Microwave drying removed a large part of
“Earthy-musty” off-odour, and marinating with Vc or TP help to remove this off-odour. The slices dried
with microwave or MV had less thiobarbituric acid reactive substance (TBARS). The TBARS decreased
with power intensity during microwave drying but increased with the vacuum during MV drying. All
drying processes largely decreased the contents of fat, EPA and DHA (P < 0.05). Microwave drying
retained more fat (P < 0.05). The Vc and TP protected the EPA and DHA effectively.
