Regular corn meal is a whole ground corn meal that is full fat and can become rancid because of the high oil content. It can be stored in a refrigerator or freezer up to 6 months and slightly less at ambient temperature. Bolted corn meal has had a portion of the bran and germ removed in the milling process. Because a portion of the germ remains, the remaining fat content can cause this product to become rancid. It can be stored in a refrigerator or freezer up to 8 months and slightly less at ambient temperatures. Degermed corn meal has had most of the germ and bran removed during the milling process. Degermed corn meal is lower in fat. It can be stored at a room temperature of less than 21Â°C (70Â°F) for 12 months. Storage time would be less when temperatures are more than 21Â°C (70Â°F). Unenriched corn meal contains no added vitamins or minerals. Enriched corn meal contains added vitamins and minerals. It is enriched with thiamin, riboflavin, niacin, folic acid, and iron in harmless and assimilable form. It may contain calcium and vitamin D in a harmless and assimilable form. Self-rising corn meal contains added leavening agents, which include baking soda, salt, and an acid-reacting phosphate.
