Xanthan Gum Substitutes?

hi all!

I am pondering my choice to substitute gelatin in for xanthan gum in my bread recipes. I found somewhere that you could substitute it, but I'm wondering if the gelatin is what is causing all my really gummy breads? I have tried some of the "we promise it works" recipes from sites I got from here, but the only change I made was the gelatin.

Anybody with a chemistry degree (I only got through the required freshman level) have any thoughts? Or other bread makers?

Is there a possibility that the soy, oat, and tapioca flour can't play well together and make bread because of the high protein content in the soy flour?

I did have DH go get some xanthan gum so the next batch will be followed to the letter, including the xanthan gum. :rolleyes:

My schooling was biochemistry/molecular biology. Without going into too much detail, xanthan gum, guar gum and gelatin are all used as thickening/binding agents due to their interaction with other molecules, which is determined by molecular structure. However, both xanthan and guar gums are much more effective as a thickener/binder/plasticizer than gelatin. Gelatin is also not as versatile as a binder, depending on how/what it is mixed with, probably better used as a jelling agent or for making "gummy bears". Funny you mentioned "gummy bread" results.

Gelatin doesn't do a good job in imitating the binding/plastisizing/elasticizing quality of real gluten, whereas xanthan gum and guar gum can do ok. Open Original Shared Link You should wiki xanthan gum and guar gum too.

"Is there a possibility that the soy, oat, and tapioca flour can't play well together and make bread because of the high protein content in the soy flour?"

Protein from the soy or oats should play (mix) well with the starch (carbohydrate) from the tapioca. I don't see a problem there.

Maybe someone with more of a culinary background can share more.

Hopefully one day, someone will come up with a new additive that offers elastic properties more similar to real gluten. I'm craving crusty, chewy french bread...

Thanks for answering, you pretty much confirmed my hunch. I really appreciate it.

You're very welcome! :) Honestly, I've yet to make a decent gluten-free bread. For now, I just buy Udi's (thank goodness it's available). I'd love to be able to make a good bread, so feel free to let us know how it goes with the xanthan/guar gum. I'm searching for bread baking tips!

      Celiac attack confusion and anxiety

      By Colleen H · Posted

      Hi all ! Can a celiac attack be so intense that it causes your entire body to work in reverse? Meaning really bad pain,  neuropathy and muscle,  jaw pain,  the stomach issues , Horrible anxiety and confusion??  I had a Tums and you would think I ate poison. My jaw and stomach did not like it . Not the norm for me. Things that are simple are just out of control. Anyone ever have this happen??  I'm trying to figure out what I ate or did to bring on a celiac like attack. I had an idea before but yesterday I didn't have any gluten unless it was in a medication ?! Any positive suggestions ??  Thank you

      Gluten free stuff

      By Scott Adams · Posted

      The following two lists are very helpful for anyone who is gluten sensitive and needs to avoid gluten when shopping. It's very important to learn to read labels and understand sources of hidden gluten, and to know some general information about product labelling--for example in the USA if wheat is a possible allergen it must be declared on a product's ingredient label like this: Allergens: Wheat.

      Gluten free stuff

      By trents · Posted

      Tammy, in the food industry, "gluten free" doesn't mean the same thing as "no gluten". As Scott explained, the FDA (Food and Drug Administration) allows food companies to use the "gluten-free" label as long as the product does not contain more than 20 ppm (parts per million) of gluten. This number is based on studies the FDA did years ago to determine the reaction threshold for those with celiac disease. And the 20 ppm figure works for the majority of celiacs. There are those who are more sensitive, however, who still react to that amount. There is another, stricter standard known as "Certified Gluten Free" which was developed by a third party organization known as GFCO which requires not more than 10 ppm of gluten. So, when you see "GFCO" or "Certified Gluten Free" labels on food items you know they are manufactured with a stricter standard concerning gluten content. Having said all that, even though you may read the disclaimer on a food item that says the spices may contain wheat, barley or rye (the gluten grains), you should be able to trust that the amount of gluten the spices may contain is so small it allows the total product to meet the requirements of gluten free or certified gluten free labeling. I hope this helps.
