this study was carried out to determine the effect of fermentation, hydrothermal treatment, soda (na2co3), and table salt (nacl) addition on the extent of phytase activity and phytate degradation in three iranian wheat cultivars, namely, mahdavi, ghods, and roshan. the samples were milled to three different extraction rates, i.e. whole, 85%, and 75% flours and three kinds of leavening procedure...

Abstract We aimed to investigate phosphorus (P) mobilization by different plant species from organic and inorganic sources in relation P mechanisms. Knowledge about is important for producing crops on other than phosphate rock-derived fertilizers. conducted a greenhouse experiment with four (maize, soy, lupin, mustard) three (FePO 4 , phytate, struvite). determined pH phosphomonoesterase activi...

Besides the inorganic constituents, phytate was also determined in the dry material, and was found to contain an initial level of 1.4±0.2 mg/g [3]. The storage stability of this constituent is being investigated. This preliminary investigation has demonstrated the feasibility of exploring a total mixed diet matrix for certification as a multicomponent Standard Reference Material (SRM). A bigger...

Eight mature dogs (19.3 +/- 0.1 kg) were used in an experiment to compare the effects of feeding soybeans containing low concentrations of oligosaccharides and phytate on nutrient availability in complete foods fed to dogs. All foods were formulated to be isonitrogenous and contained low-oligosaccharide, low-phytate soybean meal (LLM); conventional soybean meal (SBM); low-oligosaccharide, low-p...

The residual activities of transgenic corn-derived and 2 commercial microbial phytases (PA and PB) along the gastrointestinal tract (GIT) of laying hens were compared to evaluate their relative resistance to hydrolysis in the GIT when added to P-deficient diets. The treatments consisted of a negative control (NC) diet containing 0.10 nonphytate P and an NC diet supplemented with transgenic corn...

Plant-based complementary foods often contain high levels of phytate, a potent inhibitor of iron, zinc, and calcium absorption. This review summarizes the concentrations of phytate (as hexa- and penta-inositol phosphate), iron, zinc, and calcium and the corresponding phytate:mineral molar ratios in 26 indigenous and 27 commercially processed plant-based complementary foods sold in low-income co...
