We present a calculation of generalized baryon form factors in the framework of three-flavor covariant baryon chiral perturbation theory at leading one-loop order, necessary for the calculation of the first moments of generalized parton distribution functions. The formulae we derive can be used to guide the chiral extrapolation of three-flavor lattice calculations of the corresponding QCD matrix elements.
