cintinative Posted May 25, 2021 Posted May 25, 2021 (edited) aka Microbial transglutaminase Apparently a recent (ETA: February 2020) study found that a person with Celiac could react to the meat glue in the same way they would the autoantigen transglutaminase. Here's the study: https://www.mdpi.com/1422-0067/21/3/1127 Here's an article: https://www.celiac.com/articles.html/should-celiacs-worry-about-microbial-transglutaminase-aka-meat-glue-r5535/ It sounds like they are not required to label for this. In another article, they recommend you talk to your butcher about what meats to avoid that might contain this meat glue but I'll be honest--I buy my meat at a supermarket and rarely interact with the butcher. Insert from study: It is considered as a food/meat glue and used routinely in meat, fish, seafood, surimi, milk and dairy, sweet foods, and bakery products [8,9,10,11]. mTG improves dough stability, elasticity, persistency, volume, hydration, elongates shelf life, and provides better fermentation tolerance in baked goods such as bread, pastries, pasta, and tortillas. The enzyme is also used in gluten-free products to improve their texture and qualities, as announced by manufacturers. As a result, Western societies ingest mTG in substantial quantities [6,12]. What do you all know about this? We don't buy imitation crab, which is apparently one of the offending foods. This is just so weird. Edited May 25, 2021 by cintinative 1 Quote
Danae Posted May 25, 2021 Posted May 25, 2021 Oh, that’s a major bummer. Meat glue is amazing. It’s in chopped and molded meat products, but also sometimes in fancier meats. Here’s a video from a local high-end restaurant about how they cut the cap off the prime rib, take the tough membranes out, and glue it back together. Quote
ktgrok Posted May 25, 2021 Posted May 25, 2021 Well, crap. Is this going to be in say, chicken nuggets? We buy gluten free ones, but I guess this wouldn't be included in that. UGH!!! Quote
kbutton Posted May 25, 2021 Posted May 25, 2021 I wonder if doing bloodwork would pick up trace amounts if you're concerned it's being consumed without knowing about it. Quote

Faith-manor Posted May 25, 2021 Posted May 25, 2021 I don't know.about this. But watch out for "grilled food" at fast food places. I got a grilled, supposedly GF, chicken breast at a deli, and head a reaction. Googled it. Turns out that many places don't grill it put paint grill marks on it with food paint so it looks grilled and food paint is made with wheat. I had what they said was GF barbecue sauce - and in truth, I have never had trouble with BBq sauce before - on it, kind of smothered a bit so I could not see the fake grill marks. So if I eat out, pre-pandemic, I only did sit down at places I could trust which aren't many. I am not a celiac sufferer but am allergic and digestively intolerant. I have become a bit fan of picnics. 1 Quote

Well, each year we run a TTG test on his blood to check on his Celiac. The lower the number, the better. If this is a reason that his number isn't lower than it is, then I would like to know what products contain this additive, if that makes sense. It's not the same as testing for this additive specifically. 1 Quote

The bun comes still in the package, they con't cook anything but fries in the fry oil, and seem very careful. Except, last time they gave us the friend (battered with wheat flour) chicken instead of the grilled gluten free on...but with a gluten free bun, lol. My mistake probably, when ordering. 5 minutes ago, cintinative said: That's what I am not sure about. We buy GF chicken nuggets from Costco.

I just filled out the contact form on the Tyson website to ask if their gluten free nuggets have it. You might want to find the manufacturer website and contact them. 1 Quote

Short of make EVERYTHING from scratch? I don't WANNA make my own nuggets and ice cream and cookies and french fries!!!! And yes, I know that is whining and premade food is a luxury, but this is my kid that had total food refusal other than like, 1 food, due to PANDAS who is finally sort of eating more variety. I NEED those chicken nuggets. I gues, on the one hand, since he has so few things he really likes, it will be easier to contact companies to ask about it...Sigh. If this crap is in Luna Bars we are sunk. He survives off those. I just need those, tyson gluten free chicken nuggets (not the strips, those are different and he won't eat them), and banquet maple sausages to be without it, lol. He can live off those and fruit.

This is what the article says, "Microbial transglutaminase, also known as ‘meat glue,’ is an enzyme commonly used in the meat industry to “glue” together smaller pieces of fish or meat to make a single larger piece from numerous smaller chunks.

Indigo Blue Posted May 25, 2021 Posted May 25, 2021 Ugh. Makes me want to cook and eat only at home. (Which, honestly I pretty much do because food just keeps getting grosser and grosser). I wonder if non-dairy ice cream has this? Maybe this would be an option for some if this is true? 1 Quote

Jean in Newcastle Posted May 25, 2021 Posted May 25, 2021 Items that are certified gluten free still have to meet the “no less than X parts per million “ test. I personally would still trust anything certified gluten free. But some might be more sensitive. Our ttg tests have always been low with staying certified gluten free.. 1 Quote

Basically my understanding is that normally our own body produces transglutaminase when we eat gluten, and that transglutaminase is then what can trigger the autoimmune reaction. So if the gluten free food has this enzyme in it you still get a raction. Quote

From the study, but I will admit that more than 80% of it is unintelligible to me: The thing I am not clear on is that I read online about the mTG being associated with wheat, and that in those cases the manufacturer has to report it. So I am not sure what it means that this can be found in GF products. I just don't understand enough of the science. Quote

cintinative Posted May 27, 2021 Author Posted May 27, 2021 This was our gastro's response to my question about how worried we should be. It is an interesting theoretical hypothesis but to date there is not significant clinical data to suggest he needs to worry about it. As is stated in the study mTG is ubiquitous and also likely produced but the normal gut flora. It will be interesting to follow these studies to see if additional clinical data arises Please let him know for now, it should not restrict his food choices further and we will continue to follow him clinically and with routine labs including tTG. 3 Quote
