NgokweNational Science Foundation (NSF), bangu-78% abathengi ababika ukuthi balahla ubisi neminye imikhiqizo yobisi uma usuku lokulebula seludlulile (1).

Noma kunjalo, usuku obisini lwakho alukhombisi ukuthi akusaphephile ukuphuza. Eqinisweni, ubisi obuningi bungadliwa ezinsukwini ezimbalwa kudlule usuku oluprintwe kulebula.

Lo mbhalo uchaza ukuthi lisho ukuthini usuku lobisi lwakho nokuthi luphephe kangakanani ukuphuza ngemuva kosuku oluprintiwe.

Kusho ukuthini usuku obisini lwakho

Ukudideka kokufakwa kwelebula kosuku kuma-akhawunti wokudla cishe ama-20% kadoti wokudla wabathengi e-United States ().

Lokhu ikakhulukazi kungenxa yokuthi i-Food and Drug Administration (i-FDA) ayilawuli ukufakwa kwelebuli kosuku lwemikhiqizo yokudla, ngaphandle kwefomula yezinsana (, 3).

Ezinye izifundazwe zilawula ukuthi izinsuku zokuphelelwa yisikhathi zobisi kufanele zibhalwe kanjani, kepha le mithetho iyahluka phakathi kwezifundazwe (4).

Lokhu kusho ukuthi ungabona izinhlobo eziningi zamadethi ebhokisini lakho lobisi - akukho nolunye olubonisa ukuphepha kokudla (3):

• Kuhle uma kusetshenziswe ngu. Lolu suku lukhombisa ukuthi uzoludla nini ubisi ngekhwalithi engcono kakhulu.
• Thengisa ngezi. Lolu suku lungasiza ezitolo ngokuphathwa kwempahla, njengoba isitshela ukuthi uluthengisa nini ubisi ngokuqinisekisa ikhwalithi engcono kakhulu.
• Sebenzisa nge. Lolu suku wusuku lokugcina ongalindela ukuthi umkhiqizo ube sezingeni eliphakeme ngalo.

Ngakho-ke, usuku oluphrintiwe lungakunika umbono wokuthi ikhwalithi izoqala nini ukwehla. Kodwa-ke, akusho ukuthi ubisi lwakho luzophelelwa yisikhathi futhi luphephe ukuphuza ngokushesha ngemuva kwalolo suku.

I-FDA ayidingi ukuthi abakhiqizi baphrinte usuku lokuphelelwa yisikhathi obisini. Esikhundleni salokho, uvame ukubona usuku "lokusebenzisa" noma "lokuthengisa ngo", okuyisincomo maqondana nekhwalithi, hhayi ukuphepha.

Kuphephe kangakanani ukuphuza ubisi ngemuva kosuku lokuphelelwa yisikhathi?

E-United States, ubisi oluningi oluthengwa esitolo luye lwagcotshwa (5).

I-Pasteurization inqubo ebandakanya ukufudumeza ubisi ukuqeda amagciwane angaba yingozi, kufaka phakathi E. coli, IListeria, futhi Salmonella. Ngokwenza lokhu, impilo eshalofini yobisi inwetshwa ngamaviki ama-2-3 (, 7).

Kodwa-ke, i-pasteurization ayikwazi ukubulala wonke amabhaktheriya, futhi lawo asele azoqhubeka nokukhula, ekugcineni abangele ubisi lonakalise ().

Olunye ucwaningo luthole ukuthi izinga lokushisa esiqandisini sakho kuthinta kakhulu ukuthi ubisi lwakho luhlala kahle kangakanani esikhathini esedlule kosuku olubaliwe. Ngokunciphisa nje ukushisa kwesiqandisi kusuka ku-43 ° F (6 ° C) kuye ku-39 ° F (4 ° C), impilo yeshalofu yandisiwe ngezinsuku eziyi-9 ().

Ngenkathi kungekho izincomo ezisethiwe, ucwaningo oluningi lukhombisa ukuthi inqobo nje uma lugcinwe kahle, ubisi olungavulwa ngokuvamile luhlala luhle izinsuku ezingama-5-7 kudlule usuku lwalo olubaliwe, ngenkathi ubisi oluvuliwe luhlala okungenani izinsuku ezingama-2-3 ngaphambi kwalolu suku (3, , 9).

Ngaphandle kokuthi ubisi luzinzile eshalofini, akufanele lushiywe ngaphandle ekamelweni lokushisa isikhathi esingaphezu kwamahora amabili, ngoba lokhu kukhulisa ubungozi bokugula okubangelwa ukudla (3).

Ngokuphambene nalokho, ubisi oluhlaza aluzange luthanjiswe futhi lunempilo eshalofini emfushane. Ukuphuza lolu hlobo kungakhuphula nobungozi bokugula okubangelwa ukudla (,).

Ekugcineni, kukhona ubisi olungafakwa esiqandisini, olubizwa nangokuthi ishelu-esitebeleni noma ubisi lwe-aseptic, olukhiqizwa kusetshenziswa i-ultra-heat treatment (UHT). I-UHT iyafana nokunamathisela kodwa isebenzisa ukushisa okuphezulu, okwenza imikhiqizo yobisi engavulwa iphephe ukuyigcina ekamelweni lokushisa ().

Lungavulwa, ubisi lwe-UHT ngokuvamile lungahlala amasonto amabili kuya kwamabili kudlule usuku oluphrintiwe uma ligcinwe endaweni epholile, eyomile, kuze kufike ezinyangeni eziyi-1-2 efrijini. Kodwa-ke, uma seluvuliwe, ubisi lwe-UHT kufanele lugcinwe efrijini bese luqedwa zingakapheli izinsuku eziyi-7-10 (9).

Vele, ngaphandle kosuku olukuhlu, ngaso sonke isikhathi kubalulekile ukuhlola ubisi lwakho kuqala ukuthola noma yiziphi izimpawu zokonakala, okufana nephunga elimuncu noma ushintsho ekubunjweni.

Izindlela zokwenza ubisi lwakho luhlale isikhathi eside

Ubisi lungalunga izinsuku ezimbalwa ngemuva kokuthengiswa noma kosuku oluhle kakhulu. Kodwa-ke, usengagcina ubisi olonakele uma ungalugcini futhi uluphethe kahle.

Nawa amathiphu ambalwa wokuthi ungagcina kanjani ubisi lwakho lungonakali ngokushesha (13):

• ngaphandle kokuthi kuzinzile eshalofini, beka ubisi efrijini ngokushesha okukhulu emva kokuthenga
• gcina izinga lakho lokushisa esiqandisini liphakathi kuka-38 ° F (3 ° C) no-40 ° F (4 ° C)
• gcina ubisi eshalofini elingaphakathi efrijini lakho hhayi eshalofini emnyango
• ngemuva kokusetshenziswa, hlala uvalwe njalo futhi ubuyisele ibhokisi ngokushesha efrijini

Ngenkathi ubisi lungabanda kuze kube izinyanga ezi-3, ukuqandisa nokuncibilikisa okulandelayo kungaholela ekuguqulweni okungathandeki kokuthungwa nombala. Lokho kusho ukuthi kuzobe kuphephile ukuphuza (14).

Ngisho nangemva kokuvulwa, ubisi oluningi luphephile ukuphuzwa izinsuku ezimbalwa ngaphambi kosuku lokusebenzisa noma lokuthengisa. Ukugcinwa nokuphathwa ngendlela efanele kungayisiza ukuthi ihlale isha futhi iphephile isikhathi eside. Kodwa-ke, kubalulekile njalo ukuhlola izimpawu zokonakala ngaphambi kokuphuza.

Ungabona kanjani ukuthi ubisi lusaphephile yini ukuphuzwa?

Njengoba usuku obisini lwakho lungakhombisi ngaso sonke isikhathi ukuphepha, indlela engcono yokutshela ukuthi ubisi lulungile yini ukuphuza ukusebenzisa izinzwa zakho.

Esinye sezimpawu zokuqala ukuthi ubisi lwakho seluphelelwe yisikhathi ukushintsha kwephunga.

Ubisi olonakalisiwe lunephunga elimuncu elihlukile, elibangelwa i-lactic acid ekhiqizwa ngamagciwane. Ezinye izimpawu zokonakala zihlanganisa umbala ophuzi kancane nokuthungwa okuyisigaxa (15).

Izimpawu zokuthi ubisi lwakho lonakele futhi kungenzeka lungaphephile ukuphuza zifaka iphunga elimuncu nokunambitheka, ukushintsha kombala, nokuthungwa okuyisigaxa.

Imiphumela emibi engaba khona yokuphuza ubisi oluphelelwe yisikhathi

Ukuphuza isiphuzo noma ezimbili zobisi olonakele akunakwenzeka ukuthi kubangele imiphumela emibi kakhulu.

Kodwa-ke, ukusebenzisa amanani amaphakathi noma amakhulu kungadala ubuthi bokudla futhi kuholele kwizimpawu ezinjengokucanuzela kwenhliziyo, ukuhlanza, ubuhlungu besisu, nohudo ().

Uma izimpawu ziqhubeka noma ziba zimbi, noma uma uqala ukuhlangabezana nezimpawu zokuphela kwamanzi emzimbeni, kubalulekile ukwenza i-aphoyintimenti nomhlinzeki wakho wezokunakekelwa kwempilo ().

Ngenkathi ukuphuza ubisi olonakele kungenzeki ukuthi kubangele ukulimala, ukuphuza isilinganiso esilinganiselwe kuya kwesikhulu kungadala ubuthi bokudla futhi kuholele kwizimpawu ezinjengokuhlanza, ubuhlungu besisu nohudo.

Okubalulekile

Ngenxa yokudideka ngokufakwa amalebula emabhokisini amasi obisi, abathengi abaningi balahla ubisi ngaphambi kokuba lubi.

Yize kuhlale kubalulekile ukuhlola ubisi lwakho ngaphambi kokuliphuza, ubisi oluningi luphephile ukuphuza ezinsukwini ezimbalwa ngemuva kosuku oluprintiwe kwilebula. Lokho kusho ukuthi, ukunambitheka kungaqala ukwehla.

Ukugwema ukusaphazeka kokudla, ubisi oludala lungasetshenziswa kuma-pancake, izimpahla ezibhakiwe noma isobho.
