Special Issue Information

Dear Colleagues,

In recent years, the problem of food adulteration has become increasingly rampant, seriously hindering the development of food production, consumption, and management.  Species fraud, dilution, substitution, unapproved enhancement, counterfeit, and origin mislabeling represent various forms of common food frauds. At present, numerous technologies, such as electronic label technology, chemical analysis methods, and biological identification methods, are employed in the study of food authenticity. The objects of food authenticity analysis include primary agricultural products, processed products and the key ingredients of food. Currently, rapid and efficient analysis technology is a primary development trend in the field of food authenticity. Spectroscopic technology, ambient ionization mass spectrometry, electronic sensors, and DNA-based technology have gradually been applied in the field of food authenticity due their rapid analysis speed and simple operation.

Considering the above, we invite researchers to submit their unpublished original manuscripts focusing on food authenticity and traceability. The subjects addressed by this Special Issue include, but are not limited to, the following:

  • Analytical solutions (targeted and untargeted methods) for food authenticity and traceability;
  • Food fingerprinting;
  • Detection of undeclared novel ingredients in foods;
  • Multi-methods approaches and data fusion;
  • Molecular analysis and biotechnological solutions (immunochemistry; PCR-related techniques; nucleic acids probes; micro- and nanosensors, MEMS);
  • Advanced statistical methods, post-analytical processing, artificial intelligence-based methods, and machine learning;
  • Information technologies such as Blockchain, coupled with analytical approaches.

Developing a fast and non-destructive methodology to identify the storage years of Coix seed is important in safeguarding consumer well-being. This study employed the utilization of hyperspectral imaging (HSI) in conjunction with conventional machine learning techniques such as support vector machines (SVM), k-nearest neighbors (KNN), random forest (RF), extreme gradient boosting (XGBoost), as well as the deep learning method of residual neural network (ResNet), to establish identification models for Coix seed samples from different storage years. Under the fusion-based modeling approach, the model’s classification accuracy surpasses that of visible to near infrared (VNIR) and short-wave infrared (SWIR) spectral modeling individually. The classification accuracy of the ResNet model and SVM exceeds that of other conventional machine learning models (KNN, RF, and XGBoost). Redundant variables were further diminished through competitive adaptive reweighted sampling feature wavelength screening, which had less impact on the model’s accuracy. Upon validating the model’s performance using an external validation set, the ResNet model yielded more satisfactory outcomes, exhibiting recognition accuracy exceeding 85%. In conclusion, the comprehensive results demonstrate that the integration of deep learning with HSI techniques effectively distinguishes Coix seed samples from different storage years. Full article

Verifying the geographical origin of soybeans (Glycine max [Linn.] Merr.) is a major challenge as there is little available information regarding non-parametric statistical origin approaches for Chinese domestic and imported soybeans. Commercially procured soybean samples from China (n = 33) and soybeans imported from Brazil (n = 90), the United States of America (n = 6), and Argentina (n = 27) were collected to characterize different producing origins using stable isotopes (δ2H, δ18O, δ15N, δ13C, and δ34S), non-metallic element content (% N, % C, and % S), and 23 mineral elements. Chemometric techniques such as principal component analysis (PCA), linear discriminant analysis (LDA), and BP–artificial neural network (BP-ANN) were applied to classify each origin profile. The feasibility of stable isotopes and elemental analysis combined with chemometrics as a discrimination tool to determine the geographical origin of soybeans was evaluated, and origin traceability models were developed. A PCA model indicated that origin discriminant separation was possible between the four soybean origins. Soybean mineral element content was found to be more indicative of origin than stable isotopes or non-metallic element contents. A comparison of two chemometric discriminant models, LDA and BP-ANN, showed both achieved an overall accuracy of 100% for testing and training sets when using a combined isotope and elemental approach. Our findings elucidate the importance of a combined approach in developing a reliable origin labeling method for domestic and imported soybeans in China. Full article
