Possibility of experimental identification of QCD-instantons in high energy collisions is studied by means of correlations analysis in final states. Instanton-induced processes amplitudes are performed in the framework of QCD in Gauss approximation. Hadronization is taken into account by Monte-Carlo method. Obtained results can be used as additional criterions of QCD-instanton identification at HERA (DESY). Unlike previous results in this report we consider also nonzero quarks modes contribution...
