资料摘要:
Dried apples are one example of desiccated fruits that
enjoy a certain popularity in the snack foods market and
the processed foods industry. Crispness is maintained at
low water content and low humidity levels. The United
Nations standard UNECE DF-16[1] requires that the
moisture content of whole dried apples be less than 22%
for example.
The rate at which desiccated foods reabsorb moisture
from the atmosphere is important to both the packaging
industry and to storage facilities. One might anticipate
that the rate of rehydration is a function of accessible
surface area, that is, the size of the pieces of apple. This
simple study clearly demonstrates that behavior.
