Honey 1
Parameters (quantitative): diastase number acc. to Schade [-], proline [mg/kg], hydroxymethylfurfural (CAS 67-47-0) [mg/kg], electrical conductivity [mS/cm], moisture [g/100 g], glycerin [mg/kg], ethanol (CAS 64-17-5) [mg/kg], pH value [-]
Article Number: 2010455
Description: With this proficiency testing the comparability of the chemical-physical testing of different attributes in honey can be assessed. The diastase activity serves to evaluate the grade of heating treatment. The amount of proline provides information about the ripeness and the natural purity. Hydroxymethylfurfural (HMF) develops during sugar degradation during prolonged storage and through high storage temperatures. The conductivity helps to evaluate the purity of sort honey, the pH-value and the water content are general quality markers, while increased glycerin and ethanol amounts indicate alcoholic fermentation.
