Can anyone out there explain to me the difference between soy powder, soy protein isolite and soy flour. Are any of them interchangeable in a recipe? I am having trouble finding the soy protein isolite and wonder if I can just use the soy powder.

Do you live in Vancouver? Capers sells soy isolate repackaged under their own label in plastic bags. They also sell soy powder and flour. Most natural and nutrition performance stores sell it as a protein shake.

Here's the info from an old post of mine...

There have been a couple of questions over the past few days about the difference between various soy derived "powders."

Here are the differences. Because the protein content varies (which makes the carb content higher or lower), the three are not interchangeable, especially if used in cooking.

Soy ingredients - soy flour, soy protein concentrate and isolated soy protein -- that go into soyfoods all contain soy protein. Soy protein is always made from soy flakes.

Soy flour, which is 50% protein (based on dry weight), is ground from soy flakes to the desired particle size, smooth or course.
Soy protein concentrate, which is 70% protein(based on dry weight), is made by processing soy flakes to remove some of the sugar that naturally occurs in soy.

Soy protein concentrate can be processed two different ways:

·Soy flakes can be washed with water, then dried to make the finished product.
·Or alcohol can be added to soy flakes to dissolve sugars and other alcohol-soluble substances.

Unfortunately, both alcohol processing and excessive water washing remove most of the isoflavones naturally present in soy
flakes.

The third soy ingredient is isolated soy protein. What does isolated mean? Simply that once the protein is manufactured using water to remove most of the sugar in the soy flakes, the protein is then precipitated and dried. What you're left with is an ingredient that is 90% protein (based on dry weight)- a much higher percentage than you'll find in soy flour or soy protein concentrate, and a number that makes isolated soy protein the most concentrated form of soy protein there is.

There's a lot of strong negatives about using soy isolates, especially for women. Here's a couple of sites with that information. www.westonaprice.org and www.powerhealth.net

Thanks for the info...I had not heard of any dangers in using this ingredient. I will check out the web sites. I was just interested in the soy protein isolates because it is an ingredient in some of the baking recipes that I have looked at.

I live in Powell River and I can not find it here...but I do get to Vancouver Island quite often, so I will look over there the next time I visit my daughters.

Good then! There is a Capers in Victoria.
