We constrain the energy spectra of neutrinos from core collapse supernovae through the abundances of 11B and 7Li in the context of galactic chemical evolution. We show that the temperatures of mu- and tau-neutrinos are constrained to the range (4.8,6.6)MeV for zero chemical potential. These temperatures decrease by about 10 percent for realistic non- zero chemical potentials.
