Discrimination of the geographic origin of cabbages

Determining the geographical origin of common buckwheat from China by multivariate analysis based on mineral elements, amino acids and vitamins

“…The element analysis is usually considered to be an effective tool, because plants can absorb the mineral elements from the soil and thus there is an association to some extent between the contents of mineral elements in environment and their accumulation degree in crops 17 , 18 . The method of element analysis has been applied for geographical origin assignment of some farm products such as wine 19 , honey 20 , mutton 21 , sheep milk 22 , 23 , Chinese cabbage 24 , 25 , tea 6 , coffee 4 , wheat 26 , 27 , and other crops 28 as well as some aquatic products 29 , 30 with different degrees of success. Besides, some organic compounds or physicochemical parameters (color, diastase activity, electrical conductivity, total antioxidant activity, etc.)…”

The Use of Wavelength Dispersive X‐ray Fluorescence in the Identification of the Elemental Composition of Vanilla Samples and the Determination of the Geographic Origin by Discriminant Function Analysis

“…Analytical techniques that have been used to determine the geographical origin of food products range from mass spectrometry techniques to separation techniques like HPLC and capillary electrophoresis (Luykx and van Ruth ; Zhao and others ; Sharp and others ; Bong and others ; Kim and others ). More recent studies involving spices have included the determination of the geographical location of Szegedi paprika using Sr isotope ratios and ICP‐MS (Brunner and others ) and the geographical origin differentiation of saffron spices using H, C, and N stable isotope analysis (Maggi and others ).…”

Multielement Analysis of Pakchoi (Brassica rapa L. ssp. chinensis) by ICP-MS and Their Classification according to Different Small Geographical Origins

“…Whereas, Chung et al distinguished verified cultivation regions of potato by the stable isotope composition analysis of bioelements [ 5 ]. The geographical origin of vegetables, such as cabbages, was also discriminated by 21 inorganic elements through ICP-MS analysis [ 6 ]. The data of elements compositions are often combined with multivariate statistical analysis, such as principal component analysis (PCA), to reduce the dimension of the data matrix, visualize the similarities and differences among samples, and identify the key discriminants distinguishing the samples [ 7 ].…”
