元江干热河谷乳油木果实特性及营养成分分析

Vitellaria paradoxa was an important ecological tree and oil crop in tropical Africa, and its fruit was rich inoil and cocoa butter, which was called the emerald of vegetable oil. However, there have been no reports on theanalysis and assessment of fruit characteristics and nutritional components of V. paradoxa when it was introduced toYuanjiang hot-dry river valleys of China. In this study, in order to large area cultivate and comprehensively develop V.paradoxa, the fruit biological characters and nutritional components of V. paradoxa introduced from Africa toYuanjiang County, Yunnan province were analyzed and evaluated by using field investigation and indoorphytochemical extraction method. The results showed that V. paradoxa were tall and graceful, with larger fruit (22.15g/each) and higher edible rate (61.12 %); The content of dietary fiber in fruit was very high (41.52 g/100 g), and thefat content in seeds was 33.72 g/100 g; Moreover, the contents of K, Ca, Mg, Na, Fe and Zn were 6476.70, 376.47,181.93, 139.20, 3.54 and 1.92 mg/100 g, respectively; The fruit was rich in amino acids, and essential amino acidsaccounted for 29.87 %. More importantly, the fruit size, the contents of dietary fiber, fats, K, Ca and aspartic acid offruits in Yuanjiang dry-hot river valley were significantly higher than those in the original region. The findings not only lay a theoretical basis for artificial planting of V. paradoxa in dry-hot river valley, but also offer a certaintechnical support for the industrialization development and the deep processing of products.
