“…However, this is not the case with cultivar protected under geographical denominations commercialised in purity by the industry such as 'Tonda Gentile' productions. Lang et al [23] were able to separate European cultivars from Georgian and Azerbaijan cultivars, with Turkish ones showing an ambiguous behaviour, based on polymorphic variations in the chloroplast genome.…”

The request for an efficient traceability system able to identify hazelnut cultivars along the entire processing chain is becoming a critical point for avoiding fraudulent practices and safeguarding the interests of growers, food processors and consumers. In this study, DNA was extracted from different hazelnut matrices, including plant material (leaf, kernel and kernel episperm), and processed foods (paste, grain, flour and different types of snacks containing hazelnuts). The efficiency of Simple Sequence Repeat (SSR) markers was tested to identify the hazelnut cultivar ‘Tonda Gentile’ in all the supply chain. The analysis at 10 SSR loci was able to verify the presence/absence of the alleles of a declared cultivar contained in these matrices. The SSR analysis of DNA from raw episperm offers the possibility of identifying the mother cultivar and is suggested as an effective way to discover frauds since DNA analysis can be performed on individual kernels. For food matrices containing hazelnuts, the presence of the mother cultivar’s DNA can be assessed based on the identification of its alleles in the sample, although the presence of multiple alleles from the pollenizers makes the interpretation of results more difficult.

“…At present, there are few references concerning the genetic traceability of hazelnut-based processed food [22,23]. Cultivar identification using DNA markers in hazelnut is critical since the edible part is the seed.…”

“…The putative candidate genes identified in this work could be useful for enhancing the shelf life of dessert-type cantaloupe melons. CE methodologies applied to DNA analysis reported in the last 2 years have been aimed at assessing food safety [57][58][59], detecting genetically modified organisms (GMOs) [60,61], evaluating food authenticity [62,63], and detecting food fraud [64,65].…”

This work presents a revision of the main applications of capillary electromigration (CE) methods in food analysis and Foodomics. Papers that were published during the period March 2021 to March 2023 are included. The work shows the multiple CE methods that have been developed and applied to analyze different types of molecules in foods and beverages. Namely, CE methods have been applied to analyze amino acids, biogenic amines, heterocyclic amines, peptides, proteins, phenols, polyphenols, pigments, lipids, carbohydrates, vitamins, DNAs, contaminants, toxins, pesticides, additives, residues, small organic and inorganic compounds, and other minor compounds. In addition, new CE procedures to perform chiral separation and for evaluating the effects of food processing as well as the last developments of microchip CE and new applications in Foodomics will be also discussed. The new procedures of CE to investigate food quality and safety, nutritional value, storage, and bioactivity are also included in the present review work.
