Abstract
Human beings and animals require food to carry out essential functions, which include growth, development and reproduction. The amino acid content of fruit and fruit-derived foods is studied intensely because of the contribution to nutritional value, aroma, taste and health-promoting effects and their possible use as markers of origin and authenticity. Fruit is a nutrient rich food with a direct connection to public health. Along with several organic compounds, it is now well to cure diseases, but they play important role in many activities in the body. The aim of the study was to monitor the Amino acid profile of five selected ethnic and edible fruits (Annona reticulata, Phyllanthus acidus, Averrhoa bilimbi, Syzygium samarangense and Citrus maxima) as well as investigating the nutritional status of these species in terms of available amino acids. Among all the five selected fruits for their amino acid profiling, the fruit Annona reticulata emerged as the most potential one with higher concentration of all the non-essential amino acids. The highest concentration was shown by the amino acid proline (70.303mg/g), followed by glutamine (66.475mg/g), glycine (63.043 mg/g) and the least one was found to be aspartate (19.594 mg/g). Phyllanthus acidus,was proved to be the next candidate with potential profile of non-essential amino acids, followed by Averrhoa bilimbi, Syzygium samarangense and finally Citrus maxima. All the samples were also analysed for its chemical score to find out the limiting amino acid. In case of Annona reticulata, the highest chemical score was in proline (175757.5) and the lowest score was recorded in aspartate (48985). In the case of Phyllanthus acidus, also, highest chemical score was demonstrated in proline (160605) and the lowest score was recorded in aspartate (44762.5). In almost all the samples, the results followed the same pattern.
