Abstract

Limited data are available on the content of inositol phosphates in feed ingredients. The doubtfulness over the identity and literature values of the inositol hexaphosphate (phytate) analysed in feed ingredients by the classical iron precipitation method prompted the analysis for inositol phosphates in some feed ingredients using a modified high-performance liquid chromatography method. The inositol phosphates analysed were inositol triphosphate (IP3), inositol tetraphosphate (IP4), inositol pentaphosphate (IP5) and inositol hexaphosphate (IP6). At least 97% of the inositol phosphates in grains occurred as IP6 and the remainder as IP5. In milled products the relative percentage of IP5 was higher (up to 14.5% in wheat bran) but the overall IP6 relative percentage was still high (more than 82%). IP3 and IP4 were not present in grains, and their amounts were very low when present in their milling orprocessed fractions. The absolute IP6 content was highest in rice bran and wheat bran at 68.31 and 47.63 g kg(-1), respectively. The results indicate that processed plant products may contain hydrolysis products of IP5 and IP6. These products contain greater percentages of IP3, IP4 and IP5 than in grains or milling products.
