Amino Acid Composition and Nutrition Alaysis of Plum Fruits in Fujian Province

Abstract:

In order to understand the nutrition value of plum (Prunus salicina) fruits from Fujian, the contents and composition of amino acids were determined by amino acid analyzer. The results showed that there were 18 protein amino acids and 3 non-protein amino acids in plum fruits. Taurine and protein amino acid contents in ‘Tianhuang’ plum fruits were the highest, accounting for 26.54 mg (100 g)^-1 and 496.14 mg (100 g)^-1, respectively. The contents of ornithine, medicinal amino acid, sour amino acid in ‘American Plums Queen’ were the highest, accounting for 0.36 mg (100 g)^-1, 364.67 mg (100 g)^-1, and 298.28 mg (100 g)^-1, respectively. The proportion of protein amino acid with special efficiency in ‘American Plums Queen’ was the highest for 73.45%. The γ-aminobutyric acid content was the highest in ‘Early Rounge’ plum fruits for 7.98 mg (100 g)^-1. The branched chain amino acid content in ‘Big Rounge’ was the highest for 46.77 mg (100 g)^-1. Therefore, the plum fruits contain all the amino acids, and the contents of amino acids are different. So plum fruits have great value in use.
