“…According to Tiezen et al (1983), the main biochemical fractions of the body are isotopically different, which may reflect differences in their biochemical composition. Tissues containing higher lipid content would probably have lower d 13 C values as compared to those with lower lipid content, which are relatively poorer in carbon-13 (Tiezen et al, 1983;Piasentier et al, 2003). Similar behavior was observed in treatments T4, T5, T6, and T7, which feeds contained mixtures of different animal proteins, as compared to the control treatment (Figures 4, 5, and 6) in the three analyzed tissues.…”

“…The isotopic ratio of the chemical element nitrogen ( 15 N/ 14 N) allowed the certification of the geographical origin and feeds of sheep (Piasentier et al, 2003), as well as to determine the feeding ecology of sharks (Domi et al, 2005), quality of oysters produced in impacted areas (Piola et al, 2005), and feeding studies of seals raised in captivity (Zhao et al, 2006). According to Oliveira (2005), the technique of carbon and nitrogen stable isotopes can be used as a tool to trace the inclusion of animal byproducts in broiler feed diets by analyzing the isotopic ration in the breast muscle, keel, and tibia.…”

Consistent information on meat products consumed by the public is essential. The technique of stable isotopes is a powerful tool to recover consumers' confidence, as it allows the detection of animal byproduct residues in poultry meat, particularly in quail meat. This study aimed at checking the presence of poultry byproduct mixtures in quail diets by applying the technique of carbon ( 13 C/ 12 C) and nitrogen ( 15 N/ 14 N) stable isotopes in quail breast muscle, keel, and tibia. Sixty four one-day-old male quails were obtained from a commercial farm. Birds were housed in an experimental house from one to 42 days of age, and were randomly distributed into 8 experimental treatments, and fed diets containing poultry offal meal (POM), bovine meat and bone meal (MBM) or poultry feather meal (PFM), or their mixtures. Four birds per treatment were slaughtered at 42 days of age, and breast (Pectoralis major), keel, and tibia were collected for analyses. The inclusion of animal byproducts in quail diets was detected by 13 C e 15 N analyses in the tissues of the birds; however, it was not possible to specify which byproducts were used. It was concluded that quail meat can be certified by the technique of stable isotopes.

-Mid-infrared (MIR) and front-face fluorescence spectroscopies, coupled with chemometric techniques, were investigated for their potential for discriminating Emmental cheeses originating from various geographic origins. A total of 74 Emmental cheeses, produced during summer, from six countries, i.e., Denmark (n = 2), Finland (n = 4), Germany (n = 6), Austria (n = 8), France (n = 27) and Switzerland (n = 27) were analysed. Within the 1500-900 cm -1 spectral region, a good classification of samples was obtained for 83.7 and 77% of the calibration and validation data sets, respectively. Within the 3000-2800 cm -1 the classification was considerably worse (only 57.4 and 29.7% for the calibration and validation spectra, respectively). Protein tryptophan and vitamin A fluorescence spectra were recorded directly on cheese samples. Considering tryptophan fluorescence spectra, a good classification was observed for 76.4 and 63.5% of the calibration and the validation samples, respectively. A better classification was obtained from the vitamin A fluorescence spectra since 93.9 and 90.5% of the calibration and validation spectra, respectively, were correctly classified. Cheeses from Finland and Denmark were well separated using the 1500-900 cm -1 spectra and tryptophan or vitamin A fluorescence spectra. Considering cheeses from Germany, 100% of good classification was only obtained with vitamin A spectra. Cheeses from France and Switzerland were generally discriminated, but several samples were incorrectly classified. It was concluded that vitamin A fluorescence spectra may be considered a promising probe for the reliable evaluation of Emmental cheese origin.Emmental cheese / geographic origin / authenticity / infrared / fluorescence / chemometry Résumé -Les spectroscopies infrarouge et de fluorescence frontale : un outil pour la détermi-nation de l'origine géographique des fromages Emmental de productions estivales.

The stable isotope ratios ( 13 C/ 12 C, 15 Recently, several papers have been published about the application of stable isotope ratio analysis (SIRA) using isotopic ratio mass spectrometry (IRMS) to animal products. The aims of these studies were to obtain dietary reconstruction, to study animal movement patterns, 1-5 and to characterise the geographical origin. [6][7][8][9][10][11][12][13][14][15][16] Another important aim could be to study and quantify the alteration of stable isotope ratios (SIRs) in milk by substituting a C 3 plant diet with maize. This could be important in order to protect milk and milk derivatives produced using traditional or 'organic' practices of pasture compared with products produced with cheaper diets based on maize derivatives. There have been recent reports about this in defatted meat, [17][18][19] in related fat, 17 in several animal tissues such as blood, plasma, liver, kidney, cow hair 20 and in sheep faeces. 21 In these papers it was shown that there is a strong correlation between the SIR of carbon and the amount of maize in the diet. It was also shown that the degree of this alteration depends on the component or body tissue considered, due to its biochemical composition and turnover rate. 22 On the other hand, variations in the SIRs in milk and milk derivatives following suitable experimental design have not been so extensively explored. Metges et al. 23 investigated the 13 C/ 12 C of CO 2 breath, bulk milk and serum by exchanging a C 3 plant with a C 4 plant diet, and vice versa. Wilson et al. 24 studied the contribution of body protein to milk protein, changing abruptly from a C 3 to a C 4 diet. More recently, Knobbe et al. 25 followed the variation in stable carbon and nitrogen isotopic composition under different feeding regimes. It was concluded that, to obtain more detailed information on the influencing factors, the analysis of the SIRs of other elements such as oxygen and hydrogen may be necessary.In this study we considered around 130 cows stabled in two farms and supplied with diets made up of different kinds of C 3 plants and different amounts of maize. The different feed ingredients, the overall diet and the relevant milk (casein, lipid and some bulk samples) were subjected to analysis of 13
