How to De-Gas Beans. What Works and What Doesn’t

Do you love beans, but they don’t—er—love you? Beans are delicious, nutritious, and cheap, which makes them great for so many reasons. However, they cause gas (aka flatulence or tooting), which is isn’t so great.

Thankfully, I’ve learned how de-gas beans easily to improve your digestion and your relationships! I’ve tried a bunch of methods and I know what works–and what doesn’t.

You know how it goes: beans beans the musical fruit. Well, there’s nothing magical about stinking up a room. But what is magical is that once you learn how to degas beans, the stinky music actually stops.

When I say that I know how to de-gas means, I mean it.

We used to be vegan and ate a lot of beans. We aren’t vegan now, but we cook a HUGE pot beans in our large pressure cooker several times a week.

Benefits of Beans

Just in case you wondered why adding more beans to your diet is a good thing to consider, here are some great reasons.

Nutrition powerhouses

Beans are very high in fiber, protein and complex carbohydrates.

Cheap, cheap cheap

Even the price of heirloom organic beans pales in comparison to that of meat.  Now, I am not saying that you shouldn’t eat meat, but beans sure can help you stretch your food budget.

And who doesn’t need a bit of stretch these days?

Long shelf life

In these days of concern about inflationary food prices with folks storing up food for leaner days ahead, beans are a logical choice.  They may take longer to cook as they age, but they do not spoil.

Why Do Beans Cause Gas?

There are two reasons why beans cause flatulence (otherwise affectionately known as gas). We actually called this “poohstinkies” in my family, but that’s beside the point.

Fiber

Beans are high in dietary fiber, which is mostly soluble fiber. Soluble means it dissolves in water. The fiber absorbs water in your digestive tract to form a thick substance.

Fiber is known for its health benefits, but if you increase your fiber intake too quickly, you can end up with (you guessed it)–intestinal gas and bloating.

When dietary fiber makes it to the colon, it’s fermented by beneficial bacteria there and gas is produced.

Raffinose Oligosaccharides

Beans also contain oligosaccharides, specifically the raffinose family. They are sugars that are also found in cruciferous vegetables like cabbage, broccoli, and Brussels sprouts. Alpha-galactosidase is an enzyme that digests these sugars, but since it’s not that prevalent in the human digestive tract, you get gas when you eat them.

For the same reason, if any food ends up in the large intestine without being digested, it can cause gas as well.

The enzyme is derived from the fungus Aspergillus niger and is sold as Beano as well as under other names.

If you don’t want to spend a huge amount on Beano, you definitely need these de-gassing tips.

Side note, there’s an article online stating that we get gas from eating beans because we don’t have an enzyme that the beans contain. That makes no sense at all. We don’t have much of an enzyme to digest what beans have in them. 

Does Baking Soda Degas Beans?

Well, yes, but there can be a big problem with this method.

There are some who claim that baking soda  doesn’t work and that it only changes the pH of the cooking water. Others say that changing the pH of the water reduces the amount of raffinose in the beans.

In my experience, it’s true that a little baking soda works to degas beans. However (and this is a BIG however), you will end up with VERY mushy beans.

I mean seriously mushy especially if you cook them in a pressure cooker. Sometimes mushy beans are great (for refried beans, this bean dip, or this savory hummus,) but not so great for chili or bean salad.

How Much Baking Soda Do You Need to Degas Beans?

If you’d like to try the baking soda method, you can. As mentioned, if you’re cooking your beans in a pressure cooker or Instant Pot, just be prepared for some mushiness.

Simply add 1/4 teaspoon baking soda to the cooking water for every pound of dried beans and cook as usual.

How to De-gas Your Beans

Here are my very well tested tips for perfectly de-gassed and non-mushy beans. It’s actually a full court press against bean gas. You can do any of these and it will help, but doing all of them is pretty much guaranteed to give you gas-free beans.

These are the basics. Make sure to read the recipe card below for more details.

Spices That De-Gas Beans

There are a number of spices that work to de-gas beans. Here are some that work the best. We used to use ajwain and epazote all the time, but more recently have used ginger and fennel. They all work great.

• ajwain
• epazote 
• ginger
• cumin
• fennel
• asafoetida
• kombu (This isn’t a spice, but it can work well too. You’ll want to put about a 2 inch piece of dried kombu seaweed in the pot with the beans. It’s more costly than other options, however.)

Now, here are some more detailed instructions about how to get the toot factor out of your beans.

Can You De-gas Canned Beans?

To reduce the effects of gassy components from canned beans, rinse the beans twice before using them in a recipe. It’s not as effective as de-gassing dried beans, but it canhelp.
