AbstractInternational honey standards are specified in a European Honey Directive and the Codex Alimentarius Standard for Honey, both of which presently under revision. In this article, present knowledge on different quality criteria is reviewed. The standard drafts include methods determination following factors: moisture, ash, acidity, HMF, apparent reducing sugars, sucrose, diastase activity water-insoluble matter. International fructose/glucose content, sucrose content electrical...
Beekeeping with stingless bees (meliponiculture) is practiced in Guatemala, Mexico and Venezuela. In this article we review the medicinal uses of bee honeys these countries. We include from 23 species, their use treatment ocular cataracts pterygium, fatigue, gastritis, ulcers, lung weakness, coughs, wounds bruises; as laxatives fertility enhancers, nutritional value. A proposal on quality standards for honey considered a contribution further regulations.
Stingless bees (Tribe Meliponini) are a diverse group of highly eusocial distributed throughout the tropics and subtropics. Trigona carbonaria honey, from Australia, was characterized by traditional physicochemical parameters (acidity, sugars, diastase, electrical conductivity, hydroxymethylfurfural, invertase, nitrogen, water content) other compositional factors (flavonoids, polyphenols, organic acids, activity), as well total antioxidant capacity radical scavenging activity. For Australian...
The antioxidant effect of several polyphenolic compounds is well known. However, little known about the capacity Venezuelan honey, which has a high content compounds. In this work, genuine honey produced in Mérida, Venezuela was studied using ferrous iron oxidation with xylenol orange method, thiobarbituric acid and determination activity. We found that to decrease significantly concentration lipid hydroperoxides malondialdehyde, during peroxidation process, comparable way other widely...
Honey produced by ten stingless bee species (Melipona crinita, M. eburnea, grandis, illota, Nannotrigona melanocera, Partamona epiphytophila, Ptilotrigona lurida, Scaptotrigona polystica, Scaura latitarsis, and Tetragonisca angustula) from Peru has been characterized according to traditional physicochemical standards (color moisture), biochemical components (flavonoids, polyphenols, nitrites, proteins), bioactive properties (antibacterial activity, antioxidant capacity). Analytical data are...
We aimed to evaluate long-term utilization and results of paediatric radiofrequency catheter ablation (RFCA) in a population-based study.Data from all three centres performing RFCA for the whole population Czech Republic between 1993 2010 were retrospectively reviewed. A total 708 procedures 633 consecutive patients <18 years 716 different substrates tracked, with accessory pathways = 439 (61.3%) atrioventricular nodal reentry tachycardia (AVNRT) 205 (28.6%) being most frequent. Incidence...
Ecuadorian stingless bees (Apidae, Meliponini) have ethnomedicinal interest because their products are used in healing. Diverse remedies consist on pot-honey alone or mixed with infusions. This set of medicinal uses were informed El Oro province by bee keepers –known as meliponicultors− Latin America: bruises, tumors, ocular cataracts, pterygium, inflammation, infections, varicose veins, cleaning blood after childbirth, kidney diseases, tumor, wound healing, and soothing balm before...
Tetragonula carbonaria pot-honeys are highly valued as a food source and for their biological activities in Australia, there is growing interest to know its composition. Phenolic metabolites, which could be related beneficial properties, have not been studied depth yet.Mass spectrometry (MS) coupled liquid chromatography (LC) an advanced technique the study of complex flavonoids present difficult matrices that hampers isolation purification. This allows tentative characterization...
The chemical composition and bioactivity indicators (antioxidant activity, flavonoids, polyphenols) of bee pollen produced by two Meliponini genera (Melipona Scaptotrigona) in Paria Grande, Amazonas state, Venezuela, were compared. Proximal analyses performed triplícate following standard methods. Moisture, ash, crude fat done volumetric methods, proteins the microKjeldahl method (digestion with sulfuric acid catalysts, distillation ammonia steam sodium hydroxide thiosulphate, collection...
The biodiversity of Ecuadorian stingless bees is almost 200 species. Traditional pot-honey harvest in Ecuador mostly done from nests the three genera selected here Geotrigona Moure, 1943, Melipona Illiger, 1806, and Scaptotrigona 1942. 20 samples collected cerumen pots ethnic honeys "abeja de tierra", "bermejo", "cushillomishki" were analyzed for qualitative quantitative targeted 1H-NMR honey profiling, Honey Authenticity Test by Interphase Emulsion (HATIE). Extensive data organic compounds...
SUMMARYTwenty-seven stingless bee honeys from the west and south of Venezuela were examined for diastase (α ß-amylase) invertase (α-glucosidase) activity Diastase (g starch hydrolysed/100 g honey/h) was very low in Meliponini Scaptotrigona spp. (2.6–3.5 number), much higher other Trigonini (6.6–35.6). Invertase (μmoles p-nitrophenyl glucopyranoside/kg honey/min) varied 9.6 to 169.1 15.9 214.3 honey, not statistically different both groups. The correlation between low, but enzymes produced a...
