Sida mid ka mid ah waxyaabaha aadka loo isticmaalo ee dawooyinka loo isticmaalo, bararka hantida kaabsulka jelatin waa sifo jidheed oo muhiim ah oo saamaynaysa heerka sii daynta daawada iyo noolaha. Bararka waxaa loola jeedaa ifafaale halka qolof kaabsoosha ay nuugo biyaha oo ay marto ballaarinta mugga marka la taabto dhexdhexaad aqueous. Habkani wuxuu si toos ah u go'aamiyaa kaabsoosha wakhtiga kala go'a iyo dhaqanka kala dirida daroogada.
Habka bararka ee kaabsal jelatin waxa loo qaybin karaa saddex marxaladood: heerka qoynta bilowga ah, heerka bararka degdega ah, heerka bararka dheellitirka. Marka kaabsalku uu taabto dhexdhexaad aqueous, kooxaha hydrophilic ee silsiladaha molecular ee jelatin (sida -COOH iyo -NH2) waxay si degdeg ah u sameeyaan bonds haydarojiin leh molecules biyaha, qoyan dusha kaabsulka. Intaa ka dib, unugyaraha biyuhu waxa ay galaan qaab-dhismeedka shabakadda saddex-geesoodka ah ee jelatin iyada oo loo marayo osmosis, taas oo keenaysa korodhka masaafada u dhaxaysa silsiladaha molecular iyo balaadhinta mugga kaabsulka. Daraasaduhu waxay muujiyeen in 37 darajo, saamiga bararka ee kaabsal jelatin uu gaari karo 200%{10}}300%, ugu dambeyntii samaynta qaab-dhismeedka jel u eg.
Sababaha saameeya bararka jelatin kaabsal madhan inta badan waxa ka mid ah isha jelatin, heerka iskutallaabtu{0}isku xidhka, heerkulka jawiga, iyo pH dhexdhexaad ah. Ilaha kala duwan ee xayawaanka (sida maqaarka doofaarka, maqaarka lo'da, ama lafaha kalluunka) waxay keenaan kala duwanaansho ka kooban halabuurka amino acid iyo qaybinta miisaanka kelli ee jelatin, taas oo si toos ah u saamaysa awoodda nuugista biyaha. Iskutallaab dhexdhexaad ah -isku xidhiddu waxay wanaajin kartaa awoodda farsamada kaabsulka,laakin iskutallaabta xad dhaafka ah{4}}isku xidhiddu waxay hor istaagi kartaa gelitaanka biyaha waxayna yaraynaysaa heerka bararka. Korodhka heerkulku waxa uu dedejiyaa dhaqdhaqaaqa molecular waxana uu kor u qaadaa habka bararka, halka aashitada ama deegaanka alkaline laga yaabo in ay wax ka beddelaan xaaladda silsiladaha molecular ee jelatin, taas oo saameynaysa fuuqbaxa.
Codsiyada la taaban karo, bararka kaabsal jelatin waxay saameyn laba geesood ah ku leeyihiin sii deynta daroogada. Dhinaca kale, bararka ku habboon ayaa hubiya in kaabsalku si degdeg ah u kala firdhiyo mareenka caloosha iyo mindhicirka, kor u qaadida kala dirida daroogada. Dhanka kale, bararka aadka u degdega ah wuxuu u horseedi karaa daadinta daroogada, halka bararka aan ku filnayn uu sababi karo sii-deynta daroogada aan dhamaystirnayn. Sidaa darteed, iyadoo la hagaajinayo nooca jelatin, lagu daro balaastikada (sida glycerin), ama lagu daro surfactants, dabeecadda bararka kaabsalku si sax ah ayaa loo xakameyn karaa si loo buuxiyo shuruudaha sii deynta daawooyinka kala duwan.
Horumarka tignoolajiyada habaynta, cilmi baadhista bararka kaabsal jelatin waxay ka soo gudubtay ifafaale makroscopic una gudubtay hababka molecular. Codsiga farsamooyinka falanqaynta casriga ah, sida Kalorimetry Scanning Differential (DSC) iyo Falanqaynta Mechanical Dynamic (DMA), ayaa bixisay qalab xoog leh oo muujinaya isbeddelada is-beddelka ee silsiladaha molecular inta lagu jiro habka bararka. Mustaqbalka, iyada oo loo marayo injineernimada hidaha ee jelatin la beddelay ama abuurista isku-dhafka leh polymers-ka dabiiciga ah, waxaa la filayaa in hababka kaabsal ee cusub ee leh jawaabaha bararka caqli-gal ah la horumarin doono, sii wadida horumarinta tignoolajiyada gudbinta daroogada.
