Summary: Two novel microwave-assisted extraction methods were developed for isolating phenols and tocopherols from pistachio nuts. The extracts were analyzed using RP-HPLC-UV, and thirteen phenolic compounds as well as alpha, beta + gamma, and delta tocopherols were identified. The analytical methods showed good linearity and high recovery rates. Principal component analysis and agglomerative hierarchical clustering were used to analyze differences in the compounds' concentrations and to cluster the samples based on their geographical origin.

Summary: Cocoa beans are an important source of polyphenols, but the content of these compounds can be reduced by post-harvest processes, such as drying. This study optimized the extraction of procyanidins using Microwave-Assisted Extraction and evaluated the stability of catechins, procyanidins, and theobromine at different drying temperatures. The optimal extraction conditions were determined to be 67 degrees C, 56 min, and 73% methanol, while the maximum procyanidin content was obtained at 40 degrees C during drying. This study also evaluated the stability of various procyanidin dimers, trimers, and tetramers on drying temperature for the first time.

Summary: This study assessed the effectiveness of the adjuvant Dash (R) HC EC against garlic rust as well as the degradation and translocation of two fungicides, boscalid and pyraclostrobin, in plant tissues. It also validated an analytical method for determining the presence of these fungicides in garlic and garlic bulbs. Results showed that the adjuvant improved the efficacy and retention of the fungicides on garlic plants. Boscalid exhibited higher translocation from garlic leaves to garlic bulbs compared to pyraclostrobin. Based on a dietary risk assessment, the use of the adjuvant with boscalid and pyraclostrobin is considered safe 14 days after application.

Summary: Schiff base networks (SNWs) were used as a new coating for stir bars, and a method combining SNWs-coated stir bar sorptive extraction (SBSE) with high performance liquid chromatography-ultraviolet detector (HPLC-UV) was developed for the determination of pyrethroid pesticide residues in tobacco. The SNWs/PDMS stir bar showed high extraction efficiency for pyrethroid pesticides and good mechanical stability. Under optimized conditions, the method achieved low limits of detection and met the requirements for trace analysis of pesticide residues in the tobacco industry. The method was successfully applied to the analysis of pyrethroid pesticides in cigarette samples with satisfactory recovery rates.

Summary: A SPE-HPLC-DAD method was developed and validated to quantify SCFAs in chicken feces samples. The method utilized the STRATA(TM)-X-A 96 Well Plate SPE cartridge as the first step, with a gradient elution mobile phase and detection at 210 nm. The method showed linear relationships and high accuracy for acetic, propionic, and butyric acid. It is a simple, fast, linear, sensitive, accurate, precise, and robust method for SCFAs quantification.

Summary: This study investigated the effects of ultrasound-assisted (UAE), microwave-assisted (MAE), and ultrasound-microwave-assisted (UMAE) methods on pectin extraction from industrial tomato waste. The best extraction conditions were determined based on a fuzzy analytical method, considering pectin yield, galacturonic acid, and lycopene content. The results showed that UAE conditions with pH 1.5 and solid liquid (SL) ratio 1:30 resulted in high pectin yield and lycopene content. MAE conditions with 300 W power for 10 min yielded high pectin yield and galacturonic acid content. Moreover, the combination of UAE and MAE (UMAE) further improved the pectin yield compared to individual methods. However, the FTIR spectra of the obtained pectins showed similar structures regardless of the extraction technique.

Summary: Marine environment pollution has increased due to human activities, and macrophytes can be used as bioindicators to assess pollution levels in aquatic environments. The study investigated the anthropogenic pollution produced by eight organic UV filters in coastal macrophytes and found different detection frequencies for these pollutants in the samples. The highest concentration was detected in the seagrass species, Cymodocea nodosa, indicating potential chronic effects on seaweed and upper tropic levels.

Summary: Seafood, although beneficial for health, may pose potential risks due to the presence of chemical compounds such as HPVs. A study was conducted in Catalonia and the Canary Islands, Spain, to assess the occurrence of HPVs in commonly consumed seafood species and estimate the associated exposure and risk. Results showed higher levels of HPVs in Catalonia samples, with phthalate esters and benzenesulfonamides being the predominant compounds. Multivariate analysis revealed spatial differences in HPVs concentration profiles between Catalonia and the Canary Islands. Although exposures were higher in Catalonia, the intake of HPVs via seafood was not a major concern in either location.
