“…This detection showed a linear calibration curve up to l100 nmol phytic acid and a detection limit of 1 -2 nmol phytic acid, measured at 290 nm [15]. It was based on earlier observations by Imanari et al [406], who found Fe 3+ -ions highly appropriated to form soluble complexes with inositol phosphates under acidic conditions, allowing for quantitative in-line determination by means of postcolumn derivatisation.…”

The article gives an overview of phytic acid in food and of its significance for human nutrition. It summarises phytate sources in foods and discusses problems of phytic acid/phytate contents of food tables. Data on phytic acid intake are evaluated and daily phytic acid intake depending on food habits is assessed. Degradation of phytate during gastro-intestinal passage is summarised, the mechanism of phytate interacting with minerals and trace elements in the gastro-intestinal chyme described and the pathway of inositol phosphate hydrolysis in the gut presented. The present knowledge of phytate absorption is summarised and discussed. Effects of phytate on mineral and trace element bioavailability are reported and phytate degradation during processing and storage is described. Beneficial activities of dietary phytate such as its effects on calcification and kidney stone formation and on lowering blood glucose and lipids are reported. The antioxidative property of phytic acid and its potentional anticancerogenic activities are briefly surveyed. Development of the analysis of phytic acid and other inositol phosphates is described, problems of inositol phosphate determination and detection discussed and the need for standardisation of phytic acid analysis in foods argued.

“…The eluents were mixed with 1 g L −1 Fe(NO 3 ) 3 × 9H 2 O in a 20 g L −1 solution of HClO 4 (0.4 mL min −1 ) in a postcolumn reactor according to the method of Imanari et al . (). The inositol phosphates were detected at 290 nm and quantified against an external IP6 standard curve using the Chromeleon software (Dionex).…”

Phytase and sodium diformate supplementation in a plant-based diet improves protein and mineral utilization in rainbow trout (Oncorhynchus mykiss)

et al. 2015

A basal isonitrogenous and isoenergetic plant-based diet (Control) was supplemented with either 10 g kg À1 sodium diformate (NaDF), 4000 FTU kg À1 phytase (Phy) or a combination of both additives (NaDF + Phy). Three hundred juvenile rainbow trout with an average weight of 120 g were randomly distributed into 12 fibreglass tanks (300 L). After 65 days of trial, fish fed diets containing phytase, NaDF or the combination of both additives showed a higher growth rate (P < 0.05) compared to fish fed Control diet. NaDF increased feed intake (P = 0.032), while phytase inclusion resulted in a better feed conversion ratio (P < 0.0001) and a higher N retention efficiency (P = 0.02) compared with the Control. Apparent digestibility of P, Ca, Mg and Zn was improved by the use of phytase (P < 0.005) as well as P, Ca and Mg retention efficiency in fish (P < 0.0001). Using 4000 FTU kg À1 phytase in plant-based diets resulted in a 13% and 50% reduction in N and P loadings, respectively. The use of NaDF in combination with phytase in a plant-based diet for rainbow trout resulted in a higher weight gain than that when NaDF was used alone.

“…Several groups have adapted the spectrophotometric detection of cyanide and thiocyanate in blood and urine based on the König reaction ( Figure 2) to RP-HPLC (153,162,223,227). This reaction has also been used for HPLC with fluorometric detection.…”

Cyanide is a toxic chemical that may be introduced into living organisms as a result of natural processes and/or anthropogenic uses (legal or illicit). Exposure to cyanide can be verified by analysis of cyanide or one of its breakdown products from biological samples. This verification may be important for medical, law-enforcement, military, forensic, research, or veterinary purposes. This review will discuss current bioanalytical techniques used for the verification of cyanide exposure, identify common problems associated with the analysis of cyanide and its biological breakdown products, and briefly address the metabolism and toxicokinetics of cyanide and its breakdown products in biological systems.
