Puas yog Tricalcium Phosphate muaj kev phom sij?

Puas yog Tricalcium Phosphate txaus ntshai?

** Taw qhia

Tricalcium phosphate (TCP) yog qhov sib xyaw ua ke uas tau txais txiaj ntsig zoo vim nws cov kev siv ntau yam hauv ntau lub lag luam, suav nrog zaub mov thiab dej haus, tshuaj, tshuaj pleev ib ce, thiab kev ua liaj ua teb. Txawm li cas los xij, zoo li txhua yam tshuaj lom neeg, muaj kev txhawj xeeb txog nws qhov muaj peev xwm txaus ntshai thiab cuam tshuam txog kev nyab xeeb. Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov xwm txheej ntawm tricalcium phosphate, nws txoj kev siv, thiab tshuaj xyuas nws cov ntaub ntawv kev nyab xeeb raws li cov pov thawj scientific muaj.

Tricalcium Phosphate yog dab tsi?

Tricalcium phosphate, tseem paub los ntawm nws cov tshuaj formula Ca3(PO4)2, yog cov hmoov dawb, tsw tsw. Nws tshwm sim nyob rau hauv ntau hom, suav nrog apatite, ib qho ntxhia hauv pob zeb thiab pob txha tshauv. TCP feem ntau yog tsim los ntawm cov tshuaj tiv thaiv ntawm calcium hydroxide thiab phosphoric acid los yog kho calcium phosphate pob zeb nrog sulfuric acid.

Kev siv Tricalcium Phosphate

TCP pom cov ntawv thov dav hauv ntau qhov kev lag luam. Qee qhov kev siv tseem ceeb yog:

1. Kev lag luam khoom noj khoom haus thiab dej haus: TCP yog dav siv los ua khoom noj khoom haus thiab khoom noj khoom haus ntxiv. Nws feem ntau pom muaj nyob rau hauv cov khoom siv mis nyuj, khoom ci, dej haus, thiab noj tshais cereals. TCP ua raws li cov kua qaub regulator, anti-caking agent, thiab calcium ntxiv nyob rau hauv cov khoom no. Nws feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm cov tswj hwm kev tswj hwm thaum siv raws li kev tsim khoom zoo.

2. Pharmaceutical Industry: TCP yog siv los tsim cov tshuaj xws li tshuaj antacids thiab calcium ntxiv. Nws muab ib qhov chaw ntawm calcium thiab phosphorus, pab rau cov pob txha noj qab haus huv ntawm cov neeg mob. Cov tshuaj-qib TCP tau dhau los kuaj nruj thiab tswj kom zoo kom ntseeg tau tias nws muaj kev nyab xeeb thiab ua haujlwm tau zoo.

3. Kev lag luam tshuaj pleev ib ce: TCP yog siv rau hauv ntau yam tshuaj pleev ib ce thiab cov khoom siv tu tus kheej vim nws cov khoom nqus thiab abrasive. Nws tuaj yeem pom hauv cov tshuaj txhuam hniav, tshuaj ntxuav lub ntsej muag, thiab exfoliators. Cov tshuaj pleev ib ce muaj TCP raug soj ntsuam kev nyab xeeb kom ntseeg tau tias muaj kev nyab xeeb rau cov neeg siv khoom.

4. Kev Lag Luam Kev Ua Liaj Ua Teb: TCP yog siv los ua chiv vim nws cov ntsiab lus phosphorus siab. Nws muab cov zaub mov tseem ceeb rau cov qoob loo thiab txhawb kev loj hlob ntawm cov nroj tsuag noj qab haus huv. Cov neeg ua liaj ua teb ua tib zoo ua raws li cov lus qhia siv TCP kom nyab xeeb thiab ua tau zoo.

Kev xav txog kev nyab xeeb

Ua ntej txiav txim siab txog kev nyab xeeb ntawm tricalcium phosphate, nws yog ib qho tseem ceeb rau kev sib txawv ntawm cov ntawv sib txawv thiab kev siv ntawm TCP.

1. Khoom noj khoom haus-Qib Tricalcium Phosphate: TCP siv nyob rau hauv kev lag luam khoom noj khoom haus thiab dej haus yuav tsum ua raws li cov kev cai nruj tswj xyuas kom nws muaj kev ruaj ntseg rau noj. Cov cai tswj hwm, xws li Food and Drug Administration (FDA) hauv Tebchaws Meskas thiab European Food Safety Authority (EFSA) hauv Tebchaws Europe, tau teeb tsa siab tshaj plaws ntawm TCP hauv ntau yam khoom noj. Cov kev txwv no yog ua raws li kev tshawb fawb toxicological thiab kev soj ntsuam ntau.

rau ntu tom ntej, TCP txoj kev nyab xeeb yuav tau tham txog ntau yam:**

Kev ntsuas tshuaj toxicity thiab exposure **

Ntau yam kev tshawb fawb tau tshuaj xyuas cov teebmeem toxicological ntawm tricalcium phosphate thiab tshuaj xyuas nws cov ntaub ntawv kev nyab xeeb. Nov yog qee qhov kev tshawb pom tseem ceeb ntawm cov kev tshawb fawb no:

1. Mob toxicity: Mob toxicity yog hais txog cov teebmeem tshwm sim sai tom qab ib zaug raug rau ib yam khoom. Cov kev tshawb fawb tsis tu ncua tau pom tias tricalcium phosphate yog cov tshuaj lom neeg tsawg. Kev tshaj tawm qhov koob tshuaj nruab nrab (LD50) rau qhov ncauj qhov ncauj hauv nas yog feem ntau ntau dua 2000 mg / kg lub cev hnyav. Qhov no qhia tau hais tias kev noj TCP, txawm tias ntau npaum li cas, tsis ua rau muaj kev pheej hmoo rau kev noj qab haus huv tam sim ntawd.

2. Chronic Toxicity: Chronic toxicity yog hais txog qhov cuam tshuam ntev ntawm kev rov raug tshuaj rau ib yam khoom. Ntau qhov kev tshawb fawb tsiaj tau tshawb xyuas qhov mob toxicity ntawm TCP, thiab tsis muaj qhov cuam tshuam loj heev tau pom. Hauv cov kev tshawb fawb uas tsiaj tau pub TCP raws li ib qho chaw ntawm calcium thiab phosphorus rau lub sijhawm ntev, tsis muaj kev cuam tshuam rau kev noj qab haus huv tau tshaj tawm.

3. Genotoxicity: Genotoxicity yog hais txog lub peev xwm ntawm ib yam khoom los ua kom puas genetic khoom. Ntau cov kev tshawb fawb genotoxicity ua los ntawm tricalcium phosphate tsis pom muaj pov thawj ntawm DNA puas lossis cov teebmeem mutagenic.

4. Carcinogenicity: Cov kev tshawb fawb Carcinogenicity ntsuam xyuas lub peev xwm ntawm ib yam khoom los ua rau kev loj hlob ntawm qog nqaij hlav. Muaj cov kev tshawb fawb ntawm TCP tau pom tsis tu ncua tias nws tsis yog carcinogenic.

5. Kev loj hlob thiab kev loj hlob toxicity: Kev tshawb fawb soj ntsuam cov teebmeem ntawm TCP ntawm kev loj hlob thiab kev loj hlob tsis tau pom tias tsis muaj kev cuam tshuam loj heev. TCP suav tias yog kev nyab xeeb rau cov poj niam cev xeeb tub thiab menyuam yaus.

6. Kev Tshaj Tawm Txog Kev Ua Haujlwm: Cov neeg ua haujlwm nrog tricalcium phosphate, xws li cov hauv kev tsim khoom, tej zaum yuav raug ntau dua li cov pej xeem. Kev ntsuas kev nyab xeeb ntawm kev ua haujlwm, xws li kev siv cov cuab yeej tiv thaiv tus kheej thiab kev tswj xyuas engineering, yog siv los txo cov kev pheej hmoo tsawg.

7. Kev Nyab Xeeb Ib puag ncig: Tricalcium phosphate tsis ua rau muaj kev phom sij loj. Nws yog biodegradable, thiab nws siv hauv kev ua liaj ua teb pab txhawb rau lub voj voog khoom noj hauv av. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov lus pom zoo kom tsis txhob muaj dej ntau dhau los yog cov dej paug hauv lub cev.

Xaus

Raws li cov pov thawj scientific muaj, tricalcium phosphate feem ntau suav hais tias muaj kev nyab xeeb rau nws ntau yam kev siv, suav nrog zaub mov thiab dej haus, tshuaj, tshuaj pleev ib ce, thiab kev ua liaj ua teb. Cov cai tswj hwm thoob ntiaj teb tau tsim cov txheej txheem nruj thiab qib siab tso cai kom ntseeg tau tias nws muaj kev nyab xeeb siv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov kev coj ua thiab cov lus qhia kom txo qis kev pheej hmoo cuam tshuam nrog rau TCP. Cov tib neeg ua haujlwm nrog tricalcium phosphate yuav tsum tau ua raws li kev ntsuas kev nyab xeeb tsim nyog los tiv thaiv kev ua haujlwm raug mob. Raws li nrog rau txhua yam tshuaj lom neeg, kev tshawb fawb thiab kev soj ntsuam txuas ntxiv yog tsim nyog los xyuas kom meej tias nws muaj kev nyab xeeb txuas ntxiv mus rau ntau yam kev lag luam.
