Abstract

【Objective】Herein, we investigate the nutritional value of palm buds, providing basic reference data for the purification and active exploration of their bioactive functional components and providing the corresponding reference basis for comprehensive exploitation and utilization.【Method】Basic nutritional and functional components of palm buds were characterized and the obtained results were compared with the corresponding data for common edible tree flowers(osmanthus, Sophora japonica).【Result】Fresh palm buds contained protein(0.050 8 g/g), crude fiber(0.011 6 g/g), fat(0.003 7 g/g), vitamin C(0.18 mg/g), and other basic nutrients, along with abundant mineral elements such as calcium and potassium, being rich in 17 kinds of amino acids, including essential(in all proportions was 25.82%)and flavor ones(in all proportions was 38.49%). Moreover, the buds exhibited total phenolic and flavonoid contents of 12.664 and 11.032 mg/g, respectively, additionally containing crude polysaccharides(4.605 mg/g)and other functional ingredients. 【Conclusion】Comparison with other vegetables revealed that palm buds are very rich in nutrients, exhibiting the advantages of high protein and low fat content and being a precious edible forest resource satisfying the requirements of modern health food. Thus, the nutrition healthcare value of palm buds can be further developed to result in wide application prospects.
