Brussels sprouts seedlings with different water content (wc = 4.8–89.4{\%}) and water activity (aw = 0.17–0.97) were pressurized at selected pressures between 200 and 800 MPa (5 °C and 3 min), thereby affecting pressure-induced enzyme denaturation, molecular diffusion, and cell permeability differently. The myrosinase activity and intact glucosinolate content in the dry seedlings (wc < 14{\%}) was not affected by the applied pressure treatments. Water adsorption (duration of 5 days) prior to HPP resulted in a decreased initial myrosinase activity due to changed plant cell permeability.

The treatment is acknowledged for the ability to give products longer shelf life concomitant with a high nutritional quality and fresh appearance. Upon HPP of cruciferous plants it is important to have a special focus on the glucosinolate-myrosinase system, since sub-optimal pre-treatment and/or processing parameters can affect the food quality negatively.
