In reality the foam is not bad, but is merely the water from boiling too much. Normally you don't want the water to reach that point. You want to keep it boiling at a constant rate. Never do this when it's fully boiling, but all you have to do is mix it lightly so that it can dissolve because you are not even supposed to mix it while the beans are cooking which is the reason why it shouldn't go to the extent that foam is created. In short, the foam is just a chemical reaction that will not do any harm.
Beans change colors while cooking them because of heat. The pigments inside the beans keep changing colors that way. Hope I helped! =)
By using Beano drops (an enzyme) or by soaking them overnight before cooking.
If you are cooking the beans after you snap them, you can keep them from oxidizing by dipping them in a solution of 1 tablespoon lemon juice to 1 cup cold water.

To efficiently transition from using dried beans to canned beans in your cooking routine, simply rinse and drain the canned beans before using them in your recipes. Adjust the cooking time and seasoning as needed, as canned beans are already cooked and may be softer than dried beans. Start by substituting canned beans in your favorite recipes and gradually incorporate them into your cooking routine.
Beans can soak for at least 4 hours or overnight before cooking to help soften them and reduce cooking time.
Soak beans in the fridge for at least 8 hours before cooking them.
Soaking beans overnight is important for optimal cooking results because it helps to reduce cooking time, improve texture, and make the beans easier to digest.
Perhaps it starts foaming ( carbon dioxide) if your 'cooking' meal is acidic (e.g. vinegar) and when heated.
To quickly soak beans for cooking, rinse them thoroughly and then cover them with water in a pot. Bring the water to a boil, then turn off the heat and let the beans sit in the hot water for about an hour. Drain and rinse the beans before cooking them as usual.
To properly soak beans overnight for optimal cooking results, rinse the beans thoroughly and place them in a large bowl. Cover the beans with water, making sure there is at least 2 inches of water above the beans. Let the beans soak overnight at room temperature. Drain and rinse the beans before cooking them the next day.
To quickly soak black beans before cooking, rinse them thoroughly and then cover them with water in a pot. Bring the water to a boil, then remove the pot from the heat and let the beans soak for about 1 hour. Drain and rinse the beans before cooking.
