Tetrasodium Pyrophosphate (TSPP)

Feem ntau yog siv rau hauv cov nqaij thiab nqaij nruab deg ua ua cov dej tuav dej, lub stabilizer rau cov xim ntuj thiab tiv thaiv kom tsis txhob muaj rog. Nws kuj tseem tuaj yeem siv pH hloov pauv, emulsifier, ua kom zoo dua tus neeg sawv cev hauv khob noom cookie thiab ua cov khoom noj ntxiv.

Nta

Dawb crystalline los yog granular nyob rau hauv tsos, tsis muaj xim. Lub decahydrate effloresces me ntsis hauv huab cua qhuav.

Tetrasodium pyrophosphate yog tsim los ntawm cov tshuaj tiv thaiv ntawm furnace-qib phosphoric acid nrog sodium carbonate los tsim disodium phosphate, uas yog ces rhuab mus rau 450 degree los tsim tetrasodium pyrophosphate:

2 Naj₂HPO₄→ Na₄P₂O₇ + H₂O

Daim ntawv thov

Tetra Sodium Pyrophosphate (TSPP) yog ib tug thickening tus neeg saib xyuas thiab emulsifier. Nws yog feem ntau siv rau hauv qaib nuggets, kaus poom tuna, imitation crab nqaij, paj npleg, marshmallows, thiab soy-based nqaij lwm txoj kev.

Sodium pyrophosphate nyob rau hauv kev ua zaub mov raws li kev txhim kho zoo, emulsifying thiab dispersing tus neeg saib xyuas, tsis, chelating tus neeg saib xyuas, thiab lwm yam, muaj peev xwm ntawm condensation phosphate, chelating thiab dispersing nyhuv yog pom tseeb, muaj peev xwm tiv taus flocculation; tuaj yeem tiv thaiv cov roj oxidation, casein viscosity thiab lwm yam haujlwm. Thaum pH tus nqi siab, nws tuaj yeem cuam tshuam cov zaub mov lwj thiab fermentation. Feem ntau siv rau cov nqaij thiab cov khoom siv dej ua, tuaj yeem txhim kho cov dej tuav, ua kom cov nqaij tshiab thiab sib tw, ruaj khov ntuj xim. Nws tuaj yeem siv rau hauv kev tsim cov hmoov txhuv nplej siab, thiab lwm yam, thiab lwm yam kev siv condensed phosphate composite. Sodium pyrophosphate feem ntau yog ntxiv 0.5-3‰ hauv kev ua zaub mov, thiab qhov siab tshaj plaws ntxiv yog 3% hauv kev ua cov khoom hauv dej.
