【摘要】：目的了解广州市预包装食品钠含量现状及消费者低盐饮食认知情况。方法抽取广州市4间连锁超市,记录783种预包装食品营养标签上的钠含量标示情况;随机抽取超市消费者271名,通过问卷调查其低盐饮食认知情况。结果预包装食品钠含量总标示率为99.36%,各类预包装食品的钠含量范围和中位值均有较大的差异,榨菜、方便面和肉制品的钠含量中位数分别为2 360 mg/100 g、1 988 mg/100 g和1 703 mg/100 g。关于低盐饮食,不同职业的消费者在接受低盐饮食的宣传渠道上有差异(χ2=14.20,P=0.048),消费者教育接受率为41.7%,态度正向选择率为89.50%,行为选择率为56.28%,知识平均知晓率为49.31%。结论随着GB28050-2011《食品安全国家标准-预包装食品营养标签通则》实施,预包装食品的钠含量标示率大幅度增加。然而,消费者的低盐饮食认知程度仍然较低,相关部门还应加强低盐饮食宣传教育。
