Study on the Factors Influencing the Nitrite Content in Vegetables

The changes of nitrite content in vegetables under different storage time and storage temperature,different food processing methods and different pre-treatment conditions and so on were discussed.The results showed that,the content of nitrite gradually increased with time,and would decrease after the maximum value.The nitrite contents in different vegetables were different with temperature changing.Blanching treatment could reduce the content of nitrite,and nitrite content in soaking would increase.When vegetables were fried or cooked,the nitrite content would be reduced,the nitrite content of cooked vegetables was lower than that of fried vegetables.
