碩士 / 國立臺灣海洋大學 / 食品科學系 / 101 / The purpose of this study is to compare the proximate composition and anti-fatigue effect of the extracts of Nannochloropsis oculata cultured by surface sea water (SSW) and deep sea water (DSW). Under the same culture condition, the growth rate and the appearance of N. oculata cultured by different sea water showed insignificant difference. The crude protein and carbohydrate content of N. oculata cultured by DSW were higher than cultured by SSW, on the contrary, the crude fat and ash content higher in SSW cultured extracts than DSW cultured extracts. It showed N. oculata cultured by different sea water had influence on their growth. After the ultrasound treatment, the soluble protein and total sugar content of the extracts of N. oculata cultured by DSW were higher than SSW. However the ash content was vice versa for the different cultured extracts. Both extracts of N. oculata cultured by SSW and DSW did not showed any significant difference in the other mineral content, except for sodium content. The antioxidant capacity of DSW cultured N. oculata extracts were significantly higher than SSW cultured extracts. This may be causing with polysaccharide’s amount and composition, and composition of free amino acid of extract. The results of the animal experiments, showed the lactic acid increment of DSW group were significantly better than the control group. The exhausting time, lactic acid elimination, blood urea nitrogen and liver glycogen content were not significantly different from the treatment group and control group. The anti-fatigue effect of the extracts of N. oculata were not significant. However, in comparison to SSW, DSW had potential benefit for anti-fatigue effect.
