Abstract：
Phytate is widely distributed in the plant kingdom, and its significance for human nutrition has been often described. Data on phytate is available in very few composition tables, for a limited number of foods and mainly for raw products. With the aim of publishing the first global repository of analytical data on phytate, data on moisture, phytate, zinc, iron and calcium were compiled. Other aspects, such as the analytical method used, biodiversity and processing, were considered, and phytate: mineral ratios were calculated when possible. From a comprehensive literature search, over 250 references were compiled, generating 3377 entries: 39% for raw and 61% for processed foods. Most of the entries were for cereals (35%), followed by legumes (27%) and vegetables (11%). The most common analytical methods used were indirect precipitation (26%) and anion exchange (25%), while separate determination of IPs is the most recommended. The database can be used as a tool for nutrition workers to include into food composition tables and to develop programmes related to mineral deficiencies. These data will be useful for designing diets with enhanced mineral bioavailability and for improving the estimates for nutrient requirements. The database is available at the INFOODS (www.fao.org/infoods/infoods/tables-and-databases/en) and IZiNCG webpages (www.izincg.org).
摘要：
植酸盐广泛分布于植物界,它对人类营养的重要性经常被描述。关于植酸的数据在很少的成分表中可用，用于有限数量的食品，主要用于生产品。为了发布第一个全球phytate分析数据存储库，湿度数据，植酸,锌，铁和钙被编译。其他方面,例如使用的分析方法，生物多样性和加工，被考虑,和植酸盐：矿物质比例在可能的情况下进行计算。从全面的文献检索中，编译了250多篇参考文献，产生3377个条目：生食品占39%，加工食品占61%。大多数条目是谷物（35％），其次是豆类(27%)和蔬菜(11%)。最常用的分析方法是间接沉淀(26%)和阴离子交换(25%)。而单独确定IP是最推荐的。该数据库可用作营养工作者的工具，可将其纳入食物组成表，并制定与矿物质缺乏有关的计划。这些数据将有助于设计具有增强矿物质生物利用度的饮食，并改善对营养需求的估计。该数据库可在INFOODS（www。fao.org/infoods/infoods/tables-and-databases/en)andIZiNCGwebpages(www.izincg.org)。
