Stability of volatile compounds of honey during prolonged storage.

The aim of the study was to identify, via headspace solid phase microextraction and gas chromatography-mass spectrometry, volatile compounds in eight no processing L. honey samples produced in the state of Santa Catarina, Brazil, and monitor their stability over 540 days of storage at 20 ± 4 °C, searching for possible degradation indicators compounds. The result of the initial analysis showed the presence of 32 volatile compounds and 24 were selected for the evaluation of the behavior over the storage.

Honey: Chemical composition, stability and authenticity.

The aim of this review is to describe the chemical characteristics of compounds present in honey, their stability when heated or stored for long periods of time and the parameters of identity and quality. Therefore, the chemical characteristics of these compounds were examined, such as sugars, proteins, amino acids, enzymes, organic acids, vitamins, minerals, phenolic and volatile compounds present in honey. The stability of these compounds in relation to the chemical reactions that occur by heating or prolonged storage were also discussed, with increased understanding of the behavior regarding the common processing of honey that may compromise its quality.
