What is the percentage moisture content on a wet basis for a potato with a moisture content of 400% on a dry basis?

To determine the percentage moisture content on a wet basis for a potato with a moisture content of 400% on a dry basis, it's important to understand the definitions of moisture content on both the dry and wet basis.

Moisture content on a dry basis refers to the weight of water present in a substance compared to the weight of dry matter. When we say a potato has a moisture content of 400% on a dry basis, it means that the weight of the water is four times the weight of the dry material in the potato.

To convert this to the wet basis, we use the following formula:

Moisture Content (wet basis) = (Weight of Water / Total Weight) × 100

First, let's establish our variables. If we assume the weight of dry matter is 1 unit:

• Weight of Water = 4 units (since moisture content is 400% on a dry basis)
• Total Weight = Weight of Dry Matter + Weight of Water = 1 unit + 4 units = 5 units

Now we can calculate the moisture content on a wet basis:

Moisture Content (wet basis) = (4 units / 5 units) × 100 = 80%

This calculation demonstrates that the
