Emulsifiers n'ibishongesha: Itandukaniro ni irihe?

Kuvanga ibintu bidahinduka ni uburyo bworoshye bwo kubivanga! Niba warigeze kugerageza kubivanga, uzamenya ko amavuta n'amazi bidahura byoroshye. Ariko, hifashishijwe emulsifiers na solubilizers, iki gikorwa gisa n'ikidashoboka kirashoboka.—ariko se si amashaza abiri gusa mu gahu kari mu isaro? Oya rwose! Buri kimwe kigira uruhare rudasanzwe. Nimufate umukandara, abakunzi ba siyansi, mwitegure gusuzuma itandukaniro riri hagati y’ibinyabutabire n’ibishongesha.

Emulsifier ni iki?

Emulsifiers ni zo zihuza isi ya molekile, zihuza mu buryo bw'ubuhanga molekile za peteroli n'amazi akenshi bigenda bitandukanye. Ihame ryazo ni ukugabanya ubushyuhe bw'ubuso hagati y'amazi, bigatuma habaho uruvange ruhamye rwitwa emulsion. Ku rwego rwa molekile, emulsifiers zikunda amfifili—Zifite igice kimwe gikunda amazi (amazi) n'ikindi gikunda amazi (amazi). Ubu buryo bubiri buzifasha kwinjira hagati y'amavuta n'amazi, zigakora uruzitiro rurinda ibitonyanga kugira ngo bitavamo. Ibikoresho bisanzwe ushobora kuba uzi birimo lecithin mu muhondo w'igi, ndetse na lecithin izwi cyane ya soya cyangwa iy'ibihwagari ikoreshwa cyane mu shokora no mu biryo bitetse kugira ngo igire imiterere myiza.

Igishongesha-butabire ni iki?

Nubwo imvange zikunze kwitiranywa n’imvange zikoreshwa mu gushonga, zigira uruhare rutandukanye rwose mu kubyina imvange. Izi mvange zikora neza mu kuboha amavuta akomeye n’amazi kugira ngo zikore umuti ubonerana, aho n’ijisho rityaye cyane ridashobora kubona itandukanyirizo. Mu by’ukuri, imvange zikoresha amavuta zituma amavuta asa n’aho yazimiye burundu mu mazi. Ibi babigeraho bikikije uduce tw’amavuta dufite igishishwa gihumeka amazi, bigahisha mu ruhu rw’amazi, bigatuma bishonga nta n’agace. Ubu buryo butanga umuti aho gutanga umuti. Ushobora kubona imvange zikoreshwa mu bintu bitandukanye, kuva ku byuma bisukura mu maso bisukura amavuta yo kwisiga kugeza ku byuma bitanga impumuro nziza bidasize ibisigazwa, nka polysorbates, alcohol, n’ibindi binyabutabire bya ethoxylated.

Itandukaniro riri hagati yabo ni irihe?

Itandukaniro rikomeye hagati y’ibinyabutabire n’ibinyabutabire bishonga riri mu musaruro wabyo. Ibinyabutabire bifasha mu gukora imiterere mishya no guhuza ibintu, nk'uko bigaragazwa n'ibinyabutabire bihoraho bibaho iyo ibitonyanga by'amavuta bihagaze mu mazi. Umusaruro uba ugaragara nk'ibicu, ariko ibi biterwa nuko byuzuyemo utubuto duto tw'amavuta twunganira amazi akikije. Mu buryo bunyuranye, ibinyabutabire bituma amavuta ashira burundu mu mazi, bigira uruhare runini mu bicuruzwa aho ubwiza ari bwo bw'ingenzi. Binjiza amavuta mu mazi, bigatuma habaho umuti ugaragara nk'ikirahure.
