Current prune composition data are outdated and require a comprehensive and comparative re-analysis. This novel study aimed to: (i) analyse and compare prune composition from major countries of origin; and (ii) provide a comprehensive compositional analysis of prunes of USA origin and compare this with UK and USA database data. Prune samples were analysed for major nutrients and bioactive compounds and compared between countries of origin. Total fibre was higher in prunes from the USA (12.0 g/100 g) and Chile (11.5 g/100 g) compared with France (8.4 g/100 g) and Argentina (8.9 g/100 g), while prunes from all countries contained high levels of sorbitol (11.2-15.5 g/100 g). Differences in energy and starch values compared with national databases reflected different approaches to sampling and analysis. In conclusion, prunes contain high levels of fibre and other bioactive compounds. Variations between country of origin and database values highlight the importance of transparency in documenting sampling and analysis methods.
目前的李子干成分数据已经过时,需要进行全面和比较的重新分析。本研究旨在:(i)分析和比较主要原产国的李子干成分;(ii)对美国产李子干进行全面的成分分析,并与英国和美国数据库数据进行比较。对李子干样品进行了主要营养成分和生物活性化合物的分析,并比较了原产国之间的差异。与法国(8.4g/100g)和阿根廷(8.9g/100g)相比,美国(12.0g/100g)和智利(11.5g/100g)的李子干总膳食纤维含量更高,而所有国家的李子干都含有较高水平的山梨糖醇(11.2-15.5g/100g)。与国家数据库相比,能量和淀粉值的差异反映了采样和分析方法的不同。结论:李子干含有高水平的纤维和其他生物活性化合物。原产国和数据库值之间的差异突出了记录采样和分析方法透明度的重要性。
