Дифосфаты (E450)

Что это такое

Дифосфаты — фосфатные соли, которые разрыхляют тесто и стабилизируют кислотность; их широко применяют в производстве печенья и кексов ¹².

Под обозначением E 450 объединены соли дифосфорной кислоты, которые называют также пирофосфатами: дифосфаты динатрия (i), тринатрия (ii), тетранатрия (iii), тетракалия (v) и дикальция (vi), а также дигидродифосфаты кальция (vii) и магния (ix); в Международной системе нумерации пищевых добавок (INS) им присвоены те же номера ¹.

Насколько широко они применяются

В апреле 2019 года дифосфаты были указаны в составе 6529 из 126 556 фасованных пищевых продуктов французского рынка; по частоте применения они занимали восьмое место среди добавок ².

Из 106 489 взрослых участников когорты NutriNet-Santé их потребляли 64,36%, в среднем 178,33 mg/day; допустимое суточное потребление превышали 0,02% участников ³.

В организме

В кишечнике дифосфаты расщепляются до обычного фосфата, который в основном всасывается, а затем выводится с мочой ¹.

У крыс дифосфат тетранатрия, добавленный в корм, почти полностью гидролизовался; у человека 80–90% фосфора пищевых добавок всасывается в форме ортофосфата ¹. В проксимальных канальцах почек реабсорбируется не менее 80% профильтрованного фосфора; этот процесс регулируют паратиреоидный гормон и фактор роста фибробластов 23 (FGF23) ¹.

Что показывают исследования

В кратковременных исследованиях с участием людей дополнительное поступление фосфата повышало уровень гормона, регулирующего его обмен, и на короткое время ухудшало способность артерий расширяться ⁴⁵.

У 10 взрослых уровень FGF23 после недели питания продуктами с высоким содержанием добавок был на 23% выше, чем после недели питания продуктами с низким их содержанием; в рационе, богатом добавками, фосфора было больше на 606 mg/day, а натрия — на 58 mmol/day ⁴. У 11 мужчин поток-зависимая вазодилатация плечевой артерии через 2 часа после приёма пищи, содержавшей 1200 mg фосфора, составила 5,02%, а после пищи с 400 mg фосфора — 8,42% ⁵. В кластерном рандомизированном испытании с участием 279 пациентов на гемодиализе с гиперфосфатемией у тех, кому рекомендовали избегать фосфатсодержащих пищевых добавок, изменение концентрации фосфора в сыворотке за 3 месяца по сравнению с группой обычной медицинской помощи составило −0,6 mg/dL (95% ДИ от −1,0 до −0,1) ⁶.

В когорте NutriNet-Santé потребление дифосфатов не было связано с сердечно-сосудистыми заболеваниями или сахарным диабетом 2 типа ⁷⁸. При среднем сроке наблюдения 6,7 года рак молочной железы в пременопаузе развился у 113 из 19 382 человек в трети с наибольшим потреблением и у 61 из 16 560 — в трети с наименьшим (отношение рисков 1,45; 95% ДИ 1,04–2,02; рассчитанный с помощью модели абсолютный риск к 40 годам — 2,5% против 1,7%) ⁹.

Групповое допустимое суточное потребление фосфатов, установленное Европейским агентством по безопасности пищевых продуктов (EFSA), составляет 40 mg фосфора на 1 kg массы тела в сутки, учитывает весь фосфор, поступающий с пищей, и не распространяется на людей с умеренным или тяжёлым нарушением функции почек; по оценкам EFSA, среднее поступление фосфора со всем рационом превышало эту величину у младенцев и детей, в том числе раннего возраста ¹.

E 450 comprises disodium diphosphate (E 450(i)), trisodium diphosphate (E 450(ii)), tetrasodium diphosphate (E 450(iii)), tetrapotassium diphosphate (E 450(v)), dicalcium diphosphate (E 450(vi)), calcium dihydrogen diphosphate (E 450(vii)) and magnesium dihydrogen diphosphate (E 450(ix)); JECFA specifications carry the same INS sub-numbers. Formulae are Na2H2P2O7, Na3HP2O7, Na4P2O7, K4P2O7, Ca2P2O7, CaH2P2O7 and MgH2P2O7; synonyms include disodium pyrophosphate, tetrasodium pyrophosphate, tetrapotassium salt of diphosphoric acid, calcium pyrophosphate and acid calcium and acid magnesium pyrophosphate. Diphosphate, also named pyrophosphate, is M4P2O7; sodium diphosphates are made by neutralising phosphoric acid with sodium hydroxide and drying above 200 °C, which condenses phosphate groups. JECFA functional classes (Appendix A) include raising agent for E 450(i), (ii), (vi), (vii) and (ix), sequestrant for (i) and (iii), emulsifier for (ii), (iii), (v) and (vii), emulsion stabiliser for (ii), (vii) and (ix) and buffer, including acidity regulator, for (iii) and (vi). Phosphate additives are assumed to dissociate in the gastrointestinal tract; inorganic phosphorus from food additives is absorbed at about 80 to 90% as free orthophosphate, without metabolism, by passive diffusion and sodium-dependent active transport; NaPi-IIb (SLC34A2) predominates in the intestine and is modulated by active vitamin D and low phosphorus intake. About 200 mmol of phosphorus is filtered daily, 80% or more is reabsorbed in proximal tubules mainly via NaPi-IIa, and PTH and FGF-23 with Klotho influence reabsorption; excretion is via the kidney. In rats fed 5% tetrasodium diphosphate, diphosphate was undetected in faeces and urine, hydrolysis to orthophosphate in the gut was almost complete and about 85% was absorbed; toxicokinetic data on dicalcium and calcium dihydrogen diphosphate are lacking. The only significant adverse effect of phosphates in animal studies was kidney calcification and tubular nephropathy; a 90-day rat study of tetrasodium diphosphate gave a NOAEL of 500 mg/kg bw per day (116 mg P/kg bw per day). A group ADI of 40 mg/kg bw per day, expressed as phosphorus, was derived for E 338–341, E 343 and E 450–452 from a chronic rat NOAEL of 76 mg P/kg bw per day plus 91 mg P/kg bw per day background diet (167 mg P/kg bw per day) divided by an adjustment factor of 4; it covers phosphorus from all sources, natural ones included, and does not apply to people with moderate to severe reduction in renal function. Mean whole-diet exposure estimated from analytical data ranged across surveys from 16 mg P/kg bw per day in adults and the elderly to 85 mg P/kg bw per day in infants aged 12 weeks to 11 months; it exceeded the ADI at the mean for infants, toddlers and children, and at the 95th percentile also for adolescents (highest 95th percentile 123 mg P/kg bw per day, in toddlers). Exposure from food additives indicatively contributed 6 to 21% of total mean intake in all groups except infants and 12 to 30% in infants aged 12 weeks to 11 months. In the EU, phosphates (E 338–341, E 343, E 450–452) were authorised with maximum permitted levels of 500 to 20,000 mg/kg expressed as P2O5 in 104 uses and at quantum satis in four.

53.8% of products contained at least one additive and 11.3% five or more. Appendix 7, products containing each additive: citric acid E 330 18,302; lecithins E 322 13,102; E 14XX modified starches 10,100; sodium carbonates E 500 8587; ascorbic acid E 300 7919; xanthan gum E 415 7327; sodium nitrite E 250 7144; diphosphates E 450 6529; pectins E 440 6504; mono- and diglycerides of fatty acids E 471 6060. Specific starches: E 1442 209, E 1422 173, E 1414 55, E 1450 30, E 1412 27, E 1420 19, E 1404 18, E 1440 5, E 1410 1. The footnote and the Discussion state that the number of products containing each specific modified starch may be underestimated because packaging often states only 'modified starch'. E 500 had the highest squared loading (0.64) in cluster 3, 'stabilizers and emulsifiers mostly used in biscuits and cakes'; sodium carbonate (E 500), diphosphates (E 450) and lecithins (E 322) co-occurred in 1667 products, mostly biscuits. The authors describe E 500, E 450, E 503 and E 422 as widely used in biscuits and cakes as acidity regulators, stabilizers and emulsifiers. Additive doses were not available.

Non-randomised fixed-sequence feeding study: 1 week of a low-additive diet followed by 1 week of an additive-enhanced diet with identical food items containing phosphorus additives. Measured phosphorus was 1070 ± 58 and 1677 ± 167 mg/day (difference 606 ± 125 mg/day, P < .001) and sodium 89 ± 28 and 148 ± 28 mmol/day (difference 58 ± 27 mmol/day, P = .02); calcium, potassium and energy did not differ significantly. After the additive-enhanced week, plasma FGF23 was 23% higher than at the end of the low-additive week (P = .03), and osteopontin and osteocalcin were 10% and 11% higher (P = .01 and .04); mean sclerostin fell over time (P = .02 for the main effect of time) but not significantly against the preceding diet period (P = .10). Over the 2 weeks, changes in serum phosphorus, calcium, PTH, P1NP, CTX and FGF23 (main effect of time P = .19) were not statistically significant. In mice, a 1.8% against a 0.2% phosphorus diet raised serum FGF23, osteopontin and osteocalcin at 5 and 15 weeks, lowered sclerostin at 15 weeks and reduced bone mineral density.

Double-blind crossover study on two days separated by more than 1 day: breakfast meals containing 400 mg (P400) or 1200 mg (P1200) phosphorus. Mean ± SEM serum phosphorus 2 h after the meal was 3.66 ± 0.2 mg/dL after P400 and 4.56 ± 0.1 mg/dL after P1200, above the normal range in 8 of 11 men. Flow-mediated dilation of the brachial artery was 8.81 ± 0.3% before and 8.42 ± 0.5% 2 h after P400, and 9.26 ± 0.4% before and 5.02 ± 0.3% 2 h after P1200 (P < 0.0001 between meals); it was 8.60 ± 0.2% 24 h after P1200. After P1200, flow-mediated dilation correlated inversely with serum phosphorus (Spearman rs = -0.42, P = 0.006). In bovine aortic endothelial cells, raised extracellular phosphate increased reactive oxygen species production, which the sodium-phosphate transport inhibitor phosphonoformic acid reduced, and inhibited bradykinin-stimulated nitric oxide production, with protein kinase C-dependent phosphorylation of endothelial nitric oxide synthase at Thr497; preincubation in 2.4 mM against 1.2 mM phosphate reduced acetylcholine-induced relaxation of rat aortic rings by 70%.

Cluster randomisation by dialysis shift (or by facility for 2 single-shift facilities). Intervention participants (n = 145) received about 30 minutes of education on avoiding phosphorus-containing additives, with a magnifier case listing them (among them pyrophosphate and sodium acid pyrophosphate) and fast-food handouts; control participants (n = 134) continued usual care. Baseline mean serum phosphorus was 7.2 and 7.1 mg/dL. After 3 months serum phosphorus fell by 1.0 mg/dL in the intervention group (P < .001) and 0.4 mg/dL in the control group (P = .02); the difference was 0.6 mg/dL larger with the intervention (95% CI -1.0 to -0.1 mg/dL). Missing data from 28 participants were multiply imputed. No adverse events were associated with the intervention; dietary intake and adherence were not measured.

2604 incident cancers (750 breast, 322 prostate, 207 colorectal) over 615,749 person-years. Highest versus lowest intake of E471: overall cancer HR 1.15 (95% CI 1.04 to 1.27), breast 1.24 (1.03 to 1.51), prostate 1.46 (1.09 to 1.97); total carrageenans and breast cancer 1.32 (1.09 to 1.60). No emulsifier was associated with colorectal cancer. Modelled absolute risks at age 60 by intake category (eTable C): overall cancer 11.2%, 11.8% and 12.4% for E471; breast cancer 4.2%, 4.7% and 5.1% for E471 and 4.1%, 4.6% and 5.2% for total carrageenans; prostate cancer 3.6%, 4.2% and 4.9% for E471. E471 was coded in sex-specific thirds (cut-offs 34 and 187.3 mg/day in men, 40.4 and 177.8 mg/day in women; category means 7.16, 104.17 and 376.1 mg/day). eTable D, cases/participants by third of E471 intake: overall cancer 790/30,667, 1018/30,729 and 796/30,604, HR 1.00, 1.16 (1.05 to 1.27) and 1.15 (1.04 to 1.27), p-trend 0.01; breast cancer 211/24,090, 292/24,153 and 245/24,027; prostate cancer 86/6,577, 133/6,576 and 103/6,577. Total mono- and diglycerides of fatty acids (E471, E472, E472a, E472b, E472c, E472e) and overall cancer: HR 1.12 (1.02 to 1.23) and 1.03 (0.93 to 1.14), p-trend 0.4. Diphosphates (E450) were consumed by 72.6%, mean 246.7 (SD 341.0) mg/day, and coded in sex-specific thirds (cut-offs 47.3 and 259.5 mg/day in women, 28 and 264.3 mg/day in men; category means in women 4.85, 145.42 and 580.06 mg/day). eTable D, E450 by third: premenopausal breast cancer 61/16,560, 120/17,021 and 113/19,382, HR 1.00, 1.56 (1.13 to 2.15) and 1.45 (1.04 to 2.02), p-trend 0.03 (false-discovery-rate-adjusted p-trend 0.1); overall cancer 838/30,683, 1036/30,658 and 730/30,659, HR 1.00, 1.03 (0.94 to 1.13) and 0.98 (0.88 to 1.09), p-trend 0.97; breast cancer HR 1.14 (0.94 to 1.40) for the highest third, p-trend 0.08. eTable C modelled absolute risk of premenopausal breast cancer at age 40 by E450 third: 1.7%, 2.1% and 2.5%. Additive doses were estimated from laboratory assays, EFSA doses by food category or Codex GSFA doses; the study period was 2009 to 2021. The authors state that further human, epidemiological and preclinical studies are required to elucidate the potential underlying mechanisms.

Recommendation 4.1.8: 'In patients with CKD G3a–G5D, we suggest limiting dietary phosphate intake in the treatment of hyperphosphatemia alone or in combination with other treatments (2D). It is reasonable to consider phosphate source (e.g., animal, vegetable, additives) in making dietary recommendations (Not Graded).' The rationale states that food additives contain inorganic phosphate, which is more readily absorbed and likely to be underreported in nutrient databases, and that efforts to restrict dietary phosphate must not compromise adequate protein intake.
