Popular questions
Is guar gum bad for you?
No—E412 (guar gum) is generally recognized as safe at typical food levels. As a soluble fiber it can cause gas or loose stools in some people, and concentrated tablets or dry powder taken without enough liquid have been linked to blockage risks.
What is guar gum made from?
It’s a galactomannan polysaccharide made from the endosperm of guar beans (Cyamopsis tetragonoloba), processed into an off‑white powder.
Is guar gum bad for cats?
It’s generally considered safe at the small amounts used as a thickener in many canned cat foods. Some cats may get soft stools or gas, especially if sensitive, so monitor tolerance and consult a vet if issues arise.
Can dogs have guar gum?
Yes—at the low levels used in commercial dog foods it’s considered safe. Too much may cause gas or diarrhea, so introduce new foods gradually and watch your dog’s tolerance.
Is guar gum bad for dogs?
Not at typical food levels; it’s widely used as a safe thickener in dog foods. Large amounts may upset the stomach (gas, loose stools).
How does polyphosphate remove calcium?
It acts as a sequestrant: the polyphosphate chain binds Ca2+ at multiple oxygen sites to form soluble complexes, preventing calcium from precipitating or causing scale/texture issues. Over time, hydrolysis to orthophosphate can convert some bound calcium into insoluble calcium phosphate, effectively removing it from solution.
What is the e number of calcium polyphosphate?
E452iv.
When calcium ions complex with sodium metaphosphate, a solid calcium phosphate precipitate forms?
Not initially—calcium typically remains in soluble complexes with sodium metaphosphate (a polyphosphate). Precipitation of calcium phosphate generally occurs after the polyphosphate hydrolyzes to orthophosphate or under conditions (e.g., high pH/aging) that drive conversion.
