Lub ntsiab tseem ceeb ntawm cov tsiaj gelatin yog gelatin peptide protein.Ib qho ntawm nws cov purity tsawg yog hu ua pob txha kua nplaum. Cov kua nplaum yog lub cev nkig, tawv, solidified.Collagen yog cov protein insoluble hauv dej.Tom qab cua sov thiab lwm yam kev kho mob, nws yuav dhau los ua lwm hom protein hu ua colloid, uas tuaj yeem yaj hauv dej kub thiab muaj cov khoom sib txuas.Cov zaj duab xis ntawm cov pob txha kua nplaum yog ruaj khov thiab elastic tom qab tsim.

Cov pob txha nplaum hlaws feem ntau yog siv los ua cov nplaum, electroplating additives, sizing agents, coagulant AIDS.

Thaum siv cov pob txha pob txha, ua ntej siv tib lub ntim los yog dej me ntsis (zoo dua nrog dej kub) kom ntub cov pob txha cov kua nplaum rau li 10 teev, kom cov nplaum nplaum ua mos, thiab tom qab ntawd rhaub rau li 75 ℃, kom nws tuaj yeem ua tau. Siv cov kua nplaum ua kua.Qhov piv ntawm cov kua nplaum rau dej yuav tsum tau txiav txim siab raws li qhov xav tau viscosity.Cov kua nplaum kub yuav tsum tsis txhob siab dhau, qhov kub ntawm ntau tshaj 100 ℃ yuav txo qhov viscosity vim molecular degradation, kua nplaum aging metamorphism. Cov pob txha pob txha muaj kab los nag hauv kev siv, yog li nws yuav tsum tau siv thaum ntxiv dej zoo rau kev sib xyaw tsim nyog, txhawm rau kho viscosity thiab fluidity
