| Abstract: | It was found that there were 18 hydrolytic and free amino acids in the refined powder of Amorphophallus konjac and A. albus. Total Contents of 18 hydrolytic amino acids, hydrolytic essential amino acids, 18 free amino acids and free essential amino acids were 2.44%,0.62%,1.10% and 0.33% respectively in the former and 2.01%, 0.56%, 0.41% and 0.13% in the later. Their nutritional guality and other special properties were mainly depended on the content of KGM in the refined powder of Amorphoallus konjac and A. albus . |
