1. Cov yam ntxwv ntawm Microbiological Risk Cov Khoom Noj Khoom Noj Zej Zog

Kev kis kab mob microbial yog qhov ua rau cov zaub mov lwj. Raws li National Food Safety Standard (GB 7101-2015), kab mob pathogenic (xws li,Salmonella, Staphylococcus aureus) yuav tsum tsis txhob raug kuaj pom hauv cov khoom noj, thaum qhov ntsuas kab mob xws li coliforms yuav tsum tswj tsis pub dhau qhov txwv. Txawm li cas los xij, cov khoom noj uas ze ze yuav ntsib cov kev pheej hmoo hauv qab no thaum khaws cia thiab thauj mus los:

1)Environmental Fluctuations:Kev hloov pauv hauv qhov kub thiab av noo tuaj yeem ua kom cov kab mob tsis muaj kab mob, ua kom lawv loj hlob sai. Piv txwv li, tom qab cov kab mob khaub thuas tawg, cov kab mob lactic acid suav hauv qee hom yogurt nce 50-fold hauv 24 teev, nrog rau cov pwm overgrowth.

2)Packing Failure:Cov dej ntws tawm hauv lub tshuab nqus tsev los yog kev puas tsuaj ntawm cov tshuaj tua kab mob tuaj yeem ua rau muaj kab mob aerobic.

3)Hla-Contamination:Kev sib xyaw cov khoom tshiab nrog cov zaub mov ntim ua ntej ntawm cov khw muag khoom tuaj yeem qhia txog cov kab mob exogenous.

2. Cov xwm txheej tam sim no tau nthuav tawm los ntawm kev sim cov ntaub ntawv

Ib qho 2024 thib peb-tog sampling kev soj ntsuam ntawm cov khoom noj uas yuav nyob ze ntawm lub khw tau qhia:

Kev Tsim Nyog Rate:92.3% ntawm cov qauv ua tau raws li cov qauv microbiological, tab sis qhov no sawv cev rau 4.7% poob qis piv rau thawj lub sijhawm txee lub neej.

Pawg Risk Siab:

1) Cov khoom noj uas muaj dej noo (piv txwv li, cov zaub mov npaj txhij, cov khoom noj siv mis): 7% ntawm cov qauv muaj tag nrho cov kab mob suav txog kev txwv.

2) Cov khoom noj uas tsis muaj kua qaub (piv txwv li, qhob cij, pastries): 3% kuaj pom zoo rau mycotoxins.

Tej teeb meem:Qee cov khoom noj khoom haus uas ze ze tshaj plaws tau nthuav tawm cov kab mob microbiological overgrowth vim tsis tiav daim ntawv lo txhais lus, ua rau muaj kev cia khoom tsis raug.

3. Scientific Logic Tom Qab Kev Txiav Txim Siab

Khoom noj khoom haus txee-lub neej tsis yog ib qho yooj yim "kev nyab xeeb-kev phom sij" tab sis yog ib qho kev saib xyuas kev kwv yees raws li kev ntsuas ceev ceev-lub neej (ASLT). Piv txwv li:

Cov khoom siv mis nyuj:Ntawm 4 ° C, txee lub neej feem ntau yog teem rau ntawm 60% ntawm lub sij hawm xav tau rau tag nrho cov kab mob suav kom ncav cuag cov kev txwv.

Puffed Khoom txom ncauj:Thaum cov dej ua haujlwm yog <0.6, qhov kev pheej hmoo microbiological tsawg tsawg, thiab lub neej txee yog txiav txim siab feem ntau los ntawm kev txhawj xeeb ntawm lipid oxidation.
Qhov no qhia tau hais tias cov khoom noj uas yuav luag tas yuav raug muab khaws cia rau hauv cov xwm txheej raws li txoj cai muaj kev nyab xeeb, txawm tias qhov kev pheej hmoo ntawm marginal maj mam nce.

4. Kev Sib Tw Kev Lag Luam thiab Kev Txhim Kho Cov Tswv Yim

Cov kev sib tw uas twb muaj lawm

1)Gap hauv Supply Chain Monitoring:Kwv yees li ntawm 35% ntawm cov khw muag khoom tsis muaj lub siab kub-tswj tshuab rau cov khoom noj uas ze ze.

2)Yav dhau los Test Technologies:Cov txheej txheem kab lis kev cai ib txwm xav tau 48 teev rau cov txiaj ntsig, ua rau lawv tsis tsim nyog rau kev xa tawm sai.

3)Tsis txaus Standard Refinement:Cov qauv hauv teb chaws tam sim no tsis muaj qhov sib txawv ntawm microbiological txwv rau cov khoom noj uas ze ze.

Optimization Cov lus pom zoo

1)Tsim kom muaj Dynamic Monitoring Systems:

1. Txhawb nqa ATP bioluminescence nrhiav tshuab rau kev sim sai ntawm qhov chaw (30-feeb tau).
2. Siv blockchain thev naus laus zis los taug qab cov ntaub ntawv khaws cia ib puag ncig.

2)Txhim kho Standardization:

1. Qhia ntxiv qhov yuav tsum tau kuaj xyuas rau pawg uas muaj kev pheej hmoo siab thaum lub sij hawm ze-kawg.
2. Txais yuav txoj kev tswj hwm qib raws li EU Txoj Cai (EC) Tsis Muaj 2073/2005, raws li kev cia khoom.

3)Txhim khu kev kawm rau cov neeg siv khoom:

1. Tso cov ntawv tshaj tawm hauv lub sijhawm sim ntawm QR cov lej ntawm kev ntim khoom.
2. Qhia rau cov neeg siv khoom ntawm "kev txiav tawm tam sim ntawd thaum muaj qhov txawv txav."

5. Cov lus xaus thiab Outlook

Cov ntaub ntawv tam sim no qhia tau hais tias cov khoom noj khoom haus uas tau txais kev tswj hwm zoo nyob ze yuav muaj kev ua raws li microbiological siab, tab sis kev pheej hmoo ntawm cov khoom siv saw hlau yuav tsum tau ceev faj. Nws raug nquahu kom tsim kom muaj kev sib koom tes tswj hwm kev pheej hmoo nrog cov neeg tsim khoom, cov neeg xa khoom, thiab cov tswj hwm, nrog rau kev nce qib sai sai thiab kev ua kom zoo dua qub. Saib tom ntej, kev txais yuav cov ntim khoom ntse (xws li, lub sijhawm ntsuas kub) yuav ua kom muaj kev tswj hwm zoo dua thiab muaj txiaj ntsig zoo rau cov khoom noj uas ze ze.
