| This paper with the shiny-leaf yellowhorn(Xanthoceras sorbifolia Bunge) for materials, collects and settles the physical and chemical indicators related to the quality of the shiny-leaf yellowhorn from different regions in the literature, and to enrich the shiny-leaf yellowhorn germplasm resources, determines the corresponding index of the shiny-leaf yellowhorn seed from Henan Xingyang, Shanxi Fangshan, Hebei Zhangjiakou, Shanxi Hunyuan, Shandong Weifang as supplement, analyses the recorded data to build the processing quality evaluation system. Main research results of this paper are as follows:Firstly, in the aspect of seed quality feature, this experiment with the the shiny-leaf yellowhorn seed from Henan Xingyang, Shanxi Fangshan, Hebei Zhangjiakou, Shanxi Hunyuan, Shandong Weifang for raw materials, studied the particle size, thousand grain weight,volume- weight, moisture content, ash content, four main minerals(Fe, Zn, Mg, K) content, found that there were significant differences between the related traits, and grain shape and color have no obvious difference with the reported. The moisture content of the shiny-leaf yellowhorn seed from different regions is between 3.72 % and 4.64 %, and ash content is between 1.57 % and 3.76 %. Fe, Zn, Mg, K, the most abundant areas of four kinds of mineral elements content is respectively Shanxi Zhidan, Jilin Baicheng, Henan Lingbao, Henan Xingyang.Secondly, the relationship model building of the quality of the shiny-leaf yellowhorn and oil: the crude fat of the shiny-leaf yellowhorn seed from Zhidan(65.21 %), Chifeng(64.01 %) is higher. The average value of unsaturated fatty acid content in various areas was 78.22 %. The acid value is 0.82 mgKOH/g, peroxide value of 0.50mmol/kg, iodine value of 110.57 gI2/100 g, saponification value of 183.34 mgKOH/g. The correlation analysis of the composition of fatty acids and the content of crude fat from different regions show that the crude fat and oleic acid presents the significantly positive correlation, negative correlation with linoleic acid. Clustering analysis of the shiny-leaf yellowhorn from 15 regions show that Zhidan and Jianpin is the most appropriate region for extractin the shiny-leaf yellowhorn oil, then Fanshan regions, suitable for using as oil plants of the shiny-leaf yellowhorn.. By the discriminant analysis of the shiny-leaf yellowhorn, the discriminant function model is established to discriminant out the basic unknown shiny-leaf yellowhorn breed suitable for using as oil plants in industrial production.Thirdly, the relationship model building of the quality of the shiny-leaf yellowhorn and protein: the content of crude protein(35.16 %) and essential amino acid(11.09 g/100 g) of the shiny-leaf yellowhorn in Shanxi Fangshan is the highest. The isoelectric point of the shiny-leaf yellowhorn protein is 4.6,and has better properties of hold water, oil absorption and solubility. The correlation analysis of the content of amino acid and crude protein from different regions shows that crude protein and alanine are significantly positively related. Clustering analysis of the shiny-leaf yellowhorn presents that Fanshan is relatively appropriate for the processing of the shiny-leaf yellowhorn protein products, then Xingyang, Hunyuan, Zhangjiakou, Weifan, Chifeng, Yangling, Baicheng, Xian, Yinchuan, Wengniu, is relatively fit for processing protein products. By the discriminant analysis of the shiny-leaf yellowhorn, the discriminant function model is established to discriminant out the basic unknown shiny-leaf yellowhorn breed suitable for processing protein products in industrial production.Lastly, the study of total number of colonies of the shiny-leaf yellowhorn shell and kernel from Xingyang, Fangshan, Zhangjiakou, Hunyuan and Weifang found that the shell has more mould and few yeast, which are the common bacteria in the environment, not find the pathogens, seeds did not find any colony; The detection of aflatoxin B1, B2, G1, G2 for five regions show that the results are negative. |
