Began milk pH testing. pH tests will occur every four hours between the times of 8:30 AM and 4:30 PM until consumer acceptance level reaches spoiled.
Consumer acceptance will be based off of three non-iGEM team members recommendations.
A digital pH meter was used in the experiments and calibrated before each series of tests.
Three milk samples were tested to account for variability.
Initial pH tests conducted at 12:30 PM.
Sample 1: 6.79
Sample 2: 6.79
Sample 3: 6.79
Probe Calibrated in pH 4.0 and pH 7.0 buffer solution prior to sample 1 reading.
