Izindawo zokugcina izidumbu ezibandayo zidlala indima ebalulekile embonini yokucubungula inyama yanamuhla. Zenza okungaphezu nje kokuqandisa inyama ukuze igcinwe. Ezimweni eziningi, lezi zindawo kumele futhi zisekele ukubanda ngemva kokuhlatshwa, ukulawulwa kokwehla kwe-pH, kanye nokuguga kwenyama yengulube, inyama yenkomo, kanye newundlu. Lezi zidingo ezisebenzayo zenza indawo yokugcina izidumbu ebandayo ihluke kakhulu emakamelweni abandayo avamile asetshenziselwa ukugcina ukudla okuvamile.
Izigaba Eziyinhloko Zendawo Yokugcina Izinto Ezibandayo Zokubulala
Izindawo zokugcina izinto ezibandayo zasezilaheni ngokuvamile ziwela ezigabeni ezimbili eziyinhloko: amakamelo okubanda abandayo nawokuguga kanye namagumbi okubanda abandayo. Lokhu kuhlukaniswa kulandela amazinga amukelekile emhlabeni wonke okulawula izinga lokushisa eliyinhloko lenyama kulo lonke ukucubungula nokugcina.
Amakamelo abandayo abandayo futhi agugayo agxila ekunciphiseni ngokushesha izinga lokushisa eliphakathi kwezidumbu ezisanda kuhlatshwa. Kungakapheli amahora angama-24 ngemva kokuhlatshwa, abaqhubi behlisa izinga lokushisa eliphakathi libe sezingeni eliphephile. Le nqubo icindezela ukukhula kwamagciwane ayingozi njengeSalmonella ne-Escherichia coli. Ukuphola okuphumelelayo kubuye kuzinzise isakhiwo semisipha futhi kulungiselele inyama ukuthi icutshungulwe kabanzi.
Amakamelo abandayo aqandisayo anenhloso ehlukile. Ngemva kokubanda nokuguga, abaprosesa banciphisa izinga lokushisa lenyama elingaphakathi libe yi-−18°C noma ngaphansi. Leli zinga lokushisa livumela ukugcina isikhathi eside kanye nokuthuthwa ibanga elide ngenkathi kugcinwa amazinga ekhwalithi nokuphepha amukelekayo.
Izindawo zokuxhela ezincane zivame ukusebenza ngezindawo eziyisisekelo kuphela. Ngokuvamile zifaka amakamelo okubanda abandayo nawokuguga kanye nendawo yokugcina impahla yesikhashana efrijini. Lezi zitshalo zigxila ekusatshalalisweni kwendawo kanye nokushintshashintsha okusheshayo. Izindawo zokuxhela ezinkulu zivame ukufaka uhla oluphelele lwezinhlobo zokugcina izinto ezibandayo. Ziphinde zengeze amakamelo okupholisa okusika nokususa amathambo ukusekela ukucutshungulwa kokuthunyelwa kwamanye amazwe kanye nokuhambisana nezindinganiso zomhlaba wonke.
Ezinye izindawo zokulahlela zihlose izimakethe zabathengi abaphambili. Lezi zindawo zitshala imali emakamelweni abandayo azinikele okuguga kanye namakamelo abandayo aqandisa ngokushesha. Ngokwandisa isikhathi sokuguga sibe yizinsuku ezingu-7-28, abakhiqizi bathuthukisa ubumnene, ubunzima bokunambitheka, kanye nekhwalithi yokudla iyonke. Amakamelo abandayo aqandisa ngokushesha anciphisa ngokushesha izinga lokushisa elingaphakathi, okunciphisa ukwakheka okukhulu kwekristalu yeqhwa futhi kuvikele imicu yemisipha. Le ndlela igcina ukuthungwa kokuqala kwenyama kanye nokunambitheka kwayo ngezinga elikhulu.
Indima Nokubaluleka Kokuphola Nokuguga
Ukushisa nokuguga kumelela izinyathelo ezibalulekile ekuhlatshweni kwemfuyo emikhulu. Ukuguga okufanele kuthuthukisa ukunambitheka, ukuthungwa, kanye nokuvumelana. Kuphinde kunciphise ukuguquguquka phakathi kwezidumbu, okuzuzisa kokubili abacubungulayo kanye namakhasimende okugcina.
Ngemva kokuhlatshwa, ukuphumula kwenyama kuvumela i-lactic acid ngaphakathi kwezicubu zemisipha ukuthi iqhekeke kancane kancane. Imicu yemisipha iyakhululeka njengoba i-rigor mortis iphela. Phakathi nalesi sikhathi, amaprotheni athile alawulwa yi-hydrolysis. Le nqubo yamakhemikhali ithambisa isakhiwo senyama futhi ithuthukise ukuhlafunwa.
Njengoba i-lactic acid incipha, i-pH yemisipha iya ezingeni elingathathi hlangothi. Lokhu kushintsha kuzinzisa izakhiwo zamaseli ngaphakathi kwenyama. Amaseli azinzile agcina amanzi kahle ngesikhathi sokupheka. Ngenxa yalokho, inyama egugile inikeza ujusi ophezulu, umuzwa womlomo othuthukisiwe, kanye nokugcinwa okungcono kwezakhamzimba.
Ukuguga kusiza futhi ukunciphisa iphunga elingathandeki. Amanye ama-amino acid aqukethe i-sulfur ayabola kancane kancane ngesikhathi sokuguga. Lokhu kusabela kunciphisa iphunga elinamandla elibonakalayo elitholakala enyameni yenkomo, imvu, kanye nengulube. Abathengi bavame ukuhlobanisa lokhu kuthuthukiswa nokusha kanye nekhwalithi ephezulu.
Izimiso Zokuklama Zamakamelo Abandayo Abandayo Nokuguga
Abaklami kumele balungise imingcele yokubanda nokuguga ngokusekelwe kuhlobo lwenyama kanye nemigomo yokucubungula. Kodwa-ke, ulwazi lwemboni lubonisa ukuthi u-0–4°C unikeza izinga lokushisa elifanele kakhulu lokuguga inyama ebomvu eminingi. Ukulawula izinga lokushisa okuzinzile kubaluleke kakhulu kunokushisa okukhulu. Ukuguquguquka kungaphazamisa ukusabela kwamakhemikhali futhi kunciphise ukusebenza kahle kokuguga.
Ukulawulwa komswakama kudlala indima ebaluleke ngokulinganayo. Ukuze kuvinjelwe ukuphelelwa amanzi emzimbeni kanye nokulahlekelwa yikhwalithi, abaklami bavame ukugcina umswakama ophakathi kuka-85% no-95%. Umoya owomile kakhulu ubangela ukuqhekeka kobuso, okuphazamisa ukuguga futhi kunciphisa isivuno. Kodwa-ke, umswakama owedlulele wandisa ingozi yokukhula kwesikhunta.
Izinhlelo zokungenisa umoya zidinga ukuhlela ngokucophelela. Ukuhamba komoya okufanele kuvimbela izindawo zomoya ezimile futhi kunciphise ukukhula kwamagciwane. Ngesikhathi esifanayo, abaklami kumele bagweme ukuvunguza komoya obandayo ngqo ezindaweni zenyama. Onjiniyela bavame ukushintsha izikhundla ze-evaporator noma basebenzise ama-air deflector. Le ndlela igcina izinga lokushisa elifanayo ngaphandle kokoma ngokweqile.
Izinto Okucatshangelwayo Ngokuhlelwa Kokusebenza Nokusebenza Kahle
Inyama ngokuvamile idinga usuku olulodwa kuya kwezimbili ukuze iqedele ukubanda nokuguga okujwayelekile. Izinhlelo zokuguga ezinde zidinga isikhathi eside kakhulu sokugcina. Lezi zidingo zesikhathi zithonya kakhulu ukwakheka kwegumbi lokubanda kanye nokuhlela umthamo.
Ukuze kugcinwe ukusebenza kahle komkhiqizo, izindawo zokulahlela zivame ukwakha izindawo eziningi zokuphola nezokuguga. Ezinye izindawo zihlukanisa amakamelo amakhulu abe yizingxenye eziningana ezizimele. Lokhu kulungiselelwa kuvumela abaqhubi ukuphatha amaqoqo ahlukene ngesikhathi esisodwa. Kuphinde kunciphise izingozi zokungcoliswa okuhlukahlukene futhi kuthuthukise ukuguquguquka kokuhlela.
Ukuhlukaniswa kwezindawo okusebenzayo kusiza izindawo zokulahlela ukubulala ukhula zilinganise izidingo zezinto eziphilayo kanye nengcindezi yezentengiselwano. Ngokuvumelanisa ukwakheka kwendawo yokugcina ebanda nomthamo wokulahlela kanye nokugeleza komkhiqizo, abaqhubi bathuthukisa umkhiqizo ngenkathi begcina amazinga ekhwalithi kanye nokuphepha.
Izinhlelo zokugcina izinto ezibandayo zasezilaheni zakha igatsha elikhethekile kakhulu lobunjiniyela be-cold-chain. Zihlanganisa ukuphepha kokudla, isayensi yenyama, kanye nokusebenza kahle kwezimboni zibe yingqalasizinda eyodwa. Ukupholisa, ukuguga, kanye nokuqandisa kufeza izinjongo ezihlukile kodwa ezixhumene. Ukusetshenziswa kwazo okuphumelelayo kuncike ekulawuleni izinga lokushisa okunembile, ukuphathwa komswakama, ukwakheka komoya, kanye nokuhlela ukusebenza.
Ngokuhlukanisa ngaphambi kokupholisa, ukuguga, kanye nokuqandisa ezindaweni ezihlukene zokushisa, imboni iqinisekisa kokubili ukuphepha kanye nobuhle bokupheka. Lesi sikhungo kumele sivikele ubuqotho be-fiber yemisipha kuzo zonke izigaba zochungechunge olubandayo. Umklamo wobungcweti uvimbela ukuqubuka kwamagciwane ngenkathi ngesikhathi esifanayo uletha inyama yenkomo ethambile nenambithekayo elindelwe ngabathengi banamuhla.
