The concentrations of BHA, BHT, propylene glycol, and sodium saccharin in foods sold in Japan were estimated using the results of official inspections by 88 local governments, representing most of Japan, in fiscal year 1994. A total of 27.474 samples, including 1,720 imported foods, were inspected. The detection rates of BHA, BHT, propylene glycol, and sodium saccharin were 12.2%, 2.3%, 36.3%, and 11.2%, respectively. The mean concentrations of these food additives in all samples in which their use is allowed were 1.3%, 1.0%, 13.6%, and 5.0%, respectively, of the legally permitted levels. The estimated daily intakes of these food additives were 0.169, 0.051, 57.1, and 7.26 mg/person, respectively, when calculated based on their mean concentrations in foods obtained in the present study and daily food consumption data. The estimated daily intakes were 0.7%, 0.3%, 4.6%, and 2.9%, respectively, of the acceptable daily intake (ADI). The food that contributed most to the daily intake of BHA was dried fish (70.2% of BHA intake); that of BHT was chewing gum (61.6%); that of propylene glycol was raw noodles (67.3%); and that of sodium saccharin was nonalcoholic beverages (27.0%)
