宽礁膜营养成分分析及营养学评价

Analysis and evaluation of nutrient components of Monostrom latissimum

摘要:

人工栽培的宽礁膜的蛋白质、总氨基酸和游离氨基酸含量分别占干重的23.13%、19.95%和1.27%，脂肪含量为2.64%，基中不饱和脂肪酸占脂肪酸含量的50.25%。光合色素中叶绿素a、叶绿素b和类胡萝卜素的含量分别为250.46mg/100g、479.75mg/100g和78.63mg/100g。通过与海带和紫菜进行营养学评价，结果表明，宽礁膜中必需氨基酸的化学评分为91分，可作为保健品和药物的优质原料。

Abstract:

The nutrient components of Monostrom latissimum, which was cultivated in China, were measured and analyzed in this paper. The result indicated that the content of protein, total amino acid and free amino acid in dried thallus was 23.1, 19.95 and 1.27% respectively. The fat content was 2.64%, in which polyunsaturated fatty acid reached 50.25%. The content of chlorophyll a, chlorophyll b, carotenoids accounted for 250.46, 479.75, and 78.63mg/100g dried wt respectively. Compared with laminaria and porphyra to evaluate in nutriology,the results showed the chemical scores of essential amino acid were ninety one for M. latissimum that can probably be used as good raw material of health food and marine drug.
