Ngokuthuthuka kwamazinga okuphila, abathengi bakhokha ukunakwa okwandayo kwekhwalithi nokuphepha kwenyama. Njengemikhiqizo emibili yenyama evamile, inyama ebabazekayo nenyama eqandisiwe imvamisa kuvame ukuba yimpikiswano mayelana ne- "Fambilo" yazo kanye "nokuphepha". Inyama ebolile iphephe ngempela inyama eqandisiwe? Ingabe inyama eqandisiwe igcwele amagciwane amaningi ngenxa yesitoreji sesikhathi eside? Le ndatshana icubungula ngokugcwele umehluko wokuphepha phakathi kwalokhu okubili ngemininingwane yokuhlola yesayensi, ukutolika kochwepheshe, nokuhlaziywa kwesimo sokusetshenziswa, ukuhlinzeka abathengi ngesisekelo esinengqondo sokwenza izinqumo.
- Inyama efile vs vs. Inyama eqandisiwe: Ukuqhathaniswa kwezincazelo nezinqubo zokucubungula
1)Inyama ebolile: Ukusha okugcinwe emazingeni okushisa aphansi kuyo yonke inqubo
Inyama ebolile, eyaziwa nangokuthi inyama egcinwe ebandayo ebisenze ukususwa kwe-lactic acid, ilandela lezi zinyathelo zokucubungula:
- Ukupholisa okusheshayo ngemuva kokuhlatshwa: Ngemuva kokuhlatshwa, isidumbu sipholile ngokushesha ku-0-4 ° C kungakapheli amahora amabili ukuvimbela ukukhiqizwa kabusha kwe-microbial.
- Ukususwa kwe-lactic acid: Kusele ukuthi kuphumule endaweni yokushisa engaguquki amahora angama-24-48 ukubola i-lactic acid, ukuthambisa imicu yemisipha kanye nokuthuthukisa ukunambitheka.
- Ukuhamba kwama-Cold Chain kulo lonke: Ukusuka ekusetshenzisweni kuyathengiswa, izinga lokushisa ligcinwa ngaphakathi kobubanzi be-0-4 ° C, ngempilo evamile yeshede yezinsuku ezi-3-7.
2)Inyama eqandisiwe: izingidi ezisheshayo ezisheshayo ku "zombuso woqobo"
Umnyombo wokusebenza kwenyama eqandisiwe ulele ku- "Rapid FreeZing Technology":
- I-Super FreeZing: Inyama entsha ngemuva kokubulawa iqashelwa ngokushesha endaweni engezansi -28 ° C, ibangela amanzi we-intracellular ukwakha amakristalu amancane, ukunciphisa ukulimala kwekhwalithi yenyama.
- Isitoreji Eside: Ingagcinwa kwi-Free Cardreet Freezer ku -18 ° C yezinyanga eziyi-6 ukuya kwezi-12 futhi kufanele idliwe ngokushesha ngemuva kokuncipha.
Umehluko Osemqoka:Inyama ebolile igcizelela "ukunambitheka okusha nethenda" kepha kunewindows elifushane lokugcina. Inyama efriziwe imihlatshelo yokunambitha okuthile kwempilo eshelufu eshelelayo.
- Ukuhlolwa kwe-Bacterial Bacterial BacterialIsivivinyo: Inselelo embaxambili yesikhathi nokushisa
Ukuze uqhathanise ukuphepha kwe-microbial zezinhlobo ezimbili zenyama, isikhungo sokuhlola esigunyazayo senze ukuhlolwa okuqoqwe ngengulube kusuka ku-batch efanayo, kulingisa izimo zokugcina zasekhaya:
Idizayini yokuhlola
- Ukuqoqwa kwesampula: I-Fresh Tenderloin ihlukaniswe ngeqembu lenyama elibandayo (esiqandisiwe ku-0-4 ° C) neqembu lenyama eqandisiwe (lifriwe ku -18 ° C).
- Amaphuzu wesikhathi sokuhlola: Usuku 1 (Isifundazwe sokuqala), usuku 3, usuku 7, nosuku lwe-14 (kuphela iqembu leqhwa).
- Izinkomba Zokuhlola: Inani eliphelele lamagciwane (cfu / g), amagciwane e-coliform, namagciwane e-pathogenic (Salmonellana-Staphylococcus aureus).
Imiphumela yokuhlola
| Isikhathi sokuhlola | Inani lamagciwane e-bacterial yenyama ebolile (CFU / G) | Ingqikithi ye-Bacterial Count yenyama eqandisiwe (CFU / G) |
| Usuku 1 | 3.2 × 10⁴ | 1.1 × 10⁴ |
| Usuku 3 | 8.5 × 10⁵ | 1.3 × 10⁴ (okungatholakali) |
| Usuku 7 | 2.3 × 10⁷ (edlula umkhawulo ojwayelekile kazwelonke) | 1.5 × 10⁴ (okungatholakali) |
| Usuku 14 | - | 2.8 × 10⁴ (okungatholakali) |
Ukuhlolwa kwenyama eqandisiwe ngemuva kokuncipha:
Ngemuva kokuncipha nokufakwa emvelweni eyi-4 ° C yamahora angama-24, inani eliphelele le-bacterial likhuphuke libe ngu-4.8 × 10⁵ CFU / G, lisondela ezingeni lenyama ebolile ngosuku 3.
Isiphetho Sokuhlola
1) Inyama ebolile: Inani eliphelele lamagciwane likhuphuka ngokuningiliziwe ngokuhamba kwesikhathi, lidlula umkhawulo we-1 × 10⁷ CFU / g elishiwo "kuzwelonke lokuphepha" eChina "(GB 2707-2016) ngosuku 7.
2) Inyama eqandisiwe
3) Ingozi yamagciwane e-pathogenic: Awekho amagciwane e-pathogenic afana ne-salmonella etholakele kunoma yiliphi iqembu lamasampula. Kodwa-ke, ukubalwa kwamagciwane ngokweqile kwamagciwane kungaholela ekuwohlokeni nase-off-ofmors, okwandisa ubungozi bokusebenzisa.
- Ukusetshenziswa kwemibono eyiphutha nomhlahlandlela wokuthenga wesayensi
I-Misconcy 1: Ingabe inyama ende ephephe ngokuphephile kunenyama eqandisiwe?
Iqiniso: Ukuphepha kokubili kuya ngezimo zokugcina. Uma inyama ebolile ivezwa emashalofini amamakethe isikhathi eside kakhulu noma igcinwe ekhaya isikhathi esingaphezu kwezinsuku ezintathu, ubungozi bungaba buphakeme kunalenyama eqandisiwe.
Umumo ongu-2: Ngabe inyama eqandisiwe ihlupheka ngokulahleka kwezakhi zomsoco?
Iqiniso: Ubuchwepheshe besimanje be-Quick-FreeZing bungagcina ama-90% omsoco, kuyilapho inyama ebolile ithambekele ekulahlekelweni amavithamini anjenge-B1 ngenxa yokusabela kwe-oxidation kanye nokuphendula nge-enzymatic hydrolys.
Ukuthengwa Kwesayensi Nokulondolozwa Kwezinhlelo
1) Inyama ebolile:
Lapho uthenga, qaphela umbala (obomvu okhanyayo nge-gloss), ukuthungwa (okumanzi kancane futhi akunakunamathela), nephunga elimuncu noma le-rancid).
Ukuze uthole ukugcinwa kwasekhaya, bopha inyama ngosongo lweplastiki bese uyibeka engxenyeni ebandayo yesiqandisi (imvamisa eduze nodonga lwangemuva), iwuqede kungakapheli izinsuku ezintathu.
2)Inyama eqandisiwe:
Khetha imikhiqizo enamakristalu amancane e-Ice kanye nokuphaphala okulimazayo, ukugwema "inyama ye-zombie" ebekwe phansi ne-refrozen.
Lapho thawish, sebenzisa "indlela yokushisa yokushisa ye-GRUET": Dlulisela kusuka efrijini esiqandisini amahora ayi-12, bese ufaka emanzini anosawoti ukuze inzalo.
3)Izimiso Ezijwayelekile:
Hlambulula ingaphezulu lenyama ngamanzi agobhozayo ngaphambi kokupheka, kepha gwema ukufaka izinkathi ezengeziwe.
Qinisekisa ukuthi izinga lokushisa lokupheka langaphakathi lifinyelela ngaphezulu kwama-75 ° C ukuhlanganisa kahle ama-bacteria.
