From Seed to Shelf: The Canning Process
Understanding the canning process helps appreciate the longevity and safety of canned beans.
- Cleaning and Soaking: Beans are thoroughly cleaned and often soaked to rehydrate them.
- Blanching: Briefly blanched to soften the skins and inactivate enzymes.
- Filling: Beans are filled into cans along with water or a brine solution.
- Sealing: Cans are hermetically sealed to prevent spoilage.
- Retorting: The sealed cans are heated under pressure (retorted) to kill any microorganisms.
- Cooling: Cans are cooled rapidly to prevent overcooking.
- Labeling and Storage: Finally, cans are labeled and ready for distribution.
Common Mistakes to Avoid When Using Canned Beans
While canned beans are convenient, there are a few pitfalls to avoid to ensure the best flavor and texture.
- Skipping the Rinse: Rinsing canned beans removes excess sodium and phytic acid, which can inhibit nutrient absorption.
- Overcooking: Canned beans are already cooked; adding them too early in a recipe can make them mushy.
- Ignoring the Liquid (Aquafaba): The liquid in canned beans, known as aquafaba, is a valuable ingredient, especially for vegan baking. Don’t just throw it away!
- Not Seasoning: Even though some canned beans are flavored, they often benefit from additional seasoning to enhance their taste.

Frequently Asked Questions (FAQs)
Are canned beans as nutritious as dried beans?
While some nutrients may be slightly reduced during the canning process, canned beans are still an excellent source of protein, fiber, and essential vitamins and minerals. The difference in nutritional value is often negligible, especially when considering the convenience factor.
Do I need to drain and rinse canned beans?
Yes, it is generally recommended to drain and rinse canned beans before using them. This helps remove excess sodium and phytic acid, a compound that can inhibit nutrient absorption.
What is the shelf life of canned beans?
Canned beans can last for several years if stored properly in a cool, dry place. Check the “best by” date on the can, but unopened cans are generally safe to consume well past that date.
Are BPA-free cans better?
BPA (Bisphenol A) is a chemical used in the lining of some cans. While research on the health effects of BPA is ongoing, many consumers prefer BPA-free cans as a precautionary measure.
Can I eat canned beans straight from the can?
Yes, canned beans are pre-cooked and safe to eat directly from the can. However, they may taste better if rinsed and heated.
What types of beans are most commonly canned?
Commonly canned beans include kidney beans, black beans, pinto beans, cannellini beans, and garbanzo beans (chickpeas). Many other varieties are also available in canned form.
Are flavored canned beans a good option?
Flavored canned beans can be a convenient option, but be mindful of the sodium and sugar content. Read the nutrition label carefully before purchasing.
Can the liquid from canned beans be used in recipes?
Yes, the liquid from canned beans, known as aquafaba, can be used as a vegan egg substitute in baking and other recipes. It’s particularly effective for making meringues and mousses.
How should I store leftover canned beans?
Leftover canned beans should be stored in an airtight container in the refrigerator and used within 3-4 days.
Are organic canned beans worth the extra cost?
Organic canned beans are grown without synthetic pesticides and fertilizers. Whether they are “worth it” depends on your personal preferences and budget, but they offer a more environmentally friendly option.
Can canned beans cause gas?
Beans contain oligosaccharides, complex sugars that can be difficult to digest, leading to gas. Soaking dried beans before cooking and gradually increasing bean consumption can help reduce this effect. While canned beans are pre-soaked, some individuals may still experience gas.
What is the best way to add flavor to plain canned beans?
Experiment with different herbs, spices, and seasonings to enhance the flavor of plain canned beans. Consider adding garlic, onion, cumin, chili powder, oregano, or smoked paprika. A squeeze of lemon or lime juice can also brighten the flavor.
