Aquafaba or chick pea water is the liquid leftover from cooking chick peas and it makes a great foam. Chickpeas like other legumes or beans contain proteins and saponins. The combined presence of these substances in chickpea liquid means that, when agitated and air is added to the mixture, it will produce a foam.
The white foam is a 'scum' that is formed as protein is released from the chickpeas. Yes, that is the term that is used. Scum. This can be skimmed for aesthetic reasons - it sticks to the pot, or overboils, etc...
What Is It? Aquafaba is the thick liquid that results from soaking or cooking legumes, such as chickpeas, in water for an extended period of time. It's the translucent viscous goop you probably rinse down the drain when you open a can of chickpeas.
Rinsing Banza after cooking removes the chickpea starch that forms during the cooking process. Some tips to decrease the foam: fill your pot with more water, turn the burner down to a lower heat, add a splash of olive oil to the water, and/or scrape some foam off the top with a spoon.
How can you tell if dried chickpeas are bad or spoiled? The best way is to smell and look at the dried chickpeas: if the dried chickpeas develop an off odor, flavor or appearance, or if mold or insects appear, they should be discarded.
Canned chickpeas can be stored indefinitely. The dried version should be stored in a tightly closed container at cool room temperature. Use them within 6 months. Leftover cooked chickpeas will keep for 3-4 days in the refrigerator, stored in a tightly closed container.

And it is completely safe to taste, making it perfect for littles. (If you are looking for more taste-safe options you have got to read this–> Taste-Safe Sensory Play Ideas.)
The foam happens because legumes are rich in saponines (see my longer answer here). It contains nothing more and nothing less than the water in which you boil the beans, it just happens to trap air bubbles because of its physical properties. There are no specific culinary reasons for or against keeping the foam.
Pasta foams due to the accumulation of superheated starch molecules that are found in the pasta. The white foam forms bubbles that trap hot vapor, preventing it from escaping the pot. The boiling pot of water and pasta then becomes superheated if left unstirred, or the frothy layer is not skimmed off the top in time.
“The foam that appears on dried beans when they are cooked is made up of excess starch and protein that dissolve from the beans when cooked,” says Diana Orenstein, a registered dietitian with Newton-Wellesley Hospital.
You may notice some white foam on the top of the water after soaking. This is excess starch and impurities that rise to the top. Unless you skim this off, it is likely to get trapped between the beans during straining. Rinsing them (while stirring them around) helps make sure that this gets removed.
However, if the foam bothers you, you can reduce its formation by adding a tablespoon of oil or lard to the pot when you put it on to cook. Onion, garlic, herbs, and spices can be added to the pot at any time. Their flavor will be more pronounced as added when beans are almost cooked.
It's called aquafaba, and it's (basically) free! When we refer to aquafaba (as we often do in our cookbook on vegan cooking, Vegan for Everybody), we're talking about the liquid in a can of chickpeas. (We're not talking about the liquid in a can of any other beans.
While roasting chickpeas uses less oil, the chickpeas take a long time to cook and the insides dry out before the outsides have become sufficiently crispy. This can leave the chickpeas with a mealy, unpleasant texture.
If you are using canned chickpeas, drain and rinse them with water to cut the sodium (salt) content by almost a half. Rinse well in cold water to make them easier to digest and less gas-producing.
Two signs that your beans have soaked for too long is if you see bubbles collecting on the surface of the water, or you notice an off or sour smell.
Powdery mildew, caused by the fungal organism Erysiphe polygoni, is one of the most commonly occurring diseases on many types of beans.
Today, a quick poll of our test kitchen staff confirmed that this early soup wisdom still stands: Soup scum should be skimmed off and discarded.
You can eat canned chickpeas straight out of the can! (Just be sure to rinse them off before chowing down to wash out excess sodium) Otherwise, you can roast them or turn them into any number of delicious dishes, like these here.
Chickpeas are usually sprayed with glyphosate, not necessarily to kill weeds, but to dry out crops to make them easier to harvest. And, if the crop is too wet when the herbicide is applied, they can soak it up and leave a residue on the garbanzo beans themselves.
The consistency is so thick it's more like a heavy cream rather than a creamer substitute. Regardless, it froths up well and is very creamy. The almond taste is noticeable but the creamer isn't bitter or grainy.
Not rinsing the beans first.
Not only is this liquid extra starchy, but it's also usually full of sodium. Unless a recipe specifically calls for using this liquid, it won't be a welcome addition to your dish.
Bring the water to a boil, then turn the heat down and simmer the chickpeas for 45 mins (if you are going to cook them further in another dish) or up to 1 hour. Taste to see if they are tender.
I have also been getting another question which is “are canned chickpeas cooked?” Yes, they are already cooked and ready to eat! You'll just need to drain them and rinse before you use them for your recipe.
