1. Zowopsa za Microbiological Risk of Near-Expiry Foods

Kuwonongeka kwa tizilombo ndizomwe zimayambitsa kuwonongeka kwa chakudya. Malinga ndi National Food Safety Standard (GB 7101-2015), mabakiteriya oyambitsa matenda (mwachitsanzo,Salmonella, Staphylococcus aureus) sayenera kuzindikirika muzakudya, pomwe tizilombo tating'onoting'ono monga ma coliforms tiyenera kuwongolera mkati mwa malire odziwika. Komabe, zakudya zomwe zatsala pang'ono kutha zimatha kukumana ndi zovuta zotsatirazi panthawi yosungira ndi kunyamula:

1)Kusinthasintha Kwachilengedwe:Kusiyanasiyana kwa kutentha ndi chinyezi kungayambitse tizilombo tating'onoting'ono tating'ono, ndikufulumizitsa kuchuluka kwawo. Mwachitsanzo, pambuyo pa unyolo wozizira wosweka, mabakiteriya a lactic acid amawerengera mumtundu wina wa yogati adakwera 50 mkati mwa maola 24, motsatizana ndi kukula kwa nkhungu.

2)Kukanika Kulephera:Kutayikira mu vacuum phukusi kapena kuwonongeka kwa zoteteza kungayambitse kuphulika kwa mabakiteriya a aerobic.

3)Kuipitsidwa:Kusakaniza zokolola zatsopano ndi zakudya zomwe zidasungidwa kale m'malo ogulitsira kumatha kuyambitsa tizilombo toyambitsa matenda.

2. Mkhalidwe Wamakono Wowululidwa ndi Kuyesa Data

Kuwunika kwachipani cha 2024 kwazakudya zomwe zatsala pang'ono kutha pamsika zidawululidwa:

Mlingo Woyenerera:92.3% ya zitsanzo zinakwaniritsa miyezo ya microbiological, ngakhale izi zimayimira kuchepa kwa 4.7% poyerekeza ndi nthawi yoyambira ya alumali.

Magulu Owopsa Kwambiri:

1) Zakudya zokhala ndi chinyezi chambiri (mwachitsanzo, zakudya zokonzeka kudyedwa, mkaka): 7% ya zitsanzo zinali ndi kuchuluka kwa mabakiteriya omwe akuyandikira malire owongolera.

2) Zakudya zopanda asidi (monga mkate, makeke): 3% adapezeka ndi mycotoxins.

Zomwe Zachitika:Zakudya zina zomwe zatulutsidwa kunja zomwe zatsala pang'ono kutha zikuwonetsa kuchulukirachulukira kwa tizilombo toyambitsa matenda chifukwa cha kusakwanira kwa matanthauzidwe, zomwe zidapangitsa kuti kusungidwe kosayenera.

3. Malingaliro Asayansi Kuseri kwa Kutsimikiza kwa Shelf-Moyo

Moyo wa alumali lazakudya si njira yosavuta "yowopsa" koma kulosera kokhazikika kutengera kuyesa kwa moyo wa alumali (ASLT). Zitsanzo ndi izi:

Zamkaka:Pa 4 ° C, moyo wa alumali umayikidwa pa 60% ya nthawi yofunikira kuti chiwerengero chonse cha mabakiteriya chifikire malire olamulira.

Zokhwasula-khwasula:Ntchito yamadzi ikafika <0.6, kuwopsa kwa microbiological kumakhala kochepa, ndipo moyo wa alumali umatsimikiziridwa makamaka ndi nkhawa za okosijeni wamafuta.
Izi zikusonyeza kuti zakudya zomwe zatsala pang'ono kutha zomwe zimasungidwa m'mikhalidwe yovomerezeka zimakhalabe zotetezeka, ngakhale kuti zowopsa zimawonjezeka pang'onopang'ono.

4. Mavuto a Makampani ndi Njira Zowongola

Mavuto Amene Alipo

1)Mipata mu Kuwunika kwa Supply Chain:Pafupifupi 35% ya ogulitsa alibe machitidwe odzipereka oletsa kutentha kwa zakudya zomwe zatsala pang'ono kutha.

2)Matekinoloje Oyesa Akale:Njira zachikhalidwe zachikhalidwe zimafuna maola a 48 kuti apeze zotsatira, zomwe zimapangitsa kuti zikhale zosayenera kuti zigawidwe mofulumira.

3)Kusakwanira kwa Standard Refinement:Miyezo yapano ya dziko ilibe malire osiyanitsidwa ndi ma microbiological pazakudya zomwe zatsala pang'ono kutha.

Kukhathamiritsa Malangizo

1)Khazikitsani Njira Zowunikira Mphamvu:

1. Limbikitsani ukadaulo wozindikira za ATP bioluminescence poyesa mwachangu pamalopo (zotsatira za mphindi 30).
2. Gwiritsani ntchito ukadaulo wa blockchain kuti mufufuze deta yosungira chilengedwe.

2)Limbikitsani Standardization:

1. Yambitsani zofunikira zoyeserera zamagulu omwe ali pachiwopsezo chachikulu panthawi yomwe nthawi yake yatsala pang'ono kutha.
2. Landirani njira yoyang'anira ya tiered yolozera Malamulo a EU (EC) No 2073/2005, kutengera momwe amasungira.

3)Limbitsani Maphunziro a Ogula:

1. Onetsani malipoti anthawi yeniyeni yoyeserera kudzera pamakhodi a QR pamapaketi.
2. Phunzitsani ogula za "kusiya nthawi yomweyo pazovuta zamaganizo."

5. Mapeto ndi Outlook

Zomwe zilipo pano zikuwonetsa kuti zakudya zosamalidwa bwino zomwe zatsala pang'ono kutha zimasunga ziwopsezo zazikulu zotsatiridwa ndi tizilombo tating'onoting'ono, komabe zoopsa pamachitidwe operekera zakudya zimafunikira kukhala tcheru. Ndikofunikira kuti pakhale njira yogwirira ntchito yoyang'anira zoopsa yomwe ikukhudza opanga, ogawa, ndi owongolera, limodzi ndi kupititsa patsogolo matekinoloje oyesa mwachangu komanso kukonzanso koyenera. Kuyang'ana m'tsogolo, kukhazikitsidwa kwa ma CD anzeru (mwachitsanzo, zizindikiro za kutentha kwa nthawi) kumathandizira kuwongolera bwino komanso koyenera kwa zakudya zomwe zatsala pang'ono kutha.
