Lacto Fermented Rice Tutorial

After watching the popularity of “Safe Starches” blossom in the Paleo community over the past few months, I decided some experimentation was in order. Potatoes and white rice are cheap foods, and who couldn’t use a little help with their budget nowadays? Past forays into the world of starch did not go well for me. Potatoes, rice and corn don’t seem to play well with my stomach.

I did, however, become hopeful again when I started learning how to ferment foods. I can’t say that I’m brand new to fermented foods, as I’ve been fed fermented sauerkraut for as long as I can remember, and I always remember having fermented pickles in the house. However, the fermented foods I ate were always store bought, never fermented at home… and anyone who has ever purchased fermented foods in the store knows how pricey they can be! But more than that, the fermented foods you typically find in a store (cabbage, carrots, yogurt, etc) were not the foods I was looking for. When is the last time you saw lacto fermented rice in the grocery store?

But I knew our friendly little lactobacilli friends (read: the friendly bacteria found in yogurt and probiotics) will eat the heck out of starch and sugar. So, my plan went, they should make rice easier for me to digest, possibly allowing me to eat rice without pain and therefore lowering my grocery bill. It was all such a cunning plan!

It did, in fact, make the rice easier to digest. (Both brown and white rice.) So if your intestines are in good working order, this may be a good plan for rice. However if you have trouble digesting starch, I’d probably still stay away from it.

But, if you do eat rice on any regular basis, fermenting does seem to be a good way to break down foods and make nutrients more available to your body. It also increases the amount of certain nutrients contained in these foods – many of which seem to be in the B vitamin family:

“About 100gm of cooked rice has only 3.4mg of iron, while for the same quantity of rice fermented for 12 hours, the iron content went up to 73.91mg. Likewise, sodium, which was 475mg came down to 303mg, potassium went up to 839mg and calcium went up from 21mg per 100gm of cooked rice to 850mg, after 12 hours of fermentation of the same quantity of rice,” Barooah said.

That’s definitely a bonus! So, if you are interested in trying this experiment for yourself, here’s how I did it.

Lacto-Fermented Rice Tutorial
(Printer friendly recipe below)


1 cup dry rice (brown or white)
1 1/2 cups water (filtered is probably best)
2 tablespoons whey (Instructions for how to collect whey)

Step 1: Add rice, water and whey to a jar – I used this jar from Bormioli Rocco. Make sure the jar is large enough so you have a few inches of room at the top. Cover the jar and leave in a warm spot in your house. I usually leave mine on the counter top next to my refrigerator so the jar catches the warmth coming off the back of the fridge. Let sit for 12-24 hours.

Step 2: After 12-24 hours, cook the rice as follows: (Note: Use these cooking directions to make plain rice. If your recipe gives you other cooking directions, use those.) Dump the contents of the jar (water and all) into a pot with a lid.

Step 3: Cover and bring to a boil.

Step 4: Once it begins to boil, turn down to low and leave covered until the rice has soaked up all of the water – maybe about 30-45 minutes. Fermented rice does seem to take a little longer to cook than un-fermented rice.

Step 5: Serve by itself, topped with a little butter, or with another recipe – like Golabki (stuffed cabbage)Coconut Curry, or Sweet and Sour Pork.

    How come it takes longer to cook if the starch content has been reduced? My only guess is due to using the brine from the rice. Maybe the acidic brine prolongs the cooking time.

    • Domestic Soul

      Possible. But also, by reducing the starch, you’re also changing the structure of the rice, so that could also be the cause. I can’t really tell you for sure.

      • Martin

        How do you know that in fact it made the rice easier to digest when soaking with whey?

        I’ve read that they leave it overnight with water after boiling the rice.

  2. Sara

    Curious, does the rice have a sour flavor?

    • Domestic Soul

      I’ve never noticed a sour flavor after fermenting it. If I had to make a guess, I’d say that it would have to ferment a lot longer than 12 or 24 hours to get the sour flavor. (In my head, I’m comparing it to sauerkraut, which gets more sour the longer you leave it – usually over months.) This short fermentation seems to be just long enough to break it down a bit without altering it too much.

    Do you think I could use a vegetable starter culture powder for this instead of whey?

    • Domestic Soul

      I can’t guarantee results, because I haven’t tried it myself, but I don’t see why a vegetable starter culture wouldn’t work. I think it should be ok.

    • Tiff

      Was wondering if you tried the vegetable starter? I am really missing rice, but don’t want to use whey. If veggie starter worked for you, thought I’d try it!

    Do you know if this would work with quinoa?

    Can apple cider vinegar be used instead of whey?

    And can other rice be fermented such as wild rice and Haiga-mai (germ rice)?


    • Domestic Soul

      Hey Ally,

      I do know you can use other rices. I haven’t tried wild rice yet, but I have tried jasmine, basmati, long grain white, and so on. I bought some forbidden rice to try this on as well.. So I’m excited to try that out.

      I can’t tell you if ACV would work, as I have never tried it and haven’t heard of anyone trying it. But I’ll keep an eye out for more info on it and let you know if I see anything.

    Do you know where I can find nutritional information on lacto-fermented rice? I’m curious about how much of the starch is eaten by the lactobacilli. I’m a pregnant,T2 diabetic trying to stay out of ketosis, while still controlling my glucose without injecting too much insulin.

    • Domestic Soul

      I haven’t seen anything on the amount of starch left. Most of the nutritional information listed for fermented rice is about the increase in available nutrients. Like this statement (
      from this article):

      “About 100gm of cooked rice has only 3.4mg of iron, while for the same quantity of rice fermented for 12 hours, the iron content went up to 73.91mg. Likewise, sodium, which was 475mg came down to 303mg, potassium went up to 839mg and calcium went up from 21mg per 100gm of cooked rice to 850mg, after 12 hours of fermentation of the same quantity of rice,” Barooah said.

      Everyone seems to agree (from what I’ve read) that the starch is indeed “broken down” and leads to “increased digestibility”, but no one seems to give specific numbers. Helpful, right? I know.

      That said, it is an interesting question, so I will absolutely keep an eye out and let you know if I come across anything. I do have a number of fermentation books to get through, so who knows what I’ll come up with.

      • Terran

        Wow…the increase in iron makes any increase in insulin needed worth it! Thank you for this information.
