The study investigated the seasonal and regional changes in the food components of raw laver Pyropia sp.. Samples
were obtained monthly from December 2017 to March 2018 at auction markets located in Gangseo-gu, Busan (Nakdong-
raw laver), Seocheon-gun, Chungnam, Wando-gun, Jeonnam and Goheung-gun, Jeonnam. The general components,
heavy metals and minerals, free amino acids, total phenolic compounds (TPC), and antioxidant activities
of the samples were analyzed. No significant physicochemical changes in the moisture, crude lipid, and ash contents
were observed in the raw lavers tested. However, the crude protein content of Nakdong-raw laver was the highest
in December 2017 at 7.20±0.28% and the content was higher seasonally and regionally than those of the other raw
lavers. In addition, the taurine, zinc, manganese and TPC contents of Nakdong-raw laver was higher seasonally and
regionally than those of the other raw lavers. The ethanolic extract of Nakdong-raw laver also had higher antioxidant
activity, including as DPPH (2,2'-diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis [3-ethylbenzothiazoline-
6-sulphonic acid]) radical scavenging activity, although there was no significant correlation between TPC and the
antioxidant activity. This study is the first analysis of seasonal and regional changes in the major food components of
raw laver cultivated in Korea.
