We conducted this analysis to make consumers have useful information about consumed foods on the market by investigating the additives contained in food. Korean food additive code (2007) allowed 634 kinds of food additives to be used in domestic products. The food additives consisted of 426 kinds of synthetic additives, 201 kinds of natural additives and 7 kinds of mixture additives. We purchased total 117 kinds of samples; 94 items including sorts of nuts, vegetables and dried fishery products from local markets and discount marts, and 23 kinds of traditional liquors from March to November, 2007, and we researched for various food additives like artificial sweetener, tar pigments and sulfur dioxide. We detected 11.5 to 4,452.3 mg/kg of sulfur dioxide in 18 out of 94 samples except liquors, finding out some artificial sweetener of sodium saccharin in 2 out of 23 liquors, however, no tar pigments were detected from all of the samples. We found out that 2 cases of shredded jujube from china (2476.6 and 4,452.3 mg/kg) proved to exceed regulatory guidance (2000 mg/kg) in sulfur dioxide. Also, we found out that one dried cherry tomato from china contained 88.9 mg/kg and one domestic dried pumpkin 1653.7 mg/kg of sulfur dioxide which should not be detected in vegetables.
