“…Isotopic ratios of 13 C/ 12 C, 15 N/ 14 N, 18 O/ 16 O, 2 H/ 1 H, and 34 S/ 32 S are usually analyzed by isotope ratio MS (IRMS). For the determination of isotope ratios, the analytes must be converted to the gas phase-H 2 , N 2 , CO, CO 2 , and SO 2 -before ionization.…”

“…Mahne Opatić et al [38] studied the geographical origin of organic cultivated potatoes (Solanum tuberosum L.) from four regions of Slovenia: Alpine, Dinaric, Mediterranean, and Pannonian macroregions. Samples were subjected to stable isotope analysis of the major bio-elements (δ 13 C, δ 15 Ν, δ 18 O, δ 34 S) and to element profiling (Na, Mg, P, S, Cl, K, Ca, Mn, Fe, Ni, Cu, Zn, Mo, Br, Rb, Sr), which included the rare earth elements (Sc, Y, Nb, La, Ce, Pr, Nd, Dy, Er). The classification was successful among the four groups of the Alpine, Dinaric, Mediterranean and Pannonian macro-regions, with an overall success rate of 100% obtained.…”

This study is a systematic literature review of geographical origin authentication by elemental analytical techniques. Authentication and certification of geographic origin of agri-food products is a useful tool toward the protection of the quality for products. The aim of this work was to map the current state of research in the area of agricultural products and food, identifying emerging fields to the geographical origin of products. The article is divided in three parts. The first part of the article deals with the analytical techniques applied in the food authentication. Special mention is made to elemental analysis and multiple isotope ratio. The second section focuses on statistically published data concerning published research for geographical origin authentication for the period 2015–2019. Specific results are presented inter alia: number of articles according to the type of product, articles according to the type of the analytical techniques, and others. The third part contains characteristic results from articles that were published in the period 2015–2019, on certification of geographical origin on specific agricultural products.

Food plays a vital role in our daily life. Providing good quality food to consumers is essential. Food quality can be accessed using the Electronic nose. Electronic nose (E-nose) is an instrument for odor analysis. E-nose mimics the human olfaction system. It is widely used in predicting the quality of foodstuffs and detecting the contamination in foods. E-nose can also be used in outdoor monitoring such as air quality monitoring and detect the hazardous odors emitted wastewater treatment plants. Application of Enose is increasing day by day. In this paper, we consolidated the previous works on E-nose. They had applied different machine learning algorithms to construct a model. In most of the works, for the classification of data, they used Support Vector Machine and Linear Discriminant Analysis, which shows higher accuracy when comparing to other algorithms.

“…With the advantages of high resolution, good sensitivity, short cycle and wide scanning range, ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS/MS) is widely used in studying the compositions of TCM [13,14]. Additionally, the analysis methods of chemometric, such as partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA), can be adopted to analyze the differences between two groups of multiple variables [15][16].…”

Background: Wen-Dan decoction (WDD) is a traditional Chinese medical prescription composed of six herbs for the treatment of neurological diseases. The research of classic prescription (CP) is the hotspot in China which aims to develop the ancient and highly effective prescriptions into modern formulations under the condition of ancient dosage. In order to clarify the effects of ancient and modern techniques on WDD in the research of CP, the compounds in WDD should be systematically studied first, and the issue whether there are significant differences on components even efficacy between different preparation processes has to be explored.Methods: In this study, ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry was employed to analyze the components of WDD rapidly in both positive and negative ion mode. The analysis methods of chemometric, such as partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA), was innovatively adopted to compare three typical processes (ancient decoction process, modern decoction process and modern alcohol precipitation process).Results: The 121 compounds were identified in WDD, including 23 organic acids, 69 flavonoids, 4 amino acids, 5 phenylpropanoids, 6 triterpenoid saponins and 14 other components, and most of them were from Zhishi (Immature orange fruit), Chenpi (Dried tangerine peel) and Gancao (Liquorice root). Additionally, significant differences between three processes were proved in this study, and 24 components were considered to be related to the differences between ancient and modern technology, as well as 18 compounds could be affected in the process of alcohol precipitation. The relative content of compounds in modern decoction process was higher than that in ancient decoction process, indicating the extraction efficiency of modern technology was greater than that of ancient process. Conclusion: The chemical profiling of WDD provided the bases for the study of active components and quality control. The obvious differences among three processes suggested that the content of active ingredients in the study of CP should be strictly controlled to ensure the transfer of significant efficacy from ancient prescriptions to modern formulations.
