Is glucose syrup gluten-free?
Posted on September 2nd, 2008 by alison
Glucose syrup is a liquid sweetener used in candy, desserts and that ice cream in the picture. It can made from any starch. In the United States, corn is used, but in Europe it is usually derived from wheat. One would assume that the wheat-based glucose contains gluten, but in fact, glucose syrup made from wheat starch is considered gluten-free.
I confirmed this with Shelley Case, the go-to gluten-free dietician and author of Gluten Free Diet: A Comprehensive Resource Guide. In an email to me she said:
Glucose syrup can be derived from a variety of starches including wheat. Corn is the most common however Europe uses wheat more frequently. The glucose syrups are highly processed and purified and R5 elisa tests have found the majority to contain very little residual gluten if any. The European Food Safety put out a report on the safety of glucose syrups. Here is the link for more info:
Based on the FDA proposed gluten-free labeling regulation a product can be derived from a gluten-containing grain such as wheat based glucose syrup and be labeled gluten-free yet the ingredients could say glucose syrup (wheat) provided it is under 20 parts per million (ppm). This will be very confusing for patients as we teach them to avoid wheat and yet a product like glucose syrup may have no or very little residual gluten and be labeled gluten free.”
And just this month, a new gluten-free study from Finland was released. In the study they determined that it was safe for celiac patients to consume glucose syrup and other starch hydrolysates derived from wheat. Here is the summary of the report:
Background: Wheat-based starch hydrolysates such as glucose syrups, dextrose and maltodextrins are found in more than 50% of European processed food. These products contain low amounts of residual gluten, and it has been questioned whether they are safe for coeliac disease patients.
Aim: Our aim was to investigate whether coeliac disease patients can safely consume wheat-based starch hydrolysate products.
Methods: This randomized, double-blind, placebo-controlled, prospective follow-up study involved 90 coeliac disease patients in remission randomized to consume glucose syrups, maltodextrins or placebo for 24 weeks. Small bowel mucosal morphology and inflammation, symptoms, coeliac serology and malabsorption laboratory data were evaluated at baseline and at the end of the study.
Results: Daily ingestion of wheat-based starch hydrolysates, glucose syrups and maltodextrins, had no deleterious effect on small-bowel mucosal villous architecture or inflammation in coeliac disease patients when compared to the placebo group. Neither were there any significant differences in gastrointestinal symptoms, serology or malabsorption parameters after 24 weeks.
Conclusions: Wheat-based starch hydrolysates, glucose syrups and maltodextrins did not have harmful effect on coeliac disease patients. Coeliac patients can thus safely continue to consume these products.
I’d heard this information before, but I’m glad I happened upon your website so now I have it offically and in print. Thanks!

I get leary of comments like
“The glucose syrups are highly processed and purified and R5 elisa tests have found the majority to contain very little residual gluten if any.”
The majority of? What about those few that DO contain residual gluten. Some of us are extremely sensitive to gluten and react to what others do not react to. Did they have extreme reactors in their study? You can only generalize your results to the population you took your sample from. So, if their pool had no extreme reactors and did not use any of the minority foods - this article gives a false sense of security.

I had decided it was safe to eat a Cadbury Creme Egg today based on information from this website while researching Glucose Syrup (wheat) and unfortunately for me I had a horrible gluten reaction. No matter how “safe” it might be for some, it isn’t for everyone. If you have a sensitive gluten reaction DO NOT eat glucose syrup derived from wheat. The risk isn’t worth the stomach ache!
Adrienne,
I don’t trust Cadbury Creme Eggs — in my last year’s article, Hershey would not say that they are gluten-free, which could come from their natural flavors. See the article here: Celebrating Easter Gluten Free and Allergen Free.
I am new to the gluten free world. My son would be considered an extreme reactor, at least I’m assuming that after his reation from chewing hubba bubba bubble gum tape. Which says on the lable is gluten free, but looking at the ingredients says wheat glucose syrup….. I’m kinda confused about the whole thing & very frustrated.

Nichol,
Was the Hubba Bubba Bubble Gum Tape bought in the U.S.? I haven’t seen wheat glucose syrup listed as an ingredient, unless they recently changed the ingredients.
I’m not celiac but wheat intolerant and I discovered wheat glucose syrup reading the ingredients of packets to things like, licorice, marshmellows and sesame seed bars after I had reactions to them. Given that western doctors just tell me I have irritable bowel syndrome which personally I reckon is akin to me going to them with an nasty rash and being told I have sratch the itch syndrome. You know I told them the symptoms already and they repeat it back and call it a syndrome mind you they know nothing else. It’s probably an irritation, maybe mucousy, may be from a reation to something I ate they say???? As for this ‘information’ assuring us that in fact wheat glucose syrup is so refined it hardly contains any gluton at all, how bloody reassuring is that??? Clearly for me I am having a reaction to this therefore it is highly likely that it is another aspect of the wheat alltogether, I suspect it is the refining itself. I know a baker that makes bread the very old fashioned way (god I miss delicious fresh soft bread) he ferments the wheat grain and believes this process is what’s needed to stop the reaction I have. It makes sense in that I react badly to milk and yet am fine with yoghurt. I need to test out the bread theory. We all need better information on packets and I’d like to know if there is any kind of lobby group to get producers to use a wider variety of sugar syrups like rice or agave. Does anyone know anything like this???
Kirsten,
Do you live in the U.S. or Europe? From what I understand, wheat glucose syrup is used far more commonly in Europe than in the U.S. I rarely see it as an ingredient here.
Hi.
I am sorry to tell you that i can not eat glucose sirup made of wheat.. I have tried it so many times, and it is not good for me at all.

I’ve living GF for 18 months now, and I’m not entirely sure where I am on the scale of intolerant through to Coeliac (haven’t had a biopsy, just the blood tests). Fortunately, I didn’t suffer the worst symptoms (no skin reactions) but did have bloating, lethargy and memory problems.
I find that I can tolerate wheat-derived glucose syrup quite well. Though usually if I do eat a food containing it, it’s something quite small like a single candy bar. How I might react to eating a lot of wheat based syrup is another question altogether.
It might also be worth noting that I’m in Australia, where food manufacturing standards are quite high. It may be possible that the wheat based glucose syrup has been manufactured to a higher standard than in other countries.
I guess my only advice is for people whose level of reaction isn’t too severe, is don’t rule out wheat-based glucose syrup necessarily. But if you do try foods with it, start with small portions.
