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:

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

The next equation express the moisture content in wet basis:  

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

<em>where,  MC_{wb}: moisture content in wet basis and  </em>

<em>              MC_{db}: moisture content in dry basis    </em>

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!
