Uma uthatha iphakethe lamabhisikidi, ibhodlela likajamu, noma iphakethe lamasoseji esitolo, cishe uzobona okuthile okubizwa ngokuthi 'izilondolozi' phakathi kwezithako. Ngezinye izikhathi lokhu kufakwa ohlwini njengenombolo E. Ziyini ngempela lezi zilondolozi? Kungani zengezwa ekudleni? Azilungele yini imizimba yethu? Namuhla, ake sixoxe nje ngale mibuzo abantu abaningi abanayo.
Kungani sidinga ukugcina ukudla?
Kalula nje, izithasiselo ziyizinto ezivimbela ukudla ukuthi kungonakali ngokushesha. Ngaphandle kwazo, ukudla okuningi esikudlayo kungaba nesikhunta, konakale, futhi kube yingozi phakathi nosuku noma ezimbili.
Cabanga ngakho, esikhathini esidlule, ogogo nomkhulu bethu babesebenzisa usawoti ukwenza izithelo ezomisiwe, uviniga wokubhaka, kanye noshukela noju ukuze kulondolozwe ukudla okumnandi (njenge-dodol, i-kevumu) ngenxa yalesi sizathu. Lezi kwakuyizindlela zemvelo zokulondoloza ezazitholakala ngaleso sikhathi. Abakwenzayo ukuvimba ukukhula kwamagciwane awonakalisa ukudla futhi asigulise, okungukuthi amagciwane, imvubelo, kanye nesikhunta.
Kulezi zinsuku, kanye nalezi zindlela zemvelo, izithasiselo zokwenziwa ezenziwe emalabhorethri nazo zisetshenziswa kabanzi embonini yokudla. Lokhu akugcini nje ngokungezwa ekudleni, kodwa nasezimonyweni nakweminye imithi oyisebenzisayo. Zisetshenziselwa ukwandisa isikhathi sazo sokuphelelwa yisikhathi.
Into ebaluleke kakhulu ukuthi zonke izilondolozi ezifakwe ekudleni, kungakhathaliseki ukuthi zendalo noma zokwenziwa, zilawulwa ngokuqinile yiziphathimandla zikahulumeni zokuphepha kokudla futhi zivunyelwe njengezifanele ukudliwa ngabantu.
Ziyini lezi zilondolozi zemvelo?
Izithako zemvelo, njengoba negama lisho, yilezo ezivela emithonjeni yemvelo. Okusho ukuthi, ezintweni ezifana nezitshalo, izilwane, isikhunta, noma ulwelwe. Azidalwanga ngokwenziwa emalabhorethri.
Izinto eziningi esizisebenzisayo ekuphileni kwethu kwansuku zonke ziyizinto zemvelo zokulondoloza imvelo.
- Usawoti: Isithako esiyinhloko esisetshenziselwa ukomisa nokugaya inyama nenhlanzi.
- Ushukela: Ushukela usiza ekulondolozeni izinto ezifana nejamu, i-cordial, ne-toffee.
- Uviniga: I-acetic acid ekuwo ivimbela ukukhula kwamagciwane. Ibalulekile kuma-pickle.
- I-Citric Acid: Itholakala ngokwemvelo ezithelweni ezifana nolamula, amawolintshi, kanye ne-grapefruit. Inezela ukunambitheka okumuncu ekudleni futhi ivimbela nezithelo ezisikiwe (njengama-apula) ukuthi zingabi nsundu.
- I-Rosemary Extract: Lokhu kuyi-antioxidant enamandla. Lokhu kusho ukuthi ivimbela ukudla okunamafutha (amasoseji, inyama) ukuthi kungadli futhi kunambitheke kungadli.
- Ezinye izingcezu zezitshalo namafutha abalulekile: Amafutha atholakala ezinongo ezifana nesinamoni nama-clove nawo anezakhiwo zokulondoloza.
Ngaphezu kwalokhu, kwezobuchwepheshe bokudla, izinto ezifana ne-'Chitosan' (into etholakala emagobolondweni ezilwane ezifana nezinkalankala nama-shrimp) kanye ne-'Bacteriocins' (izinto ezikhiqizwa amabhaktheriya awusizo) nazo zisetshenziswa njengezilondolozi zemvelo.
Uyini umehluko phakathi kwezinto zemvelo nezinto zokwenziwa?
Nakuba inhloso eyinhloko yazo zombili iwukuvimbela ukudla ukuthi kungonakali, kukhona umehluko ocacile phakathi kwazo. Masiqonde ngosizo lwetafula.
| Isici | Izithako zemvelo zokulondoloza | Izithako zokwenziwa |
|---|---|---|
| Umthombo | Izinto zemvelo njengezitshalo, izingxenye zezilwane, amaminerali (usawoti). | Amakhemikhali akhiqizwa ngokwenziwa emalabhorethri. |
| Izibonelo | Usawoti, ushukela, uviniga, ijusi likalamula (i-citric acid), izinongo. | I-Sodium Benzoate, i-Sulphur Dioxide, ama-Nitrate, i-BHA, i-BHT. |
| Imiphumela engaba khona empilweni | Ngokuvamile kuphephile. Kodwa-ke, uma kudliwa ngokweqile (usawoti, ushukela), kungase kube nezinye izinkinga zempilo. Abanye abantu bangase babe nokungezwani komzimba. | Ezinye izifundo zibonise ukuthi abantu abazwelayo bangase babe nezimo ezifana ne-asthma, ukungezwani komzimba, izifo zesikhumba, kanye nokusebenza ngokweqile. |
| Izindleko nokutholakala | Ngokuvamile kuyabiza. Kungaba nzima ukukukhiqiza. Kungase kungasebenzi kahle njalo. | Ayibizi kakhulu. Ingakhiqizwa kalula ngobuningi obukhulu. Ibonisa ukusebenza kahle okukhulu ngisho nangobuningi obuncane kakhulu. |
Ingabe izinto zokwenziwa ziyingozi ngempela?
Abantu abaningi bayesaba uma kukhulunywa ngezilondolozi zokwenziwa. Eqinisweni, ezinye izifundo zithole imiphumela emibi. Isibonelo, amanye ama-nitrate angaba umdlavuza, kanti amanye amadayi nama-benzoate angahlotshaniswa nokusebenza ngokweqile ezinganeni.
Kodwa nansi into ebalulekile okufanele uyiqonde. Lezi zinto zengezwa ekudleni ngamanani amancane kakhulu, aphephile. Izinkampani zokudla kufanele zilandele ngokuqinile le mithetho. Ngakho-ke, amathuba okulimala okukhulu okuvela ezintweni esivame ukuzidla neziziphuzayo mancane kakhulu.
Kodwa-ke, uma uzwa ukusabela kokungezwani komzimba, ukuqubuka kwesikhumba, noma ezinye izimpawu ezingavamile ngemva kokudla ukudla okuthile, ungase ube nokusabela kokungezwani komzimba kokuthile okukulokho kudla. Ezimweni ezinjalo, kungcono ukukhuluma nodokotela wakho ngakho.
Izinzuzo zezilondolozi
Nakuba sikhuluma ngezinye zezinto ezimbi zalokhu, kunezinzuzo eziningi esizitholayo ezigcinini.
1. Ukuphepha Kokudla: Kusivikela ezifweni ezibangelwa ukudla ngokuvimbela amagciwane ayingozi njenge-botulism engakhula enyameni nasezinhlanzini.
2. Ukunciphisa imfucuza yokudla: Njengoba ukudla kungagcinwa isikhathi eside, imfucuza yokudla ngesikhathi sokuthuthwa nokugcinwa kwayo incishiswa kakhulu.
3. Ukudla okungabizi: Ngenxa yokuthi imfucuza yokudla iyancipha futhi ukukhiqizwa kwayo kungenziwa ngobuningi, singakwazi ukuthola ukudla okuhlukahlukene ngamanani afanele unyaka wonke.
4e Ukulondolozwa kokudla okunempilo: Ezinye izilondolozi, ikakhulukazi ama-antioxidants, zivimbela ukubola kanye nokubhujiswa kwamavithamini nezakhamzimba ekudleni.
Umlayezo Wokuya Nawe Ekhaya
- Izithako zokugcina ukudla ziyizithako ezibalulekile eziqinisekisa ukuphepha kwethu ngokuvimbela ukudla ukuthi kungonakali ngokushesha, kukhunte futhi kube yingozi.
- Lezi zihlukaniswe ngezinhlobo ezimbili eziyinhloko: zemvelo (njengosawoti, ushukela, kanye noviniga) kanye nezokwenziwa (ezenziwe emalabhorethri).
- Nakuba izinto zemvelo ngokuvamile zibhekwa njengeziphephile, izinto zokwenziwa nazo zisetshenziswa ngaphakathi kwemingcele yokuphepha, elawulwa ngokuqinile nguhulumeni.
- Uma uthenga okuthile esitolo, kuwumqondo omuhle ukufunda ilebula bese uqaphela ukuthi kukhonani kulo. Ungakhetha nokudla okuthi 'Azikho izithasiselo ezengeziwe'.
- Uma unenkinga, izinsolo, noma ukungezwani nokudla noma isithako esikuyo, qiniseka ukuthi uxoxa ngakho nodokotela wakho.
