Ua ntej-gelatinized starch, tseem hu ua alpha- starch, yog ib qho txias - dej-soluble modified starch tsim los ntawm cuam tshuam cov crystalline qauv ntawm starch granules los ntawm lub cev los yog tshuaj txhais tau tias. Muab faib ua cov hmoov txhuv nplej siab, nws cov txheej txheem gelatinization muaj peb theem sib txawv: rov qab nqus dej, nqus dej tsis rov qab, thiab cov hmoov txhuv nplej siab. Kev tsim khoom lag luam feem ntau yog siv cov tshuab ziab khaub ncaws, tshuaj tsuag kom qhuav, extrusion, thiab microwave txoj kev. Ntawm cov no, cov txheej txheem rau cov menyuam muaj peev xwm tsim tau tas li, txawm hais tias nws cov gelatinization tus nqi yog kwv yees li 80%; txoj kev tshuaj tsuag entails kuj siv zog heev; txoj kev extrusion nta cov cuab yeej siv qis dua thiab cov khoom lag luam tawm nrog qis viscosity; Thaum txoj kev microwave ua tiav ob qho tib si gelatinization thiab ziab los ntawm microwave cua sov.
Vim nws solubility sai hauv dej txias, cov hmoov txhuv nplej siab no tau siv dav hauv kev lag luam khoom noj khoom haus -tshwj xeeb yog txhawm rau txhim kho cov dej noo thiab kev ntxhib los mos hauv cov khoom ci, tiv thaiv kev tawg thiab muab cov thickening nyob rau hauv cov khoom noj khov, stabilizing thiab thickening sauces, thiab ua kom yooj yim tawg sai sai hauv cov khoom noj. Hauv kev lag luam tshuaj, nws ua haujlwm raws li cov ntsiav tshuaj khi, hloov cov tshuaj ib txwm siv los txhim kho cov ntsiav tshuaj cov qauv kev ntseeg siab thaum txo qis cov kev mob tshwm sim. Industrially, nws yog siv nyob rau hauv foundry xuab zeb binding, textile sizing, thiab dej -raws li architectural txheej; nyob rau hauv kev lag luam tshuaj pleev ib ce, nws ua hauj lwm los hloov talc nyob rau hauv zus tau tej cov tawv nqaij - phooj ywg lub cev hmoov. Qhov zoo ntawm cov khoom kawg yog cuam tshuam los ntawm ntau yam, nrog rau cov khoom siv raw siv, qhov concentration ntawm cov hmoov txhuv nplej siab slurry, thiab ziab kub.
