Grain products; meets a large part of the daily energy requirement. It also contains high amounts of water-soluble vitamins B1, B2 and B6. However, the bioavailability of these vitamins are different. The aim of this study is to investigate the bioaccessibility of vitamins B1, B2 and B6 in white, whole wheat, whole wheat and oat bread in our diet in simulated mouth, stomach and small intestine environment. Vitamin contents were determined by High Performance Liquid Chromatography (HPLC). The bioaccessibility of vitamin B1 was between 45% and 73%, while the bioaccessibility of vitamin B2 was between 56% and 75%. The lowest bioaccessibility was found in oat bread in vitamins B1 and B2. In vitamin B6, bioaccessibility was between 56% and 67%. The highest bioaccessibility was found in PN form and the lowest in PL and PM form. In addition, the bioaccessibility of vitamins B1, B2 and B6 in oat bread was lower than other bread types. As a result, vitamin B levels obtained from bread do not correlate with our daily energy needs. Therefore, in our daily nutrition, foods rich in B group vitamins can be consumed with bread.
