Fatty acids, free amino acids and 5 '-nucleotides of dried laver,Hoshi-nori, harvested in different months in Hokkaido and produced underdifferent drying conditions [Japanese]

摘要

Fatty acids, free amino acids and 5'-nucleotides were analyzed on some specimens of dried laver, Hoshi-nori, Porphyra yezoensis, which were harvested at Akkeshi in Hokkaido, supplied from different harvest months and were produced by sun drying at about 6 degrees C and by hot air drying at 38 degrees C. There were some differences in the contents of palmitic and icosapentaenoic acids between the sun and hot air drying Hoshi-nori. The free amino acid content increased with the progress of harvest month, especially in aspartic acid, serine, glutamic acid and alanine. Of the hot air drying Hoshi-nori, aspartic acid and asparagine were high, and serine and glycine were low in their contents comparing to those of the sun drying one. Although 5'-AMP and 5'-GMP were analyzed in the both drying Hoshi-nori, 5'-IMP was detected only in the air drying ones.
