Popular questions
Girlsdoporn e452 who is she?
That appears unrelated to the food additive E452; E452 refers to polyphosphates, synthetic phosphate salts used in foods as emulsifiers, stabilizers, humectants, and sequestrants.
How does polyphosphates reduce affinity of hemoglobin for oxygen?
Inorganic polyphosphate can bind to positively charged sites on deoxyhemoglobin and stabilize the low‑affinity T-state, shifting the oxygen dissociation curve to the right and lowering O2 affinity. This is a biochemical interaction and not a typical food-use effect of E452.
How many states use polyphosphates?
There’s no official tally; polyphosphates are used by many water utilities across numerous U.S. states and worldwide for iron/manganese sequestration and scale/corrosion control, depending on local water chemistry.
How many states use polyphosphates to treat water?
No centralized count exists, but hundreds of U.S. community water systems in dozens of states use phosphate-based treatments (often polyphosphates or poly/ortho blends) for metal sequestration and corrosion control. Usage changes over time with source water and regulations.
How to remove polyphosphates from drinking water?
Effective options include reverse osmosis or nanofiltration, and strong‑base anion exchange; utilities may also use coagulation/precipitation with iron or alum followed by filtration. Polyphosphates hydrolyze to orthophosphate over time, which the same processes remove; activated carbon and boiling are generally ineffective.
How long to soak oats to remove phytic acid?
About 12–24 hours in warm water with a little acid (e.g., yogurt or lemon) plus a phytase source such as rye flour or sourdough can substantially reduce phytic acid; a plain cold overnight soak removes relatively little.
How to remove phytic acid from oats?
Soak oats 12–24 hours in warm water with a small amount of acid and a phytase-rich addition (e.g., rye flour or sourdough), then cook and discard the soak water; this activates enzymes that break down phytic acid. Fermenting into a sour porridge or sprouting also helps, while plain soaking alone is less effective.
Does white rice have phytic acid?
Yes, but at much lower levels than brown rice because most phytic acid is in the bran and germ that are removed during polishing; white rice typically contains only trace-to-low amounts.
How long to soak cashews to remove phytic acid?
Soak 2–4 hours to soften and reduce a little phytic acid; extending to 8–12 hours in warm, lightly salted or acidic water may help slightly more, but significant reduction usually requires additional steps like boiling or roasting.
How to soak oats to remove phytic acid?
Cover oats with warm water, add a spoonful of acidic medium (yogurt/lemon) and a phytase source (rye flour or sourdough), soak 12–24 hours, then cook and discard the soaking liquid for best phytic acid reduction.
