(1) cmc nwere ezigbo nkwụsi ike

Na nri oyi dị ka potan na ice cream, ọ nwere ike ijikwa usoro akpụrụ mmiri, na-abawanye mmụba ma na-enwe agbaze, nwee ezigbo uto, ma na-achacha mma ma na-acha ọcha.

Na ngwaahịa mmiri ara ehi, ma ọ bụ mmiri ara ehi, mmiri ara ehi mkpụrụ osisi ma ọ bụ yogọt, ọ nwere ike ime ihe dị mgbagwoju anya, nke bara uru na nkwụsi ike nke emulsion ma melite nguzogide protein.

(2) cmc nwere ike gbakwunye ya na ihe ndị ọzọ na emils

Na nri na ngwaahịa ọ overage, ndị na-eme nchọpụta na-eji usoro dị iche iche, dị ka: Gọta GerTin, Byctrins, wdg.

(3) cmc nwere pseudoplastity
