PH is a measurement used in chemistry to determine the acid or base levels in a solution. The method uses a number scale to determine pH balance, with 7 being neutral. PH balance can be measured by using test-strip kits that can be found in drugstores, hardware stores and department stores, and contain litmus paper strips with a chart that indicates pH levels by color and number. In humans, saliva or urine would be the test samples. For solids such as foods, they must be made fluid.
Step 1
Mix one part solid food with equal or lesser parts water in a blender. Test strips need a solution to be water-based to give a reading, and the pH of purified water is neutral, so this wont affect the balance of the food itself. Blend these until they reach a smooth liquid consistency. Pour in a cup or small container once blended. Let the solution sit out and reach an average room temperature of about 77 degrees Fahrenheit, as cold or hot temperatures can alter readings.
Step 2
Dip a test strip into the solution for a few seconds, then remove it.
Step 3
Observe the color of the test strip and match it with one of the colors on the chart that comes with the kit. Any value less than 7 is considered acidic, and any value above 7 is basic. The test strips might not give pinpoint measurements of pH, but will give a sufficient idea of the pH levels in foods.
