Mitigation of enniatins in edible fish tissues by thermal processes and identification of degradation products.
2017
Emerging mycotoxins, such as enniatins and beauvericin, are common contaminants in vegetal matrices, but recently, the occurrence of mycotoxins in foodstuffs from animal origin has been also reported as they can be present in edible tissues of animals fed with contaminated feedstuffs. Sea bass, sea bream, Atlantic salmon and rainbow trout from aquaculture analyzed in the present survey showed contamination by emerging Fusarium mycotoxins enniatins (ENs). ENs were extracted from raw and cooked fish with acetonitrile and analyzed by Liquid Chromatography coupled to Mass Spectrometry. In this study, the stability of ENs was evaluated during food processing by the application of different cooki…
Occurrence, toxicity, bioaccessibility and mitigation strategies of beauvericin, a minor Fusarium mycotoxin.
2017
Emerging Fusarium mycotoxins include the toxic secondary metabolites fusaproliferin, enniatins, beauvericin (BEA), and moniliform. BEA is produced by some entomo- and phytopathogenic Fusarium species and occurs naturally on corn and corn-based foods and feeds infected by Fusarium spp. BEA has shown various biological activities (antibacterial, antifungal, and insecticidal) and possesses toxic activity, including the induction of apoptosis, increase cytoplasmic calcium concentration and lead to DNA fragmentation in mammalian cell lines. Cereals food processing has an important effect on mycotoxin stability, leading to less-contaminated food compared to the raw materials. Different industrial…

Sustainability for Food Consumers: Which Perception?
2019
A sustainable future for the community is one of the objectives established by the European Union Agenda 2030. Furthermore, sustainable consumption has been identified as one of the possible trajectories for sustainable development. It is for this reason that food production, distribution and consumption ways cannot be overlooked for sustainability achievement, as well as the consumer&rsquo
Foreste a tavola:i consumi alimentari inducono la crescente deforestazione tropicale e sub-tropicale anche in Italia
2021
L’agricoltura costituisce da sempre una grande minaccia per gli ecosistemi naturali del nostro pianeta,e non solo in quanto attività umana essenziale per la produzione di cibo. Attualmente, in particolarenella regione tropicale e sub-tropicale, le attività agricole sono fattori di pressione cruciali per il mantenimentodei cicli di vita di ecosistemi essenziali per la biosfera, complessi e resilienti, come le foreste. Lesocietà contemporanee, essenzialmente urbane e sempre più disconnesse dai processi naturali ed ecologici,tendono a dimenticare, o semplicemente non considerare, le responsabilità di queste pressioni insostenibili.Tra le maggiori cause di deforestazione, quattro commodities ri…
European Politics of Food Origin. A Semiotic Analysis of Geographical Indications
2021
This chapter investigates the relationship between food products and origin places within the European Union food policies. In the 1990s, the EU established a Geographical Indication (GI) system, constituted of a set of food quality brands and a legal framework for food, wine and spirits. This system, defined as a sui generis model by insiders, entails a strong EU government participation in the typical food symbolic and material modelling. The sui generis model establishes a government monopoly on the place-based labels registration and institutes an atypical kind of intellectual property based on geographic marks. By proposing a semiotic approach toward the analysis of European Geographic…
Food Processing and Foodborne Illness
2015
Food processing means manipulation of raw materials from plants or animals into food. Since agriculture and animal husbandry were established postharvest procedures were necessary to preserve for a longer time the increasing food supplies coming from the fields and domesticated animals. Food is one of the best culture medium for a lot of microorganisms and preventing food spoilage caused by enzymes and microorganisms is crucial. Deterioration of food is caused mainly by three natural processes: 1. Oxidation – vegetables after harvesting or meat after animal slaughtering get in contact with the oxygen in the air that makes them rancid and unpleasant. 2. Enzyme action – all food contains natu…
Detection of Invisible Damages in ‘Rojo Brillante’ Persimmon Fruit at Different Stages Using Hyperspectral Imaging and Chemometrics
2021
[EN] The main cause of flesh browning in 'Rojo Brillante' persimmon fruit is mechanical damage caused during harvesting and packing. Innovation and research on nondestructive techniques to detect this phenomenon in the packing lines are necessary because this type of alteration is often only seen when the final consumer peels the fruit. In this work, we have studied the application of hyperspectral imaging in the range of 450-1040 nm to detect mechanical damage without any external symptoms. The fruit was damaged in a controlled manner. Later, images were acquired before and at 0, 1, 2 and 3 days after damage induction. First, the spectral data captured from the images were analysed through…
Novel Food Processing and Extraction Technologies of High-Added Value Compounds from Plant Materials
2018
Some functional foods contain biologically active compounds (BAC) that can be derived from various biological sources (fruits, vegetables, medicinal plants, wastes, and by-products). Global food markets demand foods from plant materials that are “safe”, “fresh”, “natural”, and with “nutritional value” while processed in sustainable ways. Functional foods commonly incorporate some plant extract(s) rich with BACs produced by conventional extraction. This approach implies negative thermal influences on extraction yield and quality with a large expenditure of organic solvents and energy. On the other hand, sustainable extractions, such as microwav…
Effect of Innovative Food Processing Technologies on the Physicochemical and Nutritional Properties and Quality of Non-Dairy Plant-Based Beverages
2020
Increase in allergenicity towards cow’s milk, lactose intolerance, the prevalence of hypercholesterolemia, and flexitarian choice of food consumption have increased the market for cow’s milk alternatives. Non-dairy plant-based beverages are useful alternatives because of the presence of bioactive components with health-promoting properties, which attract health-conscious consumers. However, the reduced nutritional value and sensory acceptability of the plant-based beverages (such as flavor, taste, and solubility) compared to cow’s milk pose a big threat to its place in the market. Thermal treatments are commonly used to ensure the quality of plant-based beverages during storage. However, th…
