To enhance the emulsion stability of RBP, mixed solution epigallocatechin-3-gallate (EGCG) and rice bran protein (RBP) was pretreated by increasing ultrasonic power (200-500 W). Ultrasonic pretreatment decreased α-helix/β-sheet ratio (P < 0.05), caused red-shift absorption peaks intrinsic fluorescence UV spectroscopy EGCG-RBP complex. With power, combined phenol content, particle size, absolute value ζ-potential, free -SH surface hydrophobicity complex initially rose, subsequently dropped...

To explore the effects of rice bran endogenous phenolics on protein under rancidity-induced oxidation, structure non-dephenolized and dephenolized with different degrees rancidity (rice was stored for 0, 1, 3, 5, 10 d) were investigated. During storage, dephenolization increased carbonyl (from 5.32-24.59 to 6.11–26.52 μmol/g) free sulfhydryl 24.41-32.33 32.64–45.04 contents protein, decreased disulfide bonds content 24.26-26.61 21.78–25.42 μmol/g). Meanwhile, improved secondary structural...

To improve the application of insoluble protein-polysaccharide-phenol natural complex particles as Pickering emulsion stabilizers within food industry, rice bran (IRBPPP) was modified using epigallocatechin-3-gallate (EGCG) under alkaline conditions. The addition EGCG increased bound phenol content and soluble protein IRBPPP, decreased free amino content, ζ-potential, surface hydrophobicity, contact angle IRBPPP. moderate (12.5-25 mg/g) enhanced flexibility in IRBPPP (α-helix/β-sheet from...

Classical swine fever virus (CSFV) has a tropism for vascular endothelial cells and immune system cells. The process release of pro-inflammatory cytokines, including IL-1β IL-18, is one the fundamental reactions innate response to viral infection. In this study, we investigated production from macrophages following CSFV Our results showed that was upregulated after infection through activating caspase-1. Subsequent studies demonstrated reactive oxygen species may not be involved in...

Classical swine fever is one of the most important diseases worldwide and has tremendous socioeconomic impact. In this study, we focused on signalling pathways Toll-like receptors (TLRs) because their roles in detection response to viral infections. To end, two classical virus (CSFV) strains, namely highly virulent CSFV Shimen strain avirulent C (a vaccine strain), were employed, expression 19 immune effector genes was analysed by real-time PCR, Western blot analyses, ELISA flow cytometry...

A water soluble branched cationic polyacrylamide (BCPAM) was synthesized using solution polymerization. The polymerization initiated potassium diperiodatocuprate, K 5 [Cu(HIO 6 ) 2 ](Cu(III)), initiating the self-condensing vinyl copolymerization of acrylamide and acryloxyethyltrimethyl ammonium chloride (DAC) monomer. resulting copolymer characterized by use Fourier-transform infrared (FTIR) spectroscopy nuclear magnetic resonance (NMR) spectroscopy. Its flocculation properties were...
