Water loss and solid gain of sweet potato slices increased
with time. A high initial rate of water removal and solid gain,
followed by a slower removal (and gain) in the later stages
was observed. Several research groups have published similar curves for osmotic dehydration of foods (COLLIGNAN;
RAOULT-WACK, 1994; KAYMAK-ERTEKIN; SULTANOGLU,
2000; PARK et al., 2002).
