Enhancing carob flour (Ceratonia siliqua L.) for by-product utilization in food...
Vilas-Boas, Ana Martins; Brassesco, María Emília; Quintino, Andreia C.; Medronho, Bruno; Vieira, Margarida C.; Brandão, Teresa R. S.The focus on by-product valorization in the food industry, particularly from the carob pod, underscores a commitment to sustainability and resource efficiency. This fruit, sourced from the leguminous evergreen carob tree (Ceratonia siliqua L.), is renowned for its adaptable flavour and nutritional value, in Mediterranean regions such as Portugal. Its production yields significant by-products, presenting environ...

IX PhD Students Meeting in Environment and Agriculture - Book of Abstracts
Laranjo, Marta; Alexandre, Ana; Medronho, Bruno; Eufrázio, Sofia; Marques, Cláudia; Pinto Correia, TeresaDear participants, It is our great pleasure to welcome you to the IX PhD Students Meeting in Environment and Agriculture, held in Évora on the 11th and 12th of December 2024. We have put together a two-day program with the aim of encouraging scientific discussion. This Meeting represents an excellent opportunity for young researchers to exchange ideas and to explore new challenges in research regarding Environm...
Tailored cellulose-based flocculants for microplastics removal: mechanistic ins...
Magalhães, Solange; Norgren, Magnus; Alves, Luís; Medronho, Bruno; Rasteiro, Maria da GraçaThis study explores the performance of novel cellulose-derived sustainable flocculants in the flocculation of different model microplastics (MPs), including polyethylene (PE), polyethylene terephthalate (PET) and polyvinyl chloride (PVC). The influence of key parameters, such as pH, flocculant structure and concentration was evaluated by Laser Diffraction Spectroscopy (LDS) and optical microscopy to access thei...
On the optimization of carob seed peel extraction using aqueous-based acidic sy...
Medronho, Bruno; boutoub, Oumaima; Duarte, Hugo; Aliaño González, María José; Guerra, Rui; Brazio, António; Gonçalves, Sandra; Romano, AnabelaCarob fruit utilization remains limited, with most of their commercial value derived from locust bean gum, which is obtained from seed endosperm. Efficient extraction requires dehusking, which is traditionally performed under harsh conditions. This study aims to develop and optimize a milder, more sustainable dehusking method while preserving seed quality for industrial applications. Various aqueous-based solve...
Valorization of arbutus unedo L. Pomace: exploring the recovery of bioactive ph...
Lorenzo, Ritamaria Di; Ferraro, Maria Grazia; Carrera, Ceferino; Iazzetti, Federica; Chinchilla, Nuria; Maisto, Maria; Aliaño González, María JoséThis study explores the potential of Arbutus unedo L. pomace, a by-product of the food industry, as a natural ingredient for skincare applications. In Portugal, A. unedo L. fruits are traditionally used to produce "Aguardente de Medronho", a spirit with a protected geographical indication. The distillation process generates pomace, comprising skins, pulp remnants, seeds, and residual alcohol rich in phenolic co...
Effect of chitosan properties and dissolution state on solution rheology and fi...
Araújo, Francisca; Magalhães, Solange; Medronho, Bruno; Eivazi, Alireza; Dahlström, Christina; Norgren, Magnus; Alves, LuísChitosan films with potential application in triboelectric nanogenerators (TENGs) represent a promising approach to replace non-biobased materials in these innovative devices. In the present work, chitosan with varying molecular weights (MW) and degrees of deacetylation was dissolved in aqueous acetic acid (AA) at different acid concentrations. It was observed that the MW had a greater influence on the viscosit...
From lignocellulosic residues to protein sources: insights into biomass pre-tre...
Vera dos Anjos, Isabela; Coelho, Natacha; Duarte, Hugo; Proença, Diogo Neves; Duarte, Maria F.; Jorge de Barros, Raúl José; Raposo, SaraWith the global population steadily rising, the demand for sustainable protein sources has become increasingly urgent. Traditional animal- and plant-based proteins face challenges related to scalability, resource efficiency, and environmental impact. In this context, single-cell protein has emerged as a promising alternative. Derived from microorganisms such as algae, bacteria, fungi, and yeast, single-cell pro...
Optimizing lignin cationization: unveiling the impact of reaction conditions th...
Fernandes, Catarina; Gomes, Leandro Cid; Bernin, Diana; Alves, Luís; Rasteiro, Maria Graça; Medronho, Bruno; Varela, CarlaLignin, a natural and abundant biopolymer, holds great potential for cosmetic applications. However, its limited solubility and inherently negative charge restrict its use in certain formulations. This is particularly relevant for hair conditioning, where a positively charged polymer is preferred to effectively treat negatively charged damaged hair. To overcome this limitation, lignin extracted from acacia wood...
Innovative approaches to mitigating microplastic pollution in effluents and soils
Magalhães, Solange; Alves, Luís; Medronho, Bruno; Svanedal, Ida; Norgren, Magnus; Rasteiro, Maria GraçaMicroplastic pollution represents a significant environmental challenge, as microplastics accumulate in effluents and soils, causing serious risks to ecosystems and human health. Efficient removal of these contaminants is essential to mitigate their potential adverse effects. This review summarizes and critically analyses current methods for the removal of microplastics from effluents and soils, focusing on the...
