SummaryThe amino acids in seven Australian honeys were investigated qualitatively and quantitatively using an automatic amino acid analyser; 17 were separated, identified and measured quantitatively. In general the same amino acids were found in all the honeys (7Eucalyptus, 1Trifolium), but the amounts of the different acids varied greatly, and there were important differences between species. The probable origins of the amino acids in honey are discussed.
