Sodium, lead and cadmium contents in samples of processed agricultural products
were evaluated by inductively coupled plasma-optical emission spectrometry(ICP-OES)
after dry ashing procedure. This study was examined for 44 Cereal processed
products(cereal flours), 5 Soybean processed products(bean flours), 4 Starch processed
products(sweet potato flours), and 14 Other processed products(bread crumps). There was
a wide variation in sodium contents with the highest level in a Other processed
products(bread crumps) sample of 1,144.3 mg per 100 g. On the other hand, the
maximum level of lead and cadmium contents was found to be 0.083 and 0.014 mg/kg,
much less than the standard(less than 0.2 mg/kg) demanded for the registration of a very
similar product as wheat flour. This data will provide useful information to make a
regulatory plan on these products.
