1. Izimpawu Zengcuphe Ye-Microbiological Yokudla Okuseduze Nokuphelelwa yisikhathi

Ukungcoliswa kwamagciwane kuyimbangela enkulu yokonakala kokudla. Ngokwe-National Food Safety Standard (GB 7101-2015), amagciwane e-pathogenic (isb,I-Salmonella, i-Staphylococcus aureus) akumele itholwe ekudleni, kuyilapho ama-microorganisms ayinkomba njengama-coliform kufanele alawulwe ngaphakathi kwemikhawulo ethile. Kodwa-ke, ukudla okuphelelwa yisikhathi kungase kubhekane nezingozi ezilandelayo phakathi nokugcinwa nokuthutha:

1)Ukushintshashintsha kwemvelo:Ukwehluka kwezinga lokushisa nomswakama kungase kusebenze ama-microorganisms alele, kusheshise ukwanda kwawo. Isibonelo, ngemva kokuphuka kweketango elibandayo, inani lamagciwane e-lactic acid ohlotsheni oluthile lweyogathi lenyuke ngokuphindwe ka-50 phakathi namahora angu-24, lihambisana nokukhula kwesikhunta.

2)Ukuhluleka Kwephakheji:Ukuvuza ekufakweni kwe-vacuum noma ukuwohloka kwezivimbelakuvunda kungase kuholele ekuqubukeni kwebhaktheriya ye-aerobic.

3)Ukungcoliswa okuphambene:Ukuxuba imikhiqizo emisha nokudla osekupakishwe ngaphambilini ezitolo kungase kungenise amagciwane angaphandle.

2. Isimo Samanje Sembulwa Ngokuhlola Idatha

Ukuhlolwa kwesampula kwango-2024 okuvela eceleni kokudla okuseduze nokuphelelwa yisikhathi emakethe kwembulwe:

Izinga lokufaneleka:Amasampula angu-92.3% ahlangabezane namazinga e-microbiological, nakuba lokhu kumelele ukwehla ngo-4.7% uma kuqhathaniswa nezikhathi zokuqala zeshelufu.

Izigaba ezinobungozi obukhulu:

1) Ukudla okunomswakama ophezulu (isb., ukudla osekulungele ukudliwa, imikhiqizo yobisi): Amaphesenti angu-7 amasampula ayenenani eliphelele lebhaktheriya elisondela emikhawulweni yokulawula.

2) Ukudla okune-asidi ephansi (isb., isinkwa, amakhekhe): 3% kwatholakala ukuthi une-mycotoxins.

Izinkinga Ezijwayelekile:Okunye ukudla okungenisiwe osekuzophelelwa yisikhathi kubonise ukukhula ngokweqile kwe-microbiological ngenxa yokuhunyushwa kwamalebula okungaphelele, okuholela ezimeni zokulondoloza ezingafanele.

3. I-Scientific Logic Behind Shelf-Life Determination

Impilo yeshelufu yokudla ayiwona umkhawulo olula "wengozi ephephile" kodwa isibikezelo esilondolozayo esisuselwe ekuhloleni ukuphila kweshelufu okusheshisiwe (ASLT). Izibonelo zifaka:

Imikhiqizo yobisi:Ku-4°C, impilo yeshelufu ngokuvamile isethwe ku-60% wesikhathi esidingekayo ukuze isamba sezibalo zamagciwane sifinyelele imikhawulo yokulawula.

I-Puffed Snacks:Uma umsebenzi wamanzi ingu-<0.6, ubungozi be-microbiological buncane, futhi impilo yeshalofu inqunywa ngokuyinhloko ukukhathazeka nge-lipid oxidation.
Lokhu kuphakamisa ukuthi ukudla osekuzophelelwa yisikhathi okugcinwe ngaphansi kwezimo ezihambisanayo kuhlala kuphephile ngokombono, nakuba ubungozi obuncane bukhula kancane kancane.

4. Izinselelo Zemboni kanye Namasu Okuthuthukisa

Izinselelo Ezikhona

1)Amagebe Ekugadweni Kokuhlinzeka Ngempahla:Cishe u-35% wabathengisi abanazo izinhlelo ezizinikezele zokulawula izinga lokushisa zokudla okuseduze nokuphelelwa yisikhathi.

2)Ubuchwepheshe Bokuhlola Obuphelelwe Isikhathi:Izindlela zesiko lendabuko zidinga amahora angama-48 ngemiphumela, okuyenza ingafaneleki emijikelezweni yokusabalalisa ngokushesha.

3)Ukucolisiswa Okujwayelekile Okungenele:Izindinganiso kazwelonke zamanje azinayo imikhawulo ehlukanisiwe ye-microbiological yokudla okuseduze nokuphelelwa yisikhathi.

Izincomo Zokuthuthukisa

1)Sungula amasistimu okuqapha anamandla:

1. Thuthukisa ubuchwepheshe bokutholwa kwe-ATP bioluminescence ukuze kuhlolwe ngokushesha esizeni (imiphumela yemizuzu engama-30).
2. Sebenzisa ubuchwepheshe be-blockchain ukuze ulandele idatha yendawo yokugcina.

2)Thuthukisa Ukumisa:

1. Yethula izimfuneko zokuhlola ezengeziwe zezigaba ezinobungozi obukhulu phakathi nezigaba eziseduze nokuphelelwa yisikhathi.
2. Yamukela indlela yokuphatha enezigaba ebhekisela ku-EU Regulation (EC) No 2073/2005, ngokusekelwe ezimeni zesitoreji.

3)Qinisa Imfundo Yabathengi:

1. Bonisa imibiko yokuhlola yesikhathi sangempela ngamakhodi e-QR emaphaketheni.
2. Fundisa abathengi "ngokuyeka ngokushesha lapho kukhona okungavamile kwezinzwa."

5. Iziphetho kanye ne-Outlook

Idatha yamanje ikhombisa ukuthi ukudla okulawulwa kahle okusondele kokuphelelwa yisikhathi kugcina amazinga aphezulu okuhambisana ne-microbiological, nokho izingozi ezinkambisweni ze-supply chain zidinga ukuqapha. Kunconywa ukwakha uhlaka oluhlanganyelwe lokulawula ubungozi olubandakanya abakhiqizi, abasabalalisi, nabalawuli, ngokuhambisana nokuthuthukiswa kobuchwepheshe bokuhlola obusheshayo kanye nokucwengwa okujwayelekile. Uma ubheka phambili, ukwamukelwa kokupakishwa okuhlakaniphile (isb, izinkomba zezinga lokushisa lesikhathi) kuzonika amandla ukulawulwa kwekhwalithi okunembe kakhudlwana nangokusebenza kahle kokudla osekuzophelelwa yisikhathi.
