AB  - The aim of this study was to determine the content of phytic acid (phytate) in soybeans (Glycine max), yellow shelled peas (Pisum sativum) and lentil (Lens esculenta). Dry seeds were grounded to a fine powder. The moisture of samples was determined according to the Official Journal of the European Union (2009). The moisture of the samples was 8.42% in soybeans, 11.19% in yellow shelled peas and 10.07% in lentil. The content of phytic acid was determined by the modified Holt's method (1955) using the spectrophotometer. Standard curve was measured using the Na phytate standard solution (0.2 mM). The phytate content in G. max varied from 1.28 to 1.86% in dry matter and from 1.17 to 1.70 g per 100 g of the sample. The content of phytate in P. sativum ranged from 0.49 to 0.86% and from 0.43 to 0.77 g per 100 g of the sample. The phytate content in L. esculenta varied from 0.45 to 1.39% in dry matter and from 0.40 to 1.25 g per 100 g of the sample. These obtained values could be influenced by many factors, e.g. climatic conditions, location, variety, etc.
