Scientz Pab Kev Tshawb Nrhiav Cov Tshuaj Tua Kab Tsuag hauv Cov Khoom Noj Khoom Noj

Scientzpab tshawb nrhiav cov tshuaj tua kab uas nyob hauv cov zaub mov uas tau cog qoob loo

Cov khoom noj cog qoob loo muab rau tib neeg lub cev nrog lub zog thiab cov khoom noj uas xav tau los ntawm lub cev, thiab yog ib qho tseem ceeb ntawm cov khoom muaj sia nyob. Nyob rau hauv xyoo tas los no, cov teeb meem kev nyab xeeb khoom noj tau tshwm sim ntau zaus hauv kuv lub tebchaws, cov teeb meem ntawm cov tshuaj tua kab yog qhov tseem ceeb, uas tau nyiam cov neeg tuaj saib thoob plaws hauv lub neej. Ntau yam tshuaj tua kab yog qhov nyuaj rau degrade sai heev nyob rau hauv tej yam ntuj tso vim lawv ruaj khov tshuaj. Kev noj cov tshuaj tua kab ntev ntev yuav ua rau muaj kev phom sij loj rau tib neeg lub cev thiab ua rau lub neej thiab kev noj qab haus huv. Kev tshawb nrhiav cov tshuaj tua kab nyob hauv cov khoom noj uas tau txais los ntawm cov nroj tsuag yog ib qho teeb meem uas tsis tuaj yeem zam los ntawm kev xav txog kev nyab xeeb ntawm zaub mov. Nws yog ib qho tsim nyog los xyuas kom meej tias cov tshuaj tua kab nyob hauv cov khoom noj uas tau txais los ntawm cov nroj tsuag tau raws li cov qauv kev nyab xeeb hauv tebchaws.

Tam sim no, feem ntau siv cov hau kev rau kev kuaj pom ntawm cov zaub mov muaj tshuaj xws li cov zaub mov muaj xws li Ramas, thiab ua kom zoo nkauj. Ntawm lawv, vim nws txoj kev loj hlob thaum ntxov, chromatographic nrhiav kom tau thev naus laus zis tau paub tab thiab zoo tag nrho, suav nrog roj chromatography, kua chromatography, LC-MS, GC-MS thiab lwm yam thev naus laus zis kom tau raws li qhov xav tau ntawm kev tshawb nrhiav tshuaj tua kab ntau. Kev tshawb nrhiav lub teb chaws tshiab ntawm cov tshuaj tua kab nyob hauv cov khoom noj cog qoob loo siv cov kua theem-mass spectrometry raws li txoj kev tshawb nrhiav.

Lub teb chaws tus qauv tshiab rau cov tshuaj tua kab residue GB23200

Kev tshawb nrhiav cov qauv khoom noj uas tau los ntawm cov nroj tsuag yuav tsum tau muaj kev soj ntsuam siab thiab kev kuaj pom, thiab yuav ua li cas thiaj li kho tau cov qauv ua ntej yog qhov tseem ceeb tshwj xeeb. Cov txheej txheem pretreatment zoo tuaj yeem tsis tsuas yog txuag lub sijhawm thiab kev siv zog, tab sis qhov tseem ceeb tshaj, nws tuaj yeem txhim kho qhov ua tau zoo ntawm kev rho tawm cov qauv tom ntej, thiab txhim kho qhov tseeb thiab sib xws ntawm kev tshuaj xyuas thiab kev tshawb pom.

Cov txheej txheem sib txawv yog siv rau cov khoom sib txawv:

1. Cov txiv hmab txiv ntoo noj tau, cov txiv hmab txiv ntoo thiab cov txiv hmab txiv ntoo, cov zaub hauv dej, cov zaub qia, legumes, txiv hmab txiv ntoo pob zeb, cov txiv hmab txiv ntoo thiab cov txiv hmab txiv ntoo, cov txiv hmab txiv ntoo thiab zaub yog pre-kho los ntawm thawj chopping thiab ces homogenizing cov qauv. Nco tseg: qhuav zaub, txiv hmab txiv ntoo thiab cov nceb noj tau hauv av thiab crushed

2. Tom qab cov cereals hauv av thiab pulverized, tag nrho cov ntawm lawv tau ua tiav los ntawm tus qauv mesh npo ntawm 425 μm.

3. Sib tsoo thiab crushing ntawm roj, tshuaj yej, txiv ntseej thiab txuj lom (seasoning).

4. Cov roj zaub yog tusyees nplawm thiab ua tiav. Cov qauv ua tiav yog raug rau tom qab rho tawm thiab centrifugation, thiab tom qab pom, cov qauv thauj khoom kuaj pom tau ua tiav.
