This study was conducted to confirm amino acids from the filterate of pollen treated by purified enzyme of bee larva gut for improving pollen food. The larva gut enzyme were purified by ammonium sulfate, ethanol and Sephadex gel filtration. The filterate of pollen treated with enzyme purified by ammonium sulfate showed the highest amount of amino acids. The amount of amino acids of the filterate from which the pollen was fermented with natural contaminants is 5.5 times as much as the pollen which was not fermented. The filterate of pollen treated with enzyme of bee larva gut contained eighteen different amino acids as follows: aspartates, glutamate, serine, glycine, histidine, arginine, threonine, alanine, proline, tyrosine, valine, methionine, cysteine, isoleucine, leucine, phenylalanine, lysine and trytophane.
