Exploring geographical influences on physicochemical characteristics of honey: ...
Soares, Sónia; Magalhães, Leandro; Moreira, Manuela M.; Rede, Diana; Fernandes, Virgínia Cruz; Viegas, Olga; Pinto, Edgar; Almeida, AgostinhoIn recent years, there has been a substantial increase in the global consumption of honey, driven by the high demand for natural products that offer health benefits. Consequently, consumers show a preference for honey, recognised for its superior quality, namely honey with a Protected Designation of Origin (PDO) or honey produced in protected areas, as it is associated with superior attributes and characteristi...
Unveiling the geographical influence on honey's physicochemical profile: a case...
Soares, Sónia; Magalhães, Leandro; Moreira, Manuela M.; Rede, Diana; Fernandes, Virgínia Cruz; Viegas, Olga; Pinto, Edgar; Almeida, AgostinhoIn recent years, global honey consumption has significantly increased due to the rising demand for natural products with health benefits. Consumers are particularly drawn to honey recognized for its superior quality, such as Protected Designation of Origin (PDO) honey or honey produced in protected areas, which is associated with distinctive characteristics. Portugal stands among the top producers of PDO honey,...
Honey from natural park of Montesinho: insights from DNA extraction methodology...
Soares, Sónia; Magalhães, Leandro; Barbosa, Rui; Delerue-Matos, CristinaHoney is a sweet natural substance produced by bees from the nectar of plants and/or secretions of living parts of plants. It consists essentially of simple sugars (68%) and water (18%) and smaller quantities of other components such as vitamins, minerals, proteins, organic acids, phenolic compounds, among others. Those are highly dependent of the botanical species visited by bees, conferring to each honey diff...
Honey as an Adjuvant in the Treatment of COVID-19 Infection: A Review
Soares, Sónia; Bornet, Mélina; Grosso, Clara; Ramalhosa, Maria João; Gouvinhas, Irene; Garcia, Juliana; Rodrigues, Francisca; Delerue-Matos, CristinaSince ancestor times, honey has been used to promote human health due to its medicinal, and nutritious properties, mainly due to bioactive compounds present, such as phenolic compounds. The emergence of COVID-19, caused by the SARS-CoV-2 virus, led to the pursuit of solutions for the treatment of symptoms and/or disease. Honey has proven to be effective against viral infections, principally due to its potential...
A Política nacional de educação especial para a inclusão escolar em Angola: per...
Sanches, Isabel Rodrigues; Soares, SóniaA necessidade de garantir um ensino de qualidade e acessível a todos os alunos levou a que os Estados procurassem criar políticas direcionadas ao ensino inclusivo, mediante ratificação de convenções internacionais ou aprovação de legislação oficial a nível do ordenamento jurídico interno. A exequibilidade dessas políticas nem sempre se afigura fácil, defrontando-se os sujeitos na sua implementação com vários ob...
Towards honey authentication: Differentiation of Apis mellifera subspecies in E...
Soares, Sónia; Grazina, Liliana; Mafra, Isabel; Costa, Joana; Pinto, M. Alice; Oliveira, Beatriz; Amaral, Joana S.Honey is the natural sweet substance produced by Apis mellifera honeybees in Europe. Depending on the country/region, the A. mellifera subspecies native to Europe belong to three different lineages: A (A. m. iberiensis), M (A. m. iberiensis and A. m. mellifera) and C (A. m. ligustica and A. m. carnica). In this work, two DNAbased approaches were developed with the aim of entomological authentication of European...
Chemical characterization and bioactive properties of a coffee-like beverage pr...
Pinto, Diana; Diaz Franco, Santiago; Silva, Ana Margarida; Cupara, Snezana; Koskovac, Marijana; Kojicic, Ksenija; Soares, Sónia; Rodrigues, FranciscaIn the present study, a coffee-like beverage was prepared from Quercus cerris seeds. Seeds presented 60.4% carbohydrates (of which 26.9% is fiber), 6.3% proteins and 4.0% fat. In the coffee-like beverage, the TPC and TFC were 2070.2 mg GAE per L and 285.3 mg CEQ per L, respectively. The IC50 values determined using FRAP and DPPH assays were, respectively, 203.1 mg L-1 and 271.6 mg L-1. Concerning the reactive s...
Novel diagnostic tools for Asian (Apis cerana) and European (Apis mellifera) ho...
Soares, Sónia; Grazina, Liliana; Mafra, Isabel; Costa, Joana; Pinto, M. Alice; Duc, Hanh Pham; Oliveira, Beatriz; Amaral, Joana S.Honey can be produced by different species of honeybees, with two being of economic importance due to their use in apiculture, namely Apis mellifera (known as European honeybee) and Apis cerana (known as Asian honeybee). Due to the decline of the wild populations of the Asian honeybee, this honey generally attains much higher market value, being prone to adulteration. This work aims at proposing new tools, base...
Botanical authentication of lavender (Lavandula spp.) honey by a novel DNA-barc...
Soares, Sónia; Grazina, Liliana; Costa, Joana; Amaral, Joana S.; Oliveira, Beatriz; Mafra, IsabelMonofloral honeys (such as, lavender honey) are highly appreciated by the consumers due to their flavour, taste and properties. However, since they are considered prime products, they are often targets of adulteration. This work exploits DNA barcoding combined with high resolution melting (HRM) analysis to establish the botanical origin of honey, using lavender honey as a case study. The plastidial matK gene wa...
Entomological authentication of honey based on DNA markers: differentiation of ...
Amaral, Joana S.; Soares, Sónia; Grazina, Liliana; Mafra, Isabel; Costa, Joana; Pinto, M. Alice; Duc, Hanh Pham; Oliveira, BeatrizAccording to the European Union legislation, honey is the natural sweet substance produced by Apis mellifera, also known as European honeybee. However, in other regions of the world, honey is traditionally obtained from other bee species. Among those, A. cerana (also known as Asian honeybee) is also of economic importance since it is used in apiculture. Due to the decline of the wild populations of the A. ceran...
