Ukadaulo Wokonza Nsomba Zozizira
Monga dziko lokhala ndi nyanja, Indonesia ili ndi kuthekera kwakukulu kwa usodzi. Komabe, kuthekera kumeneku kudzayamikiridwa bwino ngati kuthandizidwa ndi ukadaulo wokonza womwe ungasunge ubwino wa nsomba kuyambira pomwe zigwidwa mpaka zitafika kwa ogula. Chimodzi mwa ukadaulo wofunikira kwambiri komanso wogwiritsidwa ntchito kwambiri ndi kukonza nsomba zozizira. Kuzizira sikungokhala "kozizira," koma ndi njira yamakono yosungira yomwe cholinga chake ndi kuchepetsa kuwonongeka kwa zamoyo, mankhwala, ndi tizilombo toyambitsa matenda m'nsomba. Ndi kukonza bwino, nsomba zozizira zimatha kusunga thanzi labwino, kapangidwe kake, mtundu, ndi kukoma kofanana ndi kwa nsomba zatsopano.
Mfundo zoyambira zoziziritsira nsomba
Nsomba ndi chakudya chomwe chimawonongeka mosavuta chifukwa cha kuchuluka kwa madzi, ntchito ya ma enzyme, komanso mafuta omwe amatha kusungunuka. Kuzizira kumagwira ntchito pochepetsa kutentha mpaka madzi omwe ali mu minofu ya nsomba asandulika ma crystals a ayezi. Madzi akatsekedwa ngati ayezi, ntchito ya tizilombo toyambitsa matenda imachepa kwambiri ndipo zochita za enzyme zimachepa. Komabe, kuzizira sikupha tizilombo tonse; kumangoletsa kukula kwawo. Chifukwa chake, ukhondo (ukhondo) ndi kagwiritsidwe ntchito koyamba zimakhalabe zinthu zomwe zimapangitsa kuti zinthu zikhale bwino.
Kuthamanga kwa kuzizira kumakhudza kwambiri ubwino. Kuzizira mofulumira kumapanga ma kristalo a ayezi ang'onoang'ono, ogawidwa mofanana, zomwe zimapangitsa kuti minofu ya nsomba isawonongeke kwambiri. Mosiyana ndi zimenezi, kuzizira pang'onopang'ono kumapanga ma kristalo akuluakulu a ayezi omwe amatha kuswa ma cell, zomwe zimapangitsa kuti kapangidwe kake kakhale kosalala komanso kutayika kwa madzi (kutayika kwa madzi) akasungunuka.
Magawo a kukonza nsomba zozizira
Ukadaulo wokonza nsomba zozizira nthawi zambiri umakhala ndi njira zingapo zogwirizana. Kachitidwe ndi tsatanetsatane wa njirayi zimatha kusiyana kutengera mtundu wa nsomba ndi mtundu wa chinthucho (chonse, fillet, steak, kapena chokonzedwa), koma nthawi zambiri zimaphatikizapo:
1. Kulandira zinthu zopangira
Nsomba ziyenera kufufuzidwa kuti zione ngati zili zatsopano, kukula kwake, momwe zilili, fungo lake, mtundu wake, komanso kutentha kwake. Ndi bwino kuti nsombayo ikhale ili mu unyolo wozizira kuyambira pamene inakwera sitimayo. Nsomba ikagwidwa msanga, imakhala yabwino kwambiri kuti iziziziritsidwa.
2. Kutsuka ndi kusanja
Kutsuka kumachitika kuti kuchotse mamina, dothi, magazi, ndi tizilombo toyambitsa matenda pamwamba. Kusanja kumachitika malinga ndi kukula ndi ubwino kuti zitsimikizire kuti kuzizira kumachitika mofanana.
3. Kuchotsa udzu (kudula) ndi kudula
Pazinthu zambiri, matumbo amafunika kuchotsedwa kuti achepetse kuipitsidwa ndi fungo. Chogulitsacho chingasinthidwe kukhala nsomba zopanda mutu, zidutswa, kapena zidutswa zonse malinga ndi zomwe msika ukufunikira.
4. Chithandizo cha kuzizira chisanachitike
Makampani ena amagwiritsa ntchito kuviika mu njira zinazake (monga madzi oundana, njira zamchere wofatsa, kapena zinthu zololedwa) kuti zithandize kusunga mtundu, kuchepetsa kukhuthala, kapena kukonza mphamvu yosunga madzi. Gawoli liyenera kutsatira malamulo ogwiritsira ntchito chitetezo cha chakudya.
5. Kuzizira
Ichi ndiye chimake cha ndondomekoyi. Kutentha kwa chinthu chomwe mukufuna kugwiritsa ntchito nthawi zambiri kumakhala pafupifupi -18°C kapena kutsika, kutengera miyezo ya kampani komanso zolinga zosungira.
6. Kupaka ndi kulemba zilembo
Cholinga cha phukusili ndi kuteteza nsomba kuti zisakhudzidwe ndi mpweya (mpweya), kuipitsidwa, komanso kusowa madzi m'madzi pamwamba. Zolembazo zimakhala ndi mfundo zofunika monga mtundu wa chinthu, kulemera kwake, tsiku lopangira, ndi nambala ya malo kuti zidziwike bwino.
7. Kusunga ndi kugawa zinthu mufiriji
Zinthu zimasungidwa m'malo ozizira ndipo zimagawidwa pogwiritsa ntchito magalimoto oziziritsa. Kukhazikika kwa kutentha ndikofunikira kwambiri kuti ubwino usawonongeke panthawi yonyamula.
Njira ndi zida zoziziritsira
Njira zosiyanasiyana zoziziritsira zapangidwa kuti zigwirizane ndi mphamvu yopangira, mawonekedwe a chinthu, komanso ndalama zogwirira ntchito.
1. Choziziritsira Mpweya (ABF)
Njirayi imagwiritsa ntchito mpweya wozizira kwambiri komanso woyenda bwino. ABF imagwiritsidwa ntchito kwambiri chifukwa imasinthasintha kukula kwa zinthu zosiyanasiyana, imakhala ndi mphamvu zambiri, ndipo ndi yoyenera kupanga mafakitale. Vuto lake ndilakuti ngati kulongedza sikunakonzedwe bwino, chinthucho chimatha kutaya madzi m'thupi, zomwe zingayambitse "kutentha mufiriji."
2. Choziziritsira mbale
Mafiriji a mbale amagwiritsa ntchito mbale zoziziritsidwa zachitsulo zomwe zimamatira pa chinthucho, zomwe zimathandiza kuti kutentha kusamuke mwachangu kudzera mu kukhudzana mwachindunji. Ndi oyenera zinthu zooneka ngati matabwa kapena mapaketi ofanana. Ubwino wake ndi kuzizira mwachangu komanso kogwira mtima komanso chinthu chofanana. Komabe, njira iyi siisinthasintha kwambiri pa mawonekedwe osagwirizana.
3. Kuzizira Mwachangu Kwa Munthu Payekha (IQF)
IQF imaundana zidutswa za nsomba kuti zisamamatire pamodzi. Imagwiritsidwa ntchito kwambiri popanga zidutswa zazing'ono, zodulidwa, kapena zinthu zowonjezera phindu. IQF imapanga zabwino kwambiri chifukwa cha kuzizira kwake mwachangu, zomwe zimathandiza ogula kuti azitha kutenga mosavuta zomwe akufuna (popanda kusungunula chilichonse), komanso kuchepetsa kuwonongeka akamaigwira.
4. Kuzizira kwa Cryogenic
Njirayi imagwiritsa ntchito nayitrogeni yamadzimadzi (LN2) kapena kaboni dioksidayokisaidi (CO2) pozizira mofulumira kwambiri. Imapangitsa kuti kapangidwe kake kasungidwe bwino, koma pamtengo wokwera wogwirira ntchito. Nthawi zambiri imagwiritsidwa ntchito pazinthu zapamwamba kapena pakafunika kuthamanga kwambiri.
Kuphimba: kuteteza pamwamba pa nsomba zozizira
Kuphimba pamwamba pa nsomba zozizira ndi ayezi wochepa powamiza kapena kuwapopera ndi madzi ozizira komanso oyera. Cholinga chake ndikuchepetsa kukhuthala kwa mafuta, kupewa kusowa madzi m'thupi, ndikuteteza pamwamba kuti pasapse ndi kutentha mufiriji. Kuphimba pamwamba kwambiri kuyenera kulamulidwa, chifukwa kungakhudze kulemera konse ndi chilungamo cha malonda. M'misika yambiri, kuchuluka kwa kuphimba pamwamba kumayendetsedwa ndipo kuyenera kufotokozedwa momveka bwino.
Mavuto a khalidwe: kusintha kwa mapuloteni ndi kusungunuka kwa mafuta
Ngakhale kuti kuzizira kumawonjezera nthawi yosungira nsomba, nsomba zozizira zimatha kuwonongekabe mu nthawi yosungidwa. Mavuto awiri akuluakulu ndi awa:
– Kuchepa kwa mapuloteni: kusintha kwa kapangidwe ka mapuloteni kumatha kuchepetsa kusinthasintha ndi mphamvu yosunga madzi, zomwe zimapangitsa kuti kapangidwe kake kakhale kouma kapena kosweka pambuyo posungunuka. Kusinthasintha kwa kutentha mufiriji kumawonjezera vutoli.
– Kusungunuka kwa mafuta: Mu nsomba zonenepa monga tuna, mackerel, kapena salimoni, kusungunuka kwa mafuta kumatha kubweretsa fungo loipa. Kuyika bwino, kuphimba bwino, komanso kusungidwa bwino pa kutentha kochepa kumathandiza kuchepetsa kusungunuka kwa mafuta.
Unyolo wozizira ndi chizindikiro cha kupambana
Kukonza bwino nsomba zozizira sikumathera ku fakitale. Unyolo wozizira uyenera kusungidwa kuyambira pa sitima yosodza, malo ogulitsira nsomba, fakitale, malo osungiramo zinthu zozizira, kugawa, ndi kugulitsa. Kuswa unyolo wozizira kungayambitse njira ya "kusungunuka-kuzizira", zomwe zimawononga kapangidwe kake, zimawonjezera kutayika kwa madzi, komanso zimawonjezera chiopsezo cha kukula kwa tizilombo toyambitsa matenda panthawi yosungunuka.
Kuti zinthu zisamavutike, kuyang'anira kutentha pogwiritsa ntchito makina olembera deta kapena njira zowunikira nthawi yeniyeni, njira zopezera ndi kutsitsa katundu mwachangu, komanso maphunziro a ogwira ntchito pa ukhondo ndi kusamalira zinthu zozizira ndizofunikira.
Miyezo yachitetezo cha chakudya ndi machitidwe amakampani
Makampani opanga nsomba zozizira nthawi zambiri amagwiritsa ntchito njira zoyendetsera chitetezo cha chakudya monga GMP (Good Manufacturing Practices), SSOP (Sanitation Standard Operating Procedures), ndi HACCP (Hazard Analysis Critical Control Point). HACCP ndi yofunika kwambiri pozindikira malo ofunikira, monga kutentha kozizira, kuyeretsa madzi osambira, kuipitsidwa ndi zida, ndi kutentha kosungirako kozizira. Kuphatikiza apo, kulondola kuchokera ku zinthu zopangira kupita ku chinthu chomaliza ndikofunikira kwambiri, makamaka m'misika yotumiza kunja.
Zatsopano ndi zochitika zamtsogolo
Ukadaulo wokonza nsomba zozizira ukupitirirabe kusintha. Zinthu zingapo zomwe zikubuka zikuphatikiza kugwiritsa ntchito vacuum ndi ma CD osinthidwa mumlengalenga, kuyang'anira kutentha kochokera ku IoT, kugwiritsa ntchito mphamvu moyenera mu makina oziziritsira, ndi kugwiritsa ntchito zinthu zina (mafupa, khungu, ndi mitu) kuti ziwonjezere phindu lazachuma ndikuchepetsa zinyalala. Kuphatikiza apo, kufunikira kwa ogula kwa zinthu zokonzeka kuphikidwa komanso zokonzeka kudyedwa kukuyambitsa zatsopano mumitundu yazogulitsa komanso machitidwe oziziritsa mwachangu komanso aukhondo.
Kutseka
Ukadaulo wokonza nsomba zozizira ndi njira yofunika kwambiri yosungira ubwino wa nsomba, kukulitsa kufikira kwa msika, komanso kuchepetsa kutayika kwa nsomba pambuyo pokolola. Chinsinsi cha kupambana chili mu kukhala zatsopano kwa zinthu zopangira, kuzizira mwachangu komanso molondola, kulongedza bwino, komanso kuzizira kosalekeza. Mwa kukhazikitsa miyezo yoyenera ya ukhondo ndi njira zotetezera chakudya, nsomba zozizira zimatha kukhala chinthu chabwino kwambiri chomwe chili chotetezeka, chopatsa thanzi, komanso chopereka phindu lalikulu pazachuma ku makampani osodza aku Indonesia.
