The phenolic composition, aroma compounds, and organic acid content of 83 vinegars have been determined. Multivariate analysis techniques have been used to classify these vinegar samples according to raw material (white wine, red wine, apple, honey, alcohol, balsamic, and malt) and production process (with and without aging in wood). Cluster analysis grouped the samples according to production ...

BACKGROUND The interaction between ionizing radiation and substances in cells will induce the production of free radicals. These free radicals inflict damage to important biomolecules such as chromosomes, proteins and lipids which consequently trigger the expression of genes which are involved in protecting the cells or repair the oxidative damages. Honey has been known for its antioxidant prop...

Bees have been managed and utilised for honey production for centuries and, more recently, pollination services. Since the mid 20th Century, the use and production of managed bees has intensified with hundreds of thousands of hives being moved across countries and around the globe on an annual basis. However, the introduction of unnaturally high densities of bees to areas could have adverse eff...

In the trend of the use of antimicrobial compounds from natural and renewable resources, natural antimicrobial compounds, particularly found in food and with potential biomedical applications, are of highest interest. In this context, the contribution by Brudzynski et al. to our special issue on “antimicrobial compounds from natural sources” deserves a special attention not only for giving insi...

BACKGROUND Multidrug resistance is a global health issue. Hence integration of traditional medicine like honey and modern medicine could be a best option in the treatment of patients infected with drug resistant bacteria. Despite the multi floral and huge honey production in the region, there are no studies that evaluate the antibacterial activity of honey against multidrug resistant bacteria. ...

This study investigated the potential of Rhizopus arrhizus UCP 402 for producing chitosan using corn steep liquor and honey as agroindustrial nitrogen and carbon sources. A complete factorial design was used to assess the improved biomass and chitosan production. The results were evaluated using Pareto charts (Statistica 7.0 software). The chitosan obtained was characterized by X-ray diffractio...

objective(s):previous studies demonstrated a functional similarity between vertebrate and honey bee nervous systems. the aim of the present study was to compare the effects of heroin and iranian street kerack, a combination of heroin and caffeine, on sensory threshold and locomotor activity in honey bees. materials and methods: all drugs were given orally to honey bees 30 min before each experi...

In order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in Isfahan region. Protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and Pollen. Results showed that the longevi...
