Full textViene studiata l'applicabilità della sistematica isotopica dello Sr alla qualificazione e alla tracciabilità di origine geografica di prodotti vitivinicoli, in questo caso il Prosecco veneto DOC. Vengono caratterizzati campioni di uva provenienti da dieci diversi vigneti e delle vendemmie 2010, 2011 e 2012, oltre ai campioni di suolo corrispondenti. Vengono usati anche i dati di chimismo di suoli ed uve al fine di comprendere meglio i complessi equilibri nel sistema pianta-acqua-suolo. Si osserva che i campioni possono essere differenziati sia in funzione della localizzazione geografica che secondo l'anno di vendemmia. Le variazioni geografiche vengono attribuite alla diversa geologia dei siti, le variazioni annuali agli apporti atmosferici e/o antropici di Sr. Si osserva una correlazione positiva tra composizione isotopica dell'uva e quella della frazione labile del suolo corrispondente, permettendo una modellazione di massima, consistente nella previsione del valore dell'uva a partire da quello del suolo. Le diverse componenti dell'uva (bucce, succo, semi e raspo) risultano avere composizioni isotopiche sovrapponibili, confermando l'assenza di frazionamento isotopico. La sistematica isotopica dello Sr si conferma come buona tecnica da applicare a problemi di caratterizzazione e tracciabilità, possibilmente in un contesto multivariabile. Ciò nonostante, le dinamiche presenti tra suolo e biosfera sono molto complesse e variabili, e questo si traduce spesso in elevati margini di errore di cui bisogna tenere conto durante le modellazioni e le conclusioni.

Full textThe thesis is organized according to the different experiments. The first chapter focus on genetic characterisation of 28 local maize populations. The analysis assessed the conservation status of the accessions and allowed the construction of a phylogenetic tree to identify the relationships existing between the different varieties. The possibility to use a molecular marker based traceability approach was evaluated on a smaller number of maize accession. This analysis focused on maize flour for direct human consumption. The second part is an example of food traceability along the cocoa-chocolate chain. The use of molecular markers allowed the identification of the genetic of the CCN51 cultivar (clone) allowing the discrimination between CCN51 and the 'National' variety (population). The identification and traceability of “pure” CCN51 cocoa batches is possible following this approach. The third chapter focused on wine production chain with the aim of the optimisation of methodologies for DNA extraction from grapes and must during the various winemaking steps until pre and post bottling. The obtained DNA was successfully amplified and used for a microsatellite analysis allowing the identification of the grape varieties used for winemaking process.

Full textFood safety and food security are crucial aspects in the growing and constantly changing food market. The first definition refers to hygiene and foodborne diseases prevention, the second refers to the security for a consumer to by a specific product and not a counterfeit. An improved traceability, based on blockchain systems, may help to prevent food safety and food security issues. Blockchain belongs to the distributed ledgers, a type of database in which each participant owns a copy of the same data and every change in a copy is automatically reflected on the other copies. It is designed to guarantee decentralization, transparency, immutability and traceability. As shown by a relevant number of projects that has been developed and applied, it suits to the food supply chain traceability. An improved traceability based on blockchain can also be useful at the market level. For instance, Italian sounding is the practice to use Italian words, colours (such as the Italian flag colours) and names to give an Italian appearance to a product, irrespective of its country of origin and its production method, to promote it. It affects different sectors, but the food sector is the most damaged. The present research is focused on the application of the blockchain to the traceability of the food supply chain, its impacts and its perception. Indeed, the application of these systems may have several advantages, but also negative impacts: the producers must accept to show transparency to the consumers, it may lead to a price increase (as the design and maintenance of a digital traceability systems have a considerable cost) and consumer profiling is an aspect that must be properly discussed. To assess if the Italian consumers may be interested in the use of blockchain traceability for food, a survey has been performed on 500 users. The asked questions concern their interest and knowledge towards traceability, blockchain technology, shopping preferences, the suggestion of food categories (e.g. meat, fish and others) currently requiring an improved traceability. Lastly, the willingness to spend more to buy food provided with digital traceability was evaluated. The results revealed that respondents are generally interested in food traceability, they usually know what blockchain and digital traceability are, they buy food mainly at supermarkets, they are interested in knowing the origin of the food mainly for meat, fish and dairy, they would rather buy a product provided with digital traceability system instead of an unprovided competitor and they consider acceptable a 10-15% cost increase for a digitally traced product. To complete the research, a concrete project/case study has been completely developed in collaboration with the innovative startup Franceschi srl, composed by Saporare and S|Trace. Saporare is an online shop of traditional Italian food and beverages (e.g. balsamic vinegar, honey, olive oil, wine) of small and medium sized producers and each product has a declaration of origin. The products will be traced with S|Trace, a blockchain-based traceability system provided with a web app for data upload, designed to ease the operation for the producers. Saporare acts as the third part in the supply chain, certifying the origin and the security of the products, but without substituting production disciplinaries or food control agencies: this makes the perfect use-case to study the application of the blockchain to the food supply chain. Lastly, considering both costs and complexity of the blockchain, a pipeline facilitating the choice of the right technology has been developed. In particular, the developed pipeline may help to define which type of blockchain could be useful for each food supply chain and when a blockchain could be really effective.

Full textIn the agri-food sector, food frauds are increasing every year and there is a demand from the consumer to better understand food products. A suitable bio-molecular identification and traceability system could be used to assess the quality of raw materials up to the finished food products to guarantee the consumer on the identity of the products purchased. DNA testing is a methodology frequently used in the food field, especially DNA barcoding methodology. However, DNA barcoding technique has some limits in the complex food products analysis. Industrial treatments could alter DNA quality of raw material, therefore this analysis could be challenging to apply. Furthermore, DNA barcoding cannot be applied for multispecies products because is feasible only for monospecies products. Finally, DNA barcoding is time-consuming and expensive. Starting from these limits, the main objective of this PhD project was to identify and test innovative biomolecular analyses for the identity assessment of raw materials and processed food products. Three lines of research have been developed in this PhD thesis. In the first line of research was evaluated whether DNA barcoding can be applied to trace the plant component in food supplements from the starting raw material to the finished processed products. We selected a panel of 64 phytoextracts and intermediate of production obtained through three different extraction methods with different solvents. We sequenced and analysed the sequence variability at DNA barcoding and mini-barcoding marker regions. Phytoextracts obtained through hydroalcoholic treatment, with the lower percentage of ethanol and aqueous processing had a major rate of identification. This study proves that DNA barcoding is a useful tool for some typology of food supplement traceability. A second limit that occurs in the food market is related to multispecies products, because DNA barcoding does not allow to analyse them. In the second line of research we wanted to test DNA metabarcoding to characterize plant declared ingredients or contaminants in five categories of commercial insect-based products. The same approach has been used to assess its sensitivity to cases of contamination and counterfeits in insect flour with low cost (and potentially allergenic) vegetable flours like wheat and soybean. Moreover, also the bacteria profile was evaluated. The DNA metabarcoding analysis revealed a high efficacy as a screening method to identify both plant ingredients and possible adulteration events. Concerning the bacteria profile, our data revealed that some bacteria formed a “core microbiome” characterizing the products depending on the insect, suggesting that a resident microbiota is conserved. In order to evaluate the application of DNA metabarcoding also for herbal teas traceability, we analysed fifteen commercial herbal teas to identify all the species in the products and verify the correspondence with the label. Furthermore, to verify the quantitative ability of DNA-metabarcoding, we created six mocks mixture with different percentages of five species of different matrices both starting from raw material and genomic DNA. For all the samples we tested two different markers. Results showed that not all the species declared on the label was found and we were able to detect some contaminants. The two markers were able to detect different species: some species were detected only by one marker, others only by the other. For future analyses it would be necessary to use both the markers to obtain better results in traceability. In conclusion in this line of research we defined that DNA metabarcoding is a valuable method for food supply chain traceability. The third line of research aimed to create a mock-up for truffle identification using the LAMP technique, an isothermal nucleic acid amplification technique. This low-cost kit allows the identification of the white truffles T.magnatum in a total of 90 minutes.
