| Abstract: |
| In order to develop and utilize the Gnetum seed kernel rationally, the morphology and nutritional quality indexes of seed kernels of Gnetum pendulum and Gnetum parvifolium from Yunnan province were analyzed and evaluated, and the correlation of 60 nutritional quality indexes including basic nutritional components, amino acids, fatty acids and mineral elements were analyzed. The results showed that the length, width, ratio of length to width and 1 000-grain weight of Gnetum pendulum seed kernel were higher, which were 1.78, 1.58, 1.12 times and 4.15 times as many as Gnetum parvifolium seed kernel. The contents of crude protein (13.53%), soluble sugar (6.25%), total flavone (1.09%), γ-aminobutyric acid (1.98 mg/g), Ca (607.30 mg/kg), Mn (46.44 mg/kg), Ni (5.48 mg/kg) and the relative content of stearic acid (25.42%), α-linolenic acid (1.49%), γ-linolenic acid (2.63%) of Gnetum pendulum seed kernel were significantly higher than those of Gnetum parvifolium seed kernel (p<0.01). The contents of dry matter (59.56%), starch (53.49%), crude fat (2.48%), crude fiber (2.50%), P (2 812.73 mg/kg), Mg (1 619.95 mg/kg), Na (8.41 mg/kg), Zn (11.87 mg/kg), Sr(2.26 mg/kg), and 10 amino acids including leucine (15.13 mg/g) and the relative contents of arachidic acid (1.78%) and oleic acid (17.41%) of Gnetum parvifolium seed kernel were significantly higher than those of Gnetum pendulum seed kernel (p<0.01). Correlation analysis results showed that about 40% of the indexes were strongly correlated. In conclusion, the morphology and nutritional quality indexes in the two kinds of Gnetum seed kernels are obvious differences, and they have different nutritional characteristics. |
