A food is initially at a moisture content of 90% dry basis. Calculate the moisture content in wet basis

Anvisha [2.4K]

Answer:

Moisture content in wet basis = 47.4 %

Explanation:

Moisture content expresses the amount of water present in a moist sample. Dry basis and wet basis are widely used to express moisture content.

The next equation express the moisture content in wet basis:

$MC_{wb}=\frac{MC_{db}}{1+MC_{db}}$

where, $MC_{wb}$ : moisture content in wet basis and

$MC_{db}$ : moisture content in dry basis

We now calculate the moisture content in wet basis:

$MC_{wb}=\frac{MC_{db}}{1+MC_{db}}$

$MC_{wb}=\frac{0.90}{1+0.90}$

$MC_{wb}$ = 0.474 = 47.4 % wet basis

Have a nice day!
