- A comprehensive review on carotenoids in foods and feeds: status quo, applications, patents, and research needsPublication . Meléndez-Martínez, A.J.; Mandić, A.I.; Bantis, F.; Böhm, V.; Borge, G.I.A.; Brnčić, M.; Bysted, A.; Cano, M.P.; Dias, M.G.; Elgersma, A.; Fikselová, M.; García-Alonso, J.; Giuffrida, D.; Gonçalves, V.S.S.; Hornero-Méndez, D.; Kljak, K.; Lavelli, V.; Manganaris, G.A.; Mapelli-Brahm, P.; Marounek, M.; Olmedilla-Alonso, B.; Periago-Castón, M.J.; Pintea, A.; Sheehan, J.J.; Tumbas Šaponjac, V.; Valšíková-Frey, M.; Meulebroek, L.V.; O'Brien, N.Carotenoids are isoprenoids widely distributed in foods that have been always part of the diet of humans. Unlike the other so-called food bioactives, some carotenoids can be converted into retinoids exhibiting vitamin A activity, which is essential for humans. Furthermore, they are much more versatile as they are relevant in foods not only as sources of vitamin A, but also as natural pigments, antioxidants, and health-promoting compounds. Lately, they are also attracting interest in the context of nutricosmetics, as they have been shown to provide cosmetic benefits when ingested in appropriate amounts. In this work, resulting from the collaborative work of participants of the COST Action European network to advance carotenoid research and applications in agro-food and health (EUROCAROTEN, www.eurocaroten.eu, https://www.cost.eu/actions/CA15136/#tabs|Name:overview) research on carotenoids in foods and feeds is thoroughly reviewed covering aspects such as analysis, carotenoid food sources, carotenoid databases, effect of processing and storage conditions, new trends in carotenoid extraction, daily intakes, use as human, and feed additives are addressed. Furthermore, classical and recent patents regarding the obtaining and formulation of carotenoids for several purposes are pinpointed and briefly discussed. Lastly, emerging research lines as well as research needs are highlighted.
- A conceptual framework for the collection of food products in a Total Diet StudyPublication . Turrini, A.; Lombardi-Boccia, G.; Aureli, F.; Cubadda, F.; D'Addezio, L.; D'Amato, M.; D'Evoli, L.; Darnerud, P.; Devlin, N.; Dias, M.G.; Jurković, M.; Kelleher, C.; Le Donne, C.; López Esteban, M.; Lucarini, M.; Martinez Burgos, M.; Martínez-Victoria, E.; McNulty, B.; Mistura, L.; Nugent, A.; Oktay Basegmez, H.; Oliveira, L.; Ozer, H.; Perelló, G.; Pite, M.; Presser, K.; Sokolić, D.; Vasco, E.; Volatier, J.L.A total diet study (TDS) provides representative and realistic data for assessing the dietary intake of chemicals, such as contaminants and residues, and nutrients, at a population level. Reproducing the diet through collection of customarily consumed foods and their preparation as habitually eaten is crucial to ensure representativeness, i.e., all relevant foods are included and all potential dietary sources of the substances investigated are captured. Having this in mind, a conceptual framework for building a relevant food-shopping list was developed as a research task in the European Union's 7th Framework Program project, 'Total Diet Study Exposure' (TDS-Exposure), aimed at standardising methods for food sampling, analyses, exposure assessment calculations and modelling, priority foods, and selection of chemical contaminants. A stepwise approach following the knowledge translation (KT) model for concept analysis is proposed to set up a general protocol for the collection of food products in a TDS in terms of steps (characterisation of the food list, development of the food-shopping list, food products collection) and pillars (background documentation, procedures, and tools). A simple model for structuring the information in a way to support the implementation of the process, by presenting relevant datasets, forms to store inherent information, and folders to record the results is also proposed. Reproducibility of the process and possibility to exploit the gathered information are two main features of such a system for future applications.

- Establishing an EFSA open-access European Food Composition Database (EU FCDB) in EuropePublication . Finglas, P.; Roe, M.; Astley, S.; Kadvan, A.; Milesevic, J.; Costa, H.S.; Dias, M.G.; Toxopeu, I.; Livaniou, A.; Presser, K.; Czack, J.; Reinivuo, H.Background and objectives: The establishment of an EFSA (European Food Safety Authority) open-access European food composition database (EU FCDB) represents a critical advancement in standardising and harmonising food composition data across Europe. The EFSA EU FCDB aims to provide high-quality, comprehensive, and regularly updated nutritional data to support public health policies, dietary assessments, food safety regulations, and risk assessments. By offering a centralised and scientifically robust resource, supported by national compilers, it ensures consistency in nutrient data across Member States and enhances the accuracy of dietary intake evaluations. It also fosters cooperation between EFSA, international networks, and data users. Methods: Key components include the integration of sixteen national food composition datasets in Europe, adherence to standardised methodologies for data collection and quality assurance, and incorporation of analytical, calculated, and estimated values for the nutrient content of key foods, fortified products, and dietary supplements. Addressing challenges in data completeness and consistency has necessitated use of validated recipe calculations, yield and retention factors, and imputation methods for missing values. Additionally, the project advocates for identification and prioritisation of key foods, ensuring representation of the most nutritionally significant foods. Expanding food classification coverage is also vital to accommodate emerging trends such as plant-based diets, reformulated products, novel food sources, and other datasets such as those describing climate impact of foods and food systems. Results: Technical solutions for data submission, retrieval, and interoperability are fundamental for success. Recommendations include implementing standardised data formats using FoodEx2, developing automated validation and harmonisation, and providing mechanisms for downloading. These improvements will support stakeholders by enabling integration of data into dietary monitoring tools, risk assessment models, and public health surveillance systems. Conclusions: The EFSA EU FCDB will serve as a pivotal resource for researchers, policymakers, public health authorities, and industry professionals, facilitating evidence-based decisionmaking, nutrition policy development, and consumer education. By fostering data transparency, accessibility, and methodological rigor, this database can significantly enhance the accuracy of dietary intake assessments and contribute to improved nutritional monitoring, food safety measures, and public health outcomes across Europe.
