This study was conducted to compare the nutritional characteristics of Pyropia tenera with those of P. yezoensis, the predominantly cultivated species in Korea. The proximate composition, mineral content, total amino acids, and free amino acids were analyzed. The results showed that P. tenera had higher crude protein content and lower crude fat content than P. yezoensis. In terms of mineral composition, P. tenera had higher levels of most minerals, including calcium, magnesium, iron, and zinc. Furthermore, essential amino acids, such as leucine, lysine, and valine, as well as free amino acids associated with umami and sweetness, such as glutamic acid, glycine, and alanine, were more abundant in P. tenera. These findings indicate that P. tenera possesses superior nutritional and functional properties, suggesting its potential for reintroduction into aquaculture and development as a high value-added strain. This study provides fundamental data for the future breeding and industrial utilization of P. tenera.
