  There is a great interest in measuring the non-electronic component of
neutrinos from core collapse supernovae by observing, for the first time, also
neutral-current reactions. In order to assess the physics potential of the
ultra-pure scintillators in this respect, we study the entire expected energy
spectrum in the Borexino, KamLAND and SNO+ detectors. We examine the various
sources of uncertainties in the expectations, and in particular, those due to
specific detector features and to the relevant cross sections. We discuss the
possibility to identify the different neutrino flavors, and we quantify the
effect of confusion, due to other components of the energy spectrum, overlapped
with the neutral-current reactions of interest.
