Abstract:To study effects of different storage conditions on nitrite content of preserved meat， sausage， ham sausage， westen pork ham and smoked meat. The variation trend of nitrite content of five meat products along with storage time was studied， when stored in the freezing temperature（-18 ℃）， refrigeration temperature（4 ℃）， room temperature（25 ℃）.The result indicated that the nitrite content of meat products declined with the exten－ sion of the storage time. The nitrite content of meat products stored in room temperature was lower than that in refrigeration， and the nitrite content of meat products stored in refrigeration was lower than that in freezing.
