Itandukaniro riri hagati yo gutandukanya ibice, gukwirakwiza hydrogenation no gupima amavuta n'ibinure.
Gutandukanya ibice, hydrogenation, no gupima imiterere y’amavuta n’ibinure ni ikoranabuhanga ritatu ry’ingenzi mu guhindura imiterere y’ibinyabutabire n’iy’ibinyabutabire by’amavuta n’ibinure kugira ngo bihuze n’ibikenewe bitandukanye by’inganda z’ibiribwa. Itandukaniro ry’ibanze riri mu mahame anyuranye bakoresha mu guhindura imiterere y’amavuta n’ibinure. Hasi, turagaragaza igereranya ryumvikana ry’itandukaniro ryabyo binyuze mu mbonerahamwe n’ibisobanuro birambuye.
Incamake y'Itandukaniro ry'Ishingiro
| Umutungo | Gutandukanya ibice | Hydrogenation | Igenamiterere ry'ibimenyetso |
| Kamere | Impinduka ku mubiri | Impinduka mu butabire | Impinduka mu butabire |
| Ihame | Gutandukanya ibintu bishingiye ku itandukaniro ry’aho ibintu bitandukanye bishongesha triglycerides binyuze mu gukonjesha, gushushanya no kuyungurura. | Kongeramo hydrogen ku migozi ibiri ya aside irike idafite amazi mu mubiri hakoreshejwe uburyo bwa catalyst. | Gutunganya aside irike ku mugongo wa glycerol mu buryo butunguranye cyangwa mu cyerekezo binyuze mu gikorwa cya catalyst cyangwa enzyme. |
| Intego | Gutandukanya amavuta mo ibice bifite aho bishongesha cyane (stearin) n'ibifite aho bishongesha bike (olein). | Kongera urugero rwo gushonga kw'amavuta kugira ngo ava mu mazi akagera mu bintu bikomeye cyangwa bikomeye; kongera ubushobozi bwo kudahinduka kw'ibinure. | Guhindura imiterere y'ubuziranenge bw'amavuta n'uburyo aside irike ikora nta guhindura imiterere yayo. |
| Ingaruka ku binyabutabire | Nta mpinduka mu miterere ya aside irike. | Impinduka mu miterere y'ibinyabutabire bya aside irike: aside irike idafite ibinure → aside irike yuzuye; ishobora gukora aside irike idafite ibinure. | Nta mpinduka mu miterere ya aside irike ku giti cyayo, ahubwo ni impinduka mu miterere yayo ku mugongo wa glycerol. |
| Ibiranga Ibicuruzwa | Shaka ibintu bibiri cyangwa byinshi bifite imiterere itandukanye (urugero: palm olein na palm stearin bivuye mu mavuta ya palm). | Shaka amavuta ya hydrogeni afite imiterere ikomeye kandi ahamye kurushaho. | Shaka amavuta afite imikurire mishya n'imiterere mishya, nka margarine idafite amavuta ya trans na shortening. |
| Igereranya ryoroshye | Nk'uko gusiga amavuta hanze mu gihe cy'itumba, gutandukanya amavuta y'amazi n'igice cy'amavuta cyakonje. | Nk’uko bikomeza molecule zidahindagurika kugira ngo zirusheho kuba “zikomeye” kandi “zihamye”. | Nk'uko uvangavanga ikarita (aside ibinure) kugira ngo ubone ukuboko gushya (amavuta mashya). |
Ibisobanuro birambuye
1. Gutandukanya ibice
• Igitekerezo cy'ingenzi: Gutandukana, ntabwo ari uguhinduka.
• Uburyo: Shyushya amavuta buhoro buhoro kugira ngo ayashongeshe, hanyuma uyakonjeshe buhoro buhoro ku bushyuhe runaka. Triglycerides ifite aho ishongesha cyane izabanza gushonga, igakora uduce duto. Utu duce duto (stearin) dushobora gutandukanywa n'amavuta adafunze (olein) binyuze mu kuyungurura cyangwa gutandukanya amavuta.
• Ingero z'ishyirwa mu bikorwa:
o Gutandukanya amavuta ya palme: Iyi ni yo ikoranabuhanga rikoreshwa cyane mu gutandukanya. Amavuta ya palme ashobora gutandukanya kugira ngo haboneke palme olein (ikoreshwa mu guteka, gukaranga) na palme stearin (ikoreshwa mu gusya margarine, gukaranga, n'amavuta ya confectionery).
o Gutandukanya amavuta: Bitanga amavuta meza cyane, akoreshwa mu gukora amafunguro meza.
• Ibyiza: Uburyo bwo gukora ibintu busanzwe, nta mpinduka za shimi zihari, nta bintu bigabanya ubukana bw'ibinyabutabire, kandi umusaruro ni karemano.
2. Gutera umwuka wa hydrogen
• Igitekerezo cy'ingenzi: Ongeramo hydrogen kugira ngo amavuta "akomere" kandi "abe akomeye".
• Uburyo: Mu gihe cy'ubushyuhe bwinshi, umuvuduko mwinshi, no mu gihe hari katalyst y'icyuma (ubusanzwe nikeli), gaze ya hydrogene inyuzwa mu mavuta y'amazi. Hydrogen yongera imigozi ibiri mu migozi ya aside irike idafite amavuta, ikagabanya cyangwa igakuraho imigozi ibiri.
o Hydrogenation igice: Ingano ebyiri ntizuzura neza, kandi umubare munini wa aside irike ikomoka kuri trans ukorwa muri iki gikorwa. Bitewe n'ingaruka mbi za aside irike ikomoka kuri trans ku buzima, yarahagaritswe mu bihugu byinshi no mu turere twinshi.
o Hydrogenation yuzuye: Imigozi ibiri iba yuzuye cyane, ahanini ikora aside y'ibinure byuzuye (aside stearike), hafi ya yose nta aside y'ibinure ya trans. Amavuta yuzuye hidrogen aba akomeye cyane kandi aroroshye, kandi akenshi agomba kuvangwa n'amavuta y'amazi cyangwa agahindurwa binyuze mu ihinduranya rya ester kugira ngo ahindure imiterere yayo.
• Ingero z'ishyirwa mu bikorwa:
o Gukora ibiryo bito bito na margarine: Hindura amavuta ya soya y'amazi, amavuta ya rapeseed, n'ibindi mu buryo buto bwo guteka no gusiga.
o Kunoza uburyo amavuta ahora akoreshwa: Kongera igihe cyo gukaranga amavuta n'ibiribwa birimo amavuta.
• Ingaruka mbi: Ikora aside irike yangiza ikoreshwa mu gukurura (hydrogenation y’igice) kandi igatakaza aside irike y’ingenzi.
3. Isoko rya Ester
• Igitekerezo cy'ingenzi: "Guhinduranya", guhindura imiterere ya triglycerides.
• Uburyo: Mu gihe hakorwa na catalyst ya shimi (nka sodium methooxide) cyangwa lipase, aside irike glycerides iri mu mavuta "irasenyuka", hanyuma aside irike ikongera guhurizwa ku mugongo wa glycerol kugira ngo habeho molekile nshya za triglyceride.
o Ihindagurika rya ester ritunguranye: Aside ibinure ihinduka mu buryo butunguranye hagati ya molekile zose.
o Ihererekanya rya ester riyobowe: Mu bihe runaka (nk'ubushyuhe bugenzurwa), inzira yo gukosora yerekeza mu cyerekezo cyifuzwa.
• Ingero z'ishyirwa mu bikorwa:
o Gukora ihindagurika rya ester ridafite ibinure bya trans na margarine: Iyi ni yo gahunda igezweho yo guhinduranya ester. Mu gukora ihindagurika rya ester hagati ya stearin yuzuye hydrogenated (idafite aside trans) n'amavuta y'amazi, ibinure bya pulasitiki bifite imiterere ikwiye kandi bidafite aside trans bishobora kuboneka.
o Kunoza uburyo ibisimbuza amavuta ya kakao bihura.
o Guhindura imiterere ya kristu y'amavuta y'inka n'amavuta kugira ngo byongere imikorere yabyo mu guteka.
• Ibyiza: Bishobora guhindura cyane imiterere y'amavuta hatabayeho gukora aside irike ya trans, bigatuma biba ingenzi mu gukoresha ikoranabuhanga rya hydrogenation.
Niba ushaka gutandukanya amavuta mo ibice bifite aho ashongeshereza hatandukanye, koresha uburyo bwo kuyagabanyamo ibice. Niba ushaka gutuma amavuta y'amazi akomera kandi agakomera, ubusanzwe akoreshwa mu buryo bwa hydrogenation, ariko menya ikibazo cya aside irike ya trans. Niba ushaka guhindura ubukana, imiterere n'uburyo amavuta ahinduka utarinze gukoresha hydrogenation, ishobora gukora aside irike ya trans, guhindura imiterere y'amavuta ni bwo buryo bwiza. Mu nganda zigezweho za peteroli, ubu buryo butatu bukunze guhuzwa kugira ngo hakorwe amavuta akora neza ahuye n'ibikenewe bitandukanye byihariye.
