Use of Black Pepper Essential Oil to Produce a Healthier Chicken Pâté
Rodrigues, Sandra; Leite, Ana; Vasconcelos, Lia; Pereira, Etelvina; Seixas, Natália L.; Estevinho, Letícia M.; Teixeira, AlfredoThis study aims to explore the effect of using black pepper essential oil (BPEO) to produce a healthier chicken pâté. Four different formulations were produced: a control formulation without back pepper and three with increasing BPEO contents. To test the effect of using BPEO, physiochemical analyses were performed at two different moments, 8 and 21 days after production. Microbiological analyses were performed...
The Effect of Incorporating Fermented Elderberries (Sambucus nigra) into Bread:...
Seixas, Natália L.; Paula, Vanessa B.; Dias, Teresa; Dias, Luís G.; Estevinho, Letícia M.Elderberries, known for their antioxidant, anti-inflammatory, and antiviral properties, have traditionally been used to prevent and treat infections and boost the immune system. By increasing the quantity and quality of certain compounds, fermentation can potentially make them more effective as food additives. The aim of this study was to evaluate the effect of incorporating fermented elderberries on the bioact...

Boutoub, Oumaima; El-Guendouz, Soukaina; Matos, Isabel; El Ghadraoui, Lahsen; Costa, Maria Clara; Carlier, Jorge; Faleiro, Maria LeonorAlthough the plants of the genus Euphorbia are largely exploited by therapists in Morocco, the composition and antibacterial activities of propolis from these plants are still unknown. To address this gap, this study aimed to characterize the pollen type, the volatile compounds, and the phenolic and mineral profiles of three Euphorbia propolis samples collected in Morocco and evaluate their antimicrobial activi...

Volatile characterization of honey with dominance of Bupleurum spinosum pollen
Elamine, Youssef; Machado, Alexandra M.; Estevinho, Letícia M.; Lyoussi, Badiâa; Figueiredo, Ana Cristina; Miguel, MariaMoroccan honey with Bupleurum spinosum (Apiaceae/Umbelliferae) as the main pollen source is locally known as Zantaz honey. In the present work, the volatiles from 18 honeys of this type, were isolated by hydrodistillation and analysed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS), for volatiles quantification and identification. The percentage composition of the volatiles and polle...
Quality of bee pollen submitted to drying, pasteurization, and high-pressure pr...
Anjos, O.; Seixas, Natália; Antunes, Carlos Alberto Lopes; Campos, Maria da Graça; Paula, Vanessa Branco; Estevinho, Letícia M.Bee Pollen is a valuable and useful natural food product that can be used for different purposes, among which medical ones. This matrix is deemed a superfood because of its chemical composition, which is rich in nutrients and possesses significant bioactivities, including antioxidant and microbiological properties. Nevertheless, the storage conditions and processing methods must be optimized to maintain their p...

Paula, Vanessa Branco; Pedro, Soraia; Campos, Maria da Graça; Delgado, Teresa; Estevinho, Letícia M.; Anjos, O.Some diseases still need better therapeutic approaches, including the prevention of development. Natural resources are investigated with this purpose; among them, we decided to use an invasive plant as a main strategy. This will help in two ways: screening new compounds in flowers prevents the plant from causing widespread damage by controlling the dissemination and also obtains crude material for further appli...

Comparative study of the antioxidant and enzyme inhibitory activities of two ty...
Boutoub, Oumaima; EL-GUENDOUZ, Soukaina; Manhita, Ana; Dias, Cristina Barrocas; Estevinho, Letícia M.; Paula, Vanessa B.; Carlier, JorgeHoney is a natural food product very famous for its health benefits for being an important source of antioxidant and phenolic compounds. <i>Euphorbia</i> honeys obtained from different regions of Morocco were evaluated for their ability to inhibit acetylcholinesterase, lipoxygenase, tyrosinase and xanthine oxidase activities. Their antioxidant properties were evaluated using the: 2,2-diphenyl-1-picrylhydrazyl (...
