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

WYKORZYSTANIE OZNACZEŃ STOSUNKÓW STABILNYCH IZOTOPÓW WYBRANYCH PIERWIASTKÓW W OCENIE AUTENTYCZNOŚCI PRODUKTÓW POCHODZĄCYCH Z UPRAW EKOLOGICZNYCHS t r e s z c z e n i e W artykule przedstawiono stan badań dotyczący stosunków stabilnych izotopów węgla i azotu w różnych artykułach spożywczych (warzywach, owocach, mięsie, mleku), które były produkowane metodami tradycyjnymi i ekologicznymi. Miara ilości ciężkiego i lekkiego izotopu w próbce oznaczana jest jako wartość δ. Na wartość δ WprowadzenieWzrasta zainteresowanie żywnością ekologiczną, uznawaną za bardziej bezpieczną dla zdrowia człowieka [5,12,25]. Produkcja żywności ekologicznej wyklucza moż-liwość stosowania pestycydów i nawozów mineralnych, a dopuszcza stosowanie nawozów organicznych [20]. Poszukuje się więc bardziej nowoczesnych metod umożliwiających sprawdzanie autentyczności produktów żywnościowych deklarowanych jako ekologiczne. Coraz większe zastosowanie zyskują metody bazujące na wyznaczeniu stosunków stałych izotopów pierwiastków w celu m.in. kontroli autentyczności produktów spożywczych, w tym także ich pochodzenia [24]. Wyznaczanie stosunków stabilnych izotopów węgla i azotu w różnych warzywach, mięsie i mleku jest również wykorzystywane do odróżnienia żywności produkowanej w warunkach ekologicznych od produkowanej metodami tradycyjnymi.Mgr inż.

“…1 For example, adulterated honey and juice products [2][3][4] and the geographical origin of meat, 5,6 dairy products, 7,8 wine, 9 and cereal crops 10 can be traced by using natural differences in their carbon, nitrogen, and/or oxygen isotopic compositions. In our previous study, we determined the carbon and nitrogen contents (C and N contents) and the stable carbon, nitrogen, and oxygen isotopic compositions (δ 13 C, δ 15 N, and δ 18 O) of polished rice cultivated in Australia (New South Wales), Japan (12 different cultivation areas), and the USA (California) in order to discriminate the geographical origin of the rice.…”

Characterization of Japanese Polished Rice by Stable Hydrogen Isotope Analysis of Total Fatty Acids for Tracing Regional Origin

We determined the δD values of the total fatty acids of Japanese rice to test the hypothesis that there is a wide variation in the hydrogen isotopic composition (δD) of the total fatty acids of Japanese rice sourced from different growth areas in Japan and to distinguish the minor differences among these growth areas. The δD values showed a wide variation ranging from -216 (Hokkaido) to -183 (Okinawa), indicating a good correlation with the corresponding variations for ambient water (r = 0.63) and mean temperature (r = 0.84). These results suggest that the δD values for the total fatty acids can be representative of the growth environments in Japan.
