Based on qualitative and quantitative melissopalynological analyses, 19 Chinese honeys were classified by botanical origin to determine their floral sources. The honey samples were collected during 2010-2011 from the central region of Shanxi Province, North China. A diverse spectrum of 61 pollen types from 37 families was identified. Fourteen samples were classified as unifloral, whereas the re...

With the current upward trend in nutritional and health awareness, the consumers demands for high quality probiotic product with acceptable sensory characteristics. The main purpose of this research was to observe the influence of different levels of honey (5%, 10% and 15% and 20%) to yoghurt and its effect on viability of microbial flora of yoghurt, chemical and sensory characteristics. Honey ...

Pyrrolizidine alkaloids (PAs) in honey can be a potential human health risk. So far, it has remained unclear whether PAs in honey originate from pollen or floral nectar. We obtained honey, nectar, and plant pollen from two observation sites where Echium vulgare L. was naturally abundant. The PA concentration of honey was determined by targeted analysis using a high pressure liquid chromatograph...

A total of 3917 honey samples and 119 'bee pollen' samples (pollen collected by honeybees) were analysed for pyrrolizidine alkaloids (PAs). Some 0.05 M sulphuric acid was used for extraction followed by a clean-up step by means of solid-phase extraction. Separation and detection was achieved by target analysis using an LC-MS/MS system. PAs were found in 66% of the raw honeys (bulk honey not yet...

honey is the oldest natural food produced by honeybee and comprises wide variety of valuable ingredients including carbohydrate, proteins, minerals, vitamins, organic acids, polyphenols and flavonoids that contribute to well-known therapeutic properties. this review provide available scientific information on different ways of honey adulteration and chemical contamination with the certain focus...

BACKGROUND Honey has been familiar to possess antimicrobial potential to clear infection against burn wound infecting bacteria since ancient times. The objective of the study was to evaluate the efficacy of the newly formulated honey ointment during the treatment of burn wound infections. The Experimental (Non comparative) study was conducted at outpatient department of Dermatology, Fauji Found...

Honey and hydrogen peroxide are effective antibacterial agents. The antibacterial activity of honey is mainly attributed to hydrogen peroxide generation that is produced in the honey by the activity of the glucose oxidase (GOX) enzyme. Ziziphus Spina Christi and Acacia spp. honey samples were collected for the study. Hydrogen peroxide was measured using a sensitive enzymatic/colorimetric assay....

Fifty samples of honey collected from local markets of Portugal and Spain during year 2002 were analyzed for 42 organochlorine, carbamate, and organophosphorus pesticide residues. An analytical procedure based on solid-phase extraction with octadecyl sorbent followed by gas chromatography-mass spectrometry (GC-MS), for organochlorines, and by liquid chromatography-atmospheric pressure chemical ...

Volatile organic compounds of Amorpha fruticosa honey samples were isolated by headspace solid-phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE), followed by gas chromatography and mass spectrometry analyses (GC, GC-MS), in order to obtain complementary data for overall characterization of the honey aroma. The headspace of the honey was dominated by 2-phenylethanol (38.3-5...

Traditionally, melissopalynological and physicochemical analyses have been the most used to determine the botanical origin of honey. However, when performed individually, these analyses may provide less unambiguous results, making it difficult to discriminate between mono and multifloral honeys. In this context, with the aim of better characterizing this beehive product, a selection of 112 Lava...
