For 100 units of whole grain wheat, about 70 units of white flour results from the milling process. The rest is separately sold as wheat bran or wheat germ. Those 70 units of flour are about 10%- 15% protein, thus about 7 to 10 units of protein for

100 units of whole wheat. The protein is about 80% gluten, thus about 6 to 8 units of gluten for 100 units of whole wheat. Since one typically sees wheat flour as an ingredient, applying the 70% factor implies 8 to 12 units of gluten per 100 units of wheat flour. welcomes your comments below (registration is NOT required).
