Název v původním jazyce

Quality evaluation of blossom honeys obtained from the market of the Czech Republic

Popis výsledku v původním jazyce

The aim of the study was the quality evaluation of blossom honeys from the market in the Czech Republic. The analysis was conducted on 46 samples of blossom honeys including basic physico-chemical parameters proposed by Regulation: water content, electrical conductivity, acidity, the content of 5-hydroxymethylfurfural (HMF), diastase activity and pH value. It was found that all examined honey samples were in accordance with Decree no. 76/2003 Coll. and didn't exceed limits for water content, electrical conductivity and acidity. Oppositely, exceeded limits were observed for HMF (< 40 mg/kg) and diastase activity (> 8 o Schade) in 4 and 6 samples, respectively. Out of 46 analyzed samples 17 % (8 samples) didn't fulfill Regulation requirements. Although, according to more strict Czech standards (ČSV 1/1999 - Český med) 52 % of samples (24) would be declared as inadequate, due to lower allowed HMF maximum limit (< 20 mg/kg). The results are emphasizing the necessity for more frequent inspections of honeys present in the market of the Czech Republic by supervisory authorities, especially HMF content should be checked more often.
