“…More recently, 1 H NMR spectra of traded cocoa beans were used to characterise fermented cocoa beans on the basis of the variety and geographical origin. [15,16] H, C, N, O and S stable isotope ratios measured using Isotope Ratio Mass Spectrometry (IRMS) have been shown to be a reliable tool for establishing the authenticity of a wide variety of food products, such as wine, [17] olive [18] and sesame oils, [19] orange juice, [20] honey, [21] beef, [22] fish, [23,24] shrimps [25] and prawns, [26] ham, [27] milk, [28] rice, [29] lentils. [30] This is due to particular isotopic fractionation processes, which reflect both climatic phenomena (e.g.…”

The isotopic profile (δ(13) C, δ(15) N, δ(18) O, δ(2) H, δ(34) S) was used to characterise a wide selection of cocoa beans from different renowned production areas (Africa, Asia, Central and South America). The factors most influencing the isotopic signatures of cocoa beans were climate and altitude for δ(13) C and the isotopic composition of precipitation water for δ(18) O and δ(2) H, whereas δ(15) N and δ(34) S were primarily affected by geology and fertilisation practises. Multi-isotopic analysis was shown to be sufficiently effective in determining the geographical origin of cocoa beans, and combining it with Canonical Discriminant Analysis led to more than 80% of samples being correctly reclassified.

“…Stable isotope and FA analyses are considered as effective methods to trace seafood products, such as fishes, shrimp, and sea cucumber . With the rapid development of commercial squid products, effective approaches aimed to track processed squid are needed.…”

“…1.5 mg of samples was added to a tin capsule prior to analysis. For carbon stable isotope analysis, lipids were extracted from the samples before analysis because lipids are depleted in 13 C relative to proteins and carbohydrates and the lipid concentration in muscle may vary between individuals . To accomplish this, we collected the solid residues from which lipids had been removed for FA analysis.…”

“…DNA analysis is also widely used to classify the origin of seafood, although low genetic diversity has been reported among population units within D. giga s . Biochemical tracers, such as fatty acid (FA) profiles and stable isotope ratios, have proven to be powerful indicators to identify the geographic origin of food products . FAs are an important energy source for the growth and survival of marine organisms, and regional differences in FA profiles have been reported at the intraspecific level .…”

“…In previous studies, the stable isotope analysis was successfully used to study the geographic origin of aquaculture species: e.g. apparent difference in the δ 13 C and δ 15 N ratios of mackerel, yellow croaker and pollock were observed with respect to country of origin (Kim, Suresh Kumar & Shin, ). In the present study, the shrimp collected in the United States and China could not be differentiated by this method.…”

Increasing numbers of mislabelled seafood products in the globalized market underline the need for approaches to identify the origin of these products. Pacific white shrimp cultured in different salinities (Litopenaeus vannamei) from 16 locations in China and USA were collected and differentiated based on d 13 C and d 15 N values. The d 13 C and d 15 N values of 16 commercial feeds used in shrimp culture were measured and effects of feed on C and N stable isotope composition in shrimp were investigated. Carbon and nitrogen isotopic analysis of the shrimp did not provide means to discriminate farmed shrimp from China and USA. However, the shrimp cultured in water with high salinity were enriched in 13 C compared to shrimp cultured in freshwater and this provided another basis for discrimination. The correlation between d 13 C in feed and shrimp was not significant, while the d 15 N in feed and shrimp showed a trend of positive correlation.
