This study aimed to evaluate the effect of a heat stable phytase derived from Citrobacter braakii on true digestibility of P and on phytate dephosphorylation at the terminal ileum segment in broiler chickens. Four semi-synthetic diets, each containing either wheat, maize, soybean meal or rapeseed meal as the only source of phosphorus and calcium were supplemented with microbial phytase at 1000 ...

During the past decade, the inclusion of microbial phytase in poultry diets has increased remarkably, mainly in response to heightened concerns over phosphorus (P) pollution of the environment. The capacity of this feed enzyme to release phytate-bound P and reduce P excretion is now well documented. Effectively, phytase is an alternative, economical P source and, as global phosphate reserves ar...

OBJECTIVE Although the incidence of urolithiasis is lower in children than in adults, the number of children with urolithiasis is increasing. Phytate, a naturally occurring compound present in legumes, nuts, and whole meals, has antilithiasic activity. The aim of this study was to assess, for the first time, the urinary levels of phytate in children and to correlate these levels with other urin...

BACKGROUND High phytate (HP) consumption is a concern in developing countries because of the high prevalence of iron deficiency in these countries. OBJECTIVE We investigated whether habitual consumption of an HP diet reduces the inhibitory effect of phytate on nonheme-iron absorption. METHODS Thirty-two nonanemic females, 18-35 y of age, with normal body mass index but with suboptimal iron ...

1. A study has been made of the zinc, copper, iron, manganese, protein (nitrogen X 6.25) and phytic acid contents of nineteen soya-bean-based textured-vegetable-protein (TVP) meat-extenders and meat-substitutes and of three "ready-prepared" canned meals containing TVP. 2. Phytate analysis was performed using a newly-developed method based on Holt's (1955) procedure. This method enabled the phyt...

Soybean [Glycine max (L.) Merr.] seed phosphorus is stored primarily as phytic acid, a form in which it is unavailable to monogastric mammals and birds. Because of the nutritional and environmental problems caused by phytic acid, development of cultivars with low phytic acid (lpa) mutations has become an important objective in many soybean breeding programs. Information about the inheritance of...

introduction phytic acid is a main compound in all plant seeds and contains 60 to 70% of total phosphorus in plant. monogastric animals cannot use phytatephosphorus because of low phytase activity in their digestive tract. thus in addition to unabsorbed mineral phosphorus, phytate phosphorus in fecal ofmonogastric animals may affect water and environment pollution. it is suggested to use of phy...

Greater production demands for ruminants require increased dietary inclusion of high-energy feeds. Grains and oil seeds are most commonly used to enhance diet energy density. However, use of such feeds proportionally increases the amount of dietary phytate phosphorus (P), which the ruminant may not be able to fully utilise. Our objectives for this study were to determine the extent of phytate d...

In children the demand for calcium is particularly great and since their diet may contain considerable amounts of phytate, which is known to impair calcium absorption in adults (McCance & Widdowson, 1942) and in infants (Hoff-Jorgensen, Andersen, Begtrup & Nielsen, 1946), we have investigated the effect of a diet rich in phytate on the absorption of calcium and phosphorus in two children aged 1...

Phytic acid is a bioactive compound widely distributed in plant foods. Due to its molecular structure, phytic acid has affinity to polyvalent cations, such as minerals and trace elements, and could in this way interfere with their intestinal absorption in man and animals. Most studies in humans have therefore concentrated on the effect of phytate on mineral absorption and deficiencies. Currentl...
