Umurongo w’uguhingura ibifungurwa vy’ibikoko utuma gelatinization y’inyama z’ingurube zigenda neza kandi igatanga ivyamwa vy’umukara bihinduwe, bifise amazi akomeye y’amazi n’ibikorwa vyo gufatanya. Kubera ko amazi menshi ari menshi, turashobora kwongerako ibirungo vyinshi (nk’ibinure, ibitoke vy’umukara, n’ibindi) ku kintu. Muri ico gihe nyene, kubera ko ifise igikorwa gikomeye cane kuruta igiti c’umusemburo gisanzwe, umubare w’imisemburo yongeweko mu gihe c’uguhingura ibintu bishobora kugabanywa cane. Ivyo bitanga umwanya mwinshi wo guhitamwo ibindi bikoresho vya mbere. Ibikoresho vy’agaciro kanini bishobora gutorwa mu nzira kugira ngo bisubirire ivyo bikoresho bizimvye, bishobora kugabanya cane ibiciro ataco bihinduye ku buryo bw’ibicuruzwa.
Kubera ihuriro ry’amaproteine n’ivy’umubiri, ntivyoroshe gutakazwa mu gihe co kugaburira. Iyo enzymes zituma umuntu adafungura neza ari zo zisenya igihimba c’umubiri, iyo poroteyine irarekurwa, kandi ubushobozi bw’amaproteine buragwira. Ivyo bikoresho vy’ubuhinga bw’ibikoko vy’ibikoko na vyo nyene biratuma poroteyine idakora, irakoresha ibintu vyinshi bitera umugera, kandi ihindura imiterere y’iporoteyine y’igihe ca gatatu, igaca igabanya igihe c’amazi c’iyo poroteyine iri mu mara. Ku bijanye n’ibikoko bita ruminates, gutera amaproteine y’amarume, ni ukuvuga proteine y’umukara, ishobora kwirinda gutera ubumara bw’amonia no gutuma poroteyine ikoreshwa neza.
