Abstract: To invest the content of Chromium in edible gelatin of part marets and enterprises n Chaozhou, the
research on the food risk is based on it. The random-in p cted samples were pretreated following the method of
the national standard of china, and determined by atomic absorption spectrometry. The method had good
linearity and the linear range was from 0 m/ to 0.500 mgl and the correlation coefficient was up to. 99 6
The RSD of the test samples ranged from 1.32 to 8.34 %o and the average recoveries of samples were
tween 82. 2. 4 %The investigain ruls indicaed that the qualified rate of edible gelatin was on
40. 7 %. The method by atomic absorption spectrometry was accurate, reliable, convenient, rapid and good
precision; and the chromium content of edible gelatin in Chaozhou exceeded the allowed limit seriously
some proposals are put forward to the relative products monitoring
Key words; chromium; atomic absorption spectrometry; determine; edible gelatin
