ABSTRACT
Button mushroom (Agaricus bisporus) slices as well as whole mushrooms were dried by microwave-vacuum drying technique to a moisture content of around 6 %(d.b.). The dehydrated mushrooms were compared with hot-air dried products on the basis of different quality attributes such as colour, texture, rehydration ratio and sensory score. Statistical analysis of data revealed significant difference among the drying methods for all the attributes at p ≤ 0.05. Microwave-vacuum dried mushrooms had significantly higher rehydration potential, lower density, better colour and softer texture than those obtained by air drying. The microwave-vacuum dried mushrooms were rated much better than air dried products by a sensory panel in terms of appearance, color and overall acceptability.
