Sourdough Bread And Fermenting Yeast


Jestgar

Recommended Posts

Jestgar Rising Star

Sourdough fermentation is a traditional process that retains its importance in wheat baking because it improves bread quality by prolonging shelf life, increasing loaf volume, delaying staling, as well as by improving bread flavour and nutritional properties (Thiele et al., 2004). Fermentation of wheat and rye flours with selected sourdough lactic acid bacteria following an ancient protocol which includes long-time fermentation may at the moment decrease the risk of gluten contamination in gluten-free products. Although for celiac disease patients the goal is not to decrease the gluten toxicity but to eliminate it, the authors’ laboratory is currently using a more complex microbial pool with the addition of fungal proteases which decreases the level of persistent gluten below 20 ppm and is optimizing the baking quality of the bread to get superior nutritional, sensory and rheological characteristics with respect to the current gluten-free products.

Interesting. From Italy, of course. The land of everything yummy. :D

I loved sourdough, I jumped for joy when Whole Foods announced their gluten-free sourdough. (Still haven't seen it locally.)

I started making my own sourdough breads when I was very suspcious about gluten bothering me. I always had batches of starter bubbling away all over the kitchen, and made everything, from breads to cakes and pancakes with sourdough.

Sorry to say, it still made me sick. I'd read the lactobacillus was supposed to disable the gluten, but it didn't help me. I'd read that sprouting wheat also uses up the gluten as energy for the sprouts. I had wheat sprouting in the kitchen, ground up the berries after they'd sprouted, and made them into flatbreads and cookies. These were my last ditch efforts before going gluten free...I was sicker than a dog.

Sorry...maybe it would work for others or by some other process or something, but it sure didn't help me when I made those things.

I developed a quick starterless sprouted sourdough rye bread that was incredibly tasty. I soaked the rye grains, drained off the liquid and allowed the soluble starches to ferment (natural yeast) while I sprouted the grains. I then put the grains through the blender with the liquid, added enough whole wheat flour to make it workable, added salt, and that was it. Maybe one of you has a friend or relative who is into sourdough and can make use of the technique.

I sure wouldn't eat it.

Seriously, what is "sour" about sourdough is the fact that the bacteria and yeast are fermenting the soluble starches into alcohol, carbon dioxide, and lactic acid. It will have very little effect on the gluten in a grain. Proteins don't ferment, they break down into ammonia and other noxious things.

At this point, I feel so much better that I can't even stand the thought of sourdoughing wheat/rye, etc. anymore. It just reminds me of feeling terrible.

But I am wondering about teff. We used to eat in an Ethiopian restaurant (now gone out of business) and the food was absolutely excellent stuff...they make a bread with teff flour, called injera. They allow teff flour and water to ferment for ???? hrs., until bubbly, and then make a flatbread with it that's incredibly thin and flexible. The first time we went to this restaurant, they brought out the food laying in little places on a big tray lined with this injera bread...I thought that bread was a big napkin...LOL. The lady showed us that instead of using forks & knives in Ethiopian cuisine, you just tear off a piece of the injera bread, wrap it around whichever very nicely spiced veggie (or meat, if you eat meat--Ethiopian isn't necessarily limited to veggies) and put it into your mouth by hand. The bread is pleasantly sour-tasting, and goes really well with the spicy foods.

I wanna try to ferment some teff and see how I do with injera. I tried it once several years ago and it was a total disaster...maybe it's time to try again now!

I love injera bread.

If you get this to work will you post the process?

If I ever figure out the secret to making this stuff, I'll be happy to post!

Today I bought Ivory Teff tortillas(big ones)made by Open Original Shared Link

I also am buying some Italian wheat after reading an article in Whole Living about sourdough.

I love injera bread.

If you get this to work will you post the process?

This is the best recipe I have found to date: Open Original Shared Link

It is a step by step set of instructions on the starter AND the recipe for making the bread - you may have to check out her links to get it all, as she has a few posts. This gal is a westerner who lived in Ethiopia for a while and got lots of advice and practice from other Ethiopian women, but was ignorant like us to begin with.

She does hers with wheat as well, but I followed the instructions using just injera and it turned out amazing. :-)

maybe it would work for others or by some other process or something, but it sure didn't help me when I made those things.

There has been speculation for a while in the Celiac testing community that tests for gluten levels may not detect gluten as accurately when gluten is broken into smaller pieces, which happens during hydrolyzation and fermentation (like the sourdough).

A new test was developed recently that detects fragments of protein more accurately than before, and it was used to judge how well previous gluten tests actually did in testing for gluten in fermented and hydrolyzed wheat products. Turns out, previous tests WERE underestimating the gluten in these products, sometimes by almost half.

So that puts into doubt any test results from fermented wheat products, like the sourdough. Fermentation may lower gluten, but we don't have good tests yet to tell us by how much, except for our own bodies. :-/

      @tiffanygosci, Hello.  I apologize for your thread being hijacked.   I recognize your symptoms as being similar to what I experienced, the migraines, food and chemical sensitivities, hives, nausea, the numbness and tingling, joint pain, tummy problems, sleep problems, emotional lability, and the mom brain.  My cycle returned early after I had my son, and I became pregnant again with all my symptoms worsening.  Unfortunately, I lost that baby.  In hindsight, I recognized that I was suffering so much from Thiamine deficiency and other nutritional deficiencies that I was not able to carry it.   Celiac Disease affects the absorption of nutrients from our food.  There's eight B vitamins that must be replenished every day.  Thiamine Vitamin B1 becomes depleted first because it cannot be stored very long, less than two weeks.  Other B vitamins can be stored for two months or so.  But Thiamine can get low enough to produce symptoms in as little as three days.  As the thiamine level gets lower, symptoms worsen.  Early symptoms like fatigue and anxiety are often attributed to life situations, and so frequently go unrecognized by medical professionals who "have a pill for that".   I used to get severe migraines and vomiting after gluten consumption.  Thiamine and the other B vitamins are needed to turn carbohydrates, fats and proteins into fuel for our bodies.  With a large influx of carbohydrates from gluten containing foods, the demand for Thiamine increases greatly.  Available thiamine can be depleted quickly, resulting in suddenly worsening symptoms.  Emotional stress or trauma, physical activity (athletes and laborers) and physiological stresses like pregnancy or injury (even surgery or infection) increase the need for Thiamine and can precipitate a thiamine insufficiency. Pregnancy requires more thiamine, not just for the mother, but for the child as well.  The mother's Thiamine stores are often depleted trying to meet the higher demand of a growing fetus.  Thiamine insufficiency can affect babies in utero and after birth (autism, ADHD).  Having babies close together doesn't allow time for the mother to replenish thiamine stores sufficiently.   Thiamine insufficiency can cause migraines, pins and needles (paresthesia), and gastrointestinal Beriberi (gas, bloating, diarrhea or constipation, back pain).   Thiamine deficiency can cause blurry vision, difficulty focusing, and affect the eyes in other ways.  Thiamine deficiency can damage the optic nerves.  I have permanent vision problems.  High histamine levels can make your brain feel like it's on fire or swelling inside your cranium.  High histamine levels can affect behavior and mood.  Histamine is released by Mast Cells as part of the immune system response to gluten.  Mast Cells need Thiamine to regulate histamine release.  Mast Cells without sufficient thiamine release histamine at the slightest provocation.  This shows up as sensitivities to foods, smelly chemicals, plants, and dust mites.  Thiamine and the other B vitamins are needed to lower histamine levels.  Vitamin D is needed to calm the immune system and to regulate our hormones.  Menstrual irregularities can be caused by low Vitamin D.   Celiac Disease is a disease if Malabsorption of Nutrients.  We must take great care to eat a nutritionally dense diet.  Our bodies cannot make vitamins.  We must get them from what we eat.  Supplementation with essential vitamins and minerals is warranted while we are healing and to ensure we don't become deficient over time.  Our bodies will not function properly without essential vitamins and minerals.  Doctors have swept their importance under the rug in favor of a pill that covers the symptoms but doesn't resolve the underlying issue of malnutrition. Do talk to your doctor and dietician about checking for nutritional deficiencies.  Most blood tests for the eight B vitamins do not reflect how much is available or stored inside cells.  Blood tests reflect how much is circulating in the blood stream, the transportation system.  Blood levels can be "normal" while a deficiency exists inside cells where the vitamins are actually used.  The best way to see if you're low in B vitamins is to take a B Complex, and additional Thiamine and look for improvement.   Most vitamin supplements contain Thiamine Mononitrate, which is not easily absorbed nor utilized by the body.  Only thirty percent of thiamine mononitrate listed on the label is absorbed, less is actually utilized.  This is because thiamine mononitrate is shelf stable, it won't breakdown sitting on a shelf in the grocery store.  It's so hard to breakdown, our bodies don't absorb it and can't turn it into a form the body can use.  Take Thiamine in the form Benfotiamine or TTFD (tetrahydrofurfuryl disulfide) which the body can utilize much better.  (Ask for an Erythrocyte Transketolace Activity test for Thiamine level.  Though not accurate, this test does better picking up on a thiamine deficiency than a blood test.) Are you keeping your babies on a gluten free diet?  This can prevent genetically susceptible children from developing Celiac Disease.

      @Riley, on this forum we sometimes get reports from people with similar experiences as you. That is, their celiac disease seems to go into remission. Typically, that doesn't last. At age 18 you are at your physical-biological peek in life where your body is stronger than it will ever be and it is able to fight well against many threats and abuses. As Wheatwacked pointed out, absence of symptoms is not always a reliable indicator that no damage is being done to the body. I was one of those "silent" celiacs with no symptoms, or at least very minor symptoms, whose body was being slowly damaged for many years before the damage became pronounced enough to warrant investigation, leading to a diagnosis. By that time I had suffered significant bone demineralization and now I suffer with back and neck problems. Please, if you choose to continue consuming gluten, which I do not recommend, at least get tested regularly so that you won't get caught in the silent celiac trap down the road like I did. You really do not outgrow celiac disease. It is baked into the genes. Once the genes get triggered, as far as we know, they are turned on for good. Social rejection is something most celiacs struggle with. Being compliant with the gluten free diet places restrictions on what we can eat and where we can eat. Our friends usually try to work with us at first but then it gets to be a drag and we begin to get left out. We often lose some friends in the process but we also find out who really are our true friends. I think the hardest hits come at those times when friends spontaneously say, "Hey, let's go get some burgers and fries" and you know you can't safely do that. One way to cope in these situations is to have some ready made gluten-free meals packed in the fridge that you can take with you on the spot and still join them but eat safely. Most "real" friends will get used to this and so will you. Perhaps this little video will be helpful to you.

      @Riley., Welcome to the forum.   It was once believed that Celiac Disease was only a childhood disease and it can be outgrown.  That was before 1951, before gluten was discovered to be cause of Celiac Disease, also called Infantilism.  Back then Cileac Disease was thought to be only a gastro intestinal disease, once you  "outgrew" the colicky phase, you were cured. You were so lucky to be diagnosed at 5 years old so your developing years were normal.  Gluten can affect multiple systems.  The nervous system, your intellegence. The muscules, skeleton. It can cause neurological issues like brain fog, anxiety, and peripheral neuropathy.  It can cause joint pain, muscle weakness, and skin rashes. Epilepsy is 1.8 times more prevalent in patients with celiac disease, compared to the general population. Because through malabsorption and food avoidances, it causes vitamin D and numerouus other essential nutrient deficiencies, it allows allergies, infections, poor growth, stuffy sinuses and eustacian tubes. There is even a catagory of celiac disease called "Silent Celiac".  Any symptoms are explained away as this, that or the other thing. Gluten is one of the most addictive substances we consume.  Activating the Opiod receptors in our cells, it can numb us to the damage that it, and other foods are causing.  It has become socially acceptable to eat foods that make us feel sick.  "There's a pill for that".   It is generally accepted that n fact you are weird if you don't. The hardest part is that if you don't eat gluten you will feel great and think why not.  But slowly it will effect you, you'll be diagnosed with real diseases that you don't have. You'll be more susseptable to other autoimmune diseases.  As you read through the posts here, notice how many are finally dianosed, after years of suffering at older ages.  Is it worth it? I think not. Perhaps this book will help:  Here is a list of possible symptoms:

      Hi! Im Riley, 18 years old and have been diagnosed for 13 years.. the testing started bc I stopped growing and didn’t gain any weight and was really small and thin for my age.  I got diagnosed when I was 5 and have been living gluten free since, in elementary and middle school it was hard for me and I kept contaminating myself bc I wanted to fit in with my friends so so badly. I ate gluten secretly at school and mostly regretted it 30 minutes later.  I’ve had symptoms like diarrhea, nausea, headaches, stomachaches, threw up a lot and was really emotional.  In 2022 I really started working on myself and tried to stay gluten free and if I did eat gluten I wouldn’t tell anyone and suffer in silence.  Last year in July I begged my mom to let me „cheat“ one day bc I just wanted to fit in… I ate a lot of different stuff, all the stuff I missed out on in my childhood like nuggets, pizza and all that.. I didn’t have symptoms that day and was doing really fine My mom and I wanted to test how far we can go and said we would test it for 12 weeks to get my blood taken after to see if I’m doing good or if symptoms start showing  As a now 18 year old girl who finally gained a normal weight and doesn’t get symptoms I’m to scared to get tested/my blood taken cuz I finally found comfort in food and it got so much easier for me and my family.  A year and 4 months later i still didn’t get any symptoms and have been eating gluten daily.  I’m scared to get tested/my blood taken cuz what if I’m actually not fine and have to go back to eating gluten free. Any tips to get over that fear and „suck it up“ cuz I know I could seriously damage my body… sorry if I seem like a idiot here… just don’t really know what to do :,)

      There is much helpful 'truth' posted on this forum. Truths about Celiac Disease are based on scientific research and people's experience. Celiac disease is inherited. There are 2 main Celiac 'genes' but they are variations of one gene called HLa - DQ What is inherited when a person inherits one or both of the DQ2 or the DQ8 is a predisposition to develop celiac disease after exposure to a environmental trigger. These 2 versions of the DQ gene are useful in diagnosing  celiac disease but there are about 25 other genes that are known to influence celiac disease so this food intolerance is a multigenic autoimmune disease. So with so many genes involved and each person inheriting a different array of these other genes one person's symptoms may be different than another's symptoms.  so many of these other genes.  I don't think that much research on these other genes as yet. So first I wrote something that seem to tie together celiac disease and migraines.  Then you posted that you had migraines and since you went gluten free they only come back when you are glutened. Then Scott showed an article that reported no connection between migraines and celiac disease, Then Trents wrote that it was possible that celiacs had more migraines  and some believed there was a causal effect. You are each telling the truth as you know it or experienced it.
