Authors investigated on the content of tin metals in 108 samples of tinplated canned fruit commercial. 1. The highest concentration of tin in 11 kinds of samples of canned fruit that is, apricot nectar was 114ppm and lowest of that 2.5∼3ppm. 2. There was 48.6ppm of tin content in orange nectar A that of pineapple nectar 56.6ppm in higher remarkably and that of the other samples was no appearance difference. 3. There was 114ppm(number 10), 5.3∼56.6ppm(number 8) and 8.7∼48.6ppm(number 3) of tin content in minimum between maximum concentration for difference remarkably and that of others there was no difference considerably, The highest concentration in detection frequency of content range was 8∼ 14ppm in 41. 7% and 2.5"6.6ppm in 36.1% and that of concentration was lower for comparison the others. 5. There was lower contration of tin in all samples for law of food hygiene in limitation 150ppm.
