EFFECT OF MICROWAVE VACUUM DRYING ON PROTEIN AND CHLOROPHYLL CONTENTS OF BLIND NETTLE (Urtica urens L.)
Get PDFThe effects of time, energy, and operational mode of microwave drying on the protein
and chlorophyll contents of blind nettle extract were studied. Comparison of the modes
showed that drying was faster in the normal than in the impulse mode. The kinetics
of water loss followed a saturation-type behaviour. A virtual but significant increase in
protein concentration was observed for the normal-mode, 300 W treatment. A constantly
high energy input for a long time might damage proteins through the Maillard reaction.
Normal-mode technique did destroy part of the chlorophyll content. It was concluded
that the faster the drying, the more chlorophyll remained
