You are preparing soft maize porridge at home using the following procedure: 1) the maize meal is suspended in cold water, 2) it is added to a pan with boiling water and brought to the boil, 3) it is cooked on the stove for 20 minutes while stirring continuously, 4) after cooking the porridge is removed from the stove and cooled to room temperature, 5) it is then stored it the refrigerator until the next day. Explain the chemical, physical and viscosity changes that starch in the maize meal and porridge undergoes during each stage of the process
