ALICE is well suited for strange particles production studies since it has very good reconstruction capabilities in the low transverse momentum ($p_{t}$) region and it also allows to extend the identification up to quite high $p_{t}$. Charged strange mesons ($\kp$, $\km$,) are reconstructed via energy loss measurements whereas neutral strange mesons ($\ks$) and strange hyperons ($\lam$, $\Xi$, $\Omega$) are identified via vertex reconstruction. All these particles carry important information: first, the measurement of production yields and the particle ratio within the statistical models can help to understand the medium created and secondly the dynamics at intermediate $p_{t}$ investigated via the baryon over meson ratio ($\lam / \ks$) allows a better understanding of the hadronization mechanisms and of the underlying event processes. We present these two aspects of the strange particles analysis in pp collisions using simulated data.
