Does Distillation Remove All Gluten?

Frederik Willem Janssen is head of the Chemistry Department, Food Inspection Service in Zutphen, and a subsidiary of the Inspector of Health Protection (similar to the FDA in America). Their lab has a special interest in.... modified gluten, edible packaging materials (which may contain gluten), and detection of hidden gluten in foods, including the development of improved detection methods. He is also a member of the Medical/Scientific Advisory Committee of the Dutch Celiac Society.

Distillation quite effectively removes the gluten and it is very unlikely that splashes of fermented (we call it "moutwijn", i.e. malt wine, can’t remember the correct English word for it) will be carried over to the final distillate. If they are present they must have been added afterwards. A couple of years ago we analyzed some distilled liquor for presence of gluten proteins but we couldn’t detect any in this set (about 40 different types). The beer test, which consisted of a set of 50 different brands, showed that most brands (35) did contain immunoreactive protein in amounts between 1 and 200 mg/liter. Only 15 contained less than 1 mg/liter. There was a strong correlation between the gluten content and whether wheat had been used as an ingredient!

I found a report in a periodical by the Flemish Celiac Society of an investigation that was published in 1992 about immunological determination of gluten in beer and some distilled liquor. This confirmed our findings that the gluten content of beer is quite variable (the authors found levels from zero to 400 mg /liter gluten).

They did find gluten in distilled liquor! The levels varied from zero to 200-mg gluten/liter. The highest amount was found in a "Creme de Framboise" (200 mg/liter) but second was a French brandy VSOP with a score of 180 m g/liter. A Dutch gin was negative, which might be an indication that gluten in these type of liquor is not a carry over to the distillate! My guess is that this gluten is derived from the caramel coloring, though there is no proof about this yet. I always advise sensitive patients to abstain from brown colored liquor!

I would like to stress that the determination of gluten in these types of products is very unreliable and we have to count with false positive as well as false negative values. The gluten proteins could have been broken down to small (but still toxic) peptides and in that case a sandwich-type ELISA might produce false negative results because in that case you always need to two epitopes (binding sites for the antiserum) on one molecule to get a positive reaction. A competitive type assay would be the choice for this type of product, but we haven’t tried this type of analysis yet. We did use it on a soy sauce, which was prepared with wheat gluten and didn’t find any gliadin, which might be an indication that gluten had been broken down to very small peptides with less than one binding site.

Best wishes,
Frederik Willem Janssen, Zutpen, The Netherlands.

This still leaves me wondering if the grain alcohol in Pam Spray or any other product such as Vanilla, Allmond extracts contain gluten.
Can you Help!!!!! Thank you Pam

I do not risk consuming anything that was once wheat or still is. I have drank many types of alcohol and have had the same painful wheat symptoms. My grandmother said to me once, "You do not need alcohol to have a good time!"

There is zero doubt in my mind that cheap alcohol distilled from grain still contains some amount of gluten. I get terrible and immediate reactions.

That's good to know about Texas Children's, unfortunately I don't believe they accept our insurance. Our former pediatrician joined with one of their medical groups and we had to find a new one due to insurance. I'll check out their site though.

Texas children's hospital in the med center has a celiac center now. https://www.texaschildrens.org/departments/celiac-disease-clinic Good luck!

this is a very common subject on here. personally, most of my tests were negative, but i did the same thing you did (stopped eating gluten before the tests) my gi advised me to continue eating gluten free because i was so malnourished and when i stopped the gluten i actually began to gain weight. in other words, i think she was afraid for me to do the challenge bc it might kill me lolz. some people want a definite dx if they have kids that need to be tested in the future, some will not follow a strict g//f diet without a firm diagnosis (they think they can cheat just bc they were never formally diagnosed) what happened with my scope is the dr saw evidence of damage. that and my response to the diet were enough for me. she advised me to stay gluten-free and i agreed. it's been tough sometimes, but i never purposely cheated (that's how near death i was - swore i was dying of the big 'c'.......what a relief to not have that and my 'chemo' is 'impasta'. or fake bread. ) welcome to the forum and good luck with whatever you choose

I'm already noticing a difference after five days on the gluten-free diet...acid reflux is gone and stomach pain is getting better. I am glad you're going to try the gluten-free diet, Vanillabean, and get copies of all your results. I hope you find some relief from the pain soon! I'm still waiting for my biopsy results. I did call my doctor's office today and found out the genetic test was positive for a celiac gene (DQ8). My doctor was hoping to rule out celiac with that test, but now it's still up in the air. Still waiting.

meeeeeee!!!! i used to get pneumonia every single winter!!!! and all the flus and colds, etc - i am surrounded by kids and germs, but when they all get the flu, i do not. my husband (mr-play-through-the-pain) even got knocked down (spent 2-3 days in BED miserable) by the last round of virus, but not me. not to mention no headaches, no migraines, etc. hormones and the dreaded menopause, like hellodee2 said, is a whole 'nother ballgame lolz glad you are feeling better
