We study the SU(3)×{}SU(3) Skyrme model with explicit chiral- and flavor-symmetry-breaking terms. We evaluate the SU(3)-symmetric meson-baryon coupling-constant ratio α, SU(3) mass breaking in the octet and decuplet, and the ΔI=1 part of the electromagnetic mass splitting in baryons. The theoretical numbers are in reasonable agreement with the experimental values.
