Outline of Final Research Achievements

A method to increase sulforaphane, a phytochemical included in cruciferous vegetables, was studied. The concentration of sulforaphane in broccoli buds sealed in a high-barrier pouch and stored for 2 d was 2.3 times higher than that stored in the air. In contrast, The concentration was not increased under the atmosphere including low O2 and low CO2. The atmosphere including high O2 and high CO2 was also not effective for increasing the concentration. Therefore, it was concluded that an atmosphere including low O2 and high CO2 have to be created to increase sulforaphane.
