Effect of Xylo-oligosaccharides and cello-oligosaccharides obtained from Agro-i...
Silva, Marcos Fellipe da; Batista, José Josenildo; Colunga, Alondra; Pereira, Catarina Rodrigues; Teixeira, J. A.; Nobre, Clarisse; Goldbeck, RosanaAgro-industrial residues, traditionally considered low-value by-products, have shown great potential to produce prebiotic oligosaccharides, such as xylo-oligosaccharides (XOS) and cello-oligosaccharides (COS). This study investigated the effects of XOS and COS, derived from sugarcane bagasse (SB) and corn husks (CH) by enzymatic hydrolysis, on the modulation of human intestinal microbiota in vitro. Cellulose an...
Process intensification: enhancing mass transfer in a gasliquid-solid system op...
Almeida, F.; Teixeira, J. A.; Rocha, F.; Ferreira, A.Process intensification (PI) demands reactor concepts that deliver high mass-transfer rates, controlled hydrodynamics and low energy consumption under continuous operation, challenges that are especially acute for three-phase (gasliquidsolid) systems due to fouling, solids accumulation and poor gasliquid mass transfer in conventional devices. In this research paper, the first continuous co-current study of an o...
Physalia physalis-a source of bioactive collagen for the cosmetic industry
Fernandes, Raquel; Oliveira, Cristiana; Sousa, Diana F.; Costa-Barbosa, Augusto; Sampaio, Paula; Reis, Luis; Fidalgo, Javier; Barros, Ana N.Collagen, the most abundant structural protein in animals, is fundamental for tissue integrity and regeneration. Conventional mammalian sources face limitations related to sustainability, safety, and ethical concerns, underscoring the need for alternative biomaterials. Marine organisms, particularly jellyfish, offer a promising eco-friendly collagen source. In this study, collagen and collagen-derived peptides ...
Enhancing coconut-based beverages with symbiotic microcapsules: evaluation of p...
Araújo, Alessandra Silva; Cavalcanti, Isabella Macário Ferro; Campos, Luís André de Almeida; Souza, Felipe Ravelly Alves deThis study highlights the effectiveness of ionic gelation combined with vibratory extrusion and chitosan hydrochloride coating as a robust strategy for the microencapsulation of Lacticaseibacillus rhamnosus GG intended for application in complex food matrices. The developed symbiotic microcapsules demonstrated desirable morphological and structural characteristics and provided significant protection to the enca...
Impact of previous exposure to fraud on Portuguese consumer perceptions and att...
Sousa, Isabel; Costa, Maria João; Moura, Ana Pinto de; Teixeira, J. A.; Cunha, Luís MiguelConcerns over food fraud continued to plague the food supply chain. Within the various definitions of food fraud, in the scope of Regulation (EU) 2019/1715, food fraud is referred to as a non-compliance concerning any suspected intentional action by businesses or individuals, to deceive purchasers and gain undue advantage therefrom, in violation of the rules referred to in Article 1(2) of Regulation (EU) 2017/6...
Tailoring seaweed proteins: impact of extraction techniques on functional prope...
Nunes, Rafaela Augusta Freitas; Rodrigues, Rui Miguel Martins; Moreira, Catarina; Teixeira, J. A.; Rocha, Cristina M.R.The increasing demand for food proteins caused by the exponential increase in world population has led to a deep search for novel protein sources. Seaweed emerges as a promising biomass with interesting nutritional composition and environmental performance. In this work, proteins were extracted from red seaweed Porphyra dioica using a sequential extraction methodology (H2O/NaOH). Then, extracts were purified us...
Bioenergy potential of crop residues in the Kurdistan Region of Iraq (KRI)
Agha, Balen; Pereira, M. A.; Teixeira, J. A.; Pochwatka, Patrycja; Dach, Jacek; Ferreira, PaulaProducing bioenergy from agricultural waste offers a promising solution to meet rising energy demand, in particular in developing countries still facing significant energy shortages. This study proposes an indirect estimation method to estimate the bioenergy potential from crop residues, focusing on key crops widely cultivated across the four provinces (Erbil, Sulaimaniyah, Duhok, and Halabja) of the Kurdistan ...
Germinated quinoa (Chenopodium quinoa Willd): effects on mineral composition, a...
García-Torres, Silvia Melissa; Teixeira, J. A.; René Encina-Zelada, Christian; Silva, Cristina L. M.; Gomes, Ana Maria[Excerpt] Introduction Transforming food systems is crucial for enhancing nutrition, food security, and sustainability. Eco-friendly processing techniques, such as grain germination, can improve the nutrition al and functional properties of Andean grains.[...]
Assessing process variable effects on laccase-mediated treatment for enhanced s...
Michelin, Michele; Gomes, Daniel Gonçalves; Freitas, Emanuelle N.; Alnoch, Robson C.; Salgado, José Carlos S.; Coelho, Eduardo João LouroLignocellulosic materials (LCM) have gained popularity as a substitute for petroleum, enabling the production of biofuels and various compounds. Eucalyptus bark residue (EBR), generated by pulp and paper mills, is a prime illustration of such materials. The conversion of holocellulose in these materials typically involves the application of enzymes. Nevertheless, these materials may still contain lignin, widely...
Bioactive potential of a grape stem blend: a sustainable approach to skin regen...
Serra, Mónica; Botelho, C. M.; Sousa, Diana F.; Almeida, Hugo; Casas, Ana; Teixeira, J. A.; Barros, Ana NovoThe European wine industry is embracing sustainability through circular economy principles, particularly by valorizing by-products, such as grape stems. Grape stems are rich in phenolic compounds with recognized health benefits. This study investigates the bioactive potential of molecules extracted from a blend of grape stems (GS blend extract). The GS blend extract was chemically characterized in terms of tota...
