Inodaidzwawo kuti starch derivatives, iyo inogadzirwa nemuviri, kemikari kana enzymatic kurapa neanowanikwa starch kuchinja, kusimbisa kana kukanganisa zvivakwa zvitsva ne molecular cleavage, kurongazve kana kusuma mapoka matsva anotsiva.Pane nzira dzakawanda dzekugadzirisa sitachi yechikafu, sekubika, hydrolysis, oxidation, bleaching, oxidation, esterification, etherification, crosslinking uye nezvimwe.
Kuchinja muviri
1. Pre-gelatinization
2. Kurapa kwemwaranzi
3. Kurapa kwekupisa
Kugadziriswa kwemakemikari
1. Esterification: Acetylated starch, esterified neacetic anhydride kana vinyl acetate.
2. Etherification: Hydroxypropyl starch , etherified ne propylene oxide.
3. Acid yakagadziriswa starch , inobatwa neinorganic acids.
4. Alkaline yakarapwa starch, inobatwa neinorganic alkaline.
5. Bleached starch, yakabatwa nehydrogen peroxide.
6. Oxidation: Oxidized starch, inobatwa ne sodium hypochlorite.
7. Emulsification: starch sodium Octenylsuccinate, esterified ne octenyl succinic anhydride.
