Xanthan Gum And Corn Starch

I want to get into baking different breads and cookies.

What is the difference between Xanthan Gum and gluten free Corn Starch?

They are both used as thickeners so can I use the corn starch instead of the xanthan gum? Or is corn starch just mainly for soups and gravies?

Thank you :)

I believe that xanthan gum is used as a binder especially if using rice flour. It isn't a thickener. Corn starch can be used for thickening gravy, puddings etc., but also makes flour mixes lighter. You can not use it in place of xanthan gum. I think you can use guar gum and xanthan gum interchangeably.

Open Original Shared Link is a thickener (it increases the viscosity of liquids) and emulsifier (it keeps things from separating). A very small amount can add much needed structure to gluten free baked goods.

Open Original Shared Link is also sometimes used as a binder, but it has nowhere near the power that xanthan gum has. Adding a teaspoon of xanthan to a batch of cookies will completely change it. Adding a teaspoon of cornstarch will do nothing at all. Xanthan also thickens with no heat, while cornstarch has to be heated to thicken. Xanthan will not separate from a liquid when allowed to stand, but cornstarch definitely will.

Don't try to sub cornstarch for xanthan. A better sub would be guar gum, a similar product to xanthan gum.

Hope this helps.

Thank you so much for the replies :D

I have been cooking a lot but really want to try making some different kinds of breads and cookies. Some of the cooking products are a little confusing so I appreciate the input. Im gonna print this page off and put it with my cooking/baking notes.

Thanks again! :)

      Coeliac or not coeliac

      Hi @CC90 Ah... that is very interesting. Although it is very annoying for you to have to go through it all again, I would say that almost sounds like an admission that they didn't look far enough last time? I could be wrong, but I would not be at all surprised if they find something on the next attempt. Coeliac damage can be very patchy, as I understand...

      Coeliac or not coeliac

      Hi Cristiana Yes I've had the biopsy results showing normal villi and intestinal mucosa. The repeat endoscopy (requested by the gastro doc) would be to take samples from further into the intestine than the previous endoscopy reached.

      Coeliac or not coeliac

      Transglutaminase IgA is the gold-standard blood test for celiac disease. Sensitivity of over 90% and specificity of 95–99%. It rarely produces false positives. An elevated level means your immune system is reacting to gluten. Non-Celiac Gluten Sensitivity (NCGS) does not typically cause high levels of tTG-IgA. Unfortunately the protocols for a diagnosis o...

      Do Antibiotics in Babies Increase Celiac Disease Risk Later in Life? (+Video)

      In Addison’s disease, autoimmmune adrenal cortex disease adrenal glands don't make enough cortisol. At 12, it is usually caused by an autoimmune attack. It has a strong genetic link to the HLA-DQ8 gene. After 12 gluten free and 14 years on prednisone for adrenal insufficiency (symptoms like you describe from 1984 until 2014) I recently removed all c...

      Hi @CC90 Ah... that is very interesting.  Although it is very annoying for you to have to go through it all again, I would say that almost sounds like an admission that they didn't look far enough last time?   I could be wrong, but I would not be at all surprised if they find something on the next attempt.  Coeliac damage can be very patchy, as I understand it, so that's why my own gastroenterologist always likes to point out that he's taken lots of samples!  In the kindest possible way (you don't want to upset the person doing the procedure!) I'd be inclined to tell them what happened last time and to ask them in person to take samples lower down, as  if your health system is anything like the one in my country, communication between GPs, consultants and hospitals isn't always very good.  You don't want the same mistake to be made again. You say that your first endoscopy was traumatic?  May I ask, looking at your spelling of coeliac, was this done at an NHS hospital in England?  The reason for the question is that one of my NHS diagnosed friends was not automatically offered a sedative and managed without one.  Inspired by her, I tried to have an endoscopy one time, in a private setting, without one, so that I could recover quicker, but I had to request sedative in the end it was so uncomfortable.    I am sorry that you will have to go through a gluten challenge again but to make things easier, ensure you eat things containing gluten that you will miss should you have to go gluten free one day. 😂 I was told to eat 2 slices of normal wholemeal bread or the equivalent every day in the weeks before , but I also opted for Weetabix and dozens of Penguin chocolate biscuits.  (I had a very tight headache across my temple for days before the procedure, which I thought was interesting as I had that frequently growing up. - must have been a coeliac symptom!)  Anyway, I do hope you soon get the answers you are looking for and do keep us posted.

It rarely produces false positives.  An elevated level means your immune system is reacting to gluten.  Non-Celiac Gluten Sensitivity (NCGS) does not typically cause high levels of tTG-IgA. Unfortunately the protocols for a diagnosis of Celiac Disease are aimed at proving you don't have it, leaving you twisting in the wind. Genetic testing and improvement on a trial gluten free diet, also avoiding milk protein, will likely show improvement in short order if it is Celiac; but will that satisfy the medical system for a diagnosis? If you do end up scheduling a repeat endoscopy, be sure to eat up to 10 grams of gluten for 8 - 12 weeks.  You want  to create maximum damage. Not a medical opinion, but my vote is yes.

      Hello @CC90 Can I just ask a question: have you actually been told that your biopsy were normal, or just that your stomach, duodenum and small intestine looked normal? The reason I ask is that when I had my endoscopy, I was told everything looked normal.  My TTG score was completely through the roof at the time, greater than 100 which was then the cut off max. for my local lab.  Yet when my biopsy results came back, I was told I was stage 3 on the Marsh scale.  I've come across the same thing with at least one other person on this forum who was told everything looked normal, but the report was not talking about the actual biopsy samples, which had to be looked at through a microscope and came back abnormal.
