Effects of Acid Concentration on Generation Amount of Nitrite in Pickled Cucumber

[Objective] The research aimed to study the effects of acid concentration on generation amount of nitrite in pickled cucumber.[Method] Taking the "Huabei" and "Occident" cucumbers pickled with the edible acetic acid as the experiment materials,the effects of acid concentration on generation amount of nitrite in pickled cucumber were studied.[Result] The concentration of nitrite declined with the increasing of the acid concentration,and a little amount of nitrite was produced in the first day,and the maximum of nitrite was observed at the day of 2-3.It was a steady and lower trend of the concentration of nitrite after the day of 5.The nitrite generation amount in the "Huabei" cucumber was lower compared with the "Occident" cucumber,and the nitrite generation amount in the low temperature was lower than the normal temperature.[Conclusion] A little amount of nitrite was produced by properly increasing the acid concentration of cucumber after the day of 5.
