摘要

The high selenium content of the Brazil nut,Bertholletia excelsa,makes this seed a healthy food qualified as an antiradical protector.The studied nut contained 126 ppm of selenium.Selenium was found to be distributed in the nut protein fractions.The water-extracted fraction,which represented 17.7% of the cake protein,was the richest in selenium with 153 ppm.Analysis by HPLC-MS showed that selenium was linked by a covalent bond to two amino acids to form selenomethionine and selenocystine.The selenomethionine represented a little less than 1% of the total amount of methionine.
