  We report on studies of untriggered two-particle angular correlations of
identified particles (pions, kaons and protons) measured in proton-proton
collisions at center-of-mass energy sqrt{s}=7 TeV recorded by ALICE at the LHC.
These type of studies are sensitive to a wide range of correlations which arise
from different physics mechanisms, each of them having a unique structure in
DeltaEta-DeltaPhi space. The correlations of particles with different quark
content and flavor are sensitive to various conservation laws. The study of
these correlations is the main goal of this analysis. The results confirm that
these laws strongly influence the shape of the correlation functions for
different particle types and must be taken into account while analysing the
data. Moreover, we verify their implementation using two Monte Carlo event
generators and we found that the analyzed models do not reproduce the measured
correlations for protons.
