| Abstract Honey, produced by honeybees from nectar in flowers and plants, is an aqueous supersaturated sugar solution, mainly composed of fructose and glucose. The quality and biochemical properties of honey are related to honey maturity, production methods, processing and storage conditions, climatic conditions as well as the nectar source of the honey. In this study, 35 honey samples of different sizes and packaging all of which were sold in Istanbul were examined in terms of some physicochemical and microbiological properties. All samples were floral liquid honey. The physicochemical characterizations were as follows: average moisture (16.31±1.40%), ash (0.30±0.29%), hydroxymethylfurfural (HMF) (8.09±7.63 mg/kg), pH (4.32±0.34), acidity (30±9 meq/kg). In... |

| PHENOLIC ACIDS, FLAVONOIDS AND ANTIOXIDANT ACTIVITY IN HONEY OF Melipona fasciculata, M. flavolineata (Apidae, Meliponini) AND Apis mellifera (Apidae, Apini) FROM THE AMAZON. Honey produced by three stingless bee species (Melipona flavolineata, M. fasciculata and Apis mellifera) from different regions of the Amazon was analyzed by separating phenolic acids and flavonoids using the HPLC technique. Data were subjected to multivariate statistical analysis (PCA, HCA and DA). Results showed the three species of honey samples could be distinguished by phenolic composition. Antioxidant activity of the honeys was determined by studying the capacity of inhibiting radicals using DPPH assay. Honeys with higher phenolic compound contents had greater antioxidant... |

| An electronic tongue system was developed based on 20 all-solid-state potentiometric sensors and chemometric data processing, with polymeric membranes applied on solid conducting silver-epoxy supports and a Ag=AgCl reference electrode. The sensor array was applied to 52 commercial honey samples obtained randomly from different regions of Portugal. These samples were analysed independently for their pollen profiles by biological techniques and the data collected with the tongue were evaluated for discrimination of the samples with multivariate statistical methods (principal component analysis and linear discriminant analysis), to investigate whether the device may provide an analytical alternative for classification of honey samples with respect to pollen... |

| The study researched the costs and returns on typical small beekeeping farms from five districts in Serbia. On the basis of the field research, data on the number of beehives, type of product, volume of production per beehive and values per measurement unit were collected. In order to demonstrate the competitiveness of various agricultural products, analysis of the available data was performed using analytical calculations. According to the analysis, the labour costs comprise about 49.65%to 64.15%of the variable costs on beekeeping farms in the Raška and Šumadija districts, respectively. Production is most economical on the bee farm in the district of Srem, where every dinar spent in production creates a value of 2.22 dinars, while the farm from the... |

| An experiment was conducted to evaluate the potential of honey, propolis, and bee pollen for the reversal of lipid peroxidation induced by tebuconazole (TEB) in South American catfish (Rhamdia quelen), in which the concentration of thiobarbituric acid reactive substances (TBARS), the activity of the antioxidant enzyme glutathione-S-transferase (GST) and the concentrations of non-enzymatic antioxidants, reduced glutathione (GSH), ascorbic acid, and non-protein thiols were assessed. Honey (0.125 g L-1) and bee pollen (0.05 g L-1) added to the water reverse the production of TBARS induced by TEB, while propolis demonstrated a pro-oxidant effect, inducing an increase in TBARS production. The data presented herein suggest that the addition of water to honey and... |

| The antioxidant activity of Portuguese honeys was evaluated considering the different contribution of entire samples and phenolic extracts. Several chemical and biochemical assays were used to screen the antioxidant properties of entire honeys with different colour intensity and phenolic extracts: reducing power, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging capacity, and inhibition of lipid peroxidation using the b-carotene linoleate model system and the thiobarbituric acid reactive substances (TBARS) assay. The amounts of phenols, flavonoids, ascorbic acid, b-carotene, lycopene and sugars present in the samples were also determined. The highest antioxidant contents and the lowest EC50 values for antioxidant activity were obtained in the dark... |

| Resumo: O mel brasileiro é produzido principalmente por abelhas africanizadas a partir do néctar ou da secreção das plantas e, devido às suas características genéticas dessas espécies de abelhas, dispensa o uso de antibióticos e pesticidas, como acaricidas e fungicidas. A composição das amostras de méis está intimamente relacionada com o tipo de florada utilizada por estas abelhas para a elaboração do produto final. Um dos componentes de grande importância são os minerais presentes no mel que representam de 0,02% a 1%. Dentre estes minerais observamos os chamados metais pesados, que podem indicar tanto a origem geográfica do mel quanto o nível de poluição ambiental por estes metais. Logo, faz-se necessário a pesquisa da presença ou não de metais pesados... |

| Além da abelhas Africanizadas (Apis mellifera L.), as abelhas indígenas sem ferrão ou meliponíneos (Meliponinae) são potenciais produtoras de mel. Esse produto apresenta carcterísticas distintas do mel produzido pelas abelhas do gênero Apis, sendo muito apreciado pelos consumidores. Entretanto, são escassos os dados científicos a respeito da composição desse mel na literatura nacional e internacional. A proposta deste trabalho é avaliar as características físico-químicas do mel produzido por meliponíneos. As análises físico-químico foram realizadas de acordo com as técnicas descritas pela AOAC (Association of Official Analytical Chemists), e pela European Honey Comission, conforme recomendado pela CAC (Codex Alimentarius Comission). Os resultados obtidos... |

| Honey has always been regarded as a food which is advantageous for one’s health and as a product which has healing qualities. For this reason, is necessary to protect consumers from the fraudulent mislabeling of inferior honeys. The purpose of this study was to investigate some properties of artisanal honey samples (n = 45) collected from the Northwest of Portugal by using different honey analysis tests such as moisture, ash, pH, free acidity, electrical conductivity, hydroxymethylfurfural (HMF), apparent sucrose, reducing sugars and diastase activity. 77.8% of the total exceeded the quality parameters and should be labeled as ‘‘virgin” (humidity 618% and HMF 6 25 mg/kg). The present study found a linear correlation (y = 0.551x 0.089; R = 0.995) between... |
