Teb: Weeping jelly (syneresis) tej zaum yuav tshwm sim los ntawm ntau cov kua qaub, qhov chaw cia uas sov dhau, qhov chaw cia kub hloov pauv, lossis txheej ntawm paraffin tuab heev.
Dab tsi yog ua rau syneresis hauv jams?
Hauv kev ua noj, syneresis yog tam sim ntawd tso cov dej noo uas muaj nyob rau hauv cov protein molecules, feem ntau tshwm sim los ntawm kub dhau, uas dhau-hardens lub plhaub tiv thaiv. Cov dej noo hauv qhov nthuav dav thaum cua sov. Lub plhaub tawv protein pops, tshem tawm cov dej noo.

Cov txheej txheem ntawm qhov tshwm sim no tau piav qhia siv ob txoj hauv kev, uas yog polymer thiab colloidal sciences.
Koj tiv thaiv syneresis hauv jelly li cas?
Ib txoj hauv kev los tiv thaiv kev sib koom ua ke yog txhawm rau nce osmotic siab ntawm cov gel xws li ua kom cov gel polymer concentrationTsis tas li, txo lub network siab. Qhov no txhais tau hais tias tswj kev sib txuas ntawm cov polymers hauv cov gel los ntawm kev tswj cov txheej txheem gel.
Puas yog kev daws teeb meem?
Jam is ib hom colloid. Cov khoom me me ntawm cov txiv hmab txiv ntoo qab zib raug tshem tawm hauv dej thiab pectin, uas tsim cov khoom qab zib qab zib.
