Approximate pH of Foods and Food products
The pH
and/or acidity of a food are generally used to determine processing requirements
and the applicability of GMP regulations for regulatory purposes. Methods and
conditions for determining the pH and acidity of foods are also summarized in 21
CFR 114.90. Methodology for pH is generally available from pH meter and
electrode manufacturers.
To assist
readers in determining the product pH levels, the approximate ranges of pH
values are complied below. Considerable variation exists between varieties,
condition of growing and processing methods, etc. Data is presented for the
edible portion of foods in their normal and natural state, unless otherwise
designated. We solicit your input to this matter. This list will be updated when
new information is available. Please contact RLin, Brecher, Spinak, or Bluhm at
301-436-2411.
