Ithemba Lokufaka Isicelo Se-Cold Sterilization and Preservation Technology of Food liyathembisa

Eminyakeni yamuva nje, imikhiqizo yokupakisha esanda kufakwa yemifino efana nenyama entsha, izithelo ezisikiwe nemifino kanye nokudla okulungiselelwe ikhula ngokushesha ezweni lakithi. Kodwa inkinga yomjikelezo omfushane wokugcinwa okusha kweshalofu lomkhiqizo kanye nokungcoliswa kwesibili sekuphenduke umgoqo wobuchwepheshe obuvimbela ukuthuthukiswa kwezimboni. Ngakho-ke, ucwaningo nokuthuthukiswa kwemikhiqizo yezolimo emisha kanye nobuchwepheshe bokupakisha obusha bokugcina inzalo ebandayo obulungiselelwe ukudla sebuyinto egxile kakhulu embonini.

Ubuchwepheshe bokupakisha bokugcina inzalo ebandayo bungenye yezinkomba zokuthuthukiswa kwesayensi yokudla nobuchwepheshe bamazwe ngamazwe. Inkambu kagesi kagesi ephezulu izinga lokushisa eliphansi lokushisa I-Plasma Cold Sterilization (CPCS) iwukudla okusha ubuchwepheshe bokuvala inzalo ebandayo okwamanje obusetshenziswa emhlabeni wonke. Ikakhulukazi isebenzisa i-plasma yokushisa ephansi efana nama-photoelectrons, ama-ion kanye namaqembu amahhala akhiqizwa abezindaba azungeze ukudla ukuze axhumane nobuso bama-microorganisms. Ukubangela ukubhujiswa kwamangqamuzana ayo ukuze kufinyelele umphumela we-bactericidal. Uma kuqhathaniswa nobuchwepheshe obusetshenziswa kabanzi bokuvala inzalo eshisayo, inkambu kagesi kagesi ephezulu kanye nezinga lokushisa eliphansi lokuvala inzalo ye-plasma kanye nobuchwepheshe bokupakisha bokulondolozwa kuyimpumelelo ebalulekile emkhakheni wokwenza inzalo ebandayo okudla kanye nokucwaninga nokuthuthukiswa kobuchwepheshe bokupakisha. Lobu buchwepheshe bungahlanganiswa nobuchwepheshe be-MAP ukuze kufakwe amagciwane imikhiqizo epakishiwe nge-plasma yezinga lokushisa eliphansi, engeke ikhiqize ukungcoliswa kwesibili. I-plasma ekhiqiza isenzo se-bactericidal ivela kugesi ngaphakathi kwephakheji, ayikhiqizi izinsalela zamakhemikhali, ukuphepha okuphezulu; I-voltage iphezulu, kodwa yamanje incane, isikhathi sokuvala inzalo sifushane, ukushisa akwenziwa, futhi ukusetshenziswa kwamandla kuphansi, ukusebenza kulula, ngakho-ke, ubuchwepheshe bokushisa obuphansi be-plasma yokuvala inzalo bufanele ukuvala inzalo kokudla okuphekiwe okubucayi okubucayi.

Ngaphansi kokusekelwa "kocwaningo nokuthuthukiswa kanye nokuboniswa kwemishini yobuchwepheshe ebalulekile ye-low-temperature-sterilization ye-plasma ye-high-temperature field kagesi," izikhungo zocwaningo lwasekhaya ngokuhlanganyela zakha imishini ephelele ye-plasma epholile-sterilization core imishini yobuchwepheshe, i-MAP yokugcina iphakheji-i-low-temperature ye-plasma yokushisa okuphansi kwe-plasma ekukhiqizeni ukudla okuzenzakalelayo kanye ne-auto-sterikhi yokudla. ukuvala inzalo ebandayo ezweni lakithi. Ngomhla zingama-28 kuNovemba, 2021, i-China Animal Products Processing Research Association yahlela ochwepheshe ukuthi bahlole izimpumelelo zesayensi nezobuchwepheshe zephrojekthi "Ubuchwepheshe obubalulekile kanye nemishini yokuvala inzalo ebandayo ye-plasma kanye nokulondolozwa kanye nokuvala inzalo kwechungechunge olubandayo". Ochwepheshe emhlanganweni bavumelene ngokuthi imiphumela iyonke ifinyelele ezingeni elithuthukile lamazwe ngamazwe, okuhlanganisa inkambu kagesi enengcindezi ephakeme izinga lokushisa eliphansi le-plasma ebandayo inzalo core imishini isifinyelele ezingeni elihamba phambili lamazwe ngamazwe, amathemba abanzi okuthuthukiswa kwezicelo, kuzosiza ekuxazululeni ukudla okulungiselelwe okusha kwamazwe ngamazwe, imboni yekhishi eliphakathi ukuvala inzalo ebandayo ukugcinwa okusha kanye neketango elibandayo lezinto ezihlobene nokhiye bemishini yobuchwepheshe, indawo yemakethe.

Amaphuzu ayinhloko wezobuchwepheshe wephrojekthi ahlanganisa: ukushisa okuphansi kwe-plasma inzalo ebandayo - isikhathi esifushane sokuvala inzalo, ukusetshenziswa kwamandla okuphansi, okulungele ukuthuthukiswa okukhulu kokuvala inzalo okubandayo kokudla okusha nokulungiselelwe; Ubuchwepheshe obuyisisekelo kanye nemishini yokushisa okuphansi kwe-plasma inzalo ebandayo kanye nomugqa wokukhiqiza othomathikhi kungaqeda amagciwane atholakala ekudleni, futhi ukucekelwa phansi kwezinsalela zezibulala-zinambuzane ebusweni bezithelo nemifino kungafinyelela ngaphezu kwama-60%, kunwebe ngempumelelo impilo yeshalofu nokuphila okusha; I-Food cold chain logistics kanye nemishini ekhethekile yobuchwepheshe bokubulala amagciwane komoya wokuphakela izilwane - imishini ekhethekile yobuchwepheshe bokubulala amagciwane emoyeni wokuphakela izilwane ingase ifaniswe nohlelo lwesimanje lwesimo somoya epulazini ukuze kuxazululwe ngempumelelo izinsalela zamakhemikhali nezinye izinkinga.

Ngokuphathelene nomphumela wokufaka isicelo, i-CPCS ekuhlolweni okubandayo kokubulala inzalo kwe-ulethisi yandise kakhulu izinga le-bactericidal, isikhathi esinwetshiwe sokuvuselela ishalofu, futhi ingalulaza ngokuphumelelayo izinsalela zezibulala-zinambuzane ze-organophosphorus ku-ulethisi, ama-strawberry, i-cherry, i-kiwi nezinye izithelo nazo zinomphumela omuhle wokulondoloza inzalo ebandayo kanye nokusebenza kahle kwezinsalela ze-pesticide. Ngasikhathi sinye, ukuhlolwa kokuvala inzalo okubandayo kanye nokugcinwa kokudla okusha, amakhukhamba e-Sichuan, ikhekhe lerayisi le-Ningbo, njll., kuzuze imiphumela yokuqala.
