| 对奇亚籽的营养成分进行了分析与评价。结果表明：奇亚籽中粗脂肪、粗蛋白质和膳食纤维的含量分别为(34.20±1.31)g/100 g（湿基）、（23.31±0.18）g/100 g（湿基）、（27.71±0.09）g/100 g（湿基），为高脂肪、高蛋白质、高膳食纤维芡欧鼠尾草种子；奇亚籽中18种氨基酸总量为23.10 g/100 g（湿基），其中人体必需氨基酸总量为8.20 g/100 g（湿基），氨基酸含量最高的是谷氨酸（4.08 g/100 g），其次是精氨酸（2.46 g/100 g）和天冬氨酸（2.13 g/100 g），根据氨基酸评分，奇亚籽的限制性氨基酸为赖氨酸，根据化学评分，奇亚籽的第一限制性氨基酸为异亮氨酸，奇亚籽的必需氨基酸指数为87；奇亚籽油中共检出21种脂肪酸，其中不饱和脂肪酸以亚油酸（22.43%）和α-亚麻酸（62.48%）为主；奇亚籽中矿物质含量丰富，Ca含量最高，为829.21 mg/100 g，具有高K（673.48 mg/100 g）低Na（22.37 mg/100 g）的特点。 |
| 英文摘要: |
| The nutritional components in the seed of chia (Salvia hispanica) were analyzed and evaluated. The results showed that the contents of crude fat, crude protein and dietary fiber in chia seed were (34.20±1.31) g/100 g（wet basis）, (23.31±0.18) g/100 g（wet basis）and (27.71±0.09)g/100 g（wet basis）, respectively.Therefore, chia seed had the character of high fat, high protein and high dietary fiber. The contents of total amino acids and essential amino acids in chia seed were 23.10 g/100 g（wet basis）and 8.20 g/100 g（wet basis）, respectively. The content of glutamic acid (4.08 g/100 g) was the highest, followed by arginine (2.46 g/100 g) and aspartic acid (2.13 g/100 g). According to the amino acid score, the restrictive amino acid in chia seed was lysine, while the first limiting amino acid was isoleucine according to the chemistry score, and the essential amino acid index value of chia seed was 87; 21 kinds of fatty acids were detected in chia seed oil, and linoleic acid (22.43%) and α-linolenic acid(62.48%) dominated in unsaturated fatty acids. Chia seed also contained abundant minerals. The content of Ca was the highest, reaching 829.21 mg/100 g.The character of high content of K （673.48 mg/100 g）and low content of Na （22.37 mg/100 g）in chia seed was obvious. |
