Ntxivphosphates rau cov khoom siv nqaij tuaj yeem txhim kho qhov kev ntxhib los mos ntawm cov khoom, ua kom cov dej tuav thiab cov khoom lag luam tawm ntawm cov khoom, thiab txhim kho kev ntxhib los mos ntawm cov khoom nqaij, yog li txo tus nqi ntawm cov khoom tsis txo cov khoom zoo. (1) Ua kom cov pH nqi ntawm cov nqaij; (2) Chelate hlau ions hauv nqaij; (3) Ua kom lub zog ionic ntawm cov nqaij; (4) Dissociate actomyosin.
Tripolyphosphate thiab pyrophosphate tuaj yeem ua rau kom muaj zog ionic ntawm cov nqaij nruab deg los ntawm kev hloov cov hluav taws xob muaj peev xwm ntawm cov protein, thiab ua kom nws deviate los ntawm isoelectric point, kom cov nqi sib tw thiab tsim qhov chaw loj ntawm cov protein, uas yog, cov protein "so" ntawm cov nqaij nqaij tuaj yeem muaj dej ntau ntxiv los txhim kho cov dej tuav; hexametaphosphate tuaj yeem chelate hlau ions, txo kev sib xyaw ntawm cov hlau ions thiab dej, thiab ua kom cov protein khi dej ntxiv los txhim kho dej tuav. Kev xyaum tau ua pov thawj tias kev sib xyaw siv ntau yamphosphates yog zoo dua li siv ib zaug, yog li sib xyawphosphates feem ntau yog siv los ua kom cov nyhuv. Lub compoundphosphate yog alkaline, uas tuaj yeem nce pH tus nqi ntawm cov nqaij thiab txhawb kev sib tw ntawm calcium activating enzyme ntawm cov nqaij. Nyob rau tib lub sij hawm, lub compositephosphate muaj cov nqi tsis zoo ntau dua, thiab qis dua ntawm cov khoom sib xyawphosphate tuaj yeem ua kom muaj zog ionic ntawm cov tshuaj, yog li nws tuaj yeem chelate hlau ions, xws li magnesium, zinc, thiab lwm yam, thiab nthuav tawm cov protein-COO-terminal Txhim kho cov electrostatic repulsion ntawm cov nqaij, relaxes cov nqaij, thiab ua rau kom cov rhiab heev. ntawm cov nqaij.
Txij li thaum rhiab heev ntawm cov nqaij muaj feem xyuam rau cov ntsiab lus ntawm cov ntaub so ntswg thiab myofibril, qhov ntau collagen cross-links nyob rau hauv cov ntaub so ntswg, qhov hnyav ntawm cov nqaij. Tom qab ntxiv cov phosphate complex, nws muaj peev xwm ua rau kom lub solubility ntawm collagen, txo qhov cross-linking ntawm collagen nyob rau hauv cov ntaub so ntswg, thiab txhim kho cov rhiab ntawm nqaij.
Compound phosphate Kuj tseem tuaj yeem cuam tshuam cov actomyosin, txo cov leeg nqaij, thiab txhim kho nqaij rhiab. Qhov ratio ntawm compoundphosphate yog: tripolyphosphate: pyrophosphate: hexametaphosphate-2: 2: 1, thiab thaum qhov sib ntxiv yog 0.5%, cov nyhuv tenderization ntawm nqaij nyuj thiab luav nqaij yog qhov zoo tshaj plaws. Nws raug nquahu kom siv cov tshuaj marinating rau 16 teevphosphate decomposing enzyme nyob rau hauv nqaij cov khoom decomposesphosphate thiab ua rau nws tsis muaj txiaj ntsig. Yog li ntawd, nyob rau hauv cov txheej txheem ntawm cov khoom siv nqaij, tshwj xeeb yuav tsum tau them nyiaj rau kev xaiv ntawm cov txheej txheem tsim nyog ntxiv kom tsis txhob rhuav tshem cov nyhuv ntawmphosphate. Feem ntau, hauv kev tsim thiab ua cov khoom siv nqaij, feem ntau nws yog qhov zoo tshaj plaws los siv nws hauv dov thiab sib tov tom qab marinating; Kuj tseem muaj txoj hauv kev siv cov tshuaj marinating. Nyob rau tib lub sijhawm, nws raug txiav txim siab tias qhov sib ntxiv ntawm phosphate ntau dhau yuav ua rau qhov tsw thiab xim ntawm cov khoom tsis zoo, thiab tsis zoo rau tib neeg kev noj qab haus huv.
Kev nyab xeeb ntawmphosphate:
Phosphate yog ib qho tseem ceeb ntawm tib neeg cov ntaub so ntswg, xws li cov hniav, pob txha thiab enzymes, thiab plays lub luag hauj lwm tseem ceeb thiab indispensable nyob rau hauv lub metabolism ntawm cov as-ham tseem ceeb xws li qab zib, rog, thiab proteins. Yog li ntawd,phosphate feem ntau yog siv los ua khoom noj khoom haus fortifier. Tab sis thaum lubphosphate cov ntsiab lus nyob rau hauv cov khoom noj yog ntau dhau lawm, nws yuav txo qhov nqus ntawm calcium, ua rau poob ntawm calcium nyob rau hauv tib neeg cov pob txha cov ntaub so ntswg. Yog tias nws kav ntev, nws tuaj yeem ua rau kev loj hlob qeeb thiab pob txha deformities. Yog li ntawd, phosphates yuav tsum tau ntxiv thiab siv nruj me ntsis raws li kev siv tau teev tseg los ntawm lub xeev.

"Peb lub tuam txhab tsuas yog siv los ua kev lag luam hauv tsev xwb. Nrog rau kev qhia txog cov kev cai zoo xws li kev ua lag luam thiab kev lag luam, tam sim no lub tuam txhab cov khoom xa tawm mus rau 1/3 ntawm tag nrho cov khoom tsim tawm." Zhang Jie, tus thawj coj ntawm Linyi Youyou Tsev Khoom Co., Ltd. hais rau cov neeg sau xov xwm, Linyi Mall Ntau tus tub lag luam tsom mus rau kev muag khoom hauv tsev tau pib ua siab tawv los qhib kev lag luam txawv teb chaws.
Cov txiaj ntsig zoo ntawm txoj cai-taw qhia "tawm mus" ntawm kev lag luam yog "blooming" hauv thaj av Qilu. Thaum Lub Kaum Ib Hlis 12, SCO Demonstration Zone Certificate of Origin Examination thiab Kos Npe Chaw tau raug qhib hauv Qingdao, xeev Shandong. Lub chaw yog tus cwj pwm los ntawm kev pabcuam kev lag luam thiab kev lag luam kev koom tes ntawm SCO cov tswvcuab hauv lub xeev, tso cai rau cov khoom lag luam Suav tsim nyog tau txais kev nyiam tariff thaum lawv raug xa tawm.
"Kev koom ua ke rau hauv kev tsim kho ntawm 'Belt thiab Road' tau muab cov tswv yim tshiab rau Shandong txoj kev lag luam txawv teb chaws thiab qhib kev lag luam tshiab." Zheng Shilin, tus kws tshawb fawb ntawm lub koom haum ntawm Quantitative thiab Technical Economics ntawm Suav Academy ntawm Social Sciences.
