Summary: Biogenic amines (BA) are molecules with biological functions that can accumulate at toxic concentrations in foods. Some microorganisms have been identified as responsible for their accumulation. Histamine, tyramine, and putrescine are the most commonly found BA at highest concentrations. Ingesting food with high BA concentrations can lead to intoxication. Additionally, there is synergy between different BA, emphasizing the need for regulation to protect consumer health.

Summary: Factors affecting the composition, texture properties, nutritional value, and shelf life of tofu include coagulant type, concentration, interactions, freezing, pH, lipid oxidation, biogenic amines, and other factors. Researchers are exploring emerging thermal and non-thermal technologies as alternatives to traditional methods to improve the characteristics, shelf life, and nutritional value of tofu. Non-thermal methods such as cold atmospheric pressure plasma, pressure activated water, high intensity ultrasound, and high hydrostatic pressure have shown potential for improving tofu quality and safety, but further research is needed to understand the mechanisms and impacts of these techniques.

Summary: A functionalized mesoporous silica-coated solid-phase microextraction (SPME) Arrow system was developed for the enrichment of six biogenic amines (BAs) from pork and fish samples. MCM-41 was used as the substrate material and functionalized to adjust its surface acidity and hydrophobicity. The functionalized MCM-41 was coated on a bare SPME Arrow and showed higher affinity and reduced interference compared to a commercial SPME Arrow.

Summary: Data encryption aims to protect data confidentiality during storage, transmission, and processing, but it may not always be the best choice as attackers can exploit weaknesses in encryption algorithms for decryption. Users of proprietary applications are vulnerable to security and privacy threats due to reliance on vendor security measures. Covert communication techniques achieve security through hidden communication channels and have seen significant advancements, but existing literature does not cover all aspects comprehensively.

Summary: In this study, histamine in tuna fish samples was measured using ultra-performance liquid chromatography with a phenyl isothiocyanate derivative. The experiment was designed and investigated using Minitab software, including screening and optimization steps. The effective parameters, such as triethylamine volume, phenyl isothiocyanate volume, reaction temperature, reaction time, and mobile phase pH, were examined in the screening step. The calibration curve for histamine derivatized was then drawn, with a correlation coefficient of 0.994. The method detection limit was 0.36 μg/mL and the limit of quantification was 1.19 μg/mL. The method showed a relative standard deviation between 1.06% and 2.21% for concentrations of 1.0-100.0 μg/mL, with a recovery method ranging from 90.8% to 103.1% for measuring histamine derivatized in real fish samples.
