10 1557 The variation in fatty acids composition and content of ten Pyropia yezoensis cultivars during different harvest time periods MA Fei 1 2 LU Qinqin 3 HU Chuanming 3 ZHANG Tao 1 ZHOU Wei 3 LI Jiafu 1 DENG Yinyin 1 ZHU Jianyi 1* 1. Department of Biology and Food Engineering Changshu Institute of Technology Changshu 2. Collge of Life Science Nanjing Normal University Nanjing 3. Institute of Oceanology and Marine Fisheries of Jiangsu Nantong 210046 China 226007 China 215500 China Abstract Ten cultivated strains of Pyropia yezoensis were studied in this research in order to identify the effects of the strain difference and the harvesting time difference on the fatty acid composition and content of P. yezoensis. The results show ed that the fatty acid composition of these ten P. yezonsis samples w as not affected however the content of each fatty acid w as affected and the difference among ten samples w as significant. The saturated fatty acids SFAs were mainly composed of 13 0 16 0 18 0 with 16 0 as the highest component about 20%. The unsaturated fatty acids UFAs included 18 1 n-9 18 2 n-6 18 3 n-3 20 1 n-9 20 2 n-7 20 3 n-7 20 4 n-6 AA 20 5 n-3 EPA and the major componet was EPA about 50%. Samples harvested during the lowest water temperature period February contained the highest total fatty acids and EPA concentration the result indicates that the low water temperature has advantages in accumulating fatty acids especially UFAs of P. yezoenis. P. yezoensis is rich in UFAs especially EPA. The n-6 /n-3 ratios ranged from 4. 9 to 7. 7 during the whole study period and this range is consistent with the recommended diet ratio of WHO /FAO.
