Inkoni y’ikawa ni igikoresho ciza co guteka ikawa, akenshi gikorwa mu gukanda uruvange rw’ifu y’ikawa, isukari, umunyu, n’ikintu gishobora gusenyuka (nk’ikinyobwa citwa maltodextrin canke igiti citwa gum). Ingingo ngenderwako nyamukuru yayo ni iyo kurekura ningoga uburyohe bw’ikawa biciye mu kuyisesa mu mazi akanye canke ashushe, bikaba bituma umuntu ashobora kuyinywa ubwo nyene. Ibi bikurikira birasigura ingingo ngenderwako y’ibikorwa vyayo bivanye n’ubuhinga bw’ibintu, uburyo bwo gusenyura, n’ingene bishobora gukoreshwa.
I. Igizwe n'ibikoresho n'imiterere y'umubiri
Ibirungo nyamukuru vy'inkoni y'ikawa ni:
1.Instant coffee powder: Itanga uburyohe n’akamoto k’ishimikiro k’ikawa kandi akenshi yumishwa mu mfuruka- canke ifumbishijwe kugira ngo ishobore gusenyuka cane.
2.Ibintu bitera uburyohe n’ibitera umunyu: Nk’isukari, ibisubirira isukari, canke ibitari-vy’amata, bihindura uburyohe kandi bikongera uburyohe iyo bimaze gusenyuka.
3.Ibifatanya: Nk’ivyo bita maltodextrin canke hydroxypropyl methylcellulose (HPMC), bituma inkoni y’ikawa imera mu gihe c’ugukanda kandi igakwiragizwa neza iyo ishikiwe n’amazi.
Ivyo birungo birakandagizwa n’inguvu nyinshi kugira ngo bibe inkoni ikomeye. Uburemere bwayo n’uburemere bwayo biragira ico bikoze ata guca ku ruhande ku rugero rwo gusenyuka kwayo. Nk’akarorero, igihimba gifise utunogo kiratuma amazi yihuta kwinjira, mu gihe igitigiri c’ibintu bifatanya gikoreshwa gitegerezwa gutuma amazi agira uburinganire mu gukomera no mu gusenyuka.
II. Amahame n'uburyo bwo gusenyura
Ugusenyuka kw’inkoni z’ikawa bishingiye ku gukwiragira no gukwiragira:
1.Ukwinjira kw’amazi: Iyo amazi ashushe canke akanye akora ku ruhande rw’inkoni y’ikawa, amazi yinjira mu binogo vy’imbere biciye mu gikorwa c’imitsi, agasenyura ifu y’ikawa ishobora gusenyuka n’ibindi bihimba bishobora gusenyuka.
2.Molecular diffusion: Ama molecule y’ikawa yanyuze arakwiragizwa kubera ubudasa bw’ivyiyumviro, bikagira umuti umwe. Ubushuhe bwinshi buratuma inguvu z’inyigisho z’ibihimba vy’umubiri zirushirizaho kandi zigatuma ibintu vyihuta gusenyuka (nk’akarorero, amazi ashushe akenshi asenyura inkoni y’ikawa yose mu masegonda 5-10).
3.Suspension na emulsification: Iyo hariho ibirungo vy’amavuta canke vy’amavuta, ibirungo vy’amavuta birabuza ibice gutera kandi bikaba bituma umuntu agira uburyohe bwiza.
Birabereye kumenya ko inkoni z’ikawa zishobora gusenyuka mu mazi akanye-zishobora kubamwo ibindi bintu bikora ku mubiri (nk’ivyo bita carrageenne) kugira ngo bigabanye ugushikama kw’amazi no gutuma amazi ashobora gusenyuka neza iyo ubushuhe buri hasi.
III. Ivyiza vyo gukoresha n'ivyiza
Inkoni z’ikawa zari zagenewe gutorera umuti ububabare bw’ikawa y’agaciro, iyo ikawa ikaba yizigira ibiyiko canke ibipapuro. Ivyiza vyavyo ni ibi:
Ivyo bishobora gutwarwa: Bipakiwe umwumwe wese, birabereye gukoreshwa hanze, ku kazi canke mu rugendo.
Iteguye-gukoresha-: Nta bikombe vyo gupima canke ibikoresho vyo gutera ivyatsi bisabwa; gusa wongere ku mazi ukanywa.
Uburyohe Busanzwe: Ivyo guhingura ibintu mu nganda biragenzura imigereranyo y’ibirungo, bikaba bituma inkoni yose igira uburyohe bumwe.
Vyongeye, hari ibintu bimwebimwe bishasha (nk’inkoni z’ikawa zifise imiti igabanya ubukana bw’indwara canke ubuhinga bwo gutegura ikawa mu buryo bukonje) vyararushirije kwagura ibikorwa vyavyo, nk’ugutuma ikawa ishobora kumara igihe kirekire canke kwigana ubutunzi bw’ikawa iherutse gusembwa.
IV. Imipaka n'Iterambere
Naho inkoni z’ikawa zibereye kandi zikora neza, muri rusangi uburyohe bwazo buraba buke kuruta ubw’ikawa iherutse gusembwa, kandi hari ibintu bimwebimwe birimwo isukari nyinshi be n’ibindi bintu vyongerwako. Amabwirizwa y'iterambere ry'imbere ashobora kubamwo:
Isukari nto-/nta-ivyongeweko: gufasha abaguzi bafise ubuzima-bazirikana;
Ubuhinga bwihariye bwo gutegura inzoga zikonje: gutuma uburyohe bw’amazi akanye bumera neza;
Ibikoresho bishobora gusenyuka: kugabanya ingaruka mbi ku bidukikije.
Mu ncamake, inkoni y’ikawa ishika ku bumenyi bwo kunywa ikawa bukeyi mu gufatanya ubuhinga bw’ibintu n’inguvu z’ugusenyuka. Ingingo ngenderwako zayo n’amabwirizwa yo gutera imbere birabandanya gutuma habaho ubuhinga bushasha mu bijanye n’ubuhinga bwo gutegura ibifungurwa vyoroshe.
