Comparative analysis of bee pollen quality following different storage techniques
Anjos, O.; Seixas, Natália; Antunes, Carlos; Campos, Maria da Graça; Paula, Vanessa; Estevinho, Leticia M.Bee pollen is aknowledged as a versatile natural food valued for its nutritional and medicinal benefits, attributed to its rich chemical composition boasting notable bioactivities like antioxidant and antimicrobial.
Exploring the therapeutic potential of cannabinoids in cancer by modulating sig...
Faiz, Manal Bint; Naeem, Faiza; Irfan, Muhammad; Aslam, Muhammad Adeel; Estevinho, Leticia M.; Ateşşahin, Dilek Arslan; Alshahrani, Asma M.For centuries, cannabinoids have been utilized for their medicinal properties, particularly in Asian and South-Asian countries. Cannabis plants, known for their psychoactive and non-psychoactive potential, were historically used for spiritual and remedial healing. However, as cannabis became predominantly a recreational drug, it faced prohibition. Recently, the therapeutic potential of cannabinoids has sparked ...
Revolutionizing fruit juice: exploring encapsulation techniques for bioactive c...
Gómez-Gaete, Carolina; Avendaño-Godoy, Javier; Escobar-Avello, Danilo; Campos-Requena, Víctor H.; Rogel-Castillo, Cristian; Estevinho, Leticia M.Bioactive compounds in food and beverages, including fruit juices, are susceptible to degradation or oxidation during processing and storage. This vulnerability can lead to a reduction in nutritional value and overall quality of the products. The objective of this research is to explore the potential of encapsulation techniques in preserving and enhancing the nutritional value of fruit juices. The encapsulation...
Volatile characterization of honey with dominance of Bupleurum spinosum pollen
Elamine, Youssef; Machado, Alexandra M.; Estevinho, Leticia M.; Lyoussi, Badiâa; Figueiredo, Ana Cristina; Miguel, Maria GraçaMoroccan 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...
Microbiological and Physicochemical Evaluation of Hydroxypropyl Methylcellulose...
Paula, Vanessa B.; Dias, L.G.; Estevinho, Leticia M.Dairy products are highly susceptible to contamination from microorganisms. This study aimed to evaluate the efficacy of hydroxypropyl methylcellulose (HPMC) and propolis film as protective coatings for cheese. For this, microbiological analyses were carried out over the cheese' ripening period, focusing on total mesophilic bacteria, yeasts and moulds, lactic acid bacteria, total coliforms, Escherichia coli, an...
Phenolic Class Analysis in Honey: Comparison of Classical and Single UV Spectru...
Paula, Vanessa B.; Sousa-Dias, Miguel L.; Seixas, Natália da Assunção Lisboa; Combarros-Fuertes, Patricia; Estevinho, Leticia M.; Dias, L.G.The analytical results from a study of 16 honey samples (extra white to dark honey color range) of phenolic compounds obtained using the single UV spectrum methodology and classical spectrophotometric methods (Folin–Ciocalteu and AlCl3 methods) are presented. The first method quantified all classes of phenolic compounds in honey’s SPE-C18 extract: the total hydroxybenzoic acid content (concentrations between 0....
The High Pressure Preservation of Honey: A Comparative Study on Quality Changes...
Scepankova, Hana; Majtan, Juraj; Estevinho, Leticia M.; Saraiva, Jorge A.In commercially available honey, the application of a heat treatment to prevent spoilage can potentially compromise its beneficial properties and quality, and these effects worsen with extended storage. The high-pressure processing (HPP) of honey is being explored, but its long-term impact on honey quality has not been characterised yet. This study evaluated the effects of HPP and thermal processing on the micr...
Chemical Characterization and Biological Properties Assessment of Euphorbia res...
Boutoub, Oumaima; El-Guendouz, Soukaïna; Matos, Isabel; El Ghadraoui, Lahsen; Costa, Maria Clara; Carlier, Jorge D.; 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...
Plant-Based Beverages: Consumption Habits, Perception and Knowledge on a Sample...
Anjos, Ofélia; Pires, Patrícia C.; Gonçalves, Joana D.; Estevinho, Leticia M.; Mendonça, António G.; Guiné, Raquel P.F.Plant-based beverages (PBB) consumption has increased significantly worldwide due to an interest in vegetarian/vegan diets, taste preferences, health and ethical and environmental issues. Therefore, this study intends to investigate consumption habits, consumer preferences and consumers’ level of knowledge about PBB. In this study, a voluntary, anonymous questionnaire survey was applied to a sample of participa...
Biological activities of endophytic fungi isolated from Annona muricata Linnaeu...
Silva, I.M.M.; Silva, Reanne M.M.; Paula, Vanessa B.; Estevinho, Leticia M.This systematic review integrates the data available in the literature regarding the biological activities of the extracts of endophytic fungi isolated from Annona muricata and their secondary metabolites. The search was performed using four electronic databases, and studies’ quality was evaluated using an adapted assessment tool. The initial database search yielded 436 results; ten studies were selected for in...
