| 摘 要： | 采用国家规定的标准方法,分别测定了脆嫩-厚成期(1~5月份)荣成地区养殖海带体内9种物质(蛋白、脂肪、粗纤维、粗灰分、碘、磷、钙、铁和锌)含量,系统分析了各物质成分含量变化规律,以及各成分与海水温度的关联性。分析表明,不同物质质量分数最高值出现时间不同,其中蛋白质和粗灰分质量分数最高值出现在1月份,脂肪、磷和锌出现在2月份,碘和铁出现在3月份,粗纤维和钙出现在5月份。同时,1~5月份各种物质质量分数变化规律也不相同,蛋白质、粗灰分、磷和锌的质量分数呈现下降趋势,粗纤维、钙的质量分数呈上升趋势,而碘和铁的质量分数变化不稳定。蛋白质、脂肪、粗纤维、粗灰分、磷和锌含量变化与温度有显著关联性。

Analysis of component changes of Saccharina japonica at mushroom-adult stage |
| |
| Abstract: | Using national standard methods, nine components (protein, fat, crude fiber, crude ash, iodine, phosphorus, calcium, iron and zinc) of Saccharina japonica at its mushroom-adult stage (from January to May) cultivated in Rongcheng were measured. The change regularity of different compositions and the correlation between each composition and the sea temperature were systematically analyzed. The results indicated that there were significant differences in the maximum value appearing time of each component. The maximum value of protein and crude ash appeared in January, fat, P and Zn appeared in February, I and Fe appeared in March, and crude fiber and Ca appeared in May. Their variety laws were also different. The values of protein, crude ash, P and Zn showed a decling trend, the values of crude fiber and Ca showed a increasing trend; while the trends of I and Fe were irregular. The content changes of protein, fat, crude fiber, crude ash, P and Zn had significant correlation with sea temperature. |
