In this study, the geographical origin of longissimus dorsi meat from 'Nero dei Nebrodi' pigs reared in two distinct regions of north-eastern Sicily was indagated by correlating chemical-nutritional parameters, stable isotope composition, fatty acid and sterol profiles, and mineral element content. Significant differences (p ≤ 0.05) between the 'Nebrodi group' (NG) and the 'External Nebrodi group' (ENG) were found for 51 over 80 variables. The δ2H, δ18O, δ13C and δ15N of the defatted meat were statistically different (p<0.01) between NG and ENG animals, indicating a change in the composition of the diet and drinking water consumed. The results showed that the characteristic rich endemic vegetation of the Nebrodi influences not only the chemical-nutritional parameters of the meat but also its isotopic ratios, allowing for a geographical characterization required for the traceability of this peculiar product, aspiring to a protected designation of origin.

Phytosterols are bioactive and healthy components of the human diet. Although numerous investigations reported the rich nutrients in black goji berries, comprehensive data on the sterol pattern were missing. In this study, gas chromatography with mass spectrometry (GC/MS) analysis enabled the detection of 23 sterols and 22 fatty acids in dried black goji berry samples. Black goji berries were dominated by ∆5-avenasterol (mean: 23.7 %) > the rare campesta-5,24(25)-dienol (mean: 19.2 %) > β-sitosterol (mean: 14.9 %). Investigations of the reasons for this unique sterol pattern showed that ∼76% of the sterols in black goji berries were esterified with fatty acids (steryl esters). This share of steryl esters was higher than in virtually all other plant samples where free sterols are predominant. Remarkably, the rare campesta-5,24(25)-dienol was most prominent in the steryl ester fraction. Manual separation and analyses of seeds and pulp subsamples showed that most of the sterols were found in seeds where steryl esters were predominant (∼71 %), while the pulp was dominated by free sterols (∼73 %). Hence, the unconventional sterol pattern of black goji berries mainly originated from the high share of steryl esters in the seeds in combination with different sterol patterns in free and esterified sterols.

Non-essential trace elements (TEs) in food may cause adverse health effects. In this study, we evaluated the concentration of Ag, As, Ba, Cd, Pb, Sb, Tl, and V in 17 foodstuffs consumed in five cities located in the department of San Martin, in the Peruvian highland Amazon jungle. These included condiments, nuts, fruits, starches, and vegetables. To minimize the risks of cross-contamination and to ensure data quality, digestion and ICP-MS analyses were carried out in a metal-free, ultra-clean laboratory.
Barium was the most abundant element at concentrations in the mg/kg range, whereas the rest of the elements were present at trace levels (µg/kg). Only 30 % of the samples exceeded the international thresholds for Cd and Pb, with the greatest levels for Pb found in grapes (3.6 mg/kg) and for Cd in tomatoes (1.5 mg/kg).
According to the Hazard Index, both adults and children may develop non-carcinogenic effects if exposed to these elements. The cancer risk for As consumption was below the US EPA recommend values.
Our results highlight the importance of conducting more research to set food safety policies, especially in Latin America, aiming to reduce exposure of the population by adherence to regulations and enforcement by local officials.

Acetamiprid (AAP) is a renowned neonicotinoid insecticide for swift insect control that is prone to residue in agricultural products and threatens human health. Magnetic electrochemical sensor (MES) was developed for high-precision detection of AAP based on silver nanoparticle (AgNPs) and polydopamine (PDA) modified Fe3O4 nanocomposites (Ag@PDA@Fe3O4). The electrochemical signals generated by AAP hydrolysis and AgNPs oxidation are respectively used as two special signal sources. An increase in AAP concentration led to a proportional increase in the signal from AAP hydrolysis at +0.9 V (IAAP), while the signal from AgNPs oxidation at +0.27 V (IAg) correspondingly decreased. The output signal ΔIAAP/ΔIAg (R2=0.9890) demonstrates a superior linear relationship compared to ΔIAAP (R2=0.9790) or ΔIAg (R2=0.9740) alone. MES demonstrated a broad linear detection range from 0.01 to 2.00 mg L−1 and an impressive limit of detection (LOD, 3S/M) at 3.6 µg L−1. The incorporation of magnetic glassy carbon electrodes (MGCE) significantly mitigates the detachment of nanomaterials. MES has excellent stability and selectivity, and can successfully detect AAP in actual cowpea samples. This study provides pivotal insights into the design of nanomaterial-based ratiometric electrochemical sensors for the sensitive and selective detection of AAP.

Proteins are fundamental nutrients for sustaining human life. However, the rapid increase in global population and concerns about environmental sustainability have intensified the demand for diverse proteins sources. Addressing this demand, researchers are exploring a broader spectrum of alternative proteins derived from plants, animals, and microorganisms. This review provides a detailed examination of the sources, functional properties, extraction methods, and current research on alternative proteins. It also proposes a comprehensive assessment of their quality of alternative proteins as meat analogues, focusing on sensory properties, nutritional value, safety and sustainability. Furthermore, the alternative proteins face challenges, including the need for regulatory development and consumer acceptance. Therefore, with ongoing advancements in science and technology, alternative proteins present significant potential for future development.

Hollowness is a common defect in edamame with pod that affects its market value and yield. The similar appearance of hollow and normal edamame with pod makes detection and sorting challenging. This study utilized hyperspectral reflectance imaging and transmission imaging to detect hollow edamame with pods. Various classification models were constructed, including partial least squares discriminant analysis, support vector machine, random forest, artificial neural network, and linear discriminant analysis. Six preprocessing methods (SG, MA, MSC, SNV, DT, and WT) and three feature selection methods (SVC-SPA, CARS, and GA) were used to optimize the models. Based on the optimal model, the hollow regions of edamame were visualized, and the proportion of hollow areas was quantified. Based on the optimal threshold for hollow ratio, edamame classification was performed. Results indicate that the SG-SPA-SVM model, derived from hyperspectral transmission data using eight characteristic bands, achieved the best classification performance, attaining a classification accuracy of 98 % at a hollow ratio threshold of 0.48. It offers a scientific basis for quality assessment in related pod and the development of spectrometer applications in production sorting.

A novel miniaturized analytical method for the simultaneous determination of l-carnitine and its ester, acetyl-l-carnitine in fresh milk and milk products by microchip electrophoresis (MCE) with conductivity detection was developed. Under optimized separation conditions, separation voltage of 4 kV and 50 mmol L−1 acetic acid and 0.1 % methylhydroxyethylcellulose at pH 3.0 as background electrolyte, carnitines were sufficiently separated in less than 10 min. An elimination of adsorption of the cationically migrated analytes on a poly(methyl methacrylate) microchip was achieved by addition of 1 mmol L−1 triethylenetetramine to all analyzed samples. The detector response was linear in the range 0.2–1.5 µg mL−1 for l-carnitine and 0.4–2.0 µg mL−1 for acetyl-l-carnitine. The LOQ values were 0.1 µg mL−1 and 0.4 µg mL−1 for l-carnitine and acetyl-l-carnitine, respectively. Recoveries of the analytes in the analyzed samples were in the range 87.5–97.8 %. The developed MCE method has been successfully applied to the analysis of carnitines in eight milk products after a sample pretreatment which included precipitation, centrifugation, and filtration. The developed MCE method has a low hazardous impact on human health and the environment.

Sea cucumbers increasingly consumed as a premium part of traditional diet in Middle East provide viable reservoir of chemical entities with potential significance. The current work aims to monitor metabolome patterns of Holothuria atra following salting and cooking treatments and their entanglements on anticoagulant potential using UPLC-MS/MS combined with chemometrics. A total of 64 peaks encompassing fatty acids, phospholipids, triterpene glycosides, flavonoids, phenolic acids, carotenoids and phytosterols were chemically profiled. Given this analysis, fatty acids and carotenoids witnessed an obvious increasing trend in fresh and cooked sea cucumber samples. Cooked and salted samples relatively augmented phenolic acids, flavonoids and triterpene glycosides. OPLS-DA underscored clear discrimination among the comparable samples highlighting lysoPC 16:0, cucumariaxanthin B, astaxanthin and arachidonic acid as focal discriminators of fresh samples while pyrogallol, ellagic acid and kaempferol-O-rhamnoside were the determining metabolites of cooked samples. Successively, the differential markers enriched in salted ones included chlorogenic acid, holothurin B and betulinic acid. Experimentally speaking, the sea cucumber samples exerted noteworthy dose and time-dependent anti-clotting potential. OPLS derived coefficient plot portrayed that chlorogenic acid, β-tocotrienol, holothurin B and betulinic acid dramatically augmented during salting treatment synergistically mediated anticoagulant efficacy. These findings pursue concept of nutritional therapy to rectify thromboembolic disorders.
海参作为中东地区传统饮食的重要组成部分，被越来越多的人食用，它提供了具有潜在意义的化学实体宝库。目前的研究旨在利用 UPLC-MS/MS 结合化学计量学方法，监测盐渍和烹饪处理后 Holothuria atra 的代谢组模式及其对抗凝血潜力的影响。对脂肪酸、磷脂、三萜糖苷、类黄酮、酚酸、类胡萝卜素和植物甾醇共 64 个峰进行了化学分析。分析结果表明，新鲜海参和熟海参样品中的脂肪酸和类胡萝卜素呈明显增加趋势。煮熟和腌制海参样品中的酚酸、类黄酮和三萜糖苷含量相对较高。OPLS-DA 突出了同类样品之间的明显区别，突出显示溶菌酶蛋白多糖 16:0、黄瓜黄素 B、虾青素和花生四烯酸是新鲜样品的重点鉴别物，而焦棓醇、鞣花酸和山奈酚-O-鼠李糖苷则是熟制样品的决定性代谢物。盐渍样本中富含的差异标记物先后包括绿原酸、冬青皂苷 B 和白桦脂酸。实验表明，海参样品具有显著的剂量和时间依赖性抗凝血潜力。OPLS 导出的系数图显示，盐渍处理期间，绿原酸、β-生育三烯酚、冬青皂苷 B 和白桦脂酸协同介导的抗凝功效显著增强。这些研究结果体现了营养疗法治疗血栓栓塞性疾病的理念。

At room temperature, an air-assisted rapid synergistic cloud point extraction (AA-RS-CPE) method based on deep eutectic solvent (DES) was presented to determine Zn (II) traces in various samples. Nonanoic acid and L-menthol formed the synergistic reagent (DES) in a 2:1 mol ratio to reduce both time and cloud point temperature. Air cycles were used to maximize recovery and accelerate cloudy solution formation. The 4,4-dimethyl-2,6-dioxo-N-phenylcyclohexanecarbothioamide (DDPCCTA) and TritonX-100 were used as ligand and surfactant, respectively. The validation parameters, including the calibration curve linearity (0.2–900 µg L−1), the limit of detection (LOD = 0.10 µg L−1), the enhancement factor (EF = 120), and the preconcentration factor (PE = 100), were calculated. Additionally, the accuracy of the AA-RS-DES-CPE approach was proved by two certified reference materials (CRMs). Finally, the three greenness tools, the Blue Applicability Grade Index (BAGI), the Sample Preparation Metric of Sustainability (SPMS), and the Analytical Greenness Metric for Sample Preparation (AGREEprep), were used to evaluate the environmental sustainability values, health hazards, and applicability of this method. This approach was improved to be safer and more environmentally friendly than existing methods, with high application potential.

Food composition tables and databases (FCTs) and Nutrient Conversion Tables (NCTs) are essential for nutrition research. Compiling a new NCT requires multiple FCTs, usually with incompatible formats. FCT cleaning and standardisation is rarely reproducible and requires significant resources. Our aim was to develop a framework and tools for compilation and reporting of reproducible FCTs/NCTs, through expanding the fish and other aquatic products in the global NCT for the Food and Agriculture Organization of the United Nations (FAO) Supply and Utilization Accounts.
FAO/ International Network of Food Data Systems (INFOODS) guidelines, and open science tools were used for processing. New R functions and scripts were developed to: import and standardise 12 FCTs; re-calculate food components; perform quality checks; and format outputs (e.g., spreadsheets).
This resulted in the expansion of the global NCT, providing information on 32 food components for 95 fish and other aquatic products. The workflow takes 160 s to run. The scripts are publicly available in GitHub, with a manual, and can be used or adapted.
These open science tools provide a novel resource to create, update and expand FCTs/NCTs in a reproducible, reusable, efficient, and transparent manner, for use in nutrition research. food composition data for nutrition research.
