Effects of Different Storage Conditions on the Content of Nitrite in Fruits and Vegetables

This paper is on the change of nitrite content of cahhases,cucamber,hidney beans and winter melon under different storofe temperature and storage time.The results showed that:(1) whether it is at room temperature or in cold conditions,the nitrite content of 4 kinds of fruit and vegetables increased gradually with the extension of storage time;(2) Under the same storage time,the nitrite content and its change speed in fruits and vegetables stored under lower temperature were both obviously lower than that stored under room temperature.(3) Three low-temperature processing,the nitrite content from low to high is preservation of Box refrigeration frozen,cold preservation of film and 4 ℃ refrigerator cold;(4) The nitrite contents and its change speed in fruits and vegetables are significant of different varieties of vegetables.
