Increased Sulforaphane Concentration in Brussels Sprout Following High Hydrostatic Pressure Treatment

Abstract

High hydrostatic pressure (HHP) treatment was used to increase the concentration of sulforaphane in Brussels sprout, a cruciferous vegetable known to have health benefits. The highest concentration of sulforaphane was 1021.8 mu mol per kg fresh weight of Brussels sprouts after HHP treatment at 500 MPa, which corresponded to a 317% increase compared to the HHP-untreated control.
