Whole wheat bread is made of grains, and all starches and grains, especially refined starches (such as white rice, white bread, white noodles, biscuits, brewed refined meal packages, etc.) are acidic foods.
Whole wheat bread is different from ordinary bread made of refined flour (that is, flour ground by removing bran and nutritious subcutaneous colored parts from wheat grains). It is characterized by brownish color, and many small grains of wheat bran can be seen with naked eyes. The texture is rough, but it has aroma.
Because its nutritional value is higher than that of white bread, and it is rich in crude fiber, vitamin E, zinc, potassium and other minerals, it is very popular abroad, and it is rich in B vitamins, so microorganisms especially like it, so it is more prone to mildew than ordinary bread.
