Read change over equal intervals
The illustrative table follows the alkaline milk and lipase model for 180 seconds. All samples start at pH 9.0, so their final readings can be compared alongside their changes. The largest fall occurs at thirty degrees Celsius in this example. This supports faster acid production within the tested range. It does not prove that higher temperatures always give faster reactions, or that the model measures the number of microorganisms.
