Peanut is also used as peanut flour, concentrates, and isolates. These serve as potential extenders in many meat formulations. Peanut flour has been used to replace part or all of wheat flour or corn meal in making various types of breads and other bakery products. Peanut protein isolates have for many years been used in the manufacture of imitation milk as an extender to cow or buffalo milk. Peanut protein isolate and peanut oil have been used to make cheese analogs for the production of cream cheese and cheese spread products. The major use of peanut is for grinding into peanut butter.
