榨菜加工中亚硝酸盐含量的动态研究

对涪陵榨菜现行两种加工工艺———风脱水、盐脱水加工中亚硝酸盐的含量进行了研究,旨在弄清两种工艺加工中榨菜亚硝酸盐的含量变化规律。结果表明:榨菜加工过程中,亚硝酸盐含量变化呈规律性变化,盐脱水工艺其亚硝酸盐含量呈下降趋势;而风脱水工艺亚硝酸盐含量呈下降、上升、再下降的变化规律;榨菜经两种工艺加工成熟后,亚硝酸盐含量低微,食用是安全的。

Study of nitrite content change trends in Fuling pickle''s processing process

This article studies Fuling pickles' nitrite contents,which are produced by two producing processes,dehydration by wind and dehydration by salt.The aim is to find out its nitrite content change rule by the processes.The study results indicate that the pickles' nitrite contents have a regular trend.In the process of dehydration by salt,their contents are decreasing;but in the process of dehydration by wind,their contents are decreasing,increasing and decreasing.So it was found that their nitrite contents are very low if the pickles are prepared by the two processes.
