Monga tonse tikudziwa, yogati imagwiritsidwa ntchito ngati zowonjezera chakudya, ndipo gelatin ndi imodzi mwa izo.
Gelatin imachokera ku mapuloteni a collagen omwe amapezeka kwambiri pakhungu la nyama, tendon ndi mafupa.Ndi puloteni ya hydrolyzed yochokera ku kolajeni mu minofu yolumikizana ndi nyama kapena minofu ya epidermal.Pambuyo pothandizidwa ndi khungu la nyama kapena fupa, gelatin, mankhwala a hydrolyzed a collagen, amatha kupezeka.Mwanjira ina, collagen imasinthidwa kukhala chinthu chosungunuka m'madzi pambuyo pakusweka pang'ono kwa ma intermolecular bond chifukwa cha kutentha kosasinthika kwa hydrolysis.
Kusiyana kwa isoelectric point pakati pa mtundu A gelatin ndi mtundu B wa gelatin ndi chifukwa cha kusiyana kwa chiwerengero cha acidic ndi alkaline amino acid mu gelatin chifukwa cha mankhwala osiyanasiyana a asidi.Ndi mphamvu yofananira ya odzola, mtundu wa B gelatin uli ndi kukhuthala kwapamwamba kuposa mtundu A gelatin.Gelatin imasungunuka m'madzi ozizira, koma imatha kuyamwa madzi ndikutupa mpaka nthawi 5-10.Gelatin imachulukitsa granularity ndi kuchepa kwa mphamvu ya mayamwidwe amadzi.Gelatin kukhala gelatin njira pambuyo Kutentha kutentha kuposa kusungunuka kwa gelatin, ndi gelatin kukhala odzola pambuyo kuzirala.
Monga chowonjezera cha chakudya, gelatin edibleamagwiritsidwa ntchito kwambiri popanga yogurt.Gelatin ndi yabwino stabilizer ndi thickener.Mayankho a gelatin amapangitsa yogurt kukhala wokhuthala komanso kosavuta kusunga.
Malinga ndi gulu la yogurt, kugwiritsa ntchito gelatin mu yogurt makamaka kumaphatikizapo zinthu zitatu:
1. Coagulated yoghurt: Chopangidwa ndi yoghurt yakale ndi choyimira.Coagulated yogurt ndi mankhwala popanda demulsification pambuyo nayonso mphamvu.Gelatin imapangitsa zinthu kukhala zosalala bwino zomwe zinthu zina monga zowuma zokhala ndi asidi zalephera kupereka.
2. Yogati wothira: Zogulitsa zomwe zimapezeka pamsika, monga Guanyiru, Changqing, Biyou, ndi zina zotero, zonse ndi yogati yowawitsidwa.Pazinthu zotere, gelatin imakhalapo ngati yokhuthala, ndipo kumayambiriro kwa kukonza timasungunula gelatin mu 65 ℃.Kuchuluka kwa gelatin kuli pakati pa 0.1-0.2%.Gelatin imatsutsana ndi homogenization ndi kutenthedwa kwa kutentha pakupanga yogati, kupereka mankhwalawo ndi mamasukidwe oyenera.
3. Kumwa yogurt: Kumwa yogati ndikuti timachepetsa kukhuthala kwa mankhwalawa kudzera mu homogenization pambuyo nayonso mphamvu.Chifukwa cha kuchepetsa mamasukidwe akayendedwe, ayenera kugwiritsa ntchito colloid kuonetsetsa bata la mankhwala ndi kuchepetsa stratification ya yogurt mkati alumali moyo.Zomwezo zikhoza kuchitika ndi ma colloid ena.
Pomaliza, kuwonjezera gelatin ku yoghurt kungalepheretse kulekana kwa whey, kukonza bungwe ndi kukhazikika kwa chinthu chomalizidwa, komanso kuti chikwaniritse mawonekedwe abwino, kukoma ndi kapangidwe.Gelken amatha kupereka gelatin yabwino kwambiri ya yogurt.
