研究了南海绿藻石莼的一般营养成分、蛋白质的氨基酸组成,以及一些无机元素的含量.结果表明,石莼是一种富含蛋白质、纤维素和灰分的海藻.石莼蛋白质全部必需氨基酸的含量占总氨基酸量的41.2%,表明石莼富含必需氨基酸;四种呈味氨基酸含量为41.5%,因此石莼是一种营养且味道较鲜美的海藻.石莼的蛋白质营养价根据第一限制氨基酸价(44.3)评价较低,不过第二限制氨基酸价(88.0)为较高,其他氨基酸价较均匀,缬氨酸价最高.石莼五种矿物质含量均高于其他海藻,以铁、镁含量最为明显,表明石莼矿物质含量极为丰富.

In this paper,the contents of general nutritional compositions,amino acid composition of the protein,and of some inorganic elements of the green alga, Ulva lactuca in the South China Sea were studied. The results demonstrated that Ulva lactuca was is an alga rich in protein,cellulose,and ash. The essential amino acid contents of the protein in Ulva lactuca accounted for 41.2% of the total amino acid content,which indicated the alga was rich in essential amino acids.The contents of four kinds of flavor amino acids accounted for 41.5% of the total amino acid contents,so Ulva lactuca is a nutritional and delicious alga.The protein nutritive value in Ulva lactuca was estimated to be lower from first limit amino acid score (44.3),but to be higher from the second limit amino acid score(88.0),and the other essential amino acid scores were balanced,with the valine score being the highest.The contents of the five mineral elements in Ulva lactuca were higher than those in other algae,and the contents of iron (Fe)and magnesium(Mg)were very obvious,which indicated that the mineral contents of the alga were much richer.
