In the present study, the physicochemical properties and antioxidant activities of different Iranian honey samples are investigated using various multivariate techniques in order to develop a quality control model. Forty-eight Iranian honey samples were tested for 15 physicochemical and antioxidant parameters. The parameters for which the samples were tested included color intensity, moisture, ...

one of the superficial problems of public health is mycotic inflection that its incidence is not correctly known. the most important disease of them is dermatophytosis that comes through by dermatophytes as the major group of keratinophilic fungi. honey is bee product that has been used as a medicine since ancient times in many cultures, and is still used in folk medicine. this study was design...

This study was part of a large-scale monitoring project to assess the possible effects of Elado® (10 g clothianidin & 2 g β-cyfluthrin/kg seed)-dressed oilseed rape seeds on different pollinators in Northern Germany. Firstly, residues of clothianidin and its active metabolites thiazolylnitroguanidine and thiazolylmethylurea were measured in nectar and pollen from Elado®-dressed (test site, T) a...

the aim of the study was the analysis of lithuanian honeys for the presence of the spores of clostridium botulinum. the analyses were performed on multifloral, honeydew, nectar-honeydew, rape, buckwheat, heather and linden honey bought in direct sale. prior to culture on solid media the samples were prepared by supernatant filtration method and cultured in parallel in cooked meat medium (cmm) a...

Background & Aims of the Study : Consumption of honey has remarkably increased in the last years all over the world. Factors such as plant species, environmental, processing, and storing condition are affecting honey quality. The purpose of this study was to evaluation of Hygienic quality of honey samples produced from Qazvin province. Materials and Methods: 34 fresh honey Samples were obta...

Manuka honey, obtained from Leptospermum scoparium flowers in New Zealand, has strong antibacterial properties. In this study, plausible authentication of the manuka honey was inspected by measuring leptosperin, methyl syringate 4-O-β-D-gentiobiose, along with methyl syringate. Despite a gradual decrease in methyl syringate content over 30 days at 50 °C, even at moderate 37 °C, leptosperin rema...

Physicochemical analyses were carried out to evaluate 27 samples of honeys from three species of the Brazilian genus Melipona (M. capixaba, M. rufiventris and M. mondury) from Espírito Santo and Minas Gerais States. The parameters water activity (Aw), percentage of soluble solids (Brix %), pH, acidity (meq/Kg) and moisture (%) were evaluated. The honey characteristics obtained from these sample...

Mass fraction of ash is a quality criterion for determining the botanical origin of honey. At present, this parameter is generally being replaced by the measurement of electrical conductivity (k). The value k depends on the ash and acid content of honey; the higher their content, the higher the resulting conductivity. A linear regression model for the relationship between ash and electrical con...

An analytical method was developed to determine pesticides of various chemical classes in soil, juice and honey using analyte protectants to counteract the enhancement of the chromatographic response produced by the presence of matrix components (matrix effect). This effect was more pronounced for soil and honey samples than for juice samples; regarding the pesticide chemical class, organochlor...

An analytical method for the simultaneous determination of residues of eight neonicotinoid insecticides and two metabolites in honey using LC-MS/MS was developed and validated. Two approaches of sample preparation were investigated, with the final method involving acetonitrile extraction and subsequent cleanup by dispersive solid-phase extraction (QuEChERS type). Validation was based on quintup...
