Hloov Starch
Nws tseem yog hu ua starch derivatives, uas yog tsim los ntawm lub cev, tshuaj los yog enzymatically kho nrog cov hmoov txhuv nplej siab ib txwm hloov, ntxiv dag zog rau lossis ua rau cov khoom tshiab los ntawm molecular cleavage, rearrangement los yog qhia cov pab pawg tshiab.Muaj ntau txoj hauv kev los hloov cov hmoov txhuv nplej siab, xws li ua noj, hydrolysis, oxidation, bleaching, oxidation, esterification, etherification, crosslinking thiab lwm yam.
Kev hloov kho lub cev
1. Pre-gelatinization
2. Kev kho hluav taws xob
3. Kev kho cua sovKev hloov kho tshuaj
1. Esterification: Acetylated starch, esterified nrog acetic anhydride lossis vinyl acetate.
2. Etherification: Hydroxypropyl starch, etherified nrog propylene oxide.
3. Acid kho starch, kho nrog inorganic acids.
4. Alkaline kho hmoov txhuv nplej siab, kho nrog inorganic alkaline.
5. bleached starch, daws nrog hydrogen peroxide.
6. Oxidation: Oxidized starch, kho nrog sodium hypochlorite.
7. Emulsification: starch sodium Octenylsuccinate, esterified nrog octenyl succinic anhydride.
