The coupling constants of K and \ensuremathπ mesons with the octet baryons are studied in light cone QCD sum rules taking into account SU(3)f flavor symmetry breaking effects, but keeping the SU(2) isospin symmetry intact. It is shown that, in the SU(3)f flavor symmetry breaking case, all of the couplings can be written in terms of four universal functions instead of F and D couplings which exist in the SU(3)f symmetry case. A comparison of our results of kaon and pion-baryon couplings with existing theoretical and experimental results in the literature is performed.
