Isitashi Esishintshiwe
Kubuye kubizwe ngokuphuma kwesitashi, okukhiqizwa ngokuphathwa ngokomzimba, ngamakhemikhali noma nge-enzymatic ngesitashi somdabu ukushintsha, ukuqinisa noma ukuphazamisa izakhiwo ezintsha ngokuqhekeka kwamangqamuzana, ukuhlela kabusha noma ukwethulwa kwamaqembu amasha angena esikhundleni.Kunezindlela eziningi zokushintsha isitashi sokudla, njengokupheka, i-hydrolysis, i-oxidation, i-bleaching, i-oxidation, i-esterification, i-etherification, i-crosslinking njll.
Ukuguqulwa komzimba
1. I-Pre-gelatinization
2. Ukwelashwa ngemisebe
3. Ukwelashwa kokushisaUkuguqulwa kwamakhemikhali
1. I-Esterification: Isitashi se-acetylated, i-esterified ne-acetic anhydride noma i-vinyl acetate.
2. I-Etherification: I-Hydroxypropyl isitashi, i-etherified nge-propylene oxide.
3. Isitashi esiphathwe nge-Acid, siphathwa ngama-acids angaphili.
4. Isitashi esiphathwe nge-alkali, esiphathwa nge-alkaline engaphili.
5. Isitashi esine-bleached, siphathwa nge-hydrogen peroxide.
6. I-Oxidation: isitashi esenziwe nge-oxidized, siphathwa nge-sodium hypochlorite.
7. Emulsification: isitashi sodium Octenylsuccinate, esterified nge octenyl succinic anhydride.
