Amino Acid Composition and Nutritional Evaluation of Semen Euryales from Different Regions

doi:10.7506/spkx1002-6630-201115053

Abstract

Abstract: The amino acid composition and nutritional evaluation of Semen Euryales harvested from 15 regions were analyzed using an automatic amino acid analyzer. The results showed the average content of total amino acids in 15 samples of Semen Euryales investigated was 103.33 mg/g, and of free amino acids 0.98 mg/g. All of these samples contained all kinds of essential amino acids in a balanced proportion, which was close to the recommended level by WHO/FAO. Among the essential amino acids found in Semen Euryales, the first limited amino acid was Lys. In addition, Glu and Leu were the principal amino acids. However, 15 different geographic origins differed obviously in the contents of Glu and Leu and could therefore be grouped into 5 categories. Further, the nutritional value of southern Euryale ferox grown in the Taihu Lake region of Jiangsu Province, China was not superior to northern Euryale ferox grown in Hongzehu Lake region of the same province in terms of the amino acid composition.

Key words: Semen Euryales, amino acid composition, nutritional evaluation
