Seaweeds are a vital part of the human diet in many East-Asian and Pacific and have gained popularity in some European and South American countries, too. This can be attributed to their unique texture, taste, diverse nutritional profiles and nutraceutical properties. However, despite being a nutritious food, they contain anti-nutrients form insoluble complexes, bind essential minerals, and reduce their digestibility and availability Furthermore, the accumulation of heavy metals in seaweed poses health risks such as neurological, developmental, and organ damage. These components raise concerns about their overall nutritional value and safety. This review article discusses the presence of anti-nutrients and heavy metals in seaweed and their potential effects on human health. We also focus on possible pre-harvest practices and post-harvest processing techniques that can be used to reduce anti-nutrients and heavy metals for safer seaweed consumption. The findings underscore that with optimized cultivation and processing, seaweeds can be transformed into a safe, nutritious, and environmentally sustainable food source, contributing meaningfully to global food security and public health.

Sciadonic acid, or 20:3(5Z,11Z,14Z), is an unusual polyunsaturated fatty acid (PUFA) found in certain gymnosperm nuts and marine invertebrates. However, no study has detected it in commonly consumed food items. This study analyzed the fatty acid compositions of fresh, salted, and preserved duck eggs thoroughly via gas chromatography coupled with covalent adduct chemical ionization mass spectrometry (GC/CACI-MS). A multiple reaction monitoring method was developed to specifically characterize three 20:3 isomers found in duck eggs. Sciadonic acid was quantified at 0.13 % and 0.07 % (wt/wt of total fatty acids) in fresh and processed duck eggs, respectively. The major n-3 PUFA is DHA, with average concentrations of 1.44 %, 0.79 %, and 0.98 % in fresh, preserved, and salted duck eggs, respectively. For an average Chinese individual, the daily intake of DHA and total long-chain n-3 PUFA from all types of duck eggs is estimated to be 7.6 mg/day and 10.6 mg/day, respectively.

Microplastics (MPs) refer to microparticles and nanoparticles continuously released during the degradation of plastic waste and the use of plastic products. MP pollution in the environment is particularly persistent, particularly due to the stable and refractory nature of plastic waste. Compared with large plastic particles, MPs are more likely to spread through air, water, and other media, ultimately entering the human body through the food chain. Subsequently, MPs accumulate in a wide range of distributions throughout the body, including the gut, brain, immune system, and respiratory system, leading to chronic inflammation and disease, and even acting as vectors for other pathogens and contaminants that further compromise overall health. However, our understanding of the sources, distribution, detection methods, and human health impacts of MPs in food is limited. In this review, we provide an overview of the sources, environmental distribution, and potential health impacts of MPs in food (marine food, terrestrial food, water sources, and food materials and processing). We also examine strategies for controlling and reducing the accumulation of MPs in food. Finally, we highlight the challenges and prospects for future research. This review provides scientific evidence to support further studies on MPs in food.

Dairy products, particularly cheese, are prone to contamination by aflatoxin M1 (AFM1), a toxic compound generated by Aspergillus fungi. This study aims to determine the content of AFM1 in various types of cheese using high-performance liquid chromatography with fluorescence detection. Among the 109 cheese samples analyzed (probiotic, ripened in brine, pizza, UF, cream cheese, pasteurized white cheese, gouda, processed cheese, traditional, and mozzarella), 61.3 % were found to contain detectable levels of AFM1. There was a significant difference (p = 0.036) between cheese ripened in brine (0.05674 µg/kg) and traditional cheese (0.00169 µg/kg). A slight difference (p = 0.057) was observed between traditional cheese (0.00169 µg/kg) and white pasteurized cheese (0.05217 µg/kg). These findings emphasize the importance of ongoing monitoring and regulatory measures to mitigate AFM1 contamination in dairy products and ensure consumer safety.

In the present study, a rapid, efficient and environmentally friendly analytical approach was proposed for the determination of trace copper by flame atomic absorption spectrometry (FAAS) after spray-assisted fine droplet formation based liquid phase microextraction (SFDF-LPME), which eliminates the use of dispersing solvents. With the help of a simple nozzle apparatus, an efficient distribution of the extraction solvent into the sample was achieved. The developed SFDF-LPME-FAAS method achieved a limit of detection (LOD) of 1.6 µg L⁻¹ and a limit of quantification (LOQ) of 5.2 µg L⁻¹ under optimal conditions. A wide linear range was recorded with a regression coefficient (R²) of 0.9987 between 5.0 and 100 µg L⁻¹. The improvement in sensitivity was found to be 57.4-fold by comparing the slopes of the calibration plot equation of FAAS and SFDF-LPME-FAAS systems. The feasibility of the SFDF-LPME-FAAS method was evaluated by recovery studies using mate tea extracts and tap water samples. The good recovery results obtained for tap water samples and mate tea extracts in the range of 81.1 % - 113.8 % and 85.5 % - 120.8 %, respectively, showed that the method is applicable to similar matrices.

The impact of maturity on pear fruit quality directly affects consumer taste. Ultraperformance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was used to determine the sugar and organic acid components of mature pear fruits with different texture types, a texture analyzer was used to determine the texture traits of pear fruits. The result revealed that the variation tendency of sugar and organic acid components affected by the texture types, ripening stages and shelf-life. The decrease in flesh firmness of pear fruits was related to sucrose and glucose during the shelf-life of 0–14 days (d) at different ripening stages. According to the principal component analysis, Nanguoli, Jingbaili and Chili achieved the highest fruit quality score when harvested at 136 days after flower bloom (DAFB); Gute Luise and Korla pear achieved the highest fruit quality score when harvested at 146 DAFB; Yali and Dangshan Suli achieved the highest fruit quality score when harvested at 156 DAFB. In conclusion, combination of texture, sugar and organic acid components could serve as powerful maturity indicator candidates, provided valuable references for determining appropriate harvesting period and the best shelf-life quality of pear fruits.

The development of heavy metal-free preserved eggs (HMF-PE) has become a focal point of interest. Given the absence of plugging effect of heavy metals, the key in HMF-PE process is to quickly remove HMF-PE from the curing tank when the gel quality of its egg white (PEW) reaches peak to prevent "alkali injury". Our research confirms that the free alkalinity in the PEW conforms to a first-order kinetic model at 15, 20, and 25 ℃. Ultimately, based on the Gaussian equation, a predictive model for the comprehensive quality score of the PEW based on free alkalinity was constructed. Using this model to determine the optimal tank exit timing has resulted in a quality of HMF-PE that rivals commercial products, especially for those cured for 11 days at 25 ℃. This study establishes a theoretical foundation for the strategic harvesting of HMF-PE at the peak of their gel quality.

The introduction of genetically modified organisms (GMOs) to crops has rendered continuous concern and debates on GM foods, which led to the requirement of appropriate labelling of GMO-derived products and the demands of advanced technologies for on-site detection of transgenic crops. In this study, an electrochemical genosensor for rapid, ultrasensitive, and specific determination of cauliflower mosaic virus (CaMV35S) gene in GM soybean based on silica-gold nanoparticles composite electrode was developed. Colloidal gold nanoparticles were drop-coated onto a carbon screen-printed electrode (SPE) followed by amine-functionalized silica nanospheres to obtain a SiO₂-Au nanocomposite electrode (SiO₂-Au-SPE). Aminted DNA probes were grafted onto the SiO₂-Au-SPE using glutaric dialdehyde crosslinking agent. Meanwhile, thiolated DNA probes were directly chemisorbed onto the AuNPs-modified SPE for comparison purposes. Under optimum conditions, the DNA biosensor based on SiO₂-Au-SPE could determine the target CaMV35S gene in a linear DNA concentration range of 1.0 × 10⁻¹⁴ M to 1.0 × 10⁻⁸ M, with a limit of detection (LOD) of 2.37 fM cDNA. Glutaraldehyde crosslinking of aminated DNA probe to the aminated SiO₂ nanospheres attained stronger bonding strength with a 10-fold higher calibration sensitivity towards cDNA compared to direct chemisorption of thiolated DNA probe to the AuNPs by thiol chemistry. The validation study showed that the electrochemical DNA biosensor based on SiO₂-Au nanocomposite electrode was comparable to the conventional polymerase chain reaction (PCR) method for the evaluation of transgenic soybean contents in soy food samples, with 99.1–101.3 % recoveries of GM DNA.

γ-Glutamyl peptides rather than their α-isomers are a class of kokumi taste-active substances. The simultaneous determination of α- and γ-glutamyl peptides would be of great importance and could facilitate the flavor research in food science. Until now, LC/GC-MS method combined with chemical derivatization as well as CE-MS have been utilized to separate α- and γ- glutamyl peptides, but have shown the disadvantages of the inconvenience and the time-consuming. Here in this study, LC-MS/MS method with the isotope dilution assay was utilized to directly analyze α- and γ-glutamyl peptides in which γ-Glu-Cys-Gly(glutathione)-¹³C₂¹⁵N₁ was utilized as an internal standard. Taking six pairs of α- and γ-glutamyl peptides commonly existed in meat as the research models, the baseline separation and accurate quantitation could be achieved. The limits of quantitation (LOQs, S/N = 10) were in the range of 4–20 μg∙kg⁻¹. The average recoveries at the three spiking levels of 20, 100, 200 μg∙kg⁻¹, ranged from 75.50 % to 108.49 % in meat matrix, and the RSDs of peak area were ranged from 1.46 % to 13.03 %, showing good accuracy and precision. The method has been successfully applied in the determination of glutamyl peptides isomers in five meat samples, indicating the good performance and application prospects for the rapid screening of taste-active substances.

To improve nutrient supply assessments, the present study aims to provide comprehensive, updated nutrient data for a variety of milling products of wheat species (including bread wheat, spelt and durum wheat) and rye in Germany. With the help of an elaborate sampling plan, samples were generated that were as representative as possible for the entire country. Starch emerged as the predominant constituent in all milling products, except in brans and germ. In bread wheat bran, spelt bran and bread wheat germ, dietary fiber (DF) and protein were dominant. Rye wholemeal flours stood out for high DF contents. In general, AOAC Official Method 2011.25 yielded higher DF contents than existing data due to the inclusion of low molecular weight-soluble DF. Bran products exhibited high vitamin and element concentrations, while selenium concentrations varied regionally in wheat and spelt products. This study characterized the nutrient composition of different milling products, confirming highest concentrations of most nutrients in bran, germ and wholemeal products. This comprehensive overview adds great value to the assessment of nutrient supply due to the importance of milling products for human nutrition. This research provides updated nutrient data of the most important milling products in Germany.
