Yendani pansi pa msewu uliwonse wa supermarket ndipo mupezagelatin wodyedwakusonkhanitsa pamodzi mwakachetechete gawo lodabwitsa la zomwe timadya ndi kumwa ngati mankhwala - maswiti, ma marshmallow, yogurt, makeke otsekemera, ndi makapisozi ofewa omwe ali mu botolo lanu lowonjezera. Komabe, pa chinthu chofala kwambiri, opanga mankhwala ochepa okha ndi omwe amadziwa bwino momwe chikopa kapena fupa la nyama yolimba limakhalira ufa wokoma komanso wosungunuka nthawi yomweyo.

Kumvetsetsa momwe gelatin yodyedwa imapangidwira kumathandiza opanga chakudya kuwunika momwe zinthuzo zimagwirira ntchito, kusinthasintha kwa gulu, komanso kudalirika kwa kupanga. Ubwino wa zinthu zopangira, kuyeretsa, kukonza, kuyeretsa, ndi kusakaniza zonse zimatha kukhudza mphamvu ya gel, kukhuthala, kumveka bwino, mtundu, fungo, ndi momwe imagwirira ntchito. Ichi ndichifukwa chake zinthu ziwiri za gelatin zomwe zili ndi mphamvu yofanana ya gel zimatha kugwira ntchito mosiyana pakusakaniza, kuphika, kuyika, kapena kukhazikitsa. Bukuli likufotokoza njira yonse kuyambira collagen yaiwisi mpaka gelatin yomalizidwa ya chakudya, pamodzi ndi mawu aukadaulo omwe nthawi zambiri amakumana nawo posankha gelatin.

Kodi Gelatin Yodyedwa Ndi Chiyani Kwenikweni?

Gelatin yodyedwa ndi puloteni yomwe imapezeka chifukwa cha hydrolysis pang'ono ya collagen - puloteni yopangidwa ndi nyama yomwe imapezeka pakhungu, mafupa, ndi minofu yolumikizana. Si yowonjezera yopangidwa ndi nyama. Pakupanga, kapangidwe ka collagen kamagawika pang'ono kukhala ma protein omwe amatha kunyowa m'madzi, kusungunuka pansi pa kutentha koyenera, ndikupanga gel yosinthika pamene yankho likuzizira. Khalidweli limapatsa gelatin ntchito yake yapadera muzinthu monga ma gummies, marshmallows, jellies, ndi zakudya zotsekemera za mkaka.

Pali mabanja awiri amalonda, omwe amatanthauzidwa ndi momwe collagen yosaphika imakonzedwera musanachotsedwe:

• Mtundu A (kukonza asidi): umapangidwa kudzera mu kukonza asidi wa zinthu zopangira zokhala ndi kolajeni yambiri. Mtundu A wa gelatin nthawi zambiri umakhala ndi malo okwera a isoelectric, nthawi zambiri mkati mwa pH 7–9, kutengera zinthu zopangira ndi momwe zimakhalira popanga.
• Mtundu B (kukonza alkali / laimu): umapangidwa kudzera mu kukonza alkali, nthawi zambiri pogwiritsa ntchito laimu wolamulidwa kapena alkaline system. Gelatin ya mtundu B nthawi zambiri imakhala ndi malo otsika a isoelectric, nthawi zambiri pafupifupi pH 4.7–5.5.

Gelatin ya Mtundu A ndi Mtundu B yonse ingapangidwe ngati zosakaniza za mtundu wa chakudya pamene zipangizo zoyenera ndi njira zowongolera za mtundu wa chakudya zikugwiritsidwa ntchito. Kusankha kuyenera kuganizira pH ya kapangidwe kake, mphamvu ya maluwa, kukhuthala, komwe nyama imachokera, momwe zosakanizazo zimagwirizanirana, momwe zimagwirira ntchito, ndi zofunikira pa satifiketi mongaHALAL kapena Kosher.

Collagen ili ndi kapangidwe ka triple-helix komwe kamathandizira kulimbitsa minofu yolumikizana ndi nyama. Pakupanga gelatin, kuchiza ndi kulamulira kutentha kumasokoneza kapangidwe kameneka ndikutulutsa mamolekyu a gelatin okhala ndi magawidwe osiyanasiyana a molekyulu. Mphamvu ya gel yomalizidwa ndi kukhuthala kwake zimakhudzidwa ndi zinthu zingapo, kuphatikizapo momwe zinthu zopangira zilili, mphamvu ya mankhwala okonzekera, kutentha kwa kuchotsa, nthawi yochotsera, gawo lochotsera, kutentha, ndi kusakaniza pambuyo pake. Ngakhale gelatin yopangidwa kuchokera ku gulu lomwelo la zinthu zopangira zinthu imatha kuwonetsa magwiridwe antchito osiyanasiyana.

Chifukwa Chake Njira Yopangira Imatsimikiza Ubwino

Makhalidwe abwino a Gelatin amakhazikitsidwa panthawi yopanga. Magawo asanu ofunikira kwambiri:

• Kusankha ndi kutsata zinthu zopangira. Gelatin yoyenerera chakudya iyenera kupangidwa kuchokera ku zinthu zopangira zovomerezeka zokhala ndi collagen zomwe zili zoyenera msika womwe mukufuna ndipo zimathandizidwa ndi zikalata zoyenera kutsata. Kutengera komwe nyama imachokera komanso komwe ikupita, zikalata zothandizira zitha kuphatikizapo zolemba zoyambira, zikalata za ziweto, satifiketi za Halal kapena Kosher, ndi zikalata zowopsa za TSE/BSE pazinthu zochokera ku ng'ombe.
• Kuchiza msanga (asidi kapena alkali). Kuchiza msanga kumayeretsa ndi kufupikitsa kapangidwe ka collagen, zomwe zimapangitsa kuti ikhale yoyenera kuchotsedwa bwino. Kuchiza kosakwanira msanga kungathandize kuchepetsa mphamvu yotulutsa kapena kusiya zinthu zosafunikira zomwe sizili collagen, pomwe kuchiza mopitirira muyeso kungawononge unyolo wa mapuloteni ndikuwononga zokolola, mphamvu ya Bloom, kapena kukhuthala.
• Kutulutsa madzi otentha. Kolajeni imathiridwa ndi madzi ofunda (nthawi zambiri 50–80 °C) kuti itulutse gelatin. Kutentha, nthawi, ndi pH zimayika kugawa kwa molekyulu - motero mphamvu ya gel ndi kukhuthala kwa chinthu chomaliza.
• Kuyeretsa ndi kukhutitsa thupi. Chotsitsacho chimasefedwa, kuchotsedwa ayoni, ndikuphwanyidwa kuti chichotse fungo, mtundu, ndi zinthu zosasungunuka. Kulamulira bwino apa ndi komwe kumapereka ufa woyera, wopanda phulusa, komanso wopanda tizilombo toyambitsa matenda.
• Kuyeretsa, kuumitsa, ndi kugaya. Gawo lililonse limafuna njira zoyendetsera ntchito zomwe zafotokozedwa. Kusakonza bwino zinthu pasadakhale kungachepetse mphamvu yotulutsa kapena kupangitsa kuti pakhale zinyalala zosafunikira. Kusasefa kokwanira kungakhudze kuyera bwino, pomwe kutentha kwambiri panthawi yowuma kapena kuyanika kungawononge unyolo wa mapuloteni, kuchepetsa magwiridwe antchito, komanso kupangitsa kuti utoto usawonekere bwino. Chifukwa chake, kudalirika kwa kupanga kuyenera kuwunikidwa kudzera munjira zolembedwa, zolemba zamagulu, njira zoyesera, ma COA otsatizana, kuchuluka kwa satifiketi, ndi magwiridwe antchito opangira.

Chofunika kwambiri, palibe chilichonse mwa izi chomwe chili chosankha. Kudumpha kapena kufulumizitsa kukonza zinthu musanagwiritse ntchito kumasiya zokometsera ndi zinyalala; masamba osasefa bwino amasanduka chifunga; kuumitsa kwambiri kumapangitsa kuti puloteniyo iwoneke ngati caramel ndipo imapangitsa mtundu kukhala wakuda. Udindo wa wogulitsa wodalirika ndikuchita zonse zisanu, gulu lililonse, mofanana - ndichifukwa chake malipoti owunikira ndi makasitomala ofunikira ndi ofunika kwambiri ngati pepala lofotokozera.

Kumene Ufa Umatha: Ntchito Zenizeni

Molekyulu yofananayo imawonekera pazinthu zosiyanasiyana, ndichifukwa chake wogulitsa wosinthasintha ndi wofunika:

Popeza mtundu umodzi ukhoza kutumikira zingapo mwa izi nthawi imodzi, opanga ambiri amasankha mtundu umodzi wa maluwa m'magawo awo kuti zinthu ziyende bwino komanso kuti zinthu ziyende bwino.

• Maswiti. Maswiti a gummies, maswiti a jelly, ndi marshmallows amadalira gel yosungunuka komanso yosalala ya gelatin.
• Zakudya za mkaka ndi zokometsera. Yogurt, mousse, ndi panna cotta zimagwiritsa ntchito mphamvu zochepa za gel kuti zikhale zosalala komanso zosalala popanda syneresis.
• Ma softgels a mankhwala ndi makapisozi olimba. Magulu olamulidwa ndi kukhuthala amapanga chipolopolo cha makapisozi ndi matrix a ma softgels (onani buku lathu lotsogolera la gelatin ya mankhwala).
• Zakudya zopatsa thanzi komanso zothandiza. Ma protein bar, zakumwa, ndi ma gummies amapereka collagen ndi zosakaniza zothandiza kudzera mu mphamvu ya gelatin yomangirira ndi kupangira gelling.
• Zakumwa ndi zinthu zopangidwa ndi nyama. Gelatin imayeretsa madzi ndi vinyo, imayika ma aspic ndi ma terrines, ndipo imanyamula ma collagen peptides mu zakumwa zogwira ntchito kuti ikhale ndi mapuloteni oyera.

Kuchokera ku Riboni mpaka Ufa Wotulutsidwa: Kuwongolera Ubwino

Kupanga gelatin youma ndi gawo limodzi chabe la njira yopangira. Asanatulutse, gawo lililonse lomalizidwa liyenera kuyesedwa motsatira zomwe zafotokozedwa. Gelatin yoyenerera chakudya iyenera kuyesedwa motsatira malamulo oyenera azakudya ndi zomwe makasitomala akufuna, pomwe magulu azamankhwala angafunike kuyesedwa kwina motsatira zolemba zoyenera za mankhwala. Njira zolembedwa, zida zoyesedwa, zolemba zotsatirika, ndi machitidwe okhazikika zimathandiza kutulutsidwa kwa batch kodalirika.

Kukula kwa kupanga kumatha kuthandizira kusinthasintha ngati kukuphatikizidwa ndi zida zokhazikika, kusaka zinthu zopangira zoyendetsedwa bwino, magawo odziwika bwino opanga, kuyesa koyenerera kwa labotale, ndi kasamalidwe ka gulu lolembedwa. Kwa opanga omwe amagwiritsa ntchito njira yomweyo pa nthawi yayitali yopangira, kusinthasintha m'malo otsatizana nthawi zambiri ndikofunikira kwambiri kuposa kuwunika mtengo wokha. Chifukwa chake ogula ayenera kuwunikanso ma COA angapo, magwiridwe antchito a zitsanzo, kulekerera kwa specification, ndi njira zowongolera kusintha akamayesa wopanga gelatin.

Mafunso Ofunsidwa Kawirikawiri

Kodi njira yopangira zinthu imatenga nthawi yayitali bwanji?

Nthawi yonse yopangira imadalira zinthu zopangira ndi njira yokonzekera. Kukonza asidi nthawi zambiri kumakhala kochepa, pomwe kukonza zikopa za ng'ombe kapena mafupa pogwiritsa ntchito alkaline kungatenge milungu ingapo. Kuchotsa, kuyeretsa, kuika zinthu m'magulu, kuyeretsa, kuumitsa, kusakaniza, ndi kuyesa zinthu zomalizidwa kumafuna nthawi yowonjezera. Nthawi yopangira malonda imadaliranso nthawi yopangira, kulongedza, kulemba zikalata, ndi zofunikira pakutulutsa zinthu.

Kodi gelatin ingapangidwe kuchokera ku nsomba kapena zomera?

Gelatin yodyedwa yogulitsidwa imachokera ku nyama yopangidwa ndi kolajeni. Gelatin ya nsomba ilipo (yomwe imasungunuka pang'ono, yothandiza pazinthu zotentha), pomwe agar ndi carrageenan ndi njira zina zopangira gelling kuchokera ku zomera - onani kufananiza kwathu kwagelatin yodyedwa motsutsana ndi agar agarGelken imaperekanso gelatin ya nsomba kuti igwiritsidwe ntchito popanga zinthu zomwe zimafunika kusungunuka pang'ono kapena zomwe sizichokera ku ng'ombe, kotero kuti chinthu choyenera chopangira ma gelling chikugwirizana ndi nyengo yanu ndi zomwe mukufuna.

Kodi ndiyenera kuyang'ana chiyani pa gelatin COA?

Mphamvu ya maluwa, kukhuthala, chinyezi, phulusa, pH/IEP, kuchuluka kwa tizilombo toyambitsa matenda, ndi malire a heavy-metal. Unikani magulu angapo, osati limodzi, kuti muwone kusinthasintha. Tsimikiziraninso kuti palibe tizilombo toyambitsa matenda tosavomerezeka, ndipo, potumiza kunja, kuti satifiketiyo ikugwirizana ndi malamulo a msika womwe mukupita.

Mapeto

Ndiye, kodi gelatin yodyedwa imapangidwa bwanji? Ndi collagen, yokonzedwa bwino, yochotsedwa m'madzi ofunda, yoyeretsedwa, youmitsidwa, ndikuphwanyidwa kukhala ufa wofanana ndi chakudya - ndipo njirayo, osati chizindikiro, ndiyo imasankha ngati ikugwira ntchito bwino pa intaneti yanu.

Ngati mukufuna kapena mukufunanso gelatin, pemphani chitsanzo chaGelatin wodyedwa wa Gelken(80–320 Tumphuka, ungathe kusintha, chakudya ndi mankhwala) ndipo uzigwiritse ntchito motsatira muyezo wanu wamakono. Ndipo mphamvu ya duwa ikadzakhala funso lanu lotsatira, chitsogozo chathu chakumvetsetsa mphamvu ya maluwa a gelatinikuthandizani kuwerenga mfundo monga formulator.
