Fatty acids profile in the honeybee: metabolic pathways, stressor interactions,...
Mutlu, Ceren; Vilas-Boas, MiguelFatty acids play a crucial role in the metabolic activities, health, cognitive development, and behaviors of honeybees. The primary source of fatty acids for honeybees is the pollen consumed, though they can also produce specific fatty acids through de novo synthesis. Among the saturated fatty acids in honeybees, palmitic and stearic acids are the most abundant, while common unsaturated fatty acids include olei...
Bee Pollen as a Dietary Mineral Source: In Vitro Bioaccessibility and Health Ri...
Mutlu, Ceren; Aylanc, Volkan; Vilas-Boas, MiguelPollen, the male gametophyte of flowering plants, is collected by honeybees as a primary source of protein and converted into bee pollen through the enzymatic activity of digestive secretions. The nutrients in bee pollen are available in amounts well beyond those of proteins, comprising macronutrients such as carbohydrates, lipids and dietary fiber, as well as micronutrients such as minerals, vitamins, organic ...
Antimicrobial and wound healing effects associated to cytocompatibility and the...
Machado, Alexandra M.; Marto, Joana; Gonçalves, Lídia Maria; Ribeiro, Helena Margarida; Duarte, Aida; Tomás, Andreia; Falcão, Soraia I.Owing to its applications in both food and pharmaceutical industries honey is regarded as a functional product. This study evaluated 32 Portuguese monofloral honeys and their activity was compared with manuka honey 850 +. The antimicrobial activity was determined against Gram-positive and negative bacteria, and yeast. Antioxidant activity, wound healing ability, and cell viability were studied in the human kera...
Assessing beekeeping potential in a Portuguese area with honey Protected Design...
Silveira, Carlos; Roque, Natália; Fernandez, Paulo; Anjos, O.; Vilas-Boas, MiguelThis study aims to assess the beekeeping potential in a Portuguese area with honey protected designation of origin (PDO) following a multi-criteria decision analysis (MCDA) for supporting beekeepers in the selection of the best locations for apiaries, thus maximizing honey production and reducing the risk of bee colony losses.
Bee Venom-Loaded Niosomes as Innovative Platforms for Cancer Treatment: Develop...
Pinto, Maria Beatriz; Pires, Patrícia C.; Calhelha, Ricardo C.; Silva, Ana Rita; Sousa, Maria João; Vilas-Boas, Miguel; Falcão, Soraia; Veiga, FranciscoDespite past efforts towards therapeutical innovation, cancer remains a highly incident and lethal disease, with current treatments lacking efficiency and leading to severe side effects. Hence, it is imperative to develop new, more efficient, and safer therapies. Bee venom has proven to have multiple and synergistic bioactivities, including antitumor effects. Nevertheless, some toxic effects have been associate...
Using Analytic Hierarchy Process to Assess Beekeeping Suitability in Portuguese...
Roque, Natália; Fernandez, Paulo; Silveira, Carlos; Vilas-Boas, Miguel; Anjos, OféliaSimple Summary Beekeeping is an activity that supports agriculture and wildlife on earth, so it is very important to provide accurate information that is able to help in increasing the profitability of beekeeping and valorize pollination services. In this paper, a new methodology is proposed to assess beekeeping potential using Geographic Information Systems (GIS) and the Analytical Hierarchy Process. The propo...
Evaluating the quality, physicochemical properties, and biological activities o...
Filipe, Márcia Santos; Kowalczyk, Tomasz; Kukula-Koch, Wirginia; Wieczfinska, Joanna; Bangay, Gabrielle; Diaz-Lanza, Ana María; Cardoso, Rossana V.C.Honey, a natural production of honeybees, underscores Turkey’s prominence as one of the world’s largest honey producers. The country’s diverse flora fosters optimal conditions for beekeeping, resulting in the production of exceptional-quality honey. Centauri® Honey is uniquely sourced from remote alpine regions in Turkey, characterized by bees that inhabit isolated caves with access to medicinal endemic flowers...
Structural Characterization of Microcapsules from Common Bee Pollen for the Dev...
Ertosun, Seymanur; Aylanc, Volkan; Peixoto, Andreia F.; Santamaria-Echart, Arantzazu; Russo-Almeida, Paulo; Freire, Cristina; Vilas-Boas, MiguelExine, in the form of a natural microcapsule, refers to the outermost layer of the pollen grains and is composed of a complex mixture of sporopollenin, a highly resistant polymer, which makes it durable and able to withstand harsh conditions. Distinctive features of sporopollenin have attracted interest in the encapsulation of bioactive substances. Herein, we describe the pathway to producing sporopollenin micr...
Melissopallinology characterization of Portuguese honeys with Protected Designa...
Almeida, Paulo Ruddo; Lima, Irailde; Anjos, O.; Paulo, Luísa; Vilas-Boas, MiguelThe European Union created, through Regulations No. 2081/92 and No. 2082/92, Protected Designation of Origin (PDO) as an instrument for valuing agricultural products with distinctive particularities, demanding for this purpose the establishment of requirements set out in a specification book.
Deterpenation of citrus essential oil via extractive distillation using imidazo...
Vilas-Boas, Miguel; Batista, Fábio R.M.; Dias, Rafael M.; Coutinho, João A.P.; Ferreira, Olga; Costa, Mariana C.; Pinho, SimãoThe deterpenation of citrus essential oils (CEO) is crucial in many industries to promote the stability and preserve the organoleptic properties of the final product, improving considerably the oxygenated fraction purity. Methods: Two imidazolium ionic liquids (ILs), [C4mim][OAc] and [C4mim]Cl, were applied as novel separation agents in a deterpenation process constituted by an extractive distillation column an...
