We present a model independent approach to FFs, which allows to determine uniquely the non-singlet combination (Du-Dd)K++K- of the kaon FFs, independently in the three different processes of kaon inclusive production: e+e- annihilation, pp-collisions and lN semi-inclusive DIS. Only C and SU(2) invariances are used and no assumptions on FFs and PDFs, the result holds in any order in QCD. The non-singlets obtained in this way, would allow to test the commonly used assumptions in global fit analysis and to test universality. This method is applied to kaon production data in e+e-→ K+X, K=K^±, K0s and (Du-Dd)K++K- is obtained without any assumptions. This result is compared to the existing parametrizations, obtained in global fit analysis.
