The ideal model of FAO/WTO, the amino acid composition of the better quality protein is about 40% EAA/TAA, and EAA/NEAA is more than 60%. It can be seen that several indicators of yam amino acid meet the above requirements. Its umami amino acid (FTAA) content reached 38.25% of amino acid content, which proved that its muscles are rich in amino acids and delicious in taste, which is significantly higher than the nutritional quality of grass carp and carp.
