| Popis: | The present study reports for the first time the effect of high pressure pretreatment (100–400 MPa, 10 min) on drying kinetics of ginger and its oleoresin extraction. High pressure pretreated samples were dried, powdered and solvent extracted. The increase in drying temperature (55–85°C) increased the moisture diffusivity (2.03–4.87 � 10−9 m2/s) but resulted in decrease in 6-gingerol (53.98%) and oleoresin yield (57.31%). However, high pressure pretreatment followed by dehydration (55°C) resulted in higher moisture diffusivity (2.84–6.09 � 10−9 m2/s) as well as enhanced extraction yield of 6-gingerol (34.05%) and oleoresin (28.29%). |
