Summary: Aflatoxins are highly toxic secondary metabolites of fungi that are classified as poisonous mycotoxins. They are mainly produced by Aspergillus flavus and Aspergillus parasiticus in cereals, peanuts, and animal feeds. Sample preparation techniques, chromatographic methods, and detection techniques are crucial in aflatoxin analysis. Selectivity in analysis is achieved using bio-recognition elements like enzymes, antibodies, or DNA sequences. Determination of aflatoxins is essential for food safety due to their high toxicity and presence in food and agricultural products. The choice of analysis method depends on the sample nature, available equipment, toxin concentration range, sensitivity, detection limit, precision, selectivity, required analysis time, and personnel training.

Summary: Berberine was extracted from Berberis vulgaris, Berberis aquifolium, and Hydrastis canadensis using ethanol and water (70:30, v/v). The extracted berberine was characterized using UV-visible and Fourier-transform infrared spectroscopy. Thin-layer chromatography and high-performance liquid chromatography (HPLC) methods were both employed for the separation and identification of berberine, and showed different applications. The extracted berberine exhibited better activity in treating Leishmaniosis compared to the standard drug Amphotericin B.

Summary: A novel fluorine-functionalized triazine-based porous organic polymer (F-POP) was developed for the adsorption of aflatoxins. The F-POP demonstrated superior adsorption ability due to multiple interaction mechanisms, including hydrogen bond, F-O interaction, pi-pi interaction, F-pi interaction, and hydrophobic interaction. Furthermore, magnetic F-POP was prepared and used as a magnetic sorbent for the extraction of trace aflatoxins in peanut and rice samples.

Summary: Cherry wines enriched with green tea infusion showed increased total polyphenol content and antioxidant activity. However, these properties were reduced after in vitro digestion. The wines also exhibited an inhibitory effect on intestinal microflora growth, with E.coli being the most sensitive microorganism. The bioactive compounds derived from green tea also increased the potential of alpha-glucosidase inhibition. These wines could be a promising alternative for diabetes therapy.

Summary: This study investigated the effects of different drying processes and times on phenolic compounds and antioxidant activities of mangosteen pericarps (MP). Results showed that freeze-drying for 36 and 48 hours resulted in higher total anthocyanin content, while the 36-hour freeze-drying process exhibited higher total phenolic content, total flavonoid content, and reducing power. Therefore, the 36-hour freeze-drying process is a more efficient and energy-saving method for industrial applications, and the dried MP extracts could be used as an alternative to synthetic food colorants.

Summary: This study evaluated the functional and volatile compounds in the extracts of MD pineapple peel and core. The results showed that the peel had lower total soluble solids, pH, titratable acidity, sweetness index, and astringency index compared to the core. The peel also had higher total phenolic and flavonoid contents, better antioxidant activity, and a higher concentration of certain volatile compounds. These findings provide important insights into the valorization of MD pineapple waste.

Summary: Consumers are interested in products that have health benefits, and milk stability and integrity are key factors in dairy product quality. Milk contains nutrients that have various physiological functions in the human body. The effects of pulsed electric fields (PEF) on milk have been extensively studied, mainly focused on inactivating microbes and enzymes for preservation purposes. However, the impact of PEF on milk macro- and micronutrients is not well understood and is important for the functionality and stability of milk and dairy products. This review provides detailed information on PEF, its inactivation mechanism, and its effects on milk nutrients. It also discusses the limitations and future prospects of commercializing and implementing PEF in the food industry.
