Potential of different eighteen grapevine genotypes to produce wines in a hot r...
Caldeira, Ilda; Roque, Rita; Anjos, O.; Lourenço, Sílvia; Deus João de; Damásio, Miguel; Silvestre, JoséA major challenge for the viticulture and oenology sector is to understand the impact of climate change on grapevine agronomic performance and wine quality. Genetic variability offers a key tool for adaptation, as some grape varieties may better withstand changing conditions while maintaining wine quality. As part of the WineClimAdapt research project (PDR2020-101-031010), a study was conducted on the adaptabil...
The interplay of bottle storage and wood ageing technology: Volatile and sensor...
Caldeira, Ilda; Anjos, O.; Vitória, Cláudia; Alves, Sheila Oliveira; Fernandes, Tiago A.; Canas, Sara; Catarino, SofiaWine spirits are typically aged in wooden barrels. Recently, alternative ageing technologies, such as those using wood fragments in wine spirits stored in stainless steel tanks, have been investigated. However, a signifcant lack of information regarding the potential evolution of these beverages after bottling still remains. This study assessed the 12-month evolu tion of aroma in bottled wine spirits aged with ...
Insect-based chitin and chitosan from whole body sources and rearing by-product...
Navarro, P.; Ribeiro, J.C.; Luís, Â.; Domingues, F.; Anjos, O.; Cunha, L.M.Fractionation of edible insects and their rearing by-products can lead to expanded industrial applications and extraction of value-added products. The main goal of this study was to extract chitin and synthesise chitosan from three different insect sources ‒ Tenebrio molitor larvae, adult Acheta domesticus and A. domesticus rearing by-products (legs and wings). Furthermore, the physicochemical, structural, and ...
A revisit of plant food waste along food supply chains: Impacts and perspectives
Gonçalves, Joana; Anjos, O.; Guiné, Raquel P. F.More than one billion tons of the food produced in the world ends up being wasted every year, accounting for about one-third of the food produced globally. For this reason, the problem of food waste management has been the focus of the different actors intervening in the food supply chains, who recognize that food waste has not only environmental but also economic and social impacts. This review focuses on food...
Elemental and nutritional characterisation with vibrational spectroscopy analys...
Mouga, Teresa; Almeida, Mariana M.; Pitacas, F.I.; Rodrigues, A.M.; Vitória, Cláudia; Anjos, O.Macroalgae are rich in bioactive compounds with potential therapeutic applications, including antioxidant, antimicrobial, and nutritional properties. In this study, the biochemical composition of three seaweed species—Ulva sp., Gracilaria multipartita, and Sargassum muticum—was analysed, focusing on their mineral content and macronutrient profile. The ash, protein, fibre, lipid, and carbohydrate contents ranged...
Healthy motivations for food consumption in 16 countries
Guiné, Raquel P. F.; Gonçalves, Joana; Florença, Sofia G.; Manuela Ferreira; Cardoso, Ana Paula; Bartkiene, Elena; Djekić, Ilija; Tarcea, MonicaThere are many factors that can influence people’s attitudes towards healthy eating, including personal nature, sociodemographic influences, and lifestyle. This work investigated to what extent the motivations for healthy food consumption are shaped in individuals from different countries. A questionnaire survey was carried out on a sample of 11,919 participants from 16 countries. The results indicated that the...

Cultural heritage on gastronomic usages of honey: Recipe analysis and cluster s...
Florença, Sofia G.; Ferrão, Ana C.; Costa, Cristina A,; Barroca, Maria João; Silva, Aida; Pedro, Soraia; Anjos, O.; Guiné, Raquel P. F.Honey has been a food product used by humans since immemorial times, both for nutritional and medicinal reasons. Gastronomic recipes contain a great deal of knowledge and cultural heritage, both in the form of traditional ancient recipes as well as innovative and modern recipes. This study intends to investigate the use of honey in gastronomy with the purpose of increasing knowledge regarding the culinary usage...

Unveiling the chemistry and bioactivity of bee products and their derivatives
Anjos, O.; Miguel, Maria GraçaApiculture, or beekeeping, refers to the cultivation and management of honey bees for honey and byproducts, including the extraction, bottling, and sale of hive products such as honey, propolis, royal jelly, bee venom, bee pollen, bee bread and other fermented bee products [1]. Honey is a supersaturated solution or semi-solid natural sweet product produced by both honey bees (Apis subfamily) and stingless bees ...
