- The process of canning and cooking is not the same process. Canning preserves food by stoping spoilage and controlling the following:
- growth of undesirable microorganisms-bacteria, molds, and yeasts,
- the activity of food enzymes, reactions with oxygen, moisture loss.
- Reputable Recipes: When canning, it is important to use reputable and tested recipes. Recommended sources included:
Forms of canning
- Pressure Canning: The pressure canning process must be used to can all
low acid food (pH greater than 4.6) which includes vegetables, meats, poultry, seafood, soups, and other mixtures of both acid and low acid ingredients. An example of such a mixture would be spaghetti sauce with tomatoes, meat, and vegetables.
- Waterbath Canning: The water bath process is used to can all high acidfoods (pH less than or equal to 4.6) which includes most all fruits. However, tomatoes,safety of the recommended process. This process is used to can pickles, relishes, fruit spreads and salsa with acid added.
- Clostridium Botulinum/ Botulism Poisoning: The bacterium Clostridium Botulinum is destroyed in low-acid foods when they are processed at the correct time and pressure in pressure canners. Using boiling water canners for these foods poses a real risk of botulism poisoning. If Clostridium botulinum bacteria survive and grow inside a sealed jar of food, they can produce a poisonous toxin. Even a taste of food containing this toxin can be fatal.
- Equipment: Proper equipment is essential to preserving a safe product. When canning the following are brief recommendations:
- Always use canning jars and lids when preserving canned products.
- Reusing glass commercial product jars such as used spaghetti sauce, jelly, or pickle jars is not recommended. Such jars can burst under pressure, as they are not designed for home canning.
