Could someone please clear up the following for me?

Suppose we start with a cloud of hydrogen, with a total baryon number
equal to the number of hydrogen atoms present.  As this cloud goes from
protosun -> star -> supernovae -> neutron star, baryon number is conserved.
Fine and dandy.  Now the neutron star collapses into a black hole.  I guess
I ought to assume the black hole still "remembers" the baryon number somehow.
Now, according to Hawking, the black hole evaporates into "radiation".
Does it "evaporate" into light?  Or did he mean "particle radiation"?
Is baryon number conserved in this last stage?
