The electroproduction of pions and kaons at the kinematics of quasi-elastic knockout is a powerful tool for investigation of mesonic cloud. A model of scalar qq(3P0) fluctuation in the non-trivial QCD vacuum is used to calculate pion and kaon momentum distributions in the channels NB+p, B = N, D, N*, N**, and NY + K, Y=L, S0.
