Abstract: The relationship between change pattern of nitrate, nitrite, microorgnism in the process of pickling of cowpea and salt concentration,temperature was studied. The relationship between the composition of pectic substance fractions and the texture of pickled cowpea during pickling was investigated. The results showed that nitrate content declined and there was nitrite peak. Colony forming units increased and then declined. Pectin content declined and soluble pectin increased. Hardness declined and fracturability increased and then declined. There was relationship between texture of pickled cowpea and pectin content and composition.

Key words:  , cowpea; nitrate; nitrite; pectin; texture;
