“…Kukusamude and Kongsri showed 100% correct classification of their origin groups and 75.5% cross‐validation in the discrimination of Thai rice from different provinces in Thailand. Magnesium, chlorine, and arsenic were good indicators for origin identification of rice from central and western parts of the Thung Kula Rong Hai area, as well as between Mahasarakham and Surin provinces.…”

“…Other factors including the absorbability of the plant, chemical state of the soil, climate, microorganism activity, pesticide use, pollution, water, cultivation practices, and processing methods can also cause elemental concentration differences. These differences have been determined using various analytical techniques such as wavelength dispersive X‐ray fluorescence (WDXRF), inductively coupled plasma–mass spectrometry (ICP‐MS), isotope ratio–mass spectrometry (IRMS), and laser ablation–inductively coupled plasma–mass spectrometry (LA–ICP–MS) and have been used for geographical origin determination . More recent work includes the origin determination of cocaine, marijuana, and synthetic cannabinoids using elemental content measured by ICP‐MS .…”

Kratom is a plant material exhibiting both analgesic and stimulant effects and is also forensically relevant since it is abused as a “legal high.” It is regulated in several countries but not scheduled in the United States at the federal level. This study used inductively coupled plasma–mass spectrometry (ICP–MS) to measure the concentrations of 13 elements in 19 kratom samples obtained from an online distributor selling kratom, from Borneo, Malaysia, Indonesia, Thailand, and Vietnam, for the purpose of using the elements to discriminate among purported country of origin, “suborigin,” and strain. Analysis of variance revealed statistical differences in concentrations of elements from each group, while discriminant function analysis (using leave‐one‐out classification) successfully classified kratom samples by their purported country of origin (100%), “suborigin,” (100%), and strain (86%). Our method illustrates the possibility of utilizing ICP–MS for determination of commercially available kratom samples by purported origin, “subororign,” or by product line.

“…In the EU, this approach has been applied since the late 1990s to trace the geographical origin of agricultural and food products such as cereals [29][30][31][32][33][34][35][36][37][38] , meat 26,[39][40][41][42][43][44][45][46][47][48][49][50] , dairy products [51][52][53][54][55][56][57][58] , olive oil [59][60][61][62] , honey [63][64][65][66] , coffee, and tea [67][68][69][70][71][72][73][74][75] . Table 1 shows a list of previous studies that traced the geographical origin of food materials using stable isotope analysis, mainly since 2000.…”

High-value agricultural products are characterized by the geographical conditions of the production areas such as climatic and soil conditions. These products are protected by the geographical indication (GI) protection system, which has been currently introduced in more than 100 countries. GI products are expensive in the market, and they are often mislabeled. Thus, there is an urgent need for the development of analytical methods that enable the tracing of geographical origins of food materials. Stable isotope analysis is used to trace the geographical origin of food materials. In this study, we review the applications of tracing the geographical origin of agricultural products (especially rice, beef, and honey) using an analytical method that focuses on analyzing stable isotopes (δD, δ 13 C, δ 15 N, δ 18 O, and δ 34 S).

“…Many techniques have been developed to distinguish cultivation areas of rice and other cereals [3], such as the stable isotope technique [4][5][6][7][8][9], near-infrared technique [10,11], Raman spectroscopy [12], 1 H-NMR spectroscopy [13], and multielement analysis [14][15][16]. However, it is still di cult to discriminate the geographical origins, especially the adjacent production areas with the same climate type and similar geologic bedrock, because the di erences in " ngerprints" are relatively small and the geographical traceability is more di cult [17,18].…”

The study aims to investigate whether the multielement analysis result can be used as a fingerprint to identify the geographical origin of Wuchang rice. The element contents of rice and soil samples from three regions in China (Wuchang, Qiqihar, and Jiamusi) were analyzed. The concentrations of 16 elements (Na, Mg, Al, K, Ca, V, Mn, Fe, Co, Cu, Zn, As, Rb, Sr, Cd, and Pb) in 194 rice samples and 112 soil samples from the harvest season in 2013 and 2014 were determined. The analysis of variance and linear discriminant analysis were performed to analyze the variation among regions and rice genotypes and classify the geographical origins of rice. Only the element of Cu showed significant differences among different genotypes. In the discriminant analysis, the overall correct identification rates of the rice samples obtained in 2013 and 2014 were, respectively, 96.6% and 89.6% and the overall correct identification rate for Wuchang rice reached 100%.
