I-gelatin iveliswa njani?

Mna.Ukulungiswa kwezinto eziluhlaza​

I-Gelatinimveliso iqala ngeemveliso eziphuma kwizilwanyana (izikhumba, amathambo, imisipha), ezicocwayo, zisuswe ioyile, zize zityunyuzwe. Izikhumba zeehagu (30–50%) i-collagen) kwaye amathambo eenkomo axhaphake kakhulu. Izinto eziluhlaza ziyahlolwa ukuqinisekisa ukuba azinazo izifo okanye izinto ezingcolisayo, inyathelo elibalulekileyo kwi-gelatin yokutya/yeyeza.

II.Iindlela ze-Hydrolysis​

I-asidi ye-hydrolysis (uhlobo A lwegelatin) iphatha izinto nge-hydrochloric acid kangangeeyure ezingama-24-48. I-alkaline hydrolysis (uhlobo lwe-B gelatin) isebenzisa amanzi elayimu kangangeeveki ezi-3-8. I-enzyme hydrolysis, indlela entsha, isebenzisa iiproteases ukuphula ii-collagen bonds, inciphisa ixesha lokucubungula kunye nempembelelo yokusingqongileyo. Indlela nganye ivelisa i-gelatin enamandla ahlukeneyo okuqhakaza kunye neeprofayili ze-amino acid.​

III.Ukucocwa kunye nokomiswa​

Emva kwe-hydrolysis, isisombululo se-gelatin siyahluzwa ukuze kususwe ukungcola, sisuswe i-ion ukuze kulungiswe i-pH, size sixinaniswe phantsi kwe-vacuum. Ukomisa nge-spray (umoya oshushu) okanye ukomisa nge-freeze (ubushushu obuphantsi) kuguqula ulwelo lube ngumgubo okanye amaphepha. Imveliso yokugqibela ivavanywa amandla e-bloom, i-viscosity, kunye nokhuseleko lwe-microbiological ngaphambi kokuba ipakishwe kwimizi-mveliso ethile.​
