“…It is mainly produced and consumed in UK, Ireland, France and Spain. A study was carried out in Spain in order to distinguish the two main production areas: Austurias and Basque country [67]. Before the use of Sr isotopic ratio, various techniques had been used to study the origin of cider: polyphenolic composition [68], multi-elemental concentration [49,69,70], H, C, N, O and B stable isotope ratios [71,72].…”

and ends with man. The environment-food interaction is clear, and the production of safe and quality food is an indispensable condition for human health. The globalization of the markets, in particular of food markets, means that a greater variety of food is proposed to consumers who want to know more about its geographical origin and characteristics. For this aim, food traceability is a tool of primary importance because it acts on both food safety and quality, in order to satisfy the needs of a demanding consumer, who is interested in the quality of the food he eats and in the controls about the veracity of the brands which protect it [1, 2]. The production of high-quality food is the first step to satisfying other important aspects, such as the development of a productive but sustainable agriculture and the control of marketing. Frequently, all this is delegated to the "labelling", which is incomplete by nature or easily manipulated. Only the use of a scientific method of identification and control of the geographical origin, independent of the "labelling" and therefore of the producer, enables us to answer in full important questions concerning food safety, food quality and consumer protection. In order to achieve good results in this field, a basic mandatory condition is to develop suitable "robust" analytical methods which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds; the latter are fuelled by the modern ease of transport and conservation of products in world markets. Numerous chemical, biological and genetic methods have been developed over time in order to verify the origin of foods [3]. In this paper, we will focus on mass spectrometry, in particular on the 87 Sr/ 86 Sr isotopic ratio measurement, in that it is a "robust" analytical technique, able to fulfil the requisites needed for traceability, both to satisfy the veracity of the geographical origin and to trace possible contaminated foods back to their origin. In particular, due Abstract Today, food traceability needs to develop suitable "robust" analytical methods, in terms of the precision and of the reliability of results, which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds. This review paper highlights the most recent results obtained with the use of the 87 Sr/ 86 Sr isotopic ratio technique, when applied to the traceability of the origin of different foods for human consumption, such as vegetables, beverages, dairy products, and meat and fish products. The instrumental techniques, with the relative methodologies and the quality of the final results, will be examined and commented.

“…At present, the fingerprint technique has become one of people's research hotspots, and there have been some very good research reports. The reports include organic mass spectrum [6][7][8][9], inorganic element [10][11][12][13], biochemistry [14][15][16], HPLC [17,18], GC [18][19][20], CE [21], NMR [7,22], UV [7,23] and IR fingerprints [23][24][25][26][27][28][29], etc. Among the techniques, the application research of chromatographic fingerprint are the most prevalent and in-depth due to its traits of qualitative, quantitative and multidimensional information, and has been used in the fingerprint analyses of extraction solution and volatile components of samples.…”

The thermodynamic systems and dynamic model suitable for determining the nonlinear chemical fingerprints of samples were analyzed. The results indicated that the damp nonlinear chemical reactions in close systems away from the equilibrium and open systems without the complementarity of the dissipation substances have important significance for the throng characterization and whole content analysis of chemical components in samples. Various factors influencing on nonlinear chemical fingerprint, such as reactant species and their concentrations, electrode types, temperature, stir rate, the sort, dosage and granularity of the sample, etc. were amply researched by a nonlinear chemistry reaction, namely, damp B-Z oscillation which used acetone and glucose as the main dissipative substances. In addition, the quantitative information on the whole of chemical components in samples and the traits and applications of the fingerprint were investigated. The method and its important conditions for determining nonlinear chemistry fingerprint used in distinguishing and evaluating complex samples were successfully put forward.nonlinear chemical fingerprint, dissipative components in samples, determining method, condition factor, authenticity identification, quality evaluation, sample
