In this week's unit, you will determine Solids content of the mash. Solids and the concept of solids analysis in mash can be demonstrated by subtracting the percent loss of moisture using a digital scale and a oven. (Bake for 3 hours at 105 degree Celsius).

You will have hands-on experience determining Solids content and operating the Cook process on the Ethanol Training Simulator.

For this week's lab report explain the importance of knowing the Solids content of the mash.
