Tus neeg saib xyuas cov dej noo yog hais txog ib chav kawm ntawm cov khoom uas tuaj yeem txhim kho kev ruaj ntseg ntawm cov khoom, tswj cov dej sab hauv lub peev xwm ntawm cov khoom noj, thiab txhim kho cov duab, tsw, xim, thiab lwm yam ntawm cov khoom noj thaum lub sij hawm ua zaub mov. Cov khoom ntxiv los pab khaws cia noo noo nyob rau hauv cov zaub mov feem ntau yog xa mus rau phosphates uas yog siv rau hauv cov nqaij thiab cov khoom siv hauv dej ua kom cov dej noo ruaj khov thiab muaj peev xwm tuav tau dej ntau dua.
Phosphate yog tib cov nqaij humectant uas tuaj yeem ua kom cov nqaij muaj protein ntau hauv cov khoom noj nqaij.Kev tsim thiab ua cov khoom siv nqaij yog sib cais los ntawm phosphate.Phosphate feem ntau muab faib ua ob yam, cov khoom monomer thiab cov khoom sib xyaw.
Cov khoom lag luam Monomer: yog hais txog cov phosphates uas tau teev tseg hauv GB2760 Cov Khoom Noj Ntxiv Siv Khoom Noj xws li sodium tripolyphosphate, sodium pyrophosphate, sodium hexametaphosphate, thiab trisodium phosphate.

1. Mechanism ntawm Phosphate los txhim kho nqaij dej tuav:
1.1 Kho tus nqi pH ntawm cov nqaij kom nws siab tshaj qhov isoelectric point (pH5.5) ntawm cov nqaij protein, thiaj li txhim kho cov dej tuav cov nqaij thiab xyuas kom cov nqaij tshiab;
1.2 Ua kom muaj zog ionic, uas muaj txiaj ntsig zoo rau kev tawg ntawm myofibrillar protein, thiab tsim cov qauv sib txuas nrog cov protein sarcoplasmic hauv kev koom tes nrog ntsev, kom cov dej tuaj yeem sib sau ua ke hauv lub network;
1.3 Nws tuaj yeem chelate hlau ions xws li Ca2+, Mg2+, Fe2+, txhim kho dej tuav, thiab tib lub sij hawm txhim kho cov nyhuv antioxidant, vim cov hlau ions yog activators ntawm roj oxidation thiab rancidity.Ntsev chelation, cov carboxyl pawg hauv cov leeg nqaij protein raug tso tawm, vim yog electrostatic repulsion ntawm carboxyl pawg, cov qauv protein yog so, thiab dej ntau tuaj yeem nqus tau, yog li txhim kho cov dej tuav ntawm cov nqaij;
Muaj ntau ntau yam ntawm phosphates, thiab cov nyhuv ntawm ib yam khoom yog ib txwm txwv.Nws tsis tuaj yeem siv ib qho phosphate hauv kev siv cov khoom noj nqaij.Yuav ib txwm muaj ob lossis ntau dua cov khoom phosphate sib xyaw rau hauv cov khoom sib xyaw.
2. Yuav ua li cas xaiv cov khoom sib xyaw ua kom noo noo:
2.1 Cov khoom uas muaj cov ntsiab lus ntawm cov nqaij siab (siab dua 50%): Feem ntau, cov khoom tsim nrog cov phosphate ntshiab yog siv, thiab cov nyiaj ntxiv yog 0.3% -0.5%;
2.2 Cov khoom lag luam nrog cov ntsiab lus qis me ntsis: Feem ntau, qhov sib ntxiv yog 0.5% -1%.Cov khoom zoo li no feem ntau sib xyaw nrog cov haujlwm tshwj xeeb xws li colloids txhawm rau ua kom cov viscosity thiab cohesion ntawm cov filling;
3. Ntau lub hauv paus ntsiab lus rau kev xaiv cov khoom humectant:
3.1 Lub solubility ntawm cov khoom, tus neeg sawv cev tuav tsuas yog siv tau tom qab yaj, thiab cov khoom uas tsis zoo dissolution tsis tuaj yeem 100% ua lub luag haujlwm ntawm cov khoom;
3.2 Lub peev xwm ntawm marinated nqaij filling kom khaws dej thiab tsim xim: Tom qab cov nqaij filling yog marinated, nws yuav muaj elasticity, thiab cov nqaij filling yuav ci;
3.3 Khoom saj: phosphates uas tsis txaus purity thiab tsis zoo yuav muaj astringency thaum lawv tau ua rau hauv cov khoom nqaij thiab saj.Qhov pom tseeb tshaj plaws yog nyob rau ntawm ob sab ntawm lub hauv paus ntawm tus nplaig, ua raws li cov ntsiab lus xws li crispness ntawm cov khoom saj;
3.4 Kev txiav txim siab ntawm PH tus nqi, PH8.0-9.0, muaj zog alkalinity heev, hnyav tenderization ntawm cov nqaij, ua rau cov khoom xoob, tsis ilv slices, tsis zoo elasticity;
3.5 Cov khoom sib xyaw ua ke muaj qhov tsw zoo thiab muaj txiaj ntsig zoo, zam qhov tsis zoo ntawm ib yam khoom xws li astringent tsw, tsis zoo solubility, ntsev los nag, thiab cov nyhuv insignificant;
