Want to reverse engineer low carb hi fiber wrap

I buy a brand of tortillas that is marketed as low carb high fiber and whole wheat. I would like to try my hand at making them at home. One of the reasons I like them is that they are rather flexible (all the gum,probably). I'm sure they'd taste even better.

Ingredients: Water,oat fiber,WW flour,soy flour,vital wheat gluten,canola oil,

Less than 2%: baking powder,sea salt,guar gum.citric acid,yeast,xanthan gum, and the preservatives l-cysteine and calcium proprionate.

Not the worst ingredient list I've seen though I usually am the flour,water,yeast,salt kind of breadmaker.

Any guess as to the ratios? I have never worked with the fibers but I have been able to source oat fiber,xanthan and guar gum.WW flour and soy flour are readily available.

Gluten free cooks use the gums in a lot of gluten free baked products. Can your expertise help with that?

The nutritional counter says:

1 tortilla 62 g

Calories 80

Total Fat 3 g

Total Carb 18g

Dietary Fiber 12g

Sugar 1 g

Protein 8 g

Constructive ideas appreciated. Experienced tortilla makers (I've only made corn tortillas) and roti makers may have some excellent insight into making these tortillas.

This may be a multi-specialty, multi-cultural project-my favorite kind!

Now if only some of the tortilla makers,gluten-free cooks and perhaps people familiar with using  oat fiber would chime in. I may post a separate inquiry on just that subject elsewhere. It is a big world and a lot of people are on this forum.I hope someone can help.

is a British product that I picked up at an import shop here in Japan...I don't remember the exact price, but it was outrageously high for an ingredient I was buying 'on spec', with no particular recipe in mind. It was a nice, tasty addition to mixed-grain loaves and seemed to add some interest to my rye starter in small quantities...

I know oat and barley bran are high-fiber, and good sources of "beta-D-glucans" which I think is what "oat fiber" refers to in an ingredients list...I have no idea whether that means the manufacturer has used oat or barley bran in the recipe, or whether they have derived the beta-D-glucans by some 'processing' of the bran. I'd be game to try the bran itself, but it MIGHT interfere with gluten development...perhaps that's why the ingredients specify inclusion of VWG? What do you think?

I'm just guessing, but hope this helps...

I'm interested in this as an intellectual exercise, so I did some calculations.

First of all, the percent weight of fiber in the tortilla is 12/62, or 19%.  According to the USDA database, the percent fiber in oat bran is 15.4%, in hard winter wheat is 12%, and in soy flour is 16%.  Therefore, oat fiber is the required source rather than oat bran.  According to Honeyville, oat fiber is 93% fiber.  For a 62g tortilla, there cannot be more than 20g of oat fiber, or the fiber content of the tortilla will exceed 19%.  Furthermore, the ingredients will be present in descending quantity in the order given.  As a wild-assed guess, I calculated the outcome of 18g of oat fiber, 14g of hard winter wheat, and 10g of low fat soy flour.  The total weight of those is 42g, which leaves 20g for water, gluten, oil, and the two gums.   If it were all water, that would be roughly 50% hydration, counting fiber as a flour.

The fiber content of the 18:14:10 was 20% vs the tortilla value of 19%.

The  carbohydrate content of the 18:14:10 was 30% vs the tortilla value of 29%.

The lipid content of the 18:14:10 was 1% vs the tortilla value of 4%, but the oil will add lipids.

The protein content of the 18:14:10 was 6% vs the tortilla value of 13%, but the gluten will add protein.

The caloric content of the 18:14:10 was 86 vs the tortilla value of 80.

According to the KAF forum, you only need about a teaspoon of gums per cup of flour.

 I had googled the nutritional data of all the major compnents,as you did,and contemplated the relationaship of the percentages. I was just about to sit down and start cranking out some of the math when I refreshed the screen. Thank you! I can do it but it does not come easy!

Gluten has 21g protein/ounce(28 g). If I need to make up the difference in the protein from 6% in the 18:14:10 to 13% for the tortilla, then that should be about 4g wheat gluten needed.This would add 14 calories for a caloric total of 100. The oil would add a few more calories so, while not being exact, I think this is a start to getting close.

So a starting recipe:

18 g oat fiber

14 g WW flour

10 g lowfat soy flour

4 g wheat gluten

1 tsp(2g) combined xanthan gum and guar gum

 about 16 g oil and water

This is only about 38% hydration (16g water/42g flours,fiber,gluten)-not counting the oil- and these are very thirsty types of flours. That will make for a tough roll out.

Is there a typical amount of weight loss through evaporation for a tortilla?  More water can then be added up front. Our calculations are based on the final weight of the tortilla. It might have started life a little heavier and the ratios may need some adjusting.

Time to start accumulating some oat fiber.

Water comes first on the list, so there has to be more water than oat fiber.  I bet if you add enough water to make it workable then you can scale the entire thing to size once you get the thing to not fall apart using the gluten and gums.  I'm sure more fine-tuning can be done on the three main solids, too, maybe assisted by taste.  I just picked nice even numbers for my calculations.
