Physical-Chemical Analysis and Antibiotic Content of Polyflora Honey in Romania
Abstract
Physical-chemical analysis and antibiotic content of honey is an important factor in it’s therapeutic potential. Antibiotic content and physical-chemical analysis of polyflora honey were analyzed from 130 samples of natural honey collected in 2011 from three different places of Romania.
In this study we aimed to analyze the following physical-chemical indices: moisture, reducing sugar, sucrose, free acidity, diastatic number, HMF identification and the following antibiotics: streptomycines, tetracyclines and sulphonamides. Uncontrolled use of antibiotics is responsible for their presence in bee products and is an important problem for safety of honey as food. For this porpose we aimed to determine residues of antibacterial drugs from honey by liquid-chromatographic technique with column post-reaction and fluorimetric detector.
Test results by physical-chemical analysis correspond to Directive 2001/110/CE SR 784-2/2009 and shows the following results: moisture 16.9%; reducing sugar 81.5%; sucrose 3.06%; free acidity 2.31ml; diastatic number 13.9 cm3/g; HMF identification negative. The results for antibiotic content of Romanian honey must be absent. The physical-chemical properties of honey from Romania indicates a very good quality of it’s. Because of that we need to diversify and commercialize this honey and it can contribute to the national agriculture development process.
