yulong Bao, Yuqing Tan, Yongkang Luo, Xingmin Li, Hui Hong
The objective of this study was to elucidate the influence of oxidative modifications of myofibrillar proteins (MPs) on their surface properties. Oxidative modifications (deamination, formation of disulfide bonds and Schiff bases), particle size, net surface charge, and binding ability of volatiles (2-enthylfuran, 1-octen-3-ol, hexanal, and octanal) of oxidized MPs was measured. Molecular docking of

Effects of high-voltage electrostatic field (HVEF) on frozen shrimp (Solenocera melantho) based on UPLC-MS untargeted metabolism Food Chem. (IF 9.231) Pub Date : 2023-01-18 Jiao Liu, Feixia Zhu, Jing Yang, Yue Wang, Xiaohan Ma, Yongjiang Lou, Yongyong Li
Shrimp meat is prone to autolysis and decay due to the abundance of endogenous enzymes and contamination from microorganisms. HVEF freezing can slow the spoilage of shrimp, producing small and uniform ice crystals, resulting in less damage to muscle tissue. In this study, HVEF technique was used to freeze the shrimp (Solenocera melantho), and the UPLC-MS metabolic technique was used to investigate
