Sodium ntsev: hauj lwm, daim ntawv thov, los ntawm lub cev

Sodium ntsev (hais kom raug: sodium phosphate, phosphate, pob txha phosphate los yog Na ₃ PO ₄₎ - dawb hygroscopic ntsev nruab nrab, thiab thermally ruaj khov kub yaj tsis decomposition (ntawm ib tug kub ntawm 250 degrees los yog siab dua). Nws soluble nyob rau hauv dej, tsim ib tug xav alkaline medium.

Sodium ntsev yog npaj nyob rau hauv qhov kev txiav txim ntawm alkali rau phosphoric acid (neutralization) nyob rau hauv degidrotatsii dibasic sodium.

Nws siv raws li emulsifiers thiab pH regulators, raws li zoo raws li anti-caking agents. Sodium ntsev producers siv detergents. Tshwj xeeb tshaj yog cov triphosphate yog feem ntau siv, nyob rau hauv uas lub hmoov tej zaum yuav mus txog li 50%. Rau dej softening (tshem tawm ntawm hardness) degidrotirovannymi yog cov tshuaj uas tsim ib tug complex nrog ib tug xov tooj ntawm cov hlau (magnesium, poov hlau, barium, etc.). Sodium ntsev (technical, nyob rau hauv lub los "B") siv nyob rau hauv qhov siv thiab ua cov iav, xim, nyob rau hauv ore hnav khaub ncaws. Tab sis Na ₂ HPO ₄ • 12H ₂ O (khoom noj khoom haus, nyob rau hauv lub los "A") yog siv feem ntau nyob rau hauv cov zaub mov kev lag luam raws li ib tug disintegrant. Nws pab txoj kev lub taub hau ntawm condensed mis nyuj, cheese, sausages. Yog siv rau electrophoresis sodium phosphate (electrolytic dab) thiab duab (raws li tsim tawm tivthaiv).

Xav txog orthophosphate ntau.

Sodium tripolyphosphate yog ua nyob rau hauv ob cim "A", "B". Tsuas yog fej nyob rau hauv tshwj xeeb ntim MKP-1, yog nqa nyob rau hauv txawm peem rau (tshwj xeeb) mineral chiv. Txee lub neej tsis muaj kev txwv.

Trisodium phosphate (sodium phosphate, trisodium) siv nyob rau hauv khoom noj khoom haus ua, sis plawv hniav thiab cov ntawv industries, nyob rau hauv lub zog ntau lawm ntawm hmoov, tu pastes, detergents rau cav ntxuav tais diav thiab raws li ib tug surfactant nyob rau hauv zus tau tej cov MAAs. Thaum drilling (roj kev lag luam) yog muaj raws li ib tug polymer additive. Trisodium Phosphate zoo heev degreasing qhov chaw ntawm tej khoom siv, yog li nws yog nyob rau hauv kev thov rau ntxuav. Externally zoo xws li cov dos (muaju) nrog alkaline zog, uas tsis yog-flammable. Nws yuav tsum tau nyob rau hauv lub thib ob chav kawm ntawv ntawm kev txaus ntshai rau cov teebmeem nyob ntawm tib neeg lub cev.

Nws yog ib zajlus kom lo lus nug: "Nrog xws li ib tug dav siv Tsis txhob coj raug mob rau peb lub cev sodium phosphate?"

Antioxidant (ntawv nws yog muab teev raws li cov E-300 (thiab E-339) tso cai rau kom khaws cia cov nqaij daim tawv, kom tsis txhob muaj cov tsos ntawm bitterness thiab tiv thaiv oxidation. Qhov no yuav ua tau ib yam compound (vitamin E, paub ascorbic acid) thiab tsim sib, tsis pom nyob rau hauv cov xwm. Nws yog ntxiv rau cov emulsion muaj ib cov roj (e.g. mayonnaise, ketchup). ntxiv thaj chaw ntawm emulsifier thiab stabilizer, Na ₃ PO ₄ yog ib tug dej-ceev neeg sawv cev, complexing neeg sawv cev, stabilizer. Piv txwv li, nyob rau hauv ci nrog loj tagnrho (bakeries, bakeries) cr Aine tseem ceeb siab ua khob noom cookie sawv, thiab ib tug ntxeem tau thiab teeb tus qauv. Ntawm no tus nqi ntawm cov tshuaj tiv thaiv ntawm cov sodium bicarbonate thiab ntsev ntawm phosphoric acid cia li tau nyob rau hauv ib tug yam nyhuv. Tshwj xeeb tshaj yog nrov hloov kho ntawm E-450 (SAPP, sodium pyrophosphate). Qhov no disintegrant tso cai rau yav tom ntej lub xeem lifting (lub siab tshaj plaws nyob rau hauv kev sib piv nrog analogues) thiab ntxiv tom qab ci. ntxiv rau cov ncuav muffins, tortillas, ncuav, pizzas, pastry. pom zoo rau zoo yam khob noom cookie (poov khov, whipped, xuab zeb crumbly nd).

Tsis E-450 zog, raws li zoo raws li lub peev xwm mus khi calcium siv nyob rau hauv dairies. Pyrophosphate yeej ua rau cov casein - nws qhib, swells thiab ua raws li ib tug emulsifier, uas yuav pab tau nyob rau hauv qhov kev npaj ntawm puddings, mis nyuj imitation khoom, khoom qab zib. Condensed mis nyuj tau los ntawm extracting cov dej, dhau lawm, tsis yog tsis muaj ntsev stabilizer DSP (disodium phosphate sodium).

Nyob rau hauv cov nqaij ua lag luam, ua tsaug rau peb kev sib tham emulsifiers, ho ua rau kom tag nrho cov zis ntau lawm thiab stabilization ntawm kev ntxhib los mos thiab xim txhim kho.

Daim ntawv thov ntawm cov khoom muaj ib tug muaj pes tsawg leeg ntawm sodium phosphates (los yog npaj nrog lawv daim ntawv thov), nws yog ib qho zoo kom tsis txhob vim hais tias sai losis tswvyim dabtsi ntawm calcium ua rau ib tug tsis muaj peev xwm ntawm lub yav tas rau hauv lub cev. Nyob rau hauv tas li ntawd, qhov no tshuaj yog ib tug tswv cuab ntawm cov tshuaj ntaus cev, txawm li cas los ib tug ntau npaum li cas ntawm cov hnyuv ntxwm peev xwm cuam tshuam txoj hnyuv ib ntsuj av.
