A total of 28 olive oil (OL) samples were collected from various regions and production years in Jordan. These samples were analyzed for viscosity, AV, saponification values, TPC, TFC, and DPPH free radical scavenging assay. The results showed variability among the OL samples in terms of viscosities (0.0523 ± 0.0002—0.0658 ± 0.0000 Pa*s),, AV g (0.12 ± 0.02—1.46 ± 0.10% oleic acid), and saponification value (88.90 ± 0.61–199.80 ± 0.30 mg KOH/g sample). The analyzed OL samples were classified as either extra virgin or of virgin grades. The TPC varied among the OL samples tested based on various regions and year of production, ranging from (0.07 ± 0.01—0.97 ± 0.04 mg GA/g sample), while TFC detected ranged from (0.01 ± 0.01—0.39 ± 0.06 mg RU/g sample). As for the antioxidant activity, all OL samples exhibited DPPH radical scavenging capacities (4.10 ± 0.90—41.80 ± 0.30%). To our knowledge, this study is thought to be the first investigation examining the quality and quantity parameters of various OL samples collected from various regions and years in Jordan as well as for their antioxidant activities. Despite the differences detected in all tests, no significant differences were found concerning the region of OL production. As for the year of production, significant differences were only found in the viscosities and TFC of OL samples produced in 2020 and 2021, being significantly higher the latter year. The findings of this study show that collection region, did not exhibit any significant change on the OL samples based on the tested parameters, While the year of collection resulted in a significant difference in viscosities [F (2, 25) = 3.95, <i>p</i> = 0.032] and TFC [F (2, 25) = 7.76, <i>p</i> = 0.002] among OL samples tested. This study adds to the existing literature regarding Jordanian OL samples’ characteristics and warrants for further investigation, particularly in influence of production year on viscosities, TFC, and other quality parameters..\u0000</p></div>","PeriodicalId":561,"journal":{"name":"Food Analytical Methods","volume":"18 7","pages":"1398 - 1408"},"PeriodicalIF":3.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article addressed the dual-adulterant sensing system because it overcame the limitations of traditional single-adulterant detection methods. This method enhances detection accuracy and provides a more reliable tool for food safety regulation. So for this purpose, a Ag/Cu@thio nanosensor was fabricated by chemical reduction method and characterized through scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), energy dispersive X-ray (EDX), thermogravimetric analysis (TGA), atomic force microscopy (AFM), and UV–vis spectroscopy that confirmed the synthesis of irregular shaped particles with an average size of 86 nm. Energy dispersive X-ray analysis confirmed the presence of required elements silver, copper, sulfur, and carbon in nanosensor highlighted their purity. Thermogravimetric analysis showed the decomposition event at 424 °C due to degradation of organic material after this plateau indicated the metallic residue left behind. The sensing ability of nanosensor was analyzed against urea and melamine which are common milk adulterants. The nanosensor demonstrated strong detection abilities for melamine and then for urea in milk with detection limits of 10 parts per million (ppm) and 12 ppm and percent recoveries 85% and 83%, respectively. Various experimental parameters, such as time, pH, temperature, and concentration of adsorbent and adsorbate, were optimized to maximize detection efficiency. The results showed that the Ag/Cu@thio nanosensor was more effective for melamine detection due to stronger electrostatic interactions between them as compared to urea. Recycling tests showed that the nanocomposite could be reused with a slight decrease in sensing performance.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":561,"journal":{"name":"Food Analytical Methods","volume":"18 7","pages":"1384 - 1397"},"PeriodicalIF":3.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study employs the discrete element method to model and simulate the cutting of <i>Rosa roxburghii</i>. By employing image processing technology, the contour and feature points of <i>Rosa roxburghii</i> were extracted, allowing the creation of a three-dimensional model. A discrete element model of <i>Rosa roxburghii</i> was constructed using the Hertz-Mindlin (no slip) with bonding model to generate the connection mode of dense packing of single spherical particles. The intrinsic parameters and basic contact parameters were determined through physical experimentation. The maximum shear force was employed as the evaluation index, and the Plackett–Burman test, the steepest ascent test, and the response surface method were used in combination to design the experiment and determine the significant factors and their optimal parameter combinations. Subsequently, the cutting process of four distinct blade shapes was simulated. The results demonstrate that the optimal parameter combination is a normal stiffness of 8.414 × 10⁸ N/m³ per unit area, a tangential stiffness of 6.306 × 10⁸ N/m³ per unit area, and a bond radius of 1.804 mm. The discrepancy between the simulated and actual maximum shear force for different blades is less than 8.65%.

Moreover, the processing of raw materials can facilitate food fraud, deceiving consumers and posing a threat to food safety; therefore, technologies for verification are necessary. The purpose of this study is to genotype the origins of commercial ginger powders using cleaved amplified polymorphic sequence (CAPS) molecular markers and to determine their actual content using TaqMan PCR. CAPS markers based on the restriction enzymes <i>Dra</i>I, <i>Cla</i>I, and <i>Bgl</i>II were successfully used to identify the origins of nine commercial ginger powders. The <i>Cla</i>I-based CAPS marker, in conjunction with the TaqMan PCR system, efficiently distinguished Chinese imported ginger (Cg) and Korean indigenous ginger (Bg) in commercial ginger powder, which was applied to measure their actual content. Among the nine commercial ginger powder samples, eight products were confirmed to be of Cg origin, while one product was found to be a mixture of Cg and Bg. Among them, seven had insufficient ginger content. Moreover, the degree of DNA degradation did not affect the PCR results, while long-term drying, autoclaving, and freeze-drying of ginger powder negatively affected PCR results. In this study, we report a molecular marker-based approach for genotyping the origin and measuring the actual content of commercial ginger powder.

Additionally, the study focused on evaluating the quality parameters of the extracted oil, including Rancimat oxidative stability, acidity value (AV), peroxide value (PV), total phenolic content (TPC), and antioxidant activity. These parameters were assessed over storage durations of 1, 30, and 60 days at a temperature of 4 °C. The findings indicated that treating MTS with cold plasma (CP) and ultrasonic treatment (UT) significantly enhanced the OEE by up to 29% for 15 min of CP treatment and 24% for 30 min of UT. Moreover, these treatments resulted in a notable reduction in AV (49% for CP and 46% for UT) and PV (38% for CP and 35% for UT) after 60 days of storage. Furthermore, the oil extracted from treated MTS exhibited a higher total phenolic content (74% for CP and 66% for UT) and increased antioxidant activity (156% for CP and 127% for UT) compared to samples obtained without any treatment. Additionally, the application of CP for 15 min led to a significant increase in α-tocopherol content (by 157%), while UT for 30 min resulted in a reduction of α-tocopherol by 76%.
