中文摘要: 测定小球藻Chlorellasorokiniana C74营养成分，为其综合利用提供依据。结果显示，Chlorella sorokiniana C74含有丰富的营养物质，粗蛋白、多糖、油脂、灰分、粗纤维和色素分别占藻粉干重的20.4%、34.28%、22.16%、12.20%、20.22%和4.50%。脂肪酸分析显示Chlorella sorokiniana C74中含有多种不饱和脂肪酸，其中亚油酸和亚麻酸含量分别为22.73% 和14.87%；氨基酸含量为17.50%，其中必需氨基酸为6.17%，通过必需氨基酸指数评价，说明Chlorella sorokiniana C74是一种优质的蛋白来源；维生素含量丰富，尤其是维生素B1、B3和B6；藻粉含有多种矿物质元素，其中钾、镁、钙、铁和锌5种元素含量较高，重金属铅、汞、砷和镉含量均未超标。
Abstract:Determination of Chlorella sorokiniana C74 nutrients，the results showed that Chlorella sorokiniana C74 contains kinds of nutrients，crude protein，carbohydrates，fat，ash，crude fiber and pigment was accounted for 20.4%，34.28%，22.16%，12.20%，20.22%and 4.50%by algae powder dry weight respectively. Fatty acid analysis showed that algae powder contains a variety of unsaturated fatty acids，and linoleic acid and linolenic acid contents were 22.73%and 14.87%.Contents of amino acid in Chlorella sorokiniana C74 was 17.50%，of which the essential amino acids was 6.17%.Through essential amino acid index evaluation，indicating that Chlorella sorokiniana C74 was an excellent source of protein；Chlorella sorokiniana C74 was rich in vitamins，especially vitamin B1，B3and B6.Algae powder contains a variety of trace mineral elements，and potassium，magnesium，calcium，iron and zinc was higher，the heavy metal lead，mercury，arsenic and cadmium was no more than the national standard.
