Naked-eye monitoring of pasteurized milk freshness via highly stable, pH-responsive resazurin/cationic guar gum/κ-carrageenan intelligent labels

Progressive acidification during pasteurized milk spoilage provides a chemical signal for visual freshness assessment. Here, we developed a pH-responsive colorimetric label by confining resazurin (Res) within a cationic guar gum/κ-carrageenan (CGG–CAR) polyelectrolyte network. No...

Dose-Dependent Preservation of Highland Barley Flour Storage Quality by Lycium barbarum Polysaccharide: Evidence from 240-Day Storage Monitoring and Untargeted Lipidomics

Highland barley (hulless barley, Hordeum vulgare L. var. nudum) flour is a nutritionally dense staple of the Qinghai–Tibet Plateau, but its high contents of unsaturated lipids and active endogenous enzymes render it highly susceptible to storage deterioration. Natural polysacchar...

Plant growth regulator diethyl aminoethyl hexanoate suppresses Aspergillus flavus growth and aflatoxin biosynthesis through disruption of redox homeostasis

ABSTRACT Aflatoxin B₁ (AFB₁), produced by Aspergillus flavus , is a major threat to food safety and human health. In this study, we report that diethyl aminoethyl hexanoate (DA-6), a plant growth regulator, exhibits strong antifungal and anti-aflatoxigenic activities against A. f...

Expression and immunoassay application of full-length recombinant antibody recognizing chlorantraniliprole using Pichia pastoris expression system

Abstract Full-length recombinant antibodies (rAbs) expressed in yeast offer the advantage of a eukaryotic system ensuring proper folding and bioactivity, along with high yield and low cost. In this study, plasmids encoding the light chain and heavy chain of the anti-chlorantranil...
