Twenty five free amino acids were quantitatively measured in 11 species of fruits. All species analyzed gave free amino acids, some like
asparagine were at abundant and some like methionine and cysteine were at low levels, but each species showed characteristic profiles.
γ-Amino butyric acid, known for its health benefit, was found at significant levels. It is important to evaluate nutritional values of free amino
acids in fruits where amino acid analysis is still a powerful tool. Our analysis should provide valuable data for the establishment of nutritional
databases and also contribute to nutritional surveys including health benefit of amino acids.
