Abstract: To analyze the amino acid composition of Morchlla and evaluate its nutritional value, 20 different strains of Morchlla were used. The amino acid was determined by automatic analysis instrument, and amino acid score (AAS), chemical score (CS), essential amino acid index (EAAI) were calculated. The results showed that essential amino acids were abundant in variety, the content of flavor amino acid and medicinal amino acids was rich, and the proportion of fresh sweet amino acids was large. The AAS and CS showed that the first limited amino acid of Morchlla was leucine, lysine, methionine and cystine. The total amino acids were highly correlated with various amino acids, but it was not significant with protein nutritional value. Through cluster analysis, these samples could be divided into 2 categories, one of which was high-quality protein, and the other was poorly-nutrient. The results provided a good theoretical reference for the breeding and product development.
