Ama-colorants ahlukaniswe ngokuyinhloko abe izinhlobo ezimbili:izingulubefuthiodayi.Izingulube zingahlukaniswa zibeizingulube eziphilayofuthiizingulube ze-inorganicngokwesakhiwo sabo.Udayi yizinhlanganisela eziphilayo ezingasetshenziswa kuzincibilikisi eziningi namapulasitiki adayiwe, anezinzuzo ezifana nokuminyana okuphansi, amandla ombala aphezulu, nokungafihli kahle.Kodwa-ke, ukwakheka kwawo kwamangqamuzana okujwayelekile kuncane futhi ukufuduka kujwayele ukwenzeka ngesikhathi sombala.
Ama-colorants angahlukaniswa kabanzi abe ama-pigment kanye nodayi.Ama-pigments yizinto ezinikeza umbala wezinto ezibonakalayo ngokumunca ngokukhetha futhi zibonise ukukhanya.Zingabuye zihlukaniswe zibe yimibala ephilayo (etholakala kumakhompiyutha asuselwa kukhabhoni) kanye nezingulube ze-inorganic (ezihlanganiswe kumaminerali).Ngakolunye uhlangothi, odayi bayinhlanganisela yezinto eziphilayo ezincibilika kuzincibilikisi futhi zingase zisetshenziselwe ukufaka imibala yezinto ezihlukahlukene, kuhlanganise namapulasitiki.Zinezinzuzo zokuminyana okuphansi, amandla okuthayela aphezulu, nokungafihli kahle.Kodwa-ke, ngenxa yobukhulu bawo bengqamuzana, odayi bavame ukufuduka noma baphume igazi ezintweni abagcotshwe kuzo, ikakhulukazi ngaphansi kwezimo ezithile zemvelo, njengamazinga okushisa aphezulu noma ukuchayeka kumakhemikhali athile.
Ngokusho kokuhlaziywa kwezazi zokusebenza kwengqondo, i-83% yombonolokhoabantu bathola ezweni langaphandleis ngokusekelwe ezinzwa zabookuyintokuvela ekuboneni okubukwayo.Kuyabonakala ukuthi ukubaluleka kokubukeka komkhiqizo, ikakhulukaziumbala womkhiqizoukubonakalae, ibaluleke ngokukhethekile.Mayelana nemikhiqizo yokuphakelayo, noma ngabe abasebenzisi basebenzisa umkhiqizo othile wokuphakelayo noma cha, umbala wokubukeka kokuphakelayo udlala indima ebalulekile yokunquma.
Iisiceloama-colorants avame kakhulu embonini yesimanje yokuphakelayo kanye nokufuywa kwezilwane kanye nezilwane zasemanzini.Zimbili izizathu ezilandelayo: okokuqala, ukushintsha umbala wokuphakelayo ngokusebenzisa ama-colorants.Ikakhulukazi ekusetshenzisweni okwandayo kwezithako zokuphakelayo okungezona ezendabuko, ukungeza ama-colorants ukuze kufihlwe imibala engemihle yezithako ezithile ezingezona ezendabuko (njenge-rapeseed meal),ukuzeukuhlinzekela imikhuba yokusebenza kwengqondo, kanye nokwandaeukuncintisana kwemakethe.Ngesikhathi esifanayo, iphinde ibe nendima ekuvuseleleni isifiso sokudla nasekunciphiseni ukudla.Ama-colorants adlala le ndima angabizwa ngokuthi ama- feed colorants.
