Strategies to increase prebiotic activity and neurotrophic potential through di...
Silva, Soraia P.; Gonzalez, Abigail; Roupar, Dalila; Salvador, Andreia Filipa Ferreira; Bastos, Rita; Mota, Mariana; Luís, Maria H.; Ferreira, Sónia S.Soluble polysaccharides and oligosaccharides are prebiotic compounds that promote the growth of beneficial gut bacteria and contribute to improved health. Industrial juice production results in juices with moderate amounts of soluble dietary fibre because most polysaccharides that constitute the dietary fibre are retained in the pulp. Incorporation of glucanases and pectinases into the juice production process ...
Modulation of the gut microbiota by tomato flours obtained after conventional a...
Coelho, Marta C.; Costa, Célia; Roupar, Dalila; Silva, Sara; Rodrigues, A. Sebastião; Teixeira, José A.; Pintado, Manuela E.Several studies have supported the positive functional health effects of both prebiotics and probiotics on gut microbiota. Among these, the selective growth of beneficial bacteria due to the use of prebiotics and bioactive compounds as an energy and carbon source is critical to promote the development of healthy microbiota within the human gut. The present work aimed to assess the fermentability of tomato flour...
How prebiotics have been produced from agro-industrial waste: an overview of th...
Gonçalves, Daniela Alexandra; González, Abigail; Roupar, Dalila; Teixeira, J. A.; Nobre, ClarisseBackground The disposal of waste from the food industry represents a major environmental concern. Nonetheless, agro-industrial by-products can be enzymatically converted into low-cost high-value-added products, such as prebiotics, while contributing to a circular economy. As a first approach for health claims validation of these novel products, several gastrointestinal models have been used. Scope and approach ...

Modulation of designed gut bacterial communities by prebiotics and the impact o...
Roupar, Dalila; González, Abigail; Martins, Joana T.; Gonçalves, Daniela Alexandra; Teixeira, J. A.; Botelho, Cláudia M.; Nobre, ClarisseThe impact of prebiotics on human health is associated with their capacity to modulate microbiota, improving beneficial microbiota–host interactions. Herein, the prebiotic potential of microbial-fructo-oligosaccharides (microbial-FOSs) produced by a co-culture of Aspergillus ibericus plus Saccharomyces cerevisiae was evaluated on seven- and nine-strain bacterial consortia (7SC and 9SC, respectively), designed t...
Evaluation of microbial‐fructo‐oligosaccharides metabolism by human gut microbi...
Roupar, Dalila; Coelho, Marta C.; Gonçalves, Daniela A.; Silva, Soraia P.; Coelho, Elisabete; Silva, Sara; Coimbra, Manuel A.; Pintado, ManuelaThe prebiotic potential of fructo‐oligosaccharides (microbial‐FOS) produced by a newly isolated Aspergillus ibericus, and purified by Saccharomyces cerevisiae YIL162 W, was evaluated. Their chemical structure and functionality were compared to a non‐microbial commercial FOS sample. Prebiotics were fermented in vitro by fecal microbiota of five healthy volunteers. Microbial‐FOS significantly stimulated the growt...
OC33 Chromatographic approaches to study pine nut skin: exploitation of its com...
Silva, Soraia P.; Colunga, Alondra; Roupar, Dalila; Salvador, Andreia Filipa Ferreira; Nobre, Clarisse; Reis, S. F.; Freitas, V.; Coimbra, M. A.Pine nut skin (PNS) is an unexploited and uncharacterized by-product recovered during pine nut processing. The exploitation of by-products as sources of valuable compounds agrees with the current demand for the reduction of waste, and a transition to more sustainable production and consumption1. Therefore, PNS characterization and bioactive potentialities were assessed. The utilization of several chromatographi...
Prebiotic potential of fructo-oligosaccharides produced by aspergillus ibericus...
Roupar, Dalila; Gonzalez, Abigail; Martins, Joana T.; Botelho, Cláudia M.; Teixeira, J. A.; Nobre, ClarisseIntroduction The positive effects of prebiotics on human health are associated to their capacity to modulate gut microbiota and consequently, regulate the production of metabolites, such as the short-chain fatty acids (SCFA). Herein, the prebiotic potential of microbial-fructo-oligosaccharides (microbial-FOS) produced by a co-culture of Aspergillus ibericus and Saccharomyces cerevisiae YIL162W [1] was evaluated...

Effect of prebiotic fermentation products from primary human gut microbiota on ...
Parente, Inês; Xavier, Miguel; Roupar, Dalila; Amado, Isabel R.; Berni, Paulo; Botelho, C. M.; Teixeira, J. A.; Pastrana, Lorenzo; Nobre, ClarisseShort chain fatty acids (SCFA) are hypothesised to play a key role in the microbiota-gut-brain crosstalk. However, studies that evaluate the effect of microbiota-targeted interventions, such as prebiotics, probiotics or diet are still sparse, particularly in humans. In this work, the products of fermentation of prebiotic-enriched media by bacteria from primary human faecal samples were tested on differentiated ...
