“…In many human populations foods are non-locally grown and may derive from a huge range of geographical origins (e.g. 36 ). The input of oxygen and hydrogen from these globally homogenized food sources into hair and nail will dampen the expected tissue variation based on local d 18 O and dD values in drinking water.…”

“…Firstly, an LDA model was developed, which is a model that has been used in many food authenticity studies (e.g. Kelly et al 2005;Laursen et al 2014). Secondly, a naïve Bayesian classifier using kernel-density estimation of the variables was evaluated using the same data set.…”

“…This regulatory shift has spurred the development of new techniques for the discrimination between foods of different origins, sources and farming systems. Stable isotope analysis of specific elements, including: hydrogen, carbon, nitrogen, oxygen, and sulfur, has been applied in food authentication for more than 20 years (Kelly, Heaton, & Hoogewerff, 2005;Rossmann, 2001 …”

Keywords:Isotope ratio mass spectrometry Gas chromatography Geographic origin Food products authenticity Linear discriminant analysis Likelihood ratio Bell peppers Capsicum annuum a b s t r a c t Two approaches were investigated to discriminate between bell peppers of different geographic origins. Firstly, d 18 O fruit water and corresponding source water were analyzed and correlated to the regional GNIP (Global Network of Isotopes in Precipitation) values. The water and GNIP data showed good correlation with the pepper data, with constant isotope fractionation of about À4. Secondly, compoundspecific stable hydrogen isotope data was used for classification. Using n-alkane fingerprinting data, both linear discriminant analysis (LDA) and a likelihood-based classification, using the kernel-density smoothed data, were developed to discriminate between peppers from different origins. Both methods were evaluated using the d 2 H values and n-alkanes relative composition as variables. Misclassification rates were calculated using a Monte-Carlo 5-fold cross-validation procedure. Comparable overall classification performance was achieved, however, the two methods showed sensitivity to different samples. The combined values of d 2 H IRMS, and complimentary information regarding the relative abundance of four main alkanes in bell pepper fruit water, has proven effective for geographic origin discrimination. Evaluation of the rarity of observing particular ranges for these characteristics coul...

“…According to Kelly et al (2005), unique signs and information of food origin are offered by composition and structure of soil. Chemical and isotopic composition (separately or together) determine the basic characteristics of the food which has been used for last thirty years (Bontempo et al, 2011).…”

Abstract:Traceability concept that is often discussed together with foodborne problem has been developed rapidly with technology and it is key position of safety and quality of food. As a result of globalization, food production and consumption locations become distant. Therefore, the importance of traceability work is increasing. Origin of the food that the starting point of the food traceability is the first step of traceability. Determination of food origin are important in traceability as a key of food quality and safety. Food safety and traceability is impossible in food that could not be determined origin. The main aim of this study is investigate the method to determine the origin of the food. Origin detection means is considered as an important part of the food traceability. The methods used in order to determine the origin of the food is divided into as geographic-based and analytical methods. Geographicbased origin determination methods are evaluated in two subgroups as mineral isotope and GIS (Geographical Information System). Analytical and bio-based tools, DNA, enzymes, mass spectrometry, spectroscopy, and based on electrokinetic and separation were examined by making detailed literature search.
