“…Simons et al (1990) ascribed this effect to the release of minerals from their complex with phytate and/or utilisation of inositol. Other possible reasons are an increase in starch digestibility (Knuckles and Betschart, 1987) and bioavailability of proteins (Smith and Rackis, 1957).…”

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on broiler performance and tibia ash. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemented phytase had beneficial effects on broiler performance. It significantly increased body weight gain (P < 0.0003) and feed consumption (P < 0.0361) by 6 and 7% in comparison with the control groups, respectively. No influence on feed conversion ratio and tibia ash was detected. Both body weight gain and feed intake were also significantly influenced by different cereals (P < 0.0001 and 0.0348, respectively). The increasing dietary calcium level resulted in a significant increase in body weight gain (P < 0.0024) and tibia ash (P < 0.0016). Effects of 500 and 1 000 PU/kg were not statistically different between themselves.

“…Phosphorus availability is likely to be coupled with N availability in struvite but not necessarily for phytin. While struvite has a congruent dissolution of PO 4 3− and NH 4 + ions as an inorganic P source, calcium phytin as the calcium salt of inositol polyphosphate is an organic P source containing coprecipitated N largely in proteinaceous forms (Fontaine et al, 1946; Smith and Rackis, 1957). The dominance of organic forms of phytin N entails uncertainty in the amount of N release via mineralization and is not necessarily related to mineralization of organic P. Thus, N release from phytin is likely to be less predictable than struvite and more influenced by interrelated abiotic (e.g., weather conditions) and biotic factors (e.g., soil microbiological activity).…”

Redirecting anthropogenic waste phosphorus (P) flows from receiving water bodies to high P demand agricultural fields requires a resource management approach that integrates biogeochemistry, agronomy, engineering, and economics. In the US Midwest, agricultural reuse of P recovered from spatially colocated waste streams stands to reduce point‐source P discharges, meet agricultural P needs, and—depending on the speciation of recovered P—mitigate P losses from agriculture. However, the speciation of P recovered from waste streams via its chemical transformation—referred to here as recovered P (rP) differs markedly based on waste stream composition and recovery method, which can further interact with soil and crop characteristics of agricultural sinks. The solubility of rP presents key tensions between engineered P recovery and agronomic reuse because it defines both the ability to remove organic and inorganic P from aqueous streams and the crop availability of rP. The potential of rP generation and composition differs greatly among animal, municipal, and grain milling waste streams due to the aqueous speciation of P and presence of coprecipitants. Two example rP forms, phytin and struvite, engage in distinct biogeochemical processes on addition to soils that ultimately influence crop uptake and potential losses of rP. These processes also influence the fate of nitrogen (N) embodied in rP. The economics of rP generation and reuse will determine if and which rP are produced. Matching rP species to appropriate agricultural systems is critical to develop sustainable and financially viable regional exchanges of rP from wastewater treatment to agricultural end users. Core Ideas There is high potential for recovering P (rP) from point sources for agricultural reuse. rP speciation depends on recovery source and method, interacts with soils and crops. Engineering, agronomic, and economic considerations of rP are context‐specific.

“…Optimal removal Downloaded by [New York University] at 14:53 05 June 2015 of soluble, unbound phytic acid (at pH 7.0), without appreciable removal of proteins has been investigated by Smith and Rackis. 398 Dialysis seems impractical on commercial scale. 61 Ultrafiltration (UF) seems promising for selective removal of low molecular weight components.…”

Beans of Phaseolus are important food crops both economically and nutritionally, and are cultivated and consumed world wide. With ever rising costs of meats, fresh fruits, and vegetables, dry beans are expected to contribute more to the human nutrition in coming years. Traditionally, they have been referred to as "poor man's meat" and have contributed significantly to the diets of many people of several countries in Asia, Africa, the Middle East, and South America. In recent years, a renewed interest in bean research in Western European countries and the U.S. is evident. In this review, certain biochemical, technological, nutritional, and toxicological aspects are discussed and the limitations and problems associated with dry beans of Phaseolus as human food are addressed.
