摘要
对市售德庆贡柑的营养成分如水分、灰分、总糖、还原糖、总酸、果胶、蛋白质、脂肪、粗纤维、维生素C和矿质元素(Cu、Zn、Mn、Fe)进行了分析测定,并与江西脐橙进行了比较。结果表明,贡柑和脐橙各成分含量相差不太大,但贡柑中的水分含量比脐橙高,而粗纤维约为脐橙的一半,糖酸比则约是脐橙的两倍,贡柑与脐橙的VC以及Fe、Cu、Zn等矿质元素含量都较丰富。
The main nutrient component such as water, ash, total sugar, reducing sugar, total acid, pectin, protein, fat,crude fiber,Vc and mineral elements such as Cu,Zn,Mn and Fe in Gonggan were analyzed and compared with those in navel orange.The result showed that the nutrient ingredients were similar in these two citrus fruit, but the water in Gonggan was higher than that in navel orange,the crude fiber in Gonggan was about half of that in navel orange,and the sugar acid ratio of Gonggan was about two times of that in navel orange.Gonggan and navel orange were both rich in Vc and mineral elements such as Cu,Zn and Fe.
