Objective To study method of GTF abstracted from chromium-rich brewer's yeast, determine content of amino acid in abstract.
Methods Extraction and ultrafilitraction were used to obtain abstact from chromium-rich brewer's yeast.
Results Many kinds of amino acids were determined in abstract. Content of glutamine, glycine and cystine was high (3878, 670, and 424 mg/L)。
Conclusion Concentration abstrated by eutraction and ultrafitration contained lots of amino acids which were the content of GTF.
