摘要: 对常山胡柚和葡萄柚的果实外观性状(单果重、果形指数和果皮厚度)、主要营养品质指标(总可溶性固形物、总糖、还原糖、总酸、维生素C、矿物质和氨基酸含量)和功能成分含量(黄酮类物质、柠檬苦素类物质和精油)进行了对比测定和分析研究。研究结果表明:常山胡柚的苦味物质(柚皮苷和柠檬苦素类物质)和总酸含量比葡萄柚低,总糖、总可溶性固形物以及矿物质元素钙、铁、锌和硒含量较高。红肉型葡萄柚中的柚皮苷和柠檬苦素类物质含量比其他品种高,两种葡萄柚的精油含量均比胡柚高。在口感上,葡萄柚比常山胡柚偏苦、偏酸。总体上常山胡柚和葡萄柚都含有丰富的营养物质和功能性成分,具有较高的营养和保健价值。该研究对常山胡柚和葡萄柚的生产和消费具有一定的指导作用。

Abstract: The appearance characteristics (fruit weight, indexes of fruit shape and peel thickness), contents of nutritive ingredients (total soluble solids, total sugars, reducing sugars, total acids, vitamin C, minerals and amino acids) and functional compounds (flavonoids, limonoids and essential oil) of Changshan\|huyou and grapefruit were analyzed and compared. The results showed that the contents of bitter compounds (naringin and limonoids) and total acids in Changshan\|huyou were lower than those in grapefruit, and the contents of total sugars, total soluble solids and minerals (calcium, iron, zinc, selenium) in Changshan\|huyou were higher than those in grapefruit. While contents of naringin and limonoids in red pulp grapefruit were much higher than the others in this study. The essential oil contents in two kinds of grapefruit were higher than those in Changshan\|huyou. The taste of grapefruit was more bitter and sourer than that of Changshan\|huyou. However, both Changshan\|huyou and grapefruit contained abundant nutrient substance and functional compounds, and had high nutrition and healthy value. This study would be a certain guide to the production and consumption of these two kinds of citrus.
