Mrs. Wages Powdered Citric Acid - 12 oz.

Adding citric acid to home canned goods raises the acidity and lowers the pH of the contents of the jar. This helps to reduce spoilage. The USDA recommends the addition of citric acid to each jar of canned tomatoes to reduce potential botulism risk. Citric acid will increase the acidity of home canned tomatoes when prepared by the boiling water process.
