The Panel on Food Additives and Flavourings added to Food (FAF) provided a scientific opinion re-evaluating the safety of phosphates (E 338-341, E 343, E 450-452) as food additives. The Panel considered that adequate exposure and toxicity data were available. Phosphates are authorised food additives in the EU in accordance with Annex II and III to Regulation (EC) No 1333/2008. Exposure to phosphates from the whole diet was estimated using mainly analytical data. The values ranged from 251 mg P/person per day in infants to 1,625 mg P/person per day for adults, and the high exposure (95th percentile) from 331 mg P/person per day in infants to 2,728 mg P/person per day for adults. Phosphate is essential for all living organisms, is absorbed at 80-90% as free orthophosphate excreted via the kidney. The Panel considered phosphates to be of low acute oral toxicity and there is no concern with respect to genotoxicity and carcinogenicity. No effects were reported in developmental toxicity studies. The Panel derived a group acceptable daily intake (ADI) for phosphates expressed as phosphorus of 40 mg/kg body weight (bw) per day and concluded that this ADI is protective for the human population. The Panel noted that in the estimated exposure scenario based on analytical data exposure estimates exceeded the proposed ADI for infants, toddlers and other children at the mean level, and for infants, toddlers, children and adolescents at the 95th percentile. The Panel also noted that phosphates exposure by food supplements exceeds the proposed ADI. The Panel concluded that the available data did not give rise to safety concerns in infants below 16 weeks of age consuming formula and food for medical purposes.

“…However, the quantitative accuracy of NMR analysis has improved rapidly in recent years, and quantitative accuracy of three significant figures (with errors of 0.5% or less) is now possible. As a result, high-accuracy quantitative NMR (qNMR) analysis can be achieved while retaining the advantages of NMR spectroscopy, [18][19][20][21][22][23][24][25][26][27][28] such as its non-destructive nature and simultaneous multicomponent analysis. Previously, assuming that all of the observable nuclei were detected, the concentrations of specific chemical species and functional groups in the measured sample could be determined from the relative intensities of each NMR signal.…”

“…qNMR analysis has been reported for many dipolar nuclei. [18][19][20][21][22][23][24][25][26][27][28] However, qNMR spectroscopy of quadrupolar nuclei, which includes that of many metallic nuclei, has not yet been reported because of the fundamental differences in the governing factors of the nuclear magnetic relaxation process for quadrupolar and dipolar nuclei.…”

In this study, quantitative nuclear magnetic resonance (qNMR) spectroscopy of quadrupolar nuclei has been established. The complicated hydrolysis behavior of the Al ion, which causes fish poisoning and inhibits the growth of plants in environmental water, was clarified by Al qNMR spectroscopy. Highly accurate simultaneous multicomponent quantitative analysis of various hydrolyzed forms of the Al ion was achieved in a non-destructive manner. The calibration curve of the external standard aqueous Al(NO) solution showed excellent linearity over a very wide concentration range from 1 × 10 to 1 mol L (an increase in concentration of 10 000 times), with a simple experimental and analytical procedure. Furthermore, the weaknesses of the conventional Ferron assay and the advantages of Al qNMR spectroscopy were considered. The quantitative determination error for the free [Al(HO)] ion and the trinuclear complex, which has a high complexation rate, is higher in the Ferron assay than in the Al qNMR technique. The concentrations of four Al species were directly determined byAl qNMR, namely, free [Al(HO)], the trinuclear complex, Al(OH), and tridecameric hydrolyzed Al, which has a Keggin structure. The concentration of the tridecamer rapidly increased until 100 min after NaOH addition, and showed a local maximum after 1 week. In addition, the concentration of colloidal Al hydroxide, which cannot be detected by NMR spectroscopy, was determined by numerical analysis. This species was generated in the initial stage of reaction, and then the tridecamer formed very slowly.

Processors appreciate the proven value of phosphates to increase the yield and functionality of the fish meat products. Our studies showed that the hydrolysis rate of PP or TPP in the blend was slower than that of polyphosphate alone. Thus, it is likely that the addition of PP and TPP in a polyphosphate blend had a prolonged interaction with proteins in fish meat processing and the effectiveness of polyphosphates was enhanced.
