“…However, the benefits of using XRF compared to AAS or ICP-OES rely on sample preparation, as direct analysis of samples (in all forms, e.g., solid, liquid, and gel) can be carried out in a concise time frame of analysis (∼60 s) without requiring organic solvents or acids (Pashkova, Aisueva, et al, 2018). Therefore, it can be easily applied for fast in-line mineral profile analysis of milk and dairy products (mainly powders), with values very consistent with those reported in the literature using different methods (Table 1) (W. P. McCarthy et al, 2020;Pashkova, 2009;Pashkova et al, 2016;Pashkova, Aisueva, et al, 2018;Pashkova, Smagunova, et al, 2018). For example, Perring and Tschopp ( 2019) established and validated a rapid method for quantifying the total ash content of 69 different powder milk-based ingredients using Energy Dispersive-X-Ray Fluorescence (ED-XFR).…”

Calcium (Ca) is a key micronutrient of high relevance for human nutrition that also influences the texture and taste of dairy products and their processability.In bovine milk, Ca is presented in several speciation forms, such as complexed with other milk components or free as ionic calcium while being distributed between colloidal and serum phases of milk. Partitioning of Ca between these phases is highly dynamic and influenced by factors, such as temperature, ionic strength, pH, and milk composition. Processing steps used during the manufacture of dairy products, such as preconditioning, concentration, acidification, salting, cooling, and heating, all contribute to modify Ca speciation and partition, thereby influencing product functionality, product yield, and fouling of equipment. This review aims to provide a comprehensive understanding of the influence of Ca partition on dairy products properties to support the development of kinetics models to reduce product losses and develop added-value products with improved functionality. To achieve this objective, approaches to separate milk phases, analytical approaches to determine Ca partition and speciation, the role of Ca on protein-protein interactions, and their influence on processing of dairy products are discussed.

“…Serious overdose of pesticide residues can cause acute intoxication, while mild pesticide residues chronically accumulated in human body can also cause many chronic diseases. At present, the widely used methods for pesticide residue detection are liquid chromatography [43], gas chromatography mass spectroscopy [44] and fluorescence analysis [45]. The accuracy of these methods is very high, but the pretreatment processes are very tedious, which is difficult to meet the rapid and on-spot detection in fruit and vegetables.…”

Preparation of a Novel SERS Platform Based on Mantis Wing with High-Density and Multi-Level “Hot Spots”

et al. 2019

The recent development of SERS substrates based on irregular nanostructures for directly molecule recognition has aroused increasing attention. By combining the irregular flake-like nanostructures of mantis wings, high SERS performance of Ag nanofilms, and the chemical stability of Au nanoparticles (NPs), an ultra-sensitive and flexible SERS substrate based on Au NPs functionalized Ag nanofilms-mantis wings (Au-Ag-M.w.) hybrid system is successfully fabricated. When 4-aminothiophenol is selected as the probe molecule, the limit of detection (LOD) is as low as 10−13 M and the relative standard deviation (RSD) is lower than 7.15%. This novel SERS platform exhibits high SERS performance in terms of sensitivity, reproducibility and practicability mainly because there are high-density and multi-level “hot spots” in the appropriate nanogaps. Meanwhile, it also systematically compares the differences of the SERS performance of Cu and Ag decorated M.w. hybrids and how these differences can alter their response. Moreover, the proposed substrate is employed to rapidly detect the pesticide residues on apple peels and the LOD for cypermethrin is estimated at 10−10 mg/mL. Therefore, this novel SERS substrate has great potential in rapid sampling of pesticide residues on real samples and expands the investigation to other natural materials for fabricating various SERS platforms.

“…In the WD system, the emitted polychromatic beam emerging from the sample surface is dispersed into its monochromatic components (wavelengths) with an analyzing crystal, whereas the ED approach measures the intensity of the photon energy of the individual X-rays generated. It is well accepted that WD-XRF has superior sensitivity (LOD of 8.0 mg kg -1 vs 1 mg kg -1 of ED-XRF) and resolution, fewer spectral overlaps and lower background intensities (Pashkova et al, 2018). Anyway, the WD-XRF configuration is reported to be less employed in milk and dairy product analysis due to the higher price compared with ED-XRF (Habib-Ur-Rehman, Rehana & Yawar, 2012).…”
