I-Autoclave: Ukuvimbela ubuthi be-botulism

Ukuvala inzalo ekushiseni okuphezulu kuvumela ukudla ukuthi kugcinwe endaweni efudumele izinyanga noma ngisho neminyaka ngaphandle kokusebenzisa izivimbelakuvunda zamakhemikhali. Kodwa-ke, uma ukuvala inzalo kungenziwanga ngokuhambisana nezinqubo ezijwayelekile zokuhlanzeka nangaphansi kwenqubo efanelekile yokuvala inzalo, kungase kubangele izinkinga zokuphepha kokudla.

Amanye ama-microbial spores angakwazi ukumelana namazinga okushisa aphezulu futhi akhiqize ubuthi obuyingozi empilweni yomuntu. Kunjalo nge-botulism, isifo esibi esibangelwa ubuthi be-botulinum obukhiqizwa i-bacterium Clostridium botulinum.

Ubuthi be-botulism ngokuvamile buba nemiphumela emibi kakhulu.2021 Umndeni wathenga isoseji le-vacuum-packed ham, izinyawo zenkukhu, inhlanzi encane, nokunye ukudla okulula esitolo esincane futhi wakuqeda ngesikhathi sokudla kwakusihlwa, futhi ngakusasa umndeni wabane bonke bahlushwa ukuhlanza, isifo sohudo, nokuba buthakathaka kwezitho zomzimba, okuholela emiphumeleni emibi yokushona komuntu oyedwa kanye nabantu abathathu abagadiwe egunjini labagula kakhulu. Pho kungani kusekhona ubuthi bobuthi be-botulinum obutholakala ekudleni ekudleni okupakishwe ngevacuum?

I-Clostridium botulinum igciwane le-anaerobic, elivame ukutholakala kakhulu emikhiqizweni yenyama, ukudla okusemathinini kanye nokudla okufakwe ivacuum. Imvamisa abantu bazosebenzisa indlela yokushisa ephezulu yokuvala inzalo ukuvala inzalo ekudleni, umkhiqizo osekugcineni inzalo, ukuze kuqinisekiswe ukuthi ukuvala inzalo kuphelele kufanele kufakwe inzalo ekuphenduleni isikhathi eside esanele ukuze kubulawe amagciwane ayingozi kanye nezinhlamvu zawo ekudleni. .

Ukuze ugweme i-botulism, kunezinto ezimbalwa okufanele uzinakekele kakhulu:

1.Sebenzisa izinto zokusetshenziswa ezintsha ezihlangabezana nezindinganiso zokuhlanzeka zokulungiselela.

2.Hlanza kahle zonke izitsha nezitsha ezisetshenzisiwe.

3.Qinisekisa ukuthi ukupakishwa komkhiqizo kuvalwe ngokuqinile.

4.Landela amazinga okushisa nobude bokuvala inzalo okunengqondo.

5.Imingcele yokwelapha inzalo incike ohlotsheni lokudla okufanele kulondolozwe.

Ngokudla okune-acidic (pH ngaphansi kuka-4.5), njengezithelo, ngokwemvelo amelana ne-botulism. Ukuvala inzalo ngamanzi abilayo (100°C) isikhathi okujwayelane nefomethi yokupakisha futhi umkhiqizo othintekayo wanele.

Ngokudla okune-asidi ephansi (i-pH engaphezu kuka-4.5), njengenyama, inhlanzi, nemifino ephekiwe, kufanele kufakwe inzalo ekushiseni okuphezulu ukuze kubulawe izinhlamvu ze-Clostridium botulinum. Ukuvala inzalo ngaphansi kwengcindezi ngezinga lokushisa elingaphezu kuka-100°C kuyanconywa. Inqubo edingekayo izoncika emkhiqizweni nasekufomeni kwawo, amazinga okushisa aphakathi nendawo angaba ngu-120°C.

I-Clostridium botulinum: inzalo nge-autoclave yezimboni

I-Industrial autoclave inzalo iyindlela ephumelela kakhulu yokuvala inzalo yokubulala i-Clostridium botulinum, igciwane elidala i-botulism. Ama-autoclave ezimboni angafinyelela amazinga okushisa aphezulu kakhulu kunama-autoclave asekhaya, aqinisekise ukubhujiswa kwamagciwane.

I-DTS autoclave retort iqinisekisa ukusabalalisa okuhle kwezinga lokushisa kanye nokuphindaphinda komjikelezo emkhunjini, okuyisiqinisekiso sokuphepha sokuvalwa inzalo okuphephile.

I-DTS iyaphendula: Ukuvala inzalo ngokuzethemba

I-DTS inikezela ngezinhlobonhlobo zama-autoclave embonini yokudla. Idizayini yalokhu kubuyiselwa iqinisekisa ukufana okuhle kakhulu kokusatshalaliswa kokushisa phakathi nenqubo yokuvala inzalo yokudla, okuqinisekisa umphumela wokuvala inzalo olinganayo kuyo yonke imikhiqizo elayishiwe. Isistimu yokulawula ye-autoclave iqinisekisa ukuphepha kwenqubo yokudla futhi iqinisekisa ukuphinda umjikelezo ophelele.

Ngaphezu kwalokho, ithimba lethu lochwepheshe lizokunikeza ukwesekwa kwezobuchwepheshe ekusetshenzisweni kwama-autoclave ukuze uvale inzalo ephephile futhi enokwethenjelwa.
