Celiac Disease Future: A Device that Detects Gluten in Food?

Celiac.com 10/18/2012 - Currently, there is no convenient way for people with celiac disease to test food for gluten content. In an effort to change that, University researchers in Spain are using Sunrise™ absorbance readers by Tecan, together with Magellan™ V4.0 software to create an accurate, easy to use sensor that can test for gluten in food.

Photo: CC--chrisinplymouthMaria Isabel Pividori from the Sensors and Biosensors Group at the Universitat Autònoma de Barcelona confirmed the development of the "electrochemical magneto immunosensor for the sensitive detection of gliadin – and small gliadin fragments – in natural or pretreated foods.” Gliadin is the main protein trigger for celiac disease.

The sensor is an important step toward addressing "increasing demand for rapid, simple and low cost techniques for accurate food analysis in decentralized analytical situations," said Pividori.

The research team measured the performance of the electrochemical immuno-sensor by comparing it with a new magneto-ELISA, using optical detection performed on the Sunrise plate reader.

The team conducted ELISAs in 96-well microplates, using a magnetic separation plate to isolate the supernatant before measuring the absorbance in the Sunrise reader.

This enabled the team to conduct immunoassays in a number of various formats for multiple applications – such as evaluating protein coupling to magnetic beads and nanoparticles – as well as allowing assessment of different transducer materials for bio-sensing purposes.

Because it offers "a quick and easy way to optimize reagents and assay parameters," Pividori calls the Sunrise "ideal for research applications."

So just how far off is a commercially viable device that will allow people with celiac disease to test gluten levels in their food? Only time will tell, but stay tuned for more developments as researchers try to deliver such a device.

Meantime, let us know what you think. Would you like a device that could easily and accurately test food for gluten? Would such a device make your gluten-free life better or easier? Comment below to let us know your thoughts.

Full details of this study can be found in: Laube T et al. Biosens Bioelectron, 2011, 27, 46-52.

The problem with this is that the food would have to be bought first, then taken home to test. If it's not gluten-free, the money has been wasted.

Actually I'm thinking of using it at a restaurant when they offer 'Gluten-Free Food" as a double-check!

I would love a gliaden sensor to test food for gluten. Because of other health issues, I can't readily tell if I have ingested gluten and my daughter is asymptomatic. A gluten detector would help keep us from eating contaminated food and lower the stress level of eating out.

It would be amazing. We would buy several to keep in different places. I would think pretty much anyone with celiac disease or gluten intolerance would buy one as long as it was affordable.

Yes... this would be a wonderful device. I've thrown away so much food that people have (with best of intentions) brought me from their kitchens or bakeries claiming to be gluten-free. From experience I've learned that I can not risk eating such items. This would probably allow me to enjoy many more options with the confidence that I won't have a reaction or compromise my health.

I have been on a strict gluten-free diet for years and I still have antibodies. Hidden gluten or cross contamination are the likely sources. I would love one of these at a manageable cost.

I have been wondering why someone can not create a swab to use when we eat out we could stick it in food. Maybe it could change colors like an acidity or urine analysis.

I would love to have it to see if Modified Food Starch on label is gluten or not. I don't use these foods but I might be able to eat them if I could test them. It would also have to be reasonably priced.

I would LOVE LOVE LOVE to have a sensor. It would make eating away from home so much less stressful. I would use it when I go to restaurants - particularly new ones where I wasn't sure they really understood what gluten was.

I would love to have one to prove to my husband how important cross contamination is. He is the cook of the house and insists that he cooked a gluten-free meal. But unless I prepare my on meals I usually get sick. It hurts his feelings when I don't want to eat his meals.

I have been saying for a while that I would pay good money for something like this - it would be worth it just to be sure of what I'm eating and to be able to try things that I regularly wouldn't take the risk with. The only problem I have is if a crumb from cross-contamination is enough to upset my body, then I would need to be able to test the entire amount of food, not just stick it in one place and assume that there's no gluten throughout.

I would like to know how sensitive this test is. If it can test below 20 ppm to very low levels of gluten I would be happy. My son gets sick from products that contain 5 ppm gluten...

I would LOVE to have a sensor and have spoken to other coeliacs who all agree. I hope it will be available VERY soon. I can feel a sense of relief already that I will be able to eat safely, especially when I am away from my home.

I'd buy one of these! I don't eat out that often, but this would be really handy to have. I'd also bring it to my in-laws, as I swear they are trying to kill me with holiday dinners. But I could see a lot of use for this - people who travel a lot, for instance, would really benefit from this device. Great idea.

Yes, if it is reasonably priced -- my gluten-free budget is a huge part of our overall budget. This device would be so terrific to have in a restaurant setting, especially, say, a Chinese place where they vigorously nod their heads when asked if items are gluten-free. Hey, they use soy in lots of ways.

I see this as a most welcome and useful tool! Yes, I would buy it without hesitation. There is way too much guesswork in the gluten-sensitive world, and this would offer some peace of mind and much needed added safety with all the products that leave you in doubt. I'm wondering if this would work on non-food products like toothpaste or lipstick. Whatever it works on, I'm for it!

All the foods that tout Gluten Free on the packaging and then the fine print says "produced in a facility that uses wheat...". I almost exclusively eat Certified Gluten-Free foods now. I would love to have a tester for these products and cross-contamination issues within my own kitchen. I would even sell these in my massage clinic. My clients are constantly asking about celiac disease.

This tool would go a long way to ease my anxiety when I choose to eat something that appears to be gluten-free - such that manufacturer labeling is not always accurate and well-meaning friends and relatives may miss a step in avoiding cross contamination.

Yes... it will be really helpful if we have a tool which can detect the possibility of gluten in the food that we eat outside our home, especially in countries like India where awareness about this health problem is not enough.

I’m a Biotech student and sorry but I’m in shock. This device is a laboratory equipment. It is based in ELISA methods: ELISA assays can take 2 hours until you can measure the results even if the results can be read in 6 secs, you need to be a lab technician to manipulate the samples and the device, for sure you must have pipettes and lab stuff, and also: it will cost several thousand dollars... So in my opinion, this cannot be a user friendly device to detect gluten, and you cannot carry easily (its weight: 8 KG).

AS I'm suffering now for undoubtedly I will buy it. Just yesterday I went to cafe in Dublin. I asked them if they have any gluten free food. they said yes. when I look at to their cupboard where they keep the food I was shocked. they have put just beside gluten free food, other food which is bread which is definitely not gluten free.
In addition I'm suffering at my own home as some of my family do not take my disease seriously and they contaminate my food with other not gluten free product.
