Food traceability

Over the last decades, food safety has been a growing concern all over the world. Traceability systems are considered as the main tools for eliminating the concerns of consumers, manufacturers, and legal authorities on food safety. Considering that, different types of techniques have been developed for the food industry to enable proper traceability. In this chapter, traceability techniques including document-based systems, information and communication technologies, alphanumerical codes, barcodes, holograms, radio-frequency identification, nuclear techniques, and nanotechnology are discussed in details. In addition, the major analysis methods that are used in food traceability, which include immunoassays, DNA-polymerase chain reaction methods, omics, and isotope ratio analysis, are highlighted.
