Thiab peb tuaj yeem tiv thaiv qhov kev pheej hmoo ntawm kev raug aflatoxin hauv lub neej niaj hnub li cas? Cov neeg sau xov xwm tau nrhiav kev txheeb xyuas txog cov teeb meem no.
"Frozen steamed buns tsis tsim aflatoxin nyob rau hauv ib txwm muaj, vim aflatoxin yog tsim los ntawm pwm xws li Aspergillus flavus nyob rau hauv high-temperature, high-humidity ib puag ncig. " hais tias Wu Jia, Tus Lwm Thawj Tuav Haujlwm ntawm Lub Tuam Txhab Saib Xyuas Khoom Noj Khoom Haus ntawm Tuam Txhab Txhawb Kev Noj Qab Haus Huv thiab Kev Kawm Txuj Ci. Yog tias cov buns steamed twb tau kis los ntawm pwm ua ntej khov, cov pwm co toxins yuav tsis raug tshem tawm txawm tias lawv khov.

Yog tias cov buns steamed muaj ntxhiab tsw txawv, hloov xim, lossis txawv txav tom qab thawing, lawv yuav tsum muab pov tseg kom tsis txhob noj.
Raws li "Kev Noj Qab Haus Huv thiab Kev Noj Qab Haus Huv," aflatoxin yog ib qho metabolite tsim los ntawm Aspergillus flavus thiab Aspergillus parasiticus, uas yog cov fungi hauv nplej thiab pub. Hauv Suav teb, Aspergillus parasiticus yog qhov tsawg. Qhov kub ntau rau Aspergillus flavus loj hlob thiab tsim aflatoxin yog 12 ° C txog 42 ° C, nrog rau qhov zoo tshaj plaws kub rau aflatoxin ntau lawm yog 25 ° C mus rau 33 ° C, thiab cov dej zoo tshaj plaws yog 0.93 txog 0.98.
Aflatoxin feem ntau yog tsim los ntawm cov pwm hauv qhov chaw sov thiab ntub. Kev ceev faj hauv lub neej txhua hnub tuaj yeem txo qhov kev pheej hmoo ntawm kev kis tus kab mob thiab noj aflatoxin. Cov kws tshaj lij pom zoo xaiv cov npe nrov thiab cov neeg muag khoom thaum yuav khoom noj kom ntseeg tau qhov tshiab thiab nyab xeeb.

Thaum lub sijhawm ua zaub mov thiab ua noj, cov zaub mov yuav tsum tau ntxuav kom huv si, thiab yuav tsum tau them nyiaj rau txoj kev ua noj.
Tsis tas li ntawd, vim qhov zoo thermal stability ntawm aflatoxin, nws tsis yooj yim decomposed los ntawm cov pa ua noj thiab cua sov. Cov zaub mov pwm yuav tsum tau zam, thiab txawm tias cov pwm raug tshem tawm, qhov seem yuav tsum tsis txhob noj.

Hais txog kev tshawb fawb txog kev khaws cia ntawm steamed buns, Wu Jia tau hais tias khov khov yog qhov kev xaiv zoo tshaj plaws thiab zoo tshaj plaws. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias steamed buns yuav tsum tau muab ntim rau hauv cov hnab ntim khoom noj lossis hnab yas kom tsis txhob sib cuag nrog huab cua, tiv thaiv dej evaporation, thiab tsis txhob muaj cov ntxhiab tsw. Steamed buns uas tsis kis kab mob tuaj yeem noj tsis pub dhau rau lub hlis yog tias khaws cia hauv qhov chaw khov hauv qab -18 ° C. Nyob rau hauv ib qho chaw txias, lawv tuaj yeem khaws cia rau ib mus rau ob hnub tab sis kuj yuav tsum tau muab kaw kom tsis txhob ya raws.
