The retention of natural plus added vitamin B6 was 90 to 95% in corn meal and 100% in macaroni on shelf storage for 1 year at 100 F. and 50% relative humidity. When corn meal was cooked to corn bread, 100% of the vitamin B6 was recovered. When macaroni was cooked, about 50% of the vitamin B6 was found in the cooked macaroni and 50% in the drained cooking water. This loss of vitamin B6 in the drained water is similar to the loss of thiamine in the cooking of enriched macaroni.
