Abstract

African palmyra palm (Borassus aethiopum) grows widely across Africa. Previous studies indicated its fruit flour has a great potential in food applications. The objective of this work was to investigate the effect of different drying methods on the mineral composition, antioxidant properties, anti-nutrient composition and phytochemical composition of the African palmyra palm (APP) flour. The fresh fruit pulp was obtained, freeze dried, oven dried, solar dried and milled into flour. Phytochemical screening, mineral analysis, anti-nutrient analysis and antioxidant analysis were conducted on the flour obtained according to standard methods. The flour had high total phenols (1518.00 - 3896.71 mg GAE/100g), potassium (237.00 - 276.73 mg/100g), magnesium (211.61 - 293.62 mg/100g) and saponin (36.10 – 55.62 g/100g). The flour samples also had considerable free radical scavenging activities. Phytochemical screening indicated the presence of several phytochemicals including glycosides. Drying had a significant effect on the analysed composition of APP flour.

非洲棕榈果粉的矿物成分、抗氧化性能、植物化学和抗营养成分

非洲棕榈(Borassus aethiopum)在非洲广泛生长。以往的研究表明，其果粉在食品方面具有很大的应用潜力。研究了不同干燥方法对非洲棕榈(APP)面粉矿物成分、抗氧化性能、抗营养成分和植物化学成分的影响。新鲜果肉经冷冻干燥、烘箱干燥、日光干燥和碾磨成面粉。根据标准方法对所得面粉进行植物化学筛选、矿物质分析、抗营养分析和抗氧化分析。其中总酚(1518.00 ~ 3896.71 mg GAE/100g)、钾(237.00 ~ 276.73 mg/100g)、镁(211.61 ~ 293.62 mg/100g)、皂苷(36.10 ~ 55.62 g/100g)含量较高。面粉样品还具有相当的自由基清除活性。植物化学筛选表明存在几种植物化学物质，包括糖苷。干燥对APP粉的成分分析有显著影响。
