"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.

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.
