Table of the pH of Foods and Food Products - to Help in Home Canning and Food Preservation

This table of the pH and/or acidity of common fruits, vegetables, grains, breads and common food products from the FDA / CFSAN is used to determine processing requirements (and the applicability of GMP regulations for regulatory purposes).

I've reproduced the list for its instructional value: I would advise that you do not assume that you can home can items simply because they have a low pH. Food safety in home canning is far more complex than that.  Properties that affect food stability and safety, like heat transfer properties and food chemistry interactions cannot be determined from pH.

For those who are curious, the 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.

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 the LACF Coordinator by phone at 301-436-2411 or email to lacf@fda.hhs.gov.

Home Canning Kits

This is the same type of  standard canner that my grandmother used to make everything from applesauce to jams and jellies to tomato and spaghetti sauce. This complete kit includes everything you need and lasts for years: the canner, jar rack, jar grabber tongs, lid lifting wand, a plastic funnel, labels, bubble freer, and the bible of canning, the Ball Blue Book. It's much cheaper than buying the items separately. You'll never need anything else except jars & lids! To see more canners, of different styles, makes and prices, click here!For more information and current pricing:
