Can Gluten Molecules Permeate Egg Shells?
0

11 posts in this topic

I'm doing some research and have a question.

If someone hard boil eggs in a pan that may contain traces of gluten, e.g., boiled pasta previously, could that cross contamination be absorbed into the inside of the shell to the egg? I would certainly expect cross contamination to be possible on the shell, but I'm wondering if anyone knows whether the egg shell is porous enough to allow the gluten into the uncracked egg itself?

I don't THINK so, but when you crack the shell, any CC on the outside is bound to touch the inside, even if just for a second.

If this were possible I'm pretty sure there would be warnings about it somewhere. On top of the shell of the egg, don't forget that there is also the skin inside between the shell and the part we eat. If you are truly that paranoid you can shell them under running water which is tbh about 100 times easier than shelling them any other way.

Edit: I realized after I posted that this may come off wrong, don't take it the wrong way. I am the most paranoid person I know since going gluten free. Seriously. I'm more afraid of gluteny children than contagious illnesses. Boiled eggs don't scare me in the least.

Thanks so much! I'm actually asking less for culinary purposes and more for research for something I'm writing. But I guess it would be a good thing to keep in mind if you're traveling.

And, no - please don't worry about offending me. I have a pretty "hard shell" - OK, my feeble attempt at humor. :D

I'd be interested to know how one could accurately test it, since a needle must go through the shell...you get my point.

I'd think the point is that it would get contaminated by touching the outside of the shell...unless you wash with soap???

Then you'd need to test the shell....

How bout just don't boil it in gluteny or cc water?

I bet you could find something on the permeability of eggs and then the size of gluten molecules. Are the molecules too big??

Oh look, this is how you could test it! http://www.stevespanglerscience.com/experiment/naked-egg-experiment

Yes, you are absolutely correct! The size of gluten molecules must play a big part in this, but I wonder if the gluten molecules could possibly be carried through by osmosis even if the water molecules could not??? Clearly, I'm no scientist!

But thanks for that link. It got me thinking that perhaps I could do a test with food coloring in the water and hard boil the egg. If no coloring comes through in an uncracked egg, then perhaps nothing else go through? Hmmmm. Like I said, I don't want to eat it. I'm writing a novel and I'm kicking around a possible metaphor.

Thanks so much for letting me pick your brains!

If the pan was washed well I wouldn't worry about it.

If the shell was cracked IMHO it might be more of a concern.

Your idea to boil some eggs in water with food coloring as an experiment sounds good to me. Let us know the outcome if you do it.

Egg shells are highly permeable.

In my opinion, it depends on how sensitive you are; or how are aware of your symptoms you are, that you may react. Have you had issues?

Agreed. Water can certainly get through them, but water (H2O) is a small molecule, with an atomic mass of 10. Prolamine molecules (gluten) have atomic masses in excess of 1,000. They are long chains of amino acids--which are themselves large.

Thanks for the input and so sweet of you to ask, but I'm OK. My question is purely research. But it has made me wonder about eating boiled eggs from a pan of questionable cc status.

    • Good grief!  :o. I'm so sorry, I wish there was something I could do or say to help you.  I agree with the NP, your primary needs to be requesting copies of your records from the other doctors, as well as the records and lab reports from your hospital stay.  They are supposed to work together as a team, not just individually out in left field.
    • Just a quick one to say I got a diagnosis of celiac disease today. I know in the past it's been helpful for me to know the outcome for other folk, so thought I would update. The moral of this story is even with a VERY borderline blood test it's worth persisting. thanks for all the help Sue

    • Well, I am stressed to the max. I just spent 3 days in the hospital with D and stomach pain, dizziness, chest pain, generally unwell. Then another trip to the ER on top of that. My protein was low and my RBC and hemoglobin dropped below normal in 3 days. Not terribly low, but below normal. I also had metabolic acidosis which still confuses me. I usually eat every 2-3 hours despite it causing pain to keep my energy up and was unable to eat that frequently in the hospital. I usually carry protein with me and had been taking liquid iron which I stopped a few weeks ago because my new endo is not a fan of iron supplements. As soon as I got home from the hospital I started with my protein drinks and blackstrap molasses for iron.  I now have bilateral mild pleural effusions and a nodule on my left lung, which hopefully is nothing, but was not there on a CT back in March. In addition, my left adrenal gland, which also appeared normal in March, is calcified and the report indicates this is most likely due to a previous bleed or infection. My colon appears tortuous (whatever that means) and we are waiting on colon/endo biopsies. I have been gluten-free since March except for cc so expect the biopsies to again be negative.  My primary care is useless. I am in the process of getting a new one I will see on the 7th but need the current one to fill out FMLA paperwork because I both physically and mentally need time to recover. I will have to go off of payroll for 2 weeks but I think I need to. I called the primary's office today to discuss the hospital tests which she does NOT have yet and to ask if we should/could start a low dose of prednisone because my body is attacking itself. My thyroid on ultrasound is also abnormal though my bloodwork thus far is normal. But it hurts on that side. The only reason the ultrasound was ordered is because I asked for it in the first place. The only reason I have started seeing an endocrinologist is because I found one myself. Anyway...I broke down in tears on the phone eith her today and she told me I was having a "manic episode". I have no history of mania. I only recently started taking xanax to help me cope with the stress of being sick. I was not sick until I did this stupid gluten challenge over the winter. My mother was in town and spoke with the doctor on the phone as well who was trying to get my mom to take me to a psych hospital. She also threatened to send the police to check on me. My mother assured her I was in no danger and we hung up the phone in complete shock. Admittedly, I was in tears when I called her and probably sounded like a fucking mess. But I believe I referenced the dropping iron, protein, fluid near lungs, enlarged thyroid and attacked adrenal gland then literally said "my body is attacking itself and I need help" to which she said, "I think you are manic". Lovely. If I was a mess before that phone call it was 10x worse when we hung up.  Anyway, this is the first night it has been extremely difficult to sleep. I admit my thoughts about my odd symptoms keep me up often recently. I mean, who the hell bleeds from or gets an infected adrenal gland?! I am sure it was another time I begged my primary for help. On a side not, the NP at the ER told me the primary should be putting these pieces together and communicating with my other doctors better. He then stated that he used to go to the same practice but left because the practice got too big and like a business. So I got some validation from that chat.  A melatonin or a .25 xanax usually does the trick for me to sleep but I am so disturbed about my interaction today, stressed at my health, stressed that my ex has our son so much because I am always sick (bless him for coming through), stressed that I have to go back to this awful doctor because I will need the FMLA paperwork before I see the new doc on the 7th.  8 months ago, I took a multivitamin when I remembered it and that was it.  End rant. Maybe now that it is off my chest I can finally sleep.
