| Research Abstract |
Live and frozen short-neck clams stored at -20℃ for 2 weeks were cooked in boiling water, and the extractive components of each hot-water extract and cooked soft parts were examined. The levels of total free amino acids and succinic acid in the hot-water extracts prepared from the live and frozen samples were not significantly different, whereas the levels of adenosine 5'-monophosphate (AMP), inosine 5'-monophosphate (IMP) and inosine in the extract of the frozen samples were higher than those from the live samples. A sensory evaluation revealed that the extract of frozen samples was stronger in umami and overall preference than that of the live samples. Live short-neck clams and freshwater clams were cooked in water, and minerals of each hot-water extract and cooked soft parts were examined. The rate eluted into hot-water extracts from short-neck clams were more than 75% for Na, K, and Ca, while it was less than 60% for Mg and Fe. The elution rates of Na, K, Ca, Mg, and Fe in hot-water extracts from freshwater clams were 96%, 86%, 89%, 84%, and 66%, respectively.
