Why are potatoes wet inside?
As potatoes bake, their starch granules soften in the heat and absorb the surrounding moisture. As they increase in size and often burst, granular particles separate from one another, making the texture of the potato mealy and fluffy. However, if moisture is trapped inside the skin, it can make the potato quite soggy.

The amount of water is determined by subtracting the dry weight from the initial weight, and the moisture content is then calculated as the amount of water divided by the dry weight or total weight, depending on the reporting method.
How do you measure moisture content?
The primary methods used are loss on drying and Karl Fischer titration. Loss on Drying. In this method, a wet sample is weighed on a balance, placed in an oven, and heated until the end of the drying period, i.e., until the sample reaches equilibrium. The weight loss is the moisture content of the sample.
