About this document

pH Guidelines for Safe Canning by Mary Chaney is a document available to read on EtoBox.

This document discusses the importance of food pH levels in commercial canning operations. It explains that pH measures the concentration of hydrogen ions in a food, with lower pH indicating higher acidity. Microorganisms are sensitive to pH levels, and very low or high pH prevents their growth. For canning, the key pH cutoff is 4.6 - foods above this are considered low-acid and require pressure cooking to kill spores, while high-acid foods below 4.6 only need pasteurization heating in a water bath.
