Corn meal that is degerminated
Unbleached wheat flour IS bleached by oxygen in the air during an aging process. Bleached flour uses chemicals (which may be dangerous to your health) to speed up the process. Unbleached flour will be off-white in color but nutritionally, bleached and unbleached flours are equivalent (very little nutritional value). In BOTh these flours the bran and germ have been removed (degerminated), making it a processed white flour.
Cornmeal can typically last for about 1 to 2 years when stored properly in a cool, dry place, but its shelf life can vary based on whether it's whole grain or degerminated. Signs that cornmeal is too old include an off smell, discoloration, or the presence of mold or insects. If it has a rancid or bitter taste, it's best to discard it. Always check the expiration date or do a smell and taste test before using older cornmeal.
