Summary: This review focuses on the current research status of authenticity and geographical origin traceability of animal-derived food. It covers various aspects such as geographical origin, feeding ingredients, adulteration of substitutes, and physical and chemical properties. Stable isotope ratio analysis and element analysis are commonly used traceability techniques, while spectroscopic techniques have the advantages of quick response, low cost, and non-destructiveness. Instrument technology combined with chemometrics is the key method for origin traceability and authenticity. There is also a new trend of origin traceability through analyzing inedible parts of animal-derived food. Understanding the authenticity and geographical origin traceability of animal-derived food is of great importance for food safety.

Summary: In this study, a method using GC-C-IRMS analysis and pre-column derivatization was developed to determine the 815N stable ratio of SEM in shrimp and crab. The results showed that the 815N values of SEM significantly decreased after the use of nitrofurazone. Furthermore, the analysis of SEM in crustaceans indicated a significant difference between SEMex and SEMend, which can be used for determining the source of SEM in vivo.

Summary: Authentication of vegan and vegetarian foods is crucial due to the possibility of adulteration with cheap meat. This study identified nine marker peptides using LC-MS/MS for meat detection. These marker peptides successfully differentiated between beef and milk, as well as chicken meat and egg in 19 commercial vegetarian substitutes. Further testing confirmed the presence of these markers in mammals and poultry, and their absence in plant-based ingredients.

Summary: Stable isotope and multi-element analytical techniques with chemometrics were used to trace the origin authenticity of rice in China market. A total of 115 batches of rice samples from 8 main producing areas of 7 Asian countries were analyzed. Supervised multivariate modeling methods like PLS-DA and LDA showed higher accuracy in identifying rice origins compared to ANOVA and unsupervised methods. δ2H, δ13C, Ba, Al, Mg, δ34S, Pb, and δ18O were identified as important variables for rice origin traceability. This analytical strategy can help ensure the authenticity of rice origin and combat mislabeling in rice trade.

Summary: In this study, a HS-GC-IMS method was used to authenticate laboratory-made quinoa flour adulteration with wheat and rice flours. Through the analysis of volatile compounds, pure and adulterated quinoa flours with different proportions could be easily distinguished, and specific volatile compounds were proposed as markers for authentication. The HS-GC-IMS method was confirmed to be an effective method for adulteration detection.

Summary: This study aimed to authenticate 26 tea samples by combining inorganic chemical tracers (multi-elements and Sr isotopy) with volatile organic compound (VOCs) to discriminate the geographic origin, the varieties and transformation processes. By measuring Sr isotope ratio using MC-ICP-MS, 6 out of 11 regions were successfully discriminated. The combination with ICP-MS inorganic pattern allowed to discriminate 4 more regions with a significance level of 0.05. VOCs fingerprints obtained with SIFT-MS were not correlated with origin but with the cultivar and transformation processes. Green, oolong, and dark teas were clearly differentiated, with hexanal and hexanol contributing to the discrimination of oxidation levels.

Summary: This study highlights the limitations of the current origin labeling system for non-soil-based agricultural products, particularly mushrooms. A new origin identification model based on stable isotope ratio analysis is proposed to accurately determine the geographical origin of shiitake mushrooms, with a high classification sensitivity and overall accuracy. This suggests the need for revising the current labeling system to ensure fair trade and prevent mislabeling in the global shiitake market.

Summary: This study investigated the efficiency of eucalyptus oil as a safer solvent to extract polycyclic aromatic hydrocarbons from soil and sediment. Optimization of extraction conditions and evaluation of desorption kinetics were performed. Results showed that eucalyptus oil had higher extraction efficiency from soil than sediment, and it had the potential to extract hydrophobic contaminants with good recovery rates and low detection and quantitation limits.

Summary: This study evaluated the potential for biosurfactant-mediated desorption of polyaromatic hydrocarbons (PAHs) and investigated the desorption efficiency and toxicity of novel biosurfactants. The results showed that sophorolipid and saponin were effective in removing PAHs, with sophorolipid being more efficient for low molecular weight PAHs in soil and sediment. Additionally, these biosurfactants showed no toxicity to the soil/sediment microbiome, suggesting that they can be sustainable approaches for PAH removal.

Summary: This study examines the dynamics of fumonisins during winemaking and storage and the role of fining agents in the removal of FB2, the most prevalent fumonisin produced by black aspergilli. The results show that vinification can lead to the partial removal of fumonisins, and the use of fining agents and wine storage can further reduce fumonisin contamination.

Summary: This study compared the extraction efficiency of polycyclic aromatic hydrocarbons (PAHs) from soil and sediment using supercritical fluid extraction (SFE) with ethanol as the modifier, microwave-assisted extraction (MAE), and eucalyptus oil-assisted extraction (EuAE). The recoveries of PAHs were similar among the three methods, with over 80% recovery for pyrene, chrysene, and benzo[a]pyrene. SFE was found to be the most efficient method for extracting PAHs from naturally incurred soils. EuAE required a longer extraction time but lower temperatures and less solvent compared to SFE and MAE. Compared to MAE, SFE and EuAE are more sustainable approaches for PAH extraction.

Summary: The potential toxic effects of sophorolipid and eucalyptus saponin biosurfactants on bioremediation of PAH-contaminated soils and sediments were studied. Germination assays showed that both saponin and sophorolipid had non-phytotoxic effects, while rhamnolipid had greater phytotoxicity. The presence of saponin and sophorolipid also influenced the bacterial diversity and structure in soil, but not in sediment samples.

Summary: Acacia implexa, Eucalyptus rossii and Exocarpos cupressiformis are native Australian plants used medicinally by the indigenous people. This study extracted crude extracts from the bark and leaves of A. implexa, the leaves of E. rossii, and the leaves of E. cupressiformis using 70% aqueous ethanol. The extracts were then fractionated and tested for their antioxidant activity using various assays. The lipid-based assay showed that the non-polar fractions had higher antioxidant activity, which was missed by the aqueous assays. Gallic acid, (+)-catechin, (-)-epicatechin, and tannins were identified as potential antioxidant compounds.
