Non-Abelian energy loss in quark-gluon plasma is shown to lead to novel hadron ratio suppression patterns in ultrarelativistic nuclear collisions. We apply recent (GLV) estimates for the gluon radiative energy loss, which increases linearly with the jet energy up to E < 20 GeV and depends quadratically on the nuclear radius, R. The K+/n+ ratio is found to be most sensitive to the initial density of the plasma.
