Weekly Report 10/2

Today, all the members of the group are present. The experiment was tested on Wheat Gluten. The group was assigned to form a gluten ball.

The basic formula will be:

Gluten ball
110g flour
60ml water


The manipulated variable will be the type of flour: all purpose flour, cake flour,and bread flour. The first one to be tested out was all-purpose flour.  Procedure on how to make a gluten ball was the same for the other two flours.


2.30 pm: Initializing the experiment
Description:
 It all started with using a fork to stir the dough that forms as the water was added



and then kneading the dough as it turned into a ball


After a dough ball was formed, it was wrapped with a muslin cloth


When the dough ball was safely wrapped with the muslin cloth, it was washed under a rapid running water. The main purpose if this action is to wash out all the starch, with only the gluten as the remaining. The task is considered done when the water that is being squeezed out comes out clear. The kitchen has a bad water flow so it took some time to wash out all the starch.










What gluten looks like





Finally, after all the starch were washed away, this was how how the results looks like:

cake flour



All-purpose flour



Bread flour




3.45 pm: Starts Baking
Description:
