| 中文摘要: |
| 分析了湘西猕猴桃籽的主要成分，同时采用水酶法提取猕猴桃籽油，并对猕猴桃籽油的特性进行了研究。结果表明：湘西猕猴桃籽粗脂肪含量32.19%，粗蛋白质含量16.06%；猕猴桃籽中氨基酸种类不全，缺少2种氨基酸，属于不完全蛋白质；鲜味谷氨酸（Glu）和天门冬氨酸（Asp）含量很高，分别为6.1 mg/g和3.5 mg/g，占氨基酸总量的25.98％，为猕猴桃籽增添了良好的风味；水酶法提取猕猴桃籽油总出油率为25.89%，萃取率达80.45%；猕猴桃籽油中亚麻酸含量高达60.59%，不饱和脂肪酸含量达89.92%，生育酚含量为812.41 mg/kg。 |

| The main components of Xiangxi kiwifruit seed and the characteristics of kiwifruit seed oil extracted by aqueous enzymatic method were analyzed. The results showed that the crude fat content of Xiangxi kiwifruit seed was 32.19% and the crude protein content was 16.06%. The protein of kiwifruit seed belonged to incomplete protein because of losing two kinds of amino acids, but the contents of glutamate (Glu) and aspartate (Asp) were high, reaching 6.1 mg/g and 3.5 mg/g respectively, accounting for 25.98% of total amino acids, which contributed to a good flavor for kiwifruit seed. The yield and extraction rate of kiwifruit seed oil by aqueous enzymatic method were 25.89% and 80.45%, respectively. There were 60.59% of linolenic acid, 89.92% of unsaturated fatty acids and 812.41 mg/kg of tocopherol in kiwifruit seed oil. |
