Abstract

Pyropia yezoensis were sampled from Jeonnam in Korea, Jiansu in China and Saga in Japan. Sampled P. yezoensis were analyzed proximate composition by Association official Analytical Chemists(AOAC) method, minerals by ICP-OES and amino acid by amino acid analyzer. Three areas resulted that contents of moisture and crude protein were $8.13{\pm}0.38%$ and $37.25{\pm}1.15%$, and crude lipid, ash and carbohydrate were $2.12{\pm}0.27%$, $7.41{\pm}0.36%$ and $45.06{\pm}1.30%$ respectively. In total minerals, Korea and China were $28300.19{\pm}76.39ppm$and $13945.63{\pm}7.73ppm$, and Japan was $12262.485{\pm}4.38ppm$. Amino acids, Korea and China were $265.28{\pm}0.38mg\;g^{-1}$ and $209.19{\pm}0.19mg\;g^{-1}$, and Japan was $157.61{\pm}0.43mg\;g^{-1}$. Therefore, those substance contents of P. yezoensis are significantly different between cultivation sites. The basic data may used to the environmental and nutritional study of P. yezoensis based on country sites.

본 연구는 지역별로 생산되는 김의 일반성분, 무기질, 아미노산 성분함량 측정하여 비교분석하고자 하였다. 지역구분은 한국의 전남, 중국의 강소성, 일본 아리아케 지역에서 생산되는 방사무늬김(Pyropia yezoensis)을 대상으로 일반성분은 AOAC 방법으로 분석하였으며, 무기물은 ICP-분광분석기, 아미노산은 아미노산 분석기로 정량정성 분석하였다. 분석 결과 한국, 중국, 일본의 일반성분 함량의 범위에서 수분은 $8.13{\pm}0.38%$ 조단백은 $37.25{\pm}1.15%$ 조지방은 $2.12{\pm}0.27%$ 회분은 $7.41{\pm}0.36%$ 탄수화물 $45.06{\pm}1.30%$을 확인하였고, 총 무기질 함량은 한국 $28300.19{\pm}76.39ppm$, 중국 $13945.63{\pm}7.73ppm$, 일본 $12262.485{\pm}4.38ppm$으로 한국이 가장 높았으며, 총 아미노산의 경우 한국 $265.28{\pm}0.38mg\;g^{-1}$, 중국 $209.19{\pm}0.19mg\;g^{-1}$, 일본 $157.61{\pm}0.43mg\;g^{-1}$으로 나타났다. 원산지별 연안생태환경에 따라 일반성분 및 무기질, 아미노산 함량의 차이가 나타나는 것을 확인할 수 있었으며 향후 다양한 국가에서 생산되는 김에 대한 연구 기초자료로 활용될 수 있다고 사료된다.
