Nutritional and phytochemical profiling of grape by-products: toward high-value...
Souza, Hiléia K. S.; Fernandes, Ana; Magalhães, Daniela; Vilas-Boas, Ana A.; Melo, Adma; Campos, Débora A.; Pintado, ManuelaGrape by-products, generated as solid residues from winemaking, are rich in dietary fiber and phenolic compounds, mainly anthocyanins, offering strong potential for sustainable valorization. Their fiber-dominant composition, moderate protein and lipid content, and high antioxidant capacity make them suitable for applications in functional ingredients, dietary fiber enrichment, and natural pigment utilization. V...
Flavonoid-rich extracts from lemon and orange by-products: microencapsulation a...
Dellapina, Giovanna; Poli, Giovanna; Moscatelli, Vanna; Magalhães, Daniela; Vilas-Boas, Ana A.; Pintado, ManuelaCitrus by-products are increasingly recognized as a valuable source of bioactive compounds (BCs), particularly flavonoids. Their incorporation into food matrices as functional ingredients aligns with sustainability goals and consumer demand for health-promoting products. However, challenges such as poor stability and undesirable sensory properties limit their direct use in food systems. This study aimed to deve...
From waste to bioactives: green extraction of natural antioxidants and antimicr...
Fernandes, Ana; Magalhães, Daniela; Souza, Hiléia K. S.; Campos, Débora A.; Boas, Ana A. Vilas; Pintado, ManuelaBackground: Global tomato production reached 192 million tons in 2023. Industrial processing generates around 25% by-products (peels, seeds, pulp), often discarded, yet rich in phenolics (e.g. quercetin, lutein), carotenoids (e.g. lycopene, ?-carotene), fiber and proteins. With growing demand for sustainable, biodegradable, and clean-label packaging materials, there is increasing interest in using natural bioac...
Lemon dietary fibre-based powder as a promising ingredient for the food industr...
Magalhães, Daniela; Rodrigues, Cristina V.; Botella-Martinez, Carmen; Muñoz-Tebar, Nuria; Pérez-Álvarez, José Angel; Viuda-Martos, ManuelLemon co-products are valuable due to their high dietary fibre, making them significant for valorisation. This research aimed to characterise an innovative lemon dietary fibre (LDF) obtained through integrated extraction (of essential oil, phenolic compounds (PCs), and pectin) by evaluating its chemical, physicochemical, structural, techno-functional, total phenolic content, and antioxidant and antibacterial pr...
Lemon co-products as functional ingredients for mortadella reformulation: impac...
Magalhães, Daniela; Bas, Clara Muñoz; Viuda-Martos, M.; Pérez-Álvarez, J. A.; Teixeira, Paula; Pintado, ManuelaHigh consumption of processed meats is associated with higher intakes of refined sugars, sodium, and fats, and lower intakes of phytochemicals and dietary fibres, prompting a search for healthier processed foods. Lemon by-products, which account for up to 50 % of lemon production, are rich in bioactive compounds and represent a promising functional ingredient. This study examined the effects of incorporating le...
Upcycled orange peel ingredients: a scoping review on phytochemical composition...
Vilas-Boas, Ana A.; Magalhães, Daniela; Gómez-García, Ricardo; Campos, Débora A.; Correia, Marta; Pintado, ManuelaBackground/Objectives: Orange peels (OP), a major by-product of the juice industry, are rich in bioactive compounds (phenolic compounds, pectin, carotenoids, and essential oils). Its valorization represents a promising route to reduce food waste and foster a circular bioeconomy. This review aimed to map scientific progress in OP upcycling, focusing on the extraction of bioactive ingredients for human nutrition ...

Souza, Hiléia K. S.; Fernandes, Ana; Magalhães, Daniela; Vilas-Boas, Ana A.; Melo, Adma; Campos, Débora A.; Pintado, ManuelaGrape by-products, such as skins and seeds generated during winemaking, represent a valuable source of bioactive compounds and dietary fiber. These residues are rich in phenolics—particularly anthocyanins—with recognized antioxidant, antimicrobial, and anti-inflammatory activities. Their valorization aligns with circular economy principles, promoting waste reduction and the development of sustainable ingredient...
Unlocking the potential of lemon by-products as functional ingredients: an oppo...
Magalhães, Daniela; Viuda-Martos, M.; Pérez-Álvarez, J. A.; Teixeira, Paula; Pintado, ManuelaIntroduction: Citrus fruits are one of the most widely cultivated fruit crops and one of the most important products consumed in the Mediterranean region. The annual production of different types of citrus fruits was around 143 thousand tonnes in 2019, with lemons and limes accounting for around 20 thousand tonnes [1]. Industrial processes use only 45% of the total weight of the fruit, leaving a significant amo...

Natural pigments recovery from food by-products: health benefits towards the fo...
Magalhães, Daniela; Gonçalves, Ricardo; Rodrigues, Cristina V.; Rocha, Helena R.; Pintado, Manuela; Coelho, Marta C.Given the health risks associated with synthetic colorants, natural pigments have emerged as a promising alternative. These renewable choices not only provide health benefits but also offer valuable technical and sensory properties to food systems. The effective application of natural colorants, however, requires the optimization of processing conditions, exploration of new sources, and development of novel for...
