Products with a Protected Denomination of Origin (PDO) are vulnerable to misdescription of their true geographical origin. In this work a method has been developed that allows the authentication of La Vera paprika powder (Pimentón de la Vera), a PDO product from the central-west Spanish region, Extremadura. The mass fractions of Br, Ca, Cr, Cl, Cu, Fe, K, Mn, Ni, P, Rb, S, Sr and Zn determined by energy dispersive X-ray fluorescence (ED-XRF) are used for classification purposes by multivariate analysis using Soft Independent Modelling of Class Analogy (SIMCA) (PCA-Class) and Partial Least Square-Discriminant Analysis (PLS-DA). Sixty-seven paprika samples purchased in supermarkets around Europe and on-line via the official web-site of Pimentón de La Vera, were used to build up the models for prediction purposes. The PCA-class model of La Vera paprika powder had a sensitivity of 82%, a specificity of 100% and an accuracy of 91%, whereas the PLS-DA model had a sensitivity of 100%, a specificity of 91% and an accuracy of 96%.

Background: The 11+Myco MS-PREP® Immunoaffinity Column (IAC) contains a gel suspension of monoclonal antibodies specific to the toxins of interest. Following sample extraction, the IAC is used for cleanup and concentration of mycotoxins prior to analysis by Liquid Chromatography with Tandem Mass Spectrometry (LC-MS/MS).
Objective: This study evaluated the IAC with LC-MS/MS method for Performance Tested Methods SM certification for simultaneous determination and confirmation of Aflatoxins B1, B2, G1, G2, and M1; Deoxynivalenol, Fumonisins B1, B2, and B3; Ochratoxin A; T-2; HT-2; and Zearalenone from corn, wheat, cereal-based baby food (with and without dairy ingredients), paprika, chili powder and animal feed.
Exploring the Metabolome and Antimicrobial Properties of L. (Baklouti and Paprika) Dried Powders from Tunisia.

In this study, for the first time, the volatile fraction from two domesticated accessions ("Paprika" and "Baklouti") collected in Tunisia was investigated by two complementary analytical techniques, such as Solid-Phase Microextraction-Gas Chromatography/Mass Spectrometry (SPME-GC/MS) and Proton Transfer Reaction-Time-of-Flight-Mass Spectrometry (PTR-ToF-MS). The obtained results highlighted the presence of a high number of Volatile Organic Compounds (VOCs), including monoterpene and sesquiterpene compounds with -curcumene, I-zingiberene, -bisabolene and -sesquiphellandrene as the major components. In addition, GC/MS was used to investigate the non-volatile chemical composition of the dried powders and their extracts, which were found to be rich in sulfur compounds, fatty acids and sugars.

Article Synopsis
- Korean landrace red peppers, particularly the Subicho variety, are vital in Korean cuisine but are vulnerable to biotic stresses, affecting their quality and yield.
- Using NMR spectroscopy and multivariate analysis, researchers identified 42 metabolites with significant differences between healthy and stressed Subicho peppers, noting lower sucrose and higher amino acid levels in stressed samples.
- The study highlights unique metabolic adaptations in Subicho peppers that suggest resilience to stress, providing insights for targeted breeding programs to improve quality and economic viability in the food industry.

Antioxidant activity of freeze-dried paprika powder and storage properties of emulsion-type pork sausages containing diverse concentrations of this powder (0%, 1%, 2%, and 3%) were analyzed. Antioxidant activities of red and yellow paprika powders were analyzed by evaluating their 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, ferric reducing antioxidant power (FRAP), total phenol content (TPC), and total flavonoid content (TFC). The yellow paprika powder exhibited remarkably higher DPPH radical scavenging activity, FRAP values, and TPC than the red paprika powder (p<0.

In order to understand the status of aflatoxin contamination in dried chilli products in Gansu Province and the risk of dietary exposure, a total of 106 samples of dried chilli products from farmers' markets and supermarkets in 14 prefecture-cities of Gansu Province were collected and analysed by isotope dilution liquid chromatography-tandem mass spectrometry. The results showed that the detection rate of aflatoxin in dried chilli products in Gansu Province was 30.2%, and the average level was 1.
