We improve our previous QCD sum rule calculation on g(KN Lambda) and g(KN S
igma) coupling constants by including the contributions from higher dimensi
onal condensates, [(q) over bar g(s)sigma . Gq] and [(q) over bar q][(alpha
(s)/pi)G(2)], in the OPE. It is found that the contribution of these conden
sates is non-negligible compared to that of the quark condensates. Using a
best-fit analysis we find \g(KN Lambda)\ = 2.49+/-1.25 and \g(KN Sigma)\ =
0.395+/-0.377.
