The stability of enrichment vitamins was examined in samples collected during various stages in bread and cookie production. Whereas riboflavin and niacin seemed to be quite stable in both products, the stability of thiamin differed widely. Thiamin was quite stable in bread, but about three-fourths of the thiamin in cookies was destroyed during baking. Compared to fresh products, shelf-stored products (bread for one week; cookies for four weeks) showed minimal additional loss of the three vitamins.
