Abstract
The main objective of this study was to evaluate and compare two different drying methods of guava fruit (Psidium guajava L.) - atmospheric and subatmospheric, both involving microwaves (MW) as an energy source.  This paper entails three components – MW and hot-air drying of guavas, MW and vacuum dryings of guavas, and comparison between these two.  Osmotically-dehydrated guavas were microwave-dried using two temperatures of hot air (33°C and 43°C), two levels of MW mode (30 seconds on/30 seconds off, 30 second on/45 seconds off) and two MW power levels (40W and 50W).  MW-vacuum part of the research tested two parameters – MW power mode (30 seconds on/45 seconds off and 30 seconds on/60 seconds off) and two power levels (50W and 60W).  in subsequent comparison, several quality parameters were evaluated using two of the better methods of drying.
