摘要
目的探讨市场上常见预包装食品中钠的含量及变化趋势。方法于2012年调查市场预包装食品营养标签，记录和分析了1279条预包装食品钠含量的数据，按照逐级归类方法对每类食品钠含量进行统计，获得中位数及变化范围，并与1991～2004年的预包装食品钠含量数据进行比较。结果在31类预包装食品中，6类食品钠含量〉500mg／100g，属于高钠食品，其中即食食品（2500mg／100g）、方便面（1900mg／100g）等钠含量中位数最高。与1991～2004年数据相比，13类食品钠含量中位数增加，其中蛋糕、方便面、干果、液态奶及酸奶等5类显著增加。结论部分预包装食品钠含量呈上升趋势。
Objective To collect the data on the sodium content of Chinese per- packaged foods, and to analyze the variation trend of sodium content. Methods 1279 data on the sodium content of per-packaged foods in all were recorded and analyzed through the investigation of per-packaged food nutrition labels, and were categorized into 31 varieties. Median sodium content and variation were calculated for each variety and compared with 2004 sodium content data on China Food Composition. Results there are 6 per-packaged foods varieties has the median sodium content more than 500 rag/100 g. The food varieties with the highest mean sodium content were ready-to-eat food（2500 rag/ 100 g） , followed by instant noodles （1900 mg/100 g）. Compared with 1991 -2004 per- packaged foods sodium content, 13 varieties had medium sodium content that increased, and 5 varieties increased significantly, such as cake, liquid milk, instant noodles etc. Conclusion The survey show that sodium content of some per-packaged food increased.
