Vumela ukuthi ubhekisise imisebenzi esemqoka yamathini okupakisha ukudla: ukuphepha, ukuzivikela, inzuzo, ukusebenza kahle kanye nemininingwane.
1, ukuphepha nokuvikeleka nokuvikelwa
Amathini okufaka ukudla ukusiza ukwandisa isikhathi sokuphila. Lokho kusho ukuthi ukugcina ukudla bekungekho engcupheni yokudla isikhathi eside. Ukuvezwa ngqo kwe-oxygen kungadala ukubola, ngakho-ke okunye ukudla kudinga ukupakishwa komkhiqizo ongangeni emoyeni. Ukuchitha noma ukuthola umswakama nakho kungaba yinkinga. Awufuni ukuthi ukudla kwakho kukugulise, futhi namathini okupakisha ukudla angalondoloza ama-microbes adala isifo esibangelwa ukudla.
Ukupakisha ngokungeziwe kufanele kuvikele ukudla ekushayweni noma ekulimaleni- akekho umuntu ongalokotha athumele amaqanda esikhwameni sephepha.
2, Ukusebenziseka kalula, ukusebenza ngempumelelo, kanye nolwazi
Isayensi yokupakisha ukudla kwethini ibingenza kube lula kuwe ukuthi ubambe okudingayo futhi ube nenani elifanele. Ungakugcina ukudla kwakho, uvule inqwaba, ubone ukuthi yini oyisebenzisayo futhi ususe kahle lapho ingasafanele ukusetshenziswa noma ukusetshenziswa kabusha.
Iziqukathi zethini zokupakisha ukudla nazo zingumthombo wakho oyinhloko wolwazi maqondana nento engaphakathi, njengokubaluleka kokudla okunempilo, izithako ezisebenzayo, kanye nosuku lokuphelelwa isikhathi kakhulu. Ezinye iziqukathi zokudla kukathayela nazo ziletha ukuphepha kokudla namathiphu okuphepha kanye nemiyalelo yokupheka - kwesinye isikhathi ngisho nesidlo seresiphi entsha sha!
Ukupakisha kwethini lokugcina ukudla kusisiza futhi ukulandelela ukudla lapho kunokukhumbula ukudla noma kunenkinga ngomkhiqizo ongahle usigulise. Ngokwe-IFT's International Food Traceability Facility, ukulandelela kuvumela amafemu ukuthi "alandelele imikhiqizo ngokusebenzisa i-supply chain ukuze kuthuthukiswe ukuphepha nokuvikeleka kokudla, kunciphise ubungozi, kugweme ukonakalisa imiphumela yezempilo nenhlalakahle, kanye nokulahleka komnotho ohlelweni lokudla." Ama-barcode amakhodi ahlukile ohlelweni losizo alandelela leyo nto ukusuka kwelinye iphuzu kuye kwelilandelayo, okwenza kube nokwenzeka ukubeka imikhiqizo noma kuphi kanye nohlelo lokudla.
3, Imikhiqizo Esetshenziselwe Ukusetshenziswa kwamathokheni okufaka ukudla
Ukupakisha kweziqukathi zokudla kungenziwa ngeGlasi, insimbi, iphepha noma upulasitiki- ngezikhathi ezithile ku-mix- futhi ezinye izinto zisebenza kangcono ezinhlotsheni ezahlukahlukene zokudla. Ake sihlole okubalulekile:
Ingilazi. Ingilazi ingumkhiqizo wokuqala wokuphakwa kokudla, ubuya iminyaka engaba ngu-5,000. Inzuzo enkulu ukuthi i-chemistry inert, enikeza umgwaqo odongeni owesabekayo ngokumelene nezibuko kanye namagciwane. Kungenziwa sanat futhi kulula ukuphindaphinda futhi usebenzise kabusha. Izici ezingezinhle ukuthi i-Glass is hefty futhi iyaphuka. Noma ngabe kukuphi konke ukudla okuthola emathinini okulondolozwa kokudla namabhodlela, i-Glass ihlanganisa cishe amaphesenti ayishumi okufakwa kokudla.
Amasimbi. Ukufakwa kweziqukathi zensimbi yensimbi enjenge-aluminium engasindi, insimbi efakwayo, nensimbi engenalo ugesi ngenxa yama-1900s. Ama-Steels ngaphezu kwalokho anezindawo ezinkulu zokuvimbela indawo yokuhlala. Zingalashwa ngokushisa futhi ziboshwe ngenxa yokuqina. I-aluminium engasindi eyenziwe ngqo ku-foil ingenziwa ngqo kumakhandlela akhanyayo, abushelelezi weziphuzo ezithambile. I-Tinplate iphephile futhi ingenziwa isetshenziselwa iziphuzo zekhukhamba, ukudla okucolisisiwe, kanye namathini ka-aerosol (njengo-ukhilimu ophehliwe) Insimbi engenayo i-tin ayinamandla kakhulu futhi futhi ingasetshenziselwa izithako zemigqomo nezigubhu ezinkulu zezinto ezithengiswa ngobuningi.
Iphepha kanye nephepha. Lolu hlobo lokupakisha lubuyela emuva kuma-1600s. Izithintelo zokuhlala zephepha zingavunyelwe, ngakho-ke ukuze zisetshenziswe njengesitsha sokudla, kufanele ziphathwe nge-wax, i-lacquer, noma impahla. Ezinye izimo ziqukethe iphepha lokuklanywa kanye nelesiikhumba, okudingwa ngalo ukulenza lithambeke kakhulu emanzini kanye no-oyela.
Iphakethe lokufaka iphepha lokudla lisetshenziselwa ukuhambisa amabhokisi okudla. Uma ufaka womabili amaphepha kanye nephepha, zibalelwa kumaphesenti angama-35 okufakwa kokudla.
Emakotini ahamba phambili ngokufakwa kokudla. Ukudla kuyalondolozwa, impilo ende (ukufakelwa i-airtight), futhi futhi okusha. Ukubaluleka kokudla okunempilo kuyaqhubeka nokuba njalo. Izitini zezitini zilula futhi ukuzidlulisa, noma phakathi kobubanzi obude.
I-tin yethu ingathwala umkhiqizo ifinyelela izidingo zokuphepha kokuphepha nokuphepha futhi ilungele kakhulu ukugcwaliswa kwe-Broadband.
