Effect of Different Pickled Condition on the Content of Nitrate and Nitrite in Cabbage
Contents of nitrate and nitrite in cabbage under different pickled conditions were studied .The result showed: The content of nitrite and nitrate in cabbage were significantly different under different picked condition .The content of nitrite and nitrate was 70 g/kg<100 g/kg<20 g/kg<50 g/kg in cabbage under different pickled salinity;the content of nitrite was refrigeration (-20℃)<room temperature ( 20℃)<cool temperature ( 4℃) in different temperature pickled condition , and the content of nitrate in cabbage under the cool temperature ( 4℃) was higher , but there was no difference between that under refrigera-tion(-20℃) and room temperature ( 20℃) .However , the contents of nitrate and nitrite in pickled cab-bage were unconspicuous ,which were pickled in different incubate pH condition .Therefore , the content of nitrate and nitrite was low in 7%of salinity and kept in -20℃, which was safer to eat .
