Response surface methodology and artificial neural network modeling as predicti...
Silva, Ana Rita; Ayuso, Manuel; Oludemi, Taofiq; Gonçalves, Alexandre; Melgar Castañeda, Bruno; Barros, LillianThis study optimized the extraction of three major phenolic compounds (oleuropein, tyrosol, and verbascoside) from olive pomace using microwave- and ultrasonic-assisted methods. Screening factorial design (SFD) and central composite design (CCD) were employed, and response surface methodology (RSM) and artificial neural networks (ANN) were used for data modeling. The microwave-assisted method in the SFD yielded...
Exploring the potential of Hermetia illucens larvae extracts: A promising appro...
Filipe, Márcia Santos; Cardoso, Rossana V.C.; Ayuso, Manuel; Murta, Daniel; Díaz-Lanza, Ana M.; Rosado, Catarina; Pires, Tânia C.S.P.Globally, the yearly disposal of 1.3 billion tonnes of food raises environmental and public health concerns. Black soldier fly (BSF) larvae present a sustainable solution, converting organic waste into nutrient-rich biomass. The extracted oil from BSF larvae, rich in fatty acids (FA), offers an eco-friendly alternative for the cosmetic industry. In this study, larvae sourced from a Portuguese company were fed o...
Unveiling the metabolites underlying the skin anti-ageing properties of Cytinus...
Silva, Ana Rita; Ayuso, Manuel; García, Pablo A.; Barros, Lillian; Edrada-Ebel, RuAngelieThe genus Cytinus, recognised as one of the most enigmatic in the plant kingdom, has garnered attention for its bioactive potential, particularly its skin anti-ageing properties. Despite this recognition, much remains to be accomplished regarding deciphering and isolating its most active compounds. Hypothesis: This study aimed to identify the compounds responsible for C. hypocistis skin anti-ageing potential. M...
Non-alkaloid nitrogen containing compounds
Pereira, Eliana; Fernandes, Filipa Alexandra; Mandim, Filipa; Ayuso, Manuel; Ferreira, Isabel C.F.R.; Caleja, Cristina; Barros, LillianPlants have been the target of a growing interest by the scientific community in chemical and nutritional characterization studies, due to the presence of bioactive compounds and their potential industrial use, namely in food and pharmaceutical sectors. Different secondary metabolites found in plants ensure their survival and reproduction. Non-alkaloids compounds are an important group of secondary metabolites ...
Fig “Ficus carica L.” and its by-products: A decade evidence of their health-pr...
Ayuso, Manuel; Carpena Rodríguez, María; Taofiq, Oludemi; Albuquerque, Tânia Gonçalves; Simal-Gandara, Jesus; Oliveira, Beatriz; Prieto Lage, Miguel A.The food industry constantly searches for natural derived bioactive molecules with preventive and therapeutic effects using innovative and sustainable strategies. Fig production and processing generate a considerable amount of by-products (leaves, pulp, peels, seeds, and latex) with limited commercial exploitation and negative impact on the environment. These by-products are important sources of high value-adde...
Bread freezing as a new alternative to consumption
Pascoalino, Liege; Ayuso, Manuel; Pereira, Eliana; Ferreira, Elisabete; Ferreira, Isabel C.F.R.; Barros, LillianThe growing consumer interest in health and food safety, as well as the increased consumption of fresh food, make frozen bread an increasingly popular alternative. This type of bread has several advantages, such as, large-scale manufacturing, economize manpower and equipment, and lowering production costs. Furthermore, one of the ways to extend shelf-life of ready-to-eat bread is to use deep freezing systems [1...
Evaluation of parasite and host phenolic composition and bioactivities − The pr...
Silva, Ana Rita; Ayuso, Manuel; Pereira, Carla; Dias, Maria Inês; Kostić, Marina; Calhelha, Ricardo C.; Soković, Marina; García, Pablo A.Cytinus hypocistis (L.) L. is a comestible holoparasite with great potential for cosmeceutical application. Although its high tannin content has been associated with its bioactive and inhibitory enzyme properties, this is the first report establishing a relationship between parasite and host (Halimium lasianthum (Lam.) Greuter) phenolic profile and bioactive properties. Thus, five extracts (aerial and root extr...
Exploring the bioactive potential of Artemisia annua L. hydroethanolic extracts...
Calhelha, Ricardo C.; Alves, Maria José; Barros, Lillian; Pinho, Simão; Ayuso, ManuelArtemisia annua L. is known for producing artemisinin, a sesquiterpene lactone compound, which is applied to treat of malaria [1]. Its pharmacodynamic and pharmacokinetic characteristics, as well as its strong capacity for Plasmodium elimination, have raised many expectations for this new class of antimalarial drugs [2]. However, this plant has been also used in traditional Chinese medicine to treat of various ...
Metabolomic approach to assess the effect of the foraging year on the anti-elas...
Silva, Ana Rita; Ayuso, Manuel; García, Pablo A.; Barros, Lillian; Edrada-Ebel, RuAngelieCytinus hypocistis (L.) L. is a wild edible parasitic plant on numerous members of the Cistaceae family. Although its bioactive properties were potentially attributed to its hydrolysable tannin content, its chemical composition is largely unknown, and the bioactive substances have not yet been identified [1,2]. Thus, this work aimed to investigate its potential to inhibit human elastase, an important anti-agein...
Unsupervised exploratory analyses as a raw material selection tool to develop i...
Ayuso, Manuel; Aguiló-Aguayo, Ingrid; Barros, LillianThe LOCALNUTLEG project aims to valorise local Mediterranean nuts and legumes by developing innovative plant-based food products. Thus, one of its priorities is to obtain a catalogue with the complete nutritional and biochemical characterisation of the chosen raw materials, which will facilitate a better selection. In this sense, the work presented at this congress aimed to determine the nutritional characteris...
