为了研究刺梨花瓣的营养、保健及利用价值,同时为刺梨花的开发利用提供科学依据,本研究以贵州安龙、龙里、贵定3个地区栽培的‘贵农5号’刺梨花瓣为材料,分析测定其中主要营养及保健成分的含量,对刺梨花瓣的营养保健及利用价值进行了评价。结果表明:在每100g干花瓣中含有Vc622.62mg,VE28.62mg,VB10.16mg,VB20.12mg,VB120.07mg,可溶性总糖22.71g,粗蛋白7.80g,总膳食纤维33.65g,总酚3181.17mg,总黄酮200.06mg,花青素179.97mg。刺梨花瓣中Fe、Zn含量分别达120.33mg/kg和68.86mg/kg。刺梨干花瓣中的蛋白质氨基酸共有18种,其中必需氨基酸9种;游离氨基酸共15种,其中有必需氨基酸7种。刺梨花瓣的VC含量是玫瑰的10.9倍,槐花的4.98倍,金针菜的14.9倍,VE含量是金针菜中2.19倍。按照标准模式进行评价,刺梨花瓣的蛋白质与膳食纤维品质较优。刺梨花瓣中的营养及保健成分丰富,营养价值高,可用于开发营养食品和保健食品。 |
英文摘要: |
To study the nutrition, health care and utilization value of Rosa roxburghii petals, to provide a scientific basis for development and utilization of the flowers of Rosa roxburghii. In this study, the contents of nutrients and healthcare components in R. roxburghii ‘Guinong 5’ petals cultivated in Anlong, Longli, and Guiding districts in Guizhou were determined and analyzed to provide a scientific basis for the development and utilization of R. roxburghii petals. The contents in every 100 g of dried petals had VC, 622.62 mg; VE, 28.62 mg; VB1, 0.16mg; VB2, 0.12 mg; VB12 0.07mg; total soluble sugar, 22.71 g; crude protein, 7.80 g; total dietar?y fiber, 33.65 g; total phenols, 3181.17 mg; total flavonoids, 200.06 mg; and anthocyanins, 179.97 mg. The petals were rich in Fe and Zn elements, whose contents were 120.33 and 68.86 mg/kg, respectively. A total of 18 protein amino acids were found in the dried petals of R. roxburghii, including 9 essential amino acids. In addition, 15 free amino acids were found in the dried petals of R. roxburghii, including 7 essential amino acids. The VC content of the petals of R. roxburghii was 10.9 times that of Rosa rugosa, 4.98 times that of Sophora japonica, and 14.9 times that of Hemerocallis citrina Baroni, while its VE content was 2.19 times that of Hemerocallis citrina Baroni. These petals had complete essential amino acid species, and they satisfied the requirements of high-quality protein. The soluble dietary fiber in these petals accounted for 11.20% of the total dietary fiber, which satisfied the requirements of high-quality dietary fiber. The petals of R. roxburghii had abundant nutrients and healthcare components suitable for the development of nutritious and healthcare foods. |
