| 内容記述 | The trace lithium content of infant formulas was determined by flame photometry using the atomic absorption spectrophotometer with air-acetylene flame, after the decomposition of a sample with nitric-perchloric acid mixture. Infant formulas were divided into five groups; cow's milk-based, goat-based, soy-based, special use (for allergy or diarrhea infants) formulas and milk-powder for cuisine; collected from seven countries of Japan, Korea, USA, Belgium, Spain, Canada and New Zealand. There was no variation in the lithium content of any formulas with four seasons during two years in New Zealand. In cow's milk-based YIF (young infant formulas) lithium content was an almost same level 138ng/g as a mean in the range of 116〜159ng/g regardless of the country manufactured. The lithium content was apparently higher in FUF (follow-up formulas) than in YIF; 172 vs. 116ng/g in Japan, 174 vs. 132ng/g in Korea, 213 vs. 147 in USA. Same tendency was found in the different materials of goat-based formulas 243 vs. 176ng/g and soybased formulas 151 vs. 127ng/g in New Zealand. Daily dietary lithium intake fed on formulas was calculated to be 16μg/day for YIF and 21μg/day for FUF compared with 5〜7μg/day of that on human milk. On the other hand, origin of the lithium in formulas was analyzed to be depending on the impurities of their inorganic chemicals fortified to the formulas, from the constant ratio 3×10^<-5> between lithium and calcium and from the same ratio value of chemicals. | |||||
