| Abstract: |
| To provide a reference for the development and utilization of seed kernels of Erythropalum scandens, taking the seed kernels of Guichi No.1 and Guichi No.2 as experimental materials, the contents of crude fat, protein, mineral elements, and amino acid composition of the seed kernel, and fatty acid composition of the seed kernel oil, were determined by national standard methods. The rationality of the amino acid composition and content was evaluated, and the safety of the kernel oil was investigated. The nutritional value of Erythropalum scandens seed kernels was comprehensively evaluated. The results showed that the kernel yield of Guichi No.1 and Guichi No.2 seeds were 52.88% and 4940%, respectively. The crude fat content in seed kernels were 50.37% and 48.43%, respectively. The protein content was 17.70% and 18.23%, respectively. There were 16 amino acids in Erythropalum scandens seed kernels, including 7 essential amino acids and the SRC were 6329 and 6385, respectively. The contents of potassium, calcium, magnesium, iron and zinc in seed kernels of Erythropalum scandens were higher, while the content of sodium was lower. The mineral elements were balanced, and the heavy metal content did not exceed the national standard limits. The main fatty acid in the seed kernel oil of Guichi No.1 and Guichi No.2 was oleic acid, with contents of 80.03% and 7008%, respectively. The lead content, benzo(a)pyrene, aflatoxin B1, residucal solvent, as well as the acid value and peroxide value of the two types of Erythropalum scandens seed kernel oil all met the relative national standard limits, indicating a high level of safety. The seed kernel protein of Guichi No.2 has higher nutritional value, while the crude fat and oleic acid contents in the kernel oil of Guichi No.1 are relatively higher, and both have the development and utilization value in health food and oilseed. |
