摘要
为探索百合花瓣中营养成分价值,开发花瓣的食用价值并选育品质较高的种/品种。选择14种/品种百合花瓣为实验材料,检测了其中营养成分、活性物质、矿物质元素和氨基酸的含量,并参照文献与传统食用百合鳞茎作比较。同时采用主成分分析和聚类分析方法开展品质筛选和综合评价研究。结果表明,百合花瓣中含有丰富的碳水化合物、蛋白质及矿物质元素。将测定的16个营养指标进行主成分分析后提取出6个主成分,累计方差贡献率为86.085%。评价结果显示,卷丹、‘耀眼’、紫脊百合、‘函数’、‘艾迪沃’营养品质得分较高。对14种/品种百合进行聚类分析,划分为4大类,并结合主成分分析结果发现,卷丹综合品质最高。通过建立百合综合评价体系,为开发利用药食兼用百合花瓣、丰富植物源健康食品和建立百合精深加工技术提供理论依据。
In order to investigate both the nutritional and edible value of lily petals and select the high-nutrition lily species or cultivars,the basic nutrients of 14 species or cultivars of lily petals were probed. This paper not only detected the nutritive components,active substance,mineral elements and amino acid composition of 14 varieties and compared the results with those of traditional edible lily bulbs referring to relevant literature,but also analyzed the results by using principal component analysis and cluster analysis to develop quality screening and comprehensive evaluation research. The results demonstrated that lily petals were rich in carbohydrate,protein and mineral elements. The principal component analysis of 16 nutrient indicators were carried out,and the cumulative contribution of the 6 principal components was 86.085%. Based on the scores of 14 species or cultivars of lily petal,the top 5 members were ‘L.lancifolium’,the Longiflorum×Asiatic hybrids ‘Dazzle’,L.leucanthum var.centifolium,the Longiflorum×Asiatic hybrids ‘signum’,the Longiflorum×Asiatic hybrids ‘El divo’. Fourteen lily petals were divided into four categories through cluster analysis,according to the result of principal component analysis,‘L. lancifolium’had comprehensive high quality.In conclusion,this research could provide a theoretical basis for the development and utilization of the germplasm resources of lily petal,diversifying crops producing healthy food and initiating intensive processing of whole crop lily.
