Ntuj pigments yog cov khoom noj xim xim uas muab rho tawm los ntawm cov nroj tsuag, tsiaj txhu, los yog kab mob los ntawm lub cev, xws li curcumin, beta carotene, liab poov xab liab, thiab lwm yam. Tsav los ntawm thoob ntiaj teb "cov ntawv huv" thiab noj qab nyob zoo, cov pigments ntuj tau hloov zuj zus los ntawm cov khoom siv hluavtaws rau cov khoom xyaw tseem ceeb rau cov tuam txhab zaub mov los tsim cov khoom lag luam siab - kawg thiab sib txawv.
Hauv cov ntawv thov zaub mov, cov xim ntuj muaj ntau yam xws li dej haus, khoom ci, khoom noj nqaij, khoom qab zib, thiab lwm yam. Piv txwv li, curcumin muab cov dej haus cog rau lub teeb daj daj, cov poov xab liab muab cov khoom noj nqaij muaj xim zoo nkauj, thiab phycocyanin dhau los ua cov khoom siv kos npe hauv siab -kawg ice cream. Tus nqi pH, kev ua haujlwm kub, thiab teeb pom kev zoo ntawm cov khoom noj sib txawv ua rau cov kev cai nruj ntawm kev ruaj ntseg ntawm cov xim - qhov no yog cov txheej txheem ntawm cov khoom siv raw khoom thiab tus yuam sij los muab cov kev daws teeb meem.
Raws li lawv cov peev txheej thiab cov qauv tshuaj, cov pigments ntuj tau muab faib ua peb pawg: carotenoids (xws li beta carotene thiab lycopene), uas muaj cov lipid solubility muaj zog thiab tsim nyog rau oily systems; Polyphenols xws li anthocyanins thiab curcumin yog dej - soluble thiab pH rhiab heev, ua rau lawv haum rau kev hloov xim; Lwm hom (xws li chlorophyll thiab cov poov xab liab) muaj thermal stability zoo heev thiab muaj peev xwm ua haujlwm siab - kub. Txoj kev lag luam tam sim no tau hloov pauv los ntawm "ib qho pigment mov" mus rau "cov kev pabcuam mis sib xyaw", kov yeej cov kev sib tw ruaj khov los ntawm kev siv thev naus laus zis xws li microcapsules thiab emulsification, thaum tshawb nrhiav txoj hauv kev tsim khoom ruaj khov xws li microbial fermentation thiab biosynthesis. Raws li koj tus khub raw khoom thoob ntiaj teb, peb muab ntau yam ntawm cov xim ntuj thiab cov khoom siv thev naus laus zis los pab txhim kho ntsuab ntawm cov khoom noj khoom haus kev lag luam saw.
Yog tias koj xav tau cov ntaub ntawv ntxiv ntawm cov ntsiab lus ntau lawm, cov kev qhia tshwj xeeb, lossis cov qauv kuaj, thov koj xav nug. Peb yuav txhawb koj cov khoom innovation thiab tsim tus nqi ua ke nrog cov khoom ruaj khov.
