| Abstract | In this study, variations in the biochemical composition of two Sargassum fusiforme strains (SF-1 and SF-2) with different vesicle shapes collected during harvest period were analyzed. Compared with several other algae, S. fusiforme (commonly known as Hijiki) can be recommended as a nutritious food for its high levels of minerals, polyunsaturated fatty acids, phlorotannins, fucoidan, and alginate. Comparison of the two strains indicated that there were significant differences between the contents and characteristics of some components. The alginate content of SF-1 (15.46-26.30%) was higher than that of SF-2 (14.97-24.40%), while the alginate with highest molecular weight and viscosity was obtained from SF-2 (3.77 x 10(6) g mol(-1), 226.2 mPa s). The content of fucoidan of SF-2 (5.30-11.60%) was higher than that of SF-1 (6.11-7.87%). On the other hand, the phlorotannin content of SF-1 (17.55-48.91 mg g(-1)) was higher than that of SF-2 (28.28-39.76 mg g(-1)), and a higher purity of fucoxanthin could be obtained from SF-1 (80.59-92.40%) than that from SF-2 (72.50-84.14%). Analysis of fatty acid composition indicated that EPA and alpha-linolenic acidwere more abundant in SF-1, whereas arachidonic acid was more abundant in SF-2. The highest content of various nutrients existed in different strains and different periods. So, strain and the time of harvest can be selected according to the purpose of utilization. |
