| 中文摘要: |
| 为探究不同种类柑橘果实的氨基酸组成、含量及营养品质,以尤力克柠檬、纽荷尔脐橙、梁平柚和红橘果实可食部为研究对象,采用柱前衍生-反相高效液相色谱法(RP-HPLC)和外标法对柑橘果实中氨基酸进行定性定量分析。从多样度、匹配度和平衡度等方面对不同种类柑橘果实的营养价值进行系统、全面的评价。研究表明,在尤力克柠檬、纽荷尔脐橙、梁平柚和红橘果实可食部中均检测到17种氨基酸,种类齐全,其中以尤力克柠檬氨基酸总量最高(333.11±17.69 mg/100g),富含天冬氨酸、脯氨酸和谷氨酸。对于不同种类柑橘,以WHO/FAO推荐的不同年龄段中国居民必需氨基酸每日平均需要量为参照进行评价可知,尤力克柠檬所含氨基酸含量更符合人体需求,即具有更高的营养价值。 |

| In order to explore the amino acid composition,content and nutrient quality of different citrus fruits, this study was conducted using Eureka lemon, Newhall navel orange, Liangping pummelo and Tangerine as the research material. The pre-column derivatization-reversed-phase high performance liquid Chromatography(RP-HPLC)and external standard method were used to quantitatively analyze the amino acids in citrus fruits. The nutritional quality of the amino acids in the edible part of different citrus fruits was evaluated by the degree of diversity(DD), degree of match(DM) and degree of balance(DB). The results showed that there were 17 kinds of amino acids detected in the edible part of Eureka lemon, Newhall navel orange, Liangping pummelo and Tangerine, with the highest total content in Eureka lemon (333.11±17.69 mg/100g). Besides,they were rich in Asp(aspartic acid), Pro(proline) and Glu(glutamic acid). For different species of citrus fruits, using the estimated average requirement of essential amino acid(EAA)recommended by the World Health Organization/Food and Agriculture Organization of the United Nations (WHO/FAO) as an appraisal criterion, it was found that the amino acids contained in Eureka lemon was more in line with human needs, i.e., it had higher nutritional value. |
