Tsis ntev los no, lub ncauj lus ntawmav aflatoxinLoj hlob ntawm cov brozing ua kom sov buns tom qab tau khaws cia ntau tshaj ob hnub tau ua rau pej xeem txhawj xeeb. Puas yog nws muaj kev nyab xeeb kom haus cov buns buns? Yuav ua li cas yuav tsum cov buns yuav muab cov kev tshawb fawb? Thiab yuav ua li cas peb thiaj tiv thaiv kev pheej hmoo ntawm AFLatoxin raug nyob rau hauv lub neej txhua hnub? Cov neeg tshaj xo tau tshawb nrhiav cov teeb meem ntawm cov teeb meem no.
"Flozen buns tsis tsim aflatoxin nyob rau hauv ib txwm muaj tshwm sim los ntawm benavgillus nyob ib puag ncig (nyob ib ncig ntawm -18 ° C) tsis zoo rau kev loj hlob rau pwm loj hlob, "Said Wu Jia, Tus Lwm Thawj Decretary-General ntawm Kev Paub Zoo Kev Kawm Lus Ceg Lus thiab Koom Haum Kev Kawm Ntawv. Yog hais tias cov bubed buns twb tau paug los ntawm pwm ua ntej khov, pwm co txhuas yuav tsis raug tshem tawm txawm tias lawv khov. Yog li ntawd, khov beamed buns uas yog tshiab thiab tsis tau ua ua ntej khov yuav tau noj nrog kev ntseeg siab. Yog hais tias cov buns muaj cov ntxhiab tsw txawv, xim hloov, lossis txawv txawv tom qab yaj, lawv yuav tsum muab pov tseg kom tsis txhob noj.
Raws li "khoom noj khoom haus thiab cov khoom noj kom huv," Aflatoxin yog cov metabolite tsim los ntawm aspergillus flavus thiab aspergillus patasiticus, uas yog cov nquag forgi hauv lis thiab pub. Hauv Suav teb, aspergillus parasiticus yog qhov tsawg. Kev ntsuas kub rau aspergillus flavus kom loj hlob thiab tsim cov dej sflatoxin yog 12 ° C, nrog cov dej ua haujlwm zoo tshaj plaws yog 0.93 mus rau 0.98.
Aflatoxin tsuas yog tsim los ntawm cov pwm hauv cov chaw sov thiab noo noo. Kev ceev faj hauv lub neej txhua hnub tuaj yeem txo cov kev pheej hmoo ntawm kev raug mob thiab noj ntawm aflatoxin. Cov kws tshaj lij pom zoo xaiv cov npe nrov nrov thiab cov muag khoom thaum yuav khoom noj kom paub tseeb thiab kev nyab xeeb. Thaum khaws cia zaub mov, kev saib xyuas yuav tsum tau them rau lub txee txee, thiab cov khoom noj kom zoo kom txo tau lub sijhawm rau kev loj hlob pwm.

Tsis tas li ntawd, vim yog qhov zoo thermal stability ntawm aflatoxin, nws tsis yooj yim decomposed los ntawm kev ua noj ua haus thiab cua sov. Mouldy cov zaub mov yuav tsum tau zam, thiab txawm tias cov pwm feem raug tshem tawm, tus so yuav tsum tsis txhob noj. Ib qho ntxiv, kev muaj kev nyab xeeb yuav tsum tau txhim kho, thiab cov tais diav hauv chav ua noj xws li kev tiv thaiv kom tsis txhob muaj pwm thiab cov kab mob.

Steamed buns uas tsis tau paug los ntawm pwm tuaj yeem noj tau nyob rau hauv rau lub hlis yog muab tso rau hauv ib puag ncig khov hauv qab-18 ° C. Nyob rau hauv ib puag ncig tub yees, lawv tuaj yeem khaws cia rau ib mus rau ob hnub tab sis kuj yuav tsum tau muab ntim kom tsis txhob ya raws.
