| The national standard method was used to determine the main nutritional ingredients of Juglans regia L.f. luodianense Liu et Xu, such as fatty acids, amino acids and minerals, and its fruit characteristics. The results showed that the nutritional ingredients of Juglans regia L.f. luodianense Liu et Xu kernel was dominated by the fat content(56.57%), and Ca(1.27 mg/g), Zn(0.027 2 mg/g) and protein(16.84%) were also abundant. The fatty acids of the kernel were mainly unsaturated fatty acids(9083%), and the contents of linoleic acid, oleic acid, linolenic acid and palmitic acid were high, with a total content of 97.12%. The kernel contained 17 amino acids, and the total content was 137.79 mg/g, including eight kinds of essential amino acids, accounting for 31.03% of total amino acids. The average fruit weight of Juglans regia L.f. luodianense Liu et Xu was 8.333 g, and the shell thickness was 1.03 mm, the kernel weight was 4.987 g, and the kernel yield was 59.84%. The comprehensive characters of Juglans regia L.f. luodianense Liu et Xu reached the national grade 1 to excellent quality index value, which was rich in nutrition and suitable for popularization in large areas. |
