In contrast to the aforementioned studies, Schuster-Gajzágó
et al. (2006) exposed white mustard seed to RF with the intention
of inactivating the endogenous enzyme myrosinase which was
responsible for the development of pungent sharp flavour. In addition, these workers also assessed the impact of RF on compounds
with health beneficial effects found in these seeds. They found RF
could effectively inactivate myrosinase to a sufficient level to inhibit pungent flavour development while causing no damage to compounds of nutritional significance. Previously Cserhalmi et al.
(2001) had also reported successful reduction of pungency of yellow mustard seed after treatment in a 10 kW, 13.5 MHz, RF system.
The RF treated yellow mustard seed (Sinapsis alba L. cv Tilney)
exhibited a small reduction of fat binding ability and nitrogen solubility index but the water binding ability and emulsifying activity
practically did not change as a result of treatment and the emulsion stability increased.
