 +Besides the kiwi, all other types of food tested showed visible signs of dehydration. In the case of the cherries, mushroom, and bananas, these signs were significant. In the case of the apples, the drying process is about half-way done, as expected, according to Table {{ref>typeoffood}}. The reason the kiwi hadn't yet shown much change is due to the fact that kiwi is made at 83 % of water.
