2.4. Rehydration
Rehydration ratio (RR) which is a measure of rehydration
characteristics of dried mushroom slices was determined
by immersing 5 g of dried samples in distilled
water at 30 and 100 C temperatures. The water was
drained and the samples weighed at every 30 min intervals
for those immersed at 30 C and at every 2 min intervals
for those at 100 C. Triplicate samples were used. Rehydration
ratio was defined as the ratio of weight of rehydrated
samples to the dry weight of the sample.
