cranberries (Vaccinium macrocarpon) were dried using microwaves
(MW) under subatmospheric pressure. Two MW modes were tested (continuous
and pulsed), two combinations of pulsed MW mode (30 sec on/30 sec off,
30 sec on/45 sec off) and three MW power levels (1.00, 1.25 and 1.50 W
g-1 of initial sample mass). Three vacuum levels were compared
one to another (3.4, 18.6 and 33.8 kPa of absolute pressure). Several
process and quality parameters such as time of drying, colour, toughness
and rehydration ratio were measured and calculated in order to evaluate
different drying conditions. Methods with higher overall MW input (1.25
and 1.5 W g-1) and longer power-off time (45 sec) combined
with high vacuum (3.4 kPa) offered high quality dried berries (colour
parameters similar to those of fresh fruit, soft and chewable texture,
juiciness and good rehydration properties).]]>Beaudry, C., G.S.V. Raghavan and T.J. Rennie,20032117971810Beaudry, C., G.S.V. Raghavan, C. Ratti and T.J. Rennie,200422521539Chen, S.D. and E.M.
