Vim li cas cov khoom lag luam gelatinous?
Thaum koj simmer cov nqaij qaib tshiab - ua tiav nrog cov pob txha, tawv nqaij, thiab nqaij - koj rho tawm cov collagen los ntawm cov pob txha. Qhov no collagen nyob rau hauv cov pob txha yog dab tsi ua rau koj cov kua zaub rau gel. Nws yog ntuj kiag li, thiab nws tsuas yog tshwm sim nyob rau hauv nplua nuj, zoo-ua nqaij qaib Tshuag.
