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。
Using national standard methods, nine components （protein, fat, crude fiber, crude ash, iodine, phosphorus, calcium, iron and zinc） ofSaccharina 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 compo-sition and the sea temperature were systematically analyzed. The results indicated that there were significant differ-ences in the maximum value appearing time of each component. The maximum value of protein and crude ash ap-peared 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.
