Post-storage changes of volatile compounds in air-and sun-dried raisins with different packaging materials using HS-SPME with GC/MS.
Free- and bound-form volatiles in sun-dried raisins (SDRs) and air-dried raisins (ADRs) of 'Thompson Seedless' were analyzed by gas chromatography-mass spectrometry (GC/MS) for 0, 3, 6, 9 and 12 months of storage. The compounds originating from glycosidically bound (GB) volatiles were significantly more abundant in bound-form than their free-form. A total of 89 and 88 free-form compounds were identified in […]
EXPRESS: Use of Visible–Near-Infrared (Vis–NIR) Spectroscopy to Detect Aflatoxin B1 on Peanut Kernels.
Current methods for detecting aflatoxin contamination of agricultural and food commodities are generally based on wet chemical analyses, which are time-consuming, destructive to test samples, and require skilled personnel to perform, making them impossible for large-scale nondestructive screening and on-site detection. In this study, we utilized visible-near-infrared (Vis-NIR) spectroscopy over the spectral range of 400-2500 nm […]
Binding of peanut allergen Ara h 2 with Vaccinium fruit polyphenols.
The potential for 42 different polyphenols found in Vaccinium fruits to bind to peanut allergen Ara h 2 and inhibit IgE binding epitopes was investigated using cheminformatics techniques. Out of 12 predicted binders, delphinidin-3-glucoside, cyanidin-3-glucoside, procyanidin C1, and chlorogenic acid were further evaluated in vitro. Circular dichroism, UV-Vis spectroscopy, and immunoblotting determined their capacity to (i) bind […]
Genetic diversity, antimicrobial resistance and virulence profile of Salmonella isolated from the peanut supply chain.
Thirty-Eight Salmonella isolates recovered from different stages of the peanut supply chain in three Brazilian States (São Paulo, Minas Gerais and Bahia) were subtyped by pulsed-field gel electrophoresis (PFGE) and characterized by phenotypic and genotypic tests for antimicrobial resistance and virulence genes. The isolates were distributed into seven PFGE pulsotypes. All the isolates were resistant to sulfonamide. […]
