Canola flower honey solution and glucose/fructose solution were subjected to ultrafiltration
(UF) coupled with diafiltration (DF) with the use of 15 kDa ceramic membrane in order to par-
tially remove sugars (with the rejection of proteins at the same time), and enhance a subsequent
spray drying process. Membrane processing affected honey solution chemical composition,
what was confirmed by Fourier transform infrared spectroscopy ‐ATR spectroscopy analysis.
50% of sugars was removed from honey solution, while 74% of nitrogen‐based compounds was
rejected by membrane. Honey pretreatment by UF/DF enhanced the yield of subsequent spray
drying process with the application of gum arabic as a drying carrier. Obtained powders, con-
taining 60% of honey solids were fully amorphous (verified by morphology observation and X‐
ray diffraction), with physical properties typical for sugar‐rich material dehydrated by spray dry-
ing. It was possible to reduce carrier content in honey powder to 40% solids, with a mainte-
nance of drying yield above 50% at the same time. However, the flowability was not enhanced
because of UF/DF pretreatment (but it was also not deteriorated).
