To get these objectives, detailed scientific information regarding each of the unit operations involved is needed. Thus, the objective of this study was to gain as much information as possible about the initial operation of "honey+sugars” concentration. During this stage, humidity was reduced from a 29 to 0.5% and water activity from 0.86 to 0.18. At the same time, the soluble solid content increased from 51 to 81Brix. 5-Hydroxymethylfurfural increased during the heating stages and was constant during the cooling stage; however, contents were always below 40mgkg−1. Finally during this heating step, characteristic honey volatile compounds decreased their concentration, for instance acetoin, benzaldehyde, phenylacetaldehyde, and linalool oxide, while compounds arising from amino acids and sugars through Maillard and Strecker degradation reactions significantly increased, for instance furfuryl alcohol, furfural and 5-methyl furfural.
