Citric acid is used to preserve color in low acidic fruits, but it's main function is to raise the PH level (acidity) to make it impossible for botulism to occur in your finished product. It is absolutely essential that you add acid of some kind to low acid foods you are canning. Botulism is deadly. You may use citric acid (vitamin C), lemon juice, ascorbic acid or vinegar. Always use a recipe to get the proportions right. As to how it is used, it depends on what you are making. With jams, jellies and sauces you simply mix it in during or before the cooking process. If you are preserving whole fruits/tomatoes you add it directly to each jar. If you are preserving whole fruits in syrup, mix it into the syrup. Canning is a fun hobby, but is not to be done haphazardly with directions posted by who-knows-who. That can lead to a dangerous situation. The Ball Blue Book of Preserving is widely accepted as the best authority on home canning.
