Abstract:
... Quinoa is an Andean grain that is attracting attention worldwide as a high-quality protein-rich food. Nowadays, quinoa foodstuffs are susceptible to adulteration with cheaper cereals. Therefore, there is a need to develop novel methodologies for protein characterization of quinoa. Here, we first developed a matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) ...

Abstract:
... The growing concerns about the quality and safety of herbs and spices among consumers have increased the demand for technical testing. Recently, non-destructive analysis techniques have been widely studied and applied. Generally, a single technology has certain limitations, which are not enough to fully describe the characteristics of complex products (dynamic or complex structure). Combining non- ...

Abstract:
... There has been an increasing demand for the rapid verification of fish authenticity and the detection of adulteration. In this work, we combined LIBS and Raman spectroscopy for the fish species identification for the first time. Two machine learning methods of SVM and CNN are used to establish the classification models based on the LIBS and Raman data obtained from 13 types of fish species. Data f ...

Abstract:
... Offal tissues carry a lower market value compared to skeletal meats in some global markets. The inclusion of offal in any meat product in the EU and UK must be declared on the label. While many technologies have been applied to the challenge of determining adulteration with offal in meat products, no single method has been recognised and validated as a reliable test to support legislative requirem ...

Abstract:
... A green screening method to determine cashew nut adulteration with Brazilian nut, pecan nut, macadamia nut and peanut was proposed. The method was based on the development of a one-class soft independent modelling of class analogy (SIMCA) model for non-adulterated cashew nuts using near-infrared (NIR) spectra obtained with portable equipment. Once the model is established, the assignment of unknow ...
... Escolar or oilfish being sold as cod is a worldwide concerning food counterfeiting issue. This study established a simple and rapid real-time recombinase polymerase amplification (RPA) assay for oilfish (Ruvettus pretiosus) and escolar (Lepidocybium flavobrunneum) detection. The assay uses RPA primers and a probe designed for the intraspecific conserved and interspecific regions in the COI and Cyt ...

Abstract:
... Traditional approaches to characterize edible oils such as chemical, chromatographic and light absorption techniques are laborious, expensive, and bulky to implement. This paper presents the electrochemical impedance spectroscopy of 13 types of edible oils, a rapid robust approach to characterizing the electrical behavior of oils without sample preparation. This is achieved through probing the oil ...
... Butteroil is valuable product appreciated for its sensory characteristics, economic importance, and social/cultural significance, as it has similarities in several regions of the world. Due to its high added value, this product is susceptible to adulteration by replacing authentic butteroil with other cheaper fats, or even by expired butteroil. Detection of butteroil adulteration demands chemical ...
... Adulteration of essential oils is a common and serious problem. Adequate and fast methods are required to establish the authenticity and purity. GC-MS, ¹H and ¹³C NMR were compared in combination with similarity calculations as well as differential spectroscopy and chromatography for the authentication and determination of purity of vetiver essential oils. In the investigation of eight commercial ...

Abstract:
... According to the Multiplicative Hyperbolic Model (MHM), the value of a reinforcer is an increasing hyperbolic function of its size (q). Recently reported results indicated that dilution of a sucrose solution reduced its reinforcing value by increasing the ‘size-sensitivity’ parameter of this function and reducing its maximum. The present experiment examined whether adulterating a sucrose solution ...

Abstract:
... The fishmeal adulteration identification based on microscopic image and deep learning was studied in this paper, which included the qualitative identification and component recognition of adulterated fishmeal. Mobilenetv2 was chosen as the qualitative identification model to distinguish between fishmeal samples and adulterated samples. And the accuracy, precision, recall, and F1-measure of the tes ...

Abstract:
... Carnaroli is a high quality and priced variety, being considered as one of the finest Italian rice varieties due to its sensorial and rheological properties and, thus being a potential adulteration target. The present work aimed at exploiting polymorphisms in the Alk (A/G and GC/TT in exon 8) and Waxy ((CT)n and G/T in intron 1) genes by HRM analysis to differentiate Carnaroli rice from closely re ...

Abstract:
... Paprika is a widely consumed spice in the world and its authentication has gained interest considering the increase in adulteration cases in recent years. In this study, second-order fingerprints acquired by liquid chromatography with fluorescence detection (HPLC-FLD) were first used to detect and quantify adulteration levels of Chinese paprika samples. Six different adulteration cases, involving ...

Abstract:
... With the increasing demand for natural products by the consumer in the marketplace it is necessary to see a proportional increase in behind-the-scenes science to ensure that the ideology of safety and honesty, that is justifiably expected by the wider public, is adequately satisfied. It is of essence to have a fair yet firm governance of nutraceuticals, cosmetics, therapies, and foods. However, wi ...

Abstract:
... The authenticity of rice has become an important issue over the last few years. Many techniques have been employed in rice authentication including geographical origin, cultivar discrimination, organic rice authenticity, and impurities detection in rice. This review paper is attempted to highlight the current literature (past twenty years) on the discrimination and authentication of rice using dif ...
