不同品种玫瑰果的营养成分比较分析

Analysis of Different Varieties of Rosehips

以西湖二号、平阴五号、大果、北京单瓣红、杂交单瓣红五种玫瑰果为材料,对不同品种玫瑰果所含的营养成分进行了含量测定和分析比较。结果表明,不同品种玫瑰果间营养成分含量存在差异,其中大果中的灰分、粗蛋白、脂肪、黄酮、多酚含量最高,分别为6.67%,4.92%,5.2%,415.71 mg/100 g,512.05 mg/100 g。而西湖二号的含水量最高,达到82.7%,杂交单瓣红的总酸和总糖的含量最高,平阴五号中的维生素C含量最高,可达到591 mg/100 g。另外。玫瑰果中的维生素C和黄酮含量与其他水果相比含量非常丰富。玫瑰果中含有丰富的氨基酸,尤其是人体所必须的赖氨酸,五种玫瑰果中均高于100 mg/100 g。玫瑰果中矿物质种类多,其中钙的含量远远高于其他矿物质元素。

The contents of nutrients contained in different varieties of rose hips were determined and analyzed by using West Lake No.2, Pingyin No.5, Big Fruit, Beijing Single Red, Hybrid single red as materials. The results showed that there were differences between the nutrients contents of different rose hips. The highest content of ash, crude protein, fat, flavonoids and polyphenols is big fruit, which were 6.67%, 4.92%, 5.2% and 415.71 mg/100 g, respectively. The water content of West Lake No. 2 was the highest, reaching 82.7%. The content of total acid and total sugar of Hybrid single red was the highest. The highest content of Vc is Pingyin No.5, reaching 591 mg/100 g. Compared with other fruits. Rose hip is rich in amino acids, especially the lysine which is necessary for human body. The lysine contents in all five rose hips were higher than 100 mg/100 g. There are many types of minerals in rose hips, and the content of calcium is much higher than other mineral elements.
