Red Kidney Beans Split During Soak

Ugly, wrinkled and split beans

Ugly, wrinkled and split beans

I put them in a pot with water (with about 2 tsp of baking soda) to soak overnight and only after a couple hours I found many of them with wrinkled, skins peeling off and split in half. I am going to have to toss them out as they were to be used in a salad and I want them to look appealing!

The packaging said they would be good for several more months past this date. I opened another package that has a shorter expiration date and shortly after adding water (plus a couple tsp. of baking soda) I am noticing some of the beans are beginning to repeat the same thing.

Am I doing something wrong? I am about to throw in the towel and go out and buy them in a can!
Thank you!

Sassy Sez: Oh Linda, my darling, look at your poor little split kidney beans. How frustrating. :(

My first thought would be that your beans are too old. But you seem to be using fairly fresh beans, especially if you have purchased them in a package with a use-by date.

So the other thought? It's the baking soda. But this, I have discovered, is a topic that is causing some confusion out there: Should you add baking soda to the water when soaking your beans?

Personally, I have never used this method. Some people swear it makes the beans softer and more digestible. Others say it can make your beans soft and mushy and mealy, AND can remove important nutrients from your beans.

So which is correct?

THAT is the million dollar question. My personal guess would be that it depends on the bean.

Someone might cook a batch of beans at home that are particularly old, so adding the baking soda to the soaking water works beautifully to soften them.

Others might cook a batch of beans that are very fresh, so adding the baking soda to the soaking water could ruin those (relatively) more tender skins.

My advice would be to try soaking your beans without the baking soda to see if that solves the problem.

If you are worried about the digestibility of your beans after they are cooked, add a 1-2" strip of kombu (seaweed) to the cooking water. This also adds some important nutrients to the beans and bean cooking water.

Let's open this up to discussion. What say you Vegan Coach peeps out there? Do you successfully soak your beans with baking soda? Have you experienced beans splitting when soaking with baking soda?

Inquiring minds want to know. ;)

beans splitting
by: Linda

As a horticulturist, reading that the beans splitting was a troublesopme problem made me chuckle. To me that is just evidence that these beans have done what all viable seeds (and beans) should do... absorb water to start germination. When the outer seed coat (testa) is very dry it does not swell as readily as the bean inside, so as the inside of the bean absorbs water, the testa splits off. The two sections inside are called cotyledons and these will also grow apart with the added water prior to the first little root growing.

I would suggest a shorter soak is all that's needed to keep the seed firm and full without splitting.

Splitting beans
by: Anonymous

Thank you for your information regarding the splitting beans! I think that adding the baking soda may have contributed to the splitting as well. The photograph shows this taking place in less than two hours. After soaking over night, the beans plumped up with the water, but split completely after cooking.
I did go out and purchased canned beans for my salad in the end. Next time I will omit the soda and go for a shorter soaking period!

Cool!
by: Sassy

Linda from Australia, thank you so much for your input. I love that you contributed your professional viewpoint to our bean discussion. Thanks again.

I find it interesting that these beans split like this after only two hours. Do you find that odd?

p.s. To Linda, the original poster with the follow-up comment, did you try your experiment without baking soda and a shorter soak? Curious how that all went down. xo!

Mine did the same

I just soaked some kidney beans for several hours and then split also....could be old, but though they had a very long shelf life.....

splits!
by: MyDarlin

After reading this page about 2 weeks ago, I decided to save money and cook my own. I bought red kidney beans in bulk at Whole Foods a week ago. I began soaking them today and they all split open after 3 hours of soaking. =(

they all split!
by: carina

ı am planning to cook red beans today but guess I need to find something else to cook for dinner. Early in the morning I soaked a small amount of beans and after two hours they were all open! As I read on your web site that 8 hours of soaking is needed I was planning to keep them longer in the fridge but the question is 'Is it safe to eat them?'

Let's Get A Grip...
by: Sassy

Hi Everyone!

Okay, this page has gotten a little out of hand, so let's get a grip on things so we're all on the same page:

1. YES your beans are safe to eat if they have split upon soaking.

2. When beans split upon soaking, it's not a bad thing; meaning, they will not hurt you! The only challenge with beans splitting when soaking is when looks matter (such as for a bean salad) and you don't necessarily want split kidney beans.

3. The main challenge from the original poster was that the kidney beans split after just 2 hours of soaking. The question then became WHY did they split so quickly? This was the main point of the original post.

Personally, we have soaked kidney beans for 8 hours and they have NOT split. So what's the challenge?

Is it perhaps because they were soaked in baking soda. The jury is still out on that one. Personally, I don't use baking soda for soaking and don't see the need. But this comment will likely cause people to make a comment that their family has been soaking their beans in baking soda for generations and their beans have turned out perfect every time, etc. etc. etc.

So please, just do whatever makes you happy. :)

I think the poster from Australia gave a great answer saying: "When the outer seed coat (testa) is very dry it does not swell as readily as the bean inside, so as the inside of the bean absorbs water, the testa splits off."

So if your beans are splitting after just a couple hours of soak, it seems to me that it's because your dry beans are likely old. Check your source and buy fresher dry beans.

I do have to disagree with the poster from Australia on the point where they recommend to soak your splitting beans for a shorter amount of time. Your beans still need to soak (split or not) for the proper amount of time to help with digestibility and for great nutrient availability.

You can still use up the older ones you have, soak them for the correct amount of time (6-8 hours), but if the splitting bothers you don't use them in a dish where the visual outcome is important to you.

Hope this helps to clear things up. :)

Splitbeans
by: Allyson

Thanks so much for the last comment, totally cleared it up!

I just soaked kidney beans for the first time and they all split open. At least I can still use them, they are going to be mashed up with sasa for bean borritos.

They are probably too old. I will try a different store next time.
