During FD, 5 h was adopted for the sublimation
period followed by a desorption period (Pei, Yang et al., 2013).
During FD, samples were randomly taken at 1, 3 and 5 h for analysis
and the moisture contents of these samples were
91.90 ± 0.09%, 84.43 ± 1.89% and 38.70 ± 2.06%, respectively. Samples
taken at 6.5 h and 8 h during desorption period had moisture
contents of 18.20 ± 1.07% and 4.19 ± 0.56%, respectively. The same
sampling analysis was applied for FMVD; the moisture content of
the sample was 2.74 ± 0.88% (FMVD 5.15 h).
