The aim of this chapter is to describe the principal families of compounds present in honey and the analytical methods employed for their analysis, as well as to review the utility of those chemical components to discriminate honeys according to their origin....
Bad storage conditions, exposure to direct heat, microbial contamination, and/or components that are decomposed by the naturally occurring osmophilic yeasts in honey cause an increase in the free acidity value [16, 17]. Free acidity of H1 and H2 honey samples was measured as 27.00 mEq/kg and...
2.5;Effect of thermal treatment Any thermal processing of honey may contribute to product quality degeneration. Uncontrolled heating of honey may modify the essential composition of honey, destroy thermolabile honey components, influences the parameter such as enzymatic activity and hydroxymethylfurfural (HMF...

11/2000 and by the values, there were determined averages, standard deviation and analysis of the main components of honey from different Brazilian states and honey from different species of bees. Stingless bees produce honey with distinguished physical-chemical quality, depending on the species. ...
The main components of C. winteranus, C. citratus and C. distans were (+)-citronellal (37.85%), trans-citral (36.12%) and geraniol (34.76%), respectively. The DPPH radical scavenging activity of the three essential oils was dose-dependent, but lower than that of ascorbic acid (IC50=(...
